Autism 101- Coordination

Greetings Earthlings! 🙂

Today I’m going to talk to you about coordination difficulties and the spectrum.

Did you know: Roughly 80% of autists have issues with motor coordination?

And I am no exception! 😛

To be honest, I needn’t even write anything for this post- a host of gifs would fairly accurately sum up my experiences of coordination! 😛

reporter-falls-on-ice-winter-sports-fails

I drop things more easily, I fall over a LOT, bump into things, walk sideways into people I’m walking alongside, fumble a little longer with buttons, laces, hair clips etc. People have often thought I’ve been drunk on nights out (although I don’t drink) when coordination trouble presents itself- giddiness has a habit of rendering me less coordinated for some reason! 😛

These incidents happen so often it becomes another part of daily life- you trip over your feet for no reason, laugh and keep walking! 😛

You might think I’m exaggerating but it happens all the time! Even my dogs have noticed- I once fell flat on my face on a walk and my normally attentive German Shepherd just stood and laughed, waiting for me to get back up! 😛

I’ve always been a little slower than my peers when it comes to mastering my finer motor skills. From my very first skip I’ve struggled with my coordination issues.

My mother often reminds me of how I used to screw my face up in concentration after dance classes in my attempts to master the skill. I would try and try and try to skip around the room, but kept falling over my own two feet!

Don’t get me started on the struggle to add in a skipping rope! 😛

But nevertheless, each time I fell, I got back up again and persisted until I mastered it- and then you couldn’t keep me from skipping!

This has always been my experience of coordination. I struggle a little bit longer than my peers to develop my motor skills, but with persistence, master them I will. Tying my shoelaces, riding a bike, learning to drive, knitting- all these skills took time to master, but I got there in the end 🙂

Now if I could just master walking in heels, I’d be flying! 😛 😉

Top tip– Keeping on top of sleep, thirst and hunger can really help to keep your coordination in check. In addition to acting loopy if I fall victim to these, I find that my equilibrium can also be affected.

But what do scientists have to say about these coordination issues?

The underlying cause of these issues is poorly understood, however, recent studies suggest that motor coordination issues in autism are likely linked to abnormal neural connections in the brain. Remember the synapse (or connecting junction point between two neurons) which we discussed last week? Autist’s have an overabundance of these bad boys compared with normally developing peers.

So how does the synapse affect motor coordination?

Motor learning and control is influenced by a specific group of neurons known as purkinje cells. Purkinje cells, (located in the cerebellum- an area heavily involved in motor control), receive signals from climbing fibers- a type of neuron which carries information from the body to the brain. These climbing fibers detect changes or disturbances in our environment, such as changes in space or the position of nearby objects, and relay this information to the purkinje cells. Purkinje cells then emit inhibitory signals at synapses so to modify motor movements accordingly.

In autism however, the efficacy of purkinje cells to influence motor change is greatly reduced.

Normally, each purkinje cell receives input from a single climbing fiber. Autists have too many synapses connecting the brain, and so the purkinje cell receives signals from multiple climbing fibers. This confuses the purkinje cell, which in turn alters the efficacy of corrective signals. Like a game of Chinese Whispers, the more people involved (i.e. synapses and climbing fibers), the more the message get’s lost in translation.

To give an example, if you were walking along and someone threw a ball at you, climbing fibers will alert the purkinje cells to tell the body to move out of the way. In autism….well, the signal to do this get’s scrambled on route to the brain, aaaaand… you’ll likely get hit in the face! 😛

^^^^Story of my life right here! 😛

At the end of the day, whilst coordination problems can be incredibly frustrating, persist and you will get there 🙂

Never give up- ride that bike, drive that car, skip like there’s no tomorrow!! Autism only limits us if we allow ourselves to be limited 🙂

Inside the Autistic Brain

Greetings Earthlings! 🙂

Today I’m going to dive into the physiology of the autistic brain to explain what’s actually going on at the neurological level. I’ve touched on aspects of the science in previous posts, but I wanted to give you a quick overview post where the main points in the one place 🙂

So let’s get down to some science! 🙂

Hyper-connected Neurons:

Scientific evidence suggests that neurons in the autistic brain are hyper-connected. Specifically, studies indicate that autists have too many synapses in the brain. The synapse is basically a gap or a junction between two neurons where chemical messengers (neurotransmitters) carry information like a ferry from one neuron to the next. It looks a little bit like this:

Image result for synapse

During normal brain development, about half of the synapses we are born with are “pruned” off. In autism, this process is slowed down, and so autistic children have an excessive amount of synapses compared with their neurotypical peers. As these connections are essential to communication between neurons, this can greatly effect how the brain works and processes information.

Dysfunction at the Junction:

In addition to possessing an excessive number of synapses, communication at these neuronal junctions is also impaired in the autistic brain.

Animal studies have indicated that synapses function differently in the autistic brain as a result of genetic mutation. Mutations cause certain proteins to be absent in autism- proteins that are essential to the normal functioning of the synapse. As a consequence of this, the transmission of information between neurons is affected, resulting in a number of social and behavioral issues.

Think of physical junctions on a busy road- if something goes wrong at the junction, a chain of chaos will ensue!

Image result for junction crash gif

Hyper-excitable Neurons:

Research shows that in many cases of autism, neurons in certain regions of the brain are more excitable than others. This means that these neurons are more sensitive to stimulation. For example, the neurons located in the sensory cortex of the brain (which processes sensory information such as smell), are more sensitive and excitable than other neurons. This is kind of like how a person can be more ticklish in some parts of the body than another- the nerves in the underarm are more excitable than those of the arm.

This sensitizes the autistic brain to all kinds of stimuli as discussed here.

Dysregulated Neurotransmitter levels:

As previously mentioned, information travels across the synapses in the brain via chemical messengers known as neurotransmitters. In the autistic brain, the levels of these neurotransmitters are dysregulated- or out of sync. Research indicates that individuals with autism tend to have higher levels of excitatory neurotransmitters (e.g. glutamic acid) and lower levels of calming neurotransmitters (e.g. GABA, serotonin) causing neurons in the autistic brain to fire excessively. In addition to this, levels of the neurohormone (a chemical that acts as both a hormone and neurotransmitter) oxytocin, which plays an influential role in trust and social behaviours, are also out of balance. Moreover, dopamine (a neurotransmitter which can both calm and excite) is also dysregulated in autism. Together, the action of biochemicals like these influences a number of autistic behaviours and issues such as ADHD, mood, appetite, sleep, anxiety, sensory processing, social behaviours, learning, memory and emotional responses.

Male vs Female Brain

Perhaps one of the most fascinating things that I have discovered about autism are the anatomical differences between the brains of the male and female autist. Brain imaging studies have revealed that autistic women have brains that are anatomically similar to neurotypical male brains, and the brains of male autists share anatomical similarities to those of neurotypical female brains.

In short- this indicates that men with autism have feminine brains, and women with autism have masculine brains!!!

I know!!!!

It sounds weird, but it makes a world of sense. Oftentimes I’ve felt like I had a male brain growing up- my tomboyish interests, my fashion sense, my preference for male company, my inability to walk in heels; it all fits!

Strange but true! 🙂

There we have it Earthlings- hope you enjoyed this brief insight into the physiology of the autistic brain 🙂 There is no clear mechanism through which autism acts, these are just some of the likely pathways involved. I’ll explore other possible mechanisms in a later post.

Have a good week everyone! 🙂

Autism 101-Sensory Processing

Greetings Earthlings! 🙂

So today I’m going to briefly introduce you to the issue of sensory processing for people on the spectrum. This is a very broad topic, but I’ll expand on the issues in more detail at a later stage 🙂

Many individuals on the autistic spectrum struggle to process every day sensory information. Sounds, textures, smells, lights, even colours (boys in particular struggle to process the colour yellow) can overload the nervous system and greatly upset us, effect our behavior or even trigger a meltdown.

But why?

In autism, our senses can be either hyper or hypo sensitive (sometimes even both) to stimuli at different times. Our senses are heightened- smells are stronger, sounds are louder. As a result of this, stimuli reverberate all the more intensely in our brains.

Think of the brain as a computer server at exam time where everyone is logging in at once. Too much information has been entered into the system, but the server can only cope with so much. The entire system becomes overwhelmed and the server crashes.

Here’s just a quick video simulation of sensory overload.

Warning for those on the spectrum– this video contains flashing lights, bright colours and loud, sudden noises

For me personally, I have many (mild) issues with sensory processing. Smells, tastes and textures are a daily struggle. For example, I don’t think I’ll ever be able to eat a salad as the smell alone makes me want to throw up- I’m dreading what pregnancy may one day bring! 😛 😉

Loud or irritating noises, (especially repetitive ones), too can be a challenge. Don’t get me started on the shock I get when a passing bus makes that giant hiss/woosh sound or a car honks the horn unexpectedly!! 😛

Most days, you’re lucky and the offending stimulus passes quickly, but other times it can get the better of you. I recently had a near meltdown on holiday from a cocktail of excessive heat, hunger, exhaustion and social frustration.

Top Tip– Keep on top of your hunger/thirst. I’ve discovered this past year that an excess of either will make me act really loopy! 😛

When you’re hit by sensory overload, it feels as though your head is caught in a vice grip. Your mind is screaming, unable to focus on anything else but the source of discomfort.

The worst part of it I find is coming across as a complete basket case when overloaded. You don’t get the most sympathetic of looks when you complain about a persistent noise- few can understand how it’s making your brain hurt.

So what does science have to say about sensory processing?

Sensory integration involves three basic sensory systems:

The tactile system (touch)- comprises a series of nerves passing information from the skin to the brain
The vestibular system (sound)- comprises a series of structures in the inner ear involved in movement detection
The proprioceptive system-a series of receptors in the muscle (proprioreceptors) which feed information to the brain about the body’s position

These three systems share a close but complicated relationship which allow us to experience, process and respond to different stimuli. Dysfunction in this network can cause hyper/hypo sensitivity, in addition to problems with coordination, behavior and academic issues.

Evidence from brain imaging studies has also shown that autists experience stronger responses in the brain to sensory stimuli in areas that process sensory information and the amygdala- an area that is involved in attention, emotional reactions and threat response.

But why is this?

Several studies have found evidence of hyper-excitability and hyper-connectivity in the autistic brain.

Evidence shows that in many cases of autism, the neurons located in the sensory cortex of the brain are more sensitive and excitable than others. This is kind of like how a person can be more ticklish in some parts of the body than another- the nerves in the underarm are more excitable than those of the arm.

The autistic brain has also shown signs of hyper-connectivity, where regions of the brain are excessively connected- like an overloaded plug!

This amplifies memory formation, sensory processing and causes an autist to be hyper-emotional, which can make the world painfully intense. Scientists have theorized that autists prefer safe, controlled and predictable environments as a coping mechanism to actively avoid this pain.

Finally, studies have indicated that sensory issues, in addition to a number of other autistic behaviors, may be linked to neurotransmitter (chemical messengers between body and brain) levels in the body. As previously discussed, some neurotransmitters are dysregulated in autism. Evidence suggests that in cases of autism, there are higher levels of excitatory neurotransmitters, and lower levels of inhibitory (i.e. calming) neurotransmitters. These high levels of excitatory neurotransmitters cause neurons to fire excessively, which can influence sensory perception and processing.

I’ll expand a little bit more on the individual sensory issues at a later stage 🙂

Enjoy your week everyone 🙂

Autism 101- Savantism & High IQ’s

Greetings Earthlings! 🙂

Following on from the previous post examining ‘Rain Man‘, today I’m going to dive into the area of high IQ’s and savantism relating to autism.

Now before we start, remember- in spite of what Hollywood has led us to believe, savantism is a RARE condition affecting between 0.5 and 10% of autists. This means that over 90% of the autistic community do not possess these skills.

So be sure to take ‘Rain Man‘ with a grain of salt.

Now that we’ve got that out of the way, let’s explore this fascinating condition properly 🙂

So first off- what exactly is savantism?

Savant syndrome is an extraordinary phenomenon wherein a person with serious mental disabilities (such as autism) shows unusual or exceptional aptitude for a particular area, task or activity in spite of their mental challenges. Historically, these individuals were also referred to as ‘idiot savants’, a term that is sometimes still used today.

While seemingly insensitive, the phrase actually comes from the French term meaning unlearned (idiot) skill (savant).

Surprisingly, savant skills tend to exist within five different skill categories:

Music (perfect pitch, performance skills)
Art (drawing, painting etc.)
Mathematics (human calculator abilities)
Calendar calculating (i.e. can tell you the weekday a previous date fell on)
Mechanical/Spatial skills (model construction, mental measurement calculation)

Other skills have been recorded, but most generally fall within these categories.

Like autism, savant syndrome exists on a spectrum with varying degrees of savant ability. For example, there are:

Splinter skills- the most common form, involving memorization and obsession with facts, music, trivia, licence plate numbers etc.; kind of like specialist interests
Talented savants- who show highly honed talents and abilities predominantly in single areas of expertise
Prodigious savants-those who possess extraordinary skills

Savant skills are additionally accompanied by exceptional memory. For example the ‘megasavant’ Kim Peek on whom ‘Rain Man‘ is based, memorized over 6000 books in his lifetime, all US area and Zip codes, several maps and possessed encyclopedic knowledge of music, geography, literature, history and sports to name but a few!!!

Astonishing!!! 😀

So what’s going on in the brain to cause this?

Numerous theories have been proposed to explain this phenomenon, but as with autism, there is no one single theory to explain all cases. However, two theories in particular seem to dominate.

As savantism is found more often in cases of autism than in other mentally disabled groups, leading expert Simon Baron-Cohen proposed a theory concerning hyper-systemizing.

I know- it sounds complicated! 😛

But basically the theory suggests that savantism results from an autists ability to recognize repeating patterns (systemizing) and excellent attention to detail. People with autism have a different style of thinking and memory filing and this predisposes them to savant skills 🙂

Further to this another theory, supported by several neurological studies of savants, indicates that dysfunction in the analytical left hemisphere of the brain (responsible for logic, language, reasoning, maths etc) causes the right hemisphere (creativity, imagination, art, music) to compensate, which can cause savant skills to emerge. It’s kind of like the right hemisphere is giving the left a piggyback.

In addition to savantism, higher IQ’s are sometimes linked to autism and Asperger’s syndrome.

A number of studies have found that some of the genes linked to autism development are also associated with high intelligence. The link between autism and intelligence is not yet clear, however, people who carry these genes scored better than those without on intelligence tests.

These findings create an interesting paradox given that autism is generally characterized by lower IQ’s. Researchers have proposed the hypothesis that autism involves augmented, but imbalanced elements of intelligence to counter this paradox. This basically means that autists have higher levels of intelligence in some areas (e.g. academia, mathematics, art etc.) but not in others (e.g. social intelligence).

So there we have it, just a quick over view of savantism and IQ in autism! 🙂

Enjoy the weekend everyone! 🙂

Autism 101- Digestive Problems

Greetings Earthlings! 🙂

Today I’m going to discuss the issue of digestive problems for people on the spectrum- but don’t worry, I’ll stick to the science! I won’t regale you with any personal tales on this occasion 😛 😉

Gastrointestinal (GI) problems are among the most commonly associated conditions with autism.

giphy (18).gif

Evidence suggests that autists may be over 3.5 times more likely to suffer from issues such as diarrhea, constipation, food allergies, gastroesophageal reflux disease (GERD), irritable bowel syndrome (IBS) and inflammatory bowel diseases (i.e. Crohn’s disease and ulcerative colitis).

I know- not the most pleasant of subjects, but we can all be adults right? 😉

giphy (19).gif

Joking aside- these are serious issues for people with autism, especially for children. Autists are already sensitive to such stimuli as sound and touch. Adding GI discomfort to the mix can make things so much more difficult. The associated pain from these conditions can worsen behaviors, and in some cases, trigger regressions.

So what does science have to say about all of this?

As with autism, it’s another game of Cluedo- research is ongoing to determine ‘who-dunnit’. There are many suspects, but the culprit remains unclear.

Bacterial Abnormalities & Carbohydrate Digestion-The gut is home to trillions of bacteria naturally living in harmony with us. Our gut provides them with food and shelter, and in return they digest certain dietary substances and produce vitamins B and K for us to absorb. This forms what is known as the gut microbiome. Ordinarily bacteria and host exist in harmony, however, if there is an overabundance of certain bacterial strains, this can lead to a number of GI problems. Studies have shown that such overabundance exists in children with autism.

Abnormalities in carbohydrate digestion have also been reported in cases of autism. The cells of the intestines appear to have difficulty in breaking down and transporting carbohydrates in the gut causing malabsorption of these vital nutrients.

It’s been suggested that these issues with carbohydrates may be connected to the high level of bacteria present in the autistic gut as digestive alterations may influence nutrient availability within the microbiome, but further investigation is needed.

Furthermore, in recent years, evidence is emerging that gut microbes can influence brain development and behavior!

Wuttttttt???!!!

I know!!!

In particular, there is evidence to suggest that people with autism are missing one specific bacterium- Lactobacillus reuteri.

One study in mice showed that following the addition of this bacterial strain to their diet, the natural microbiome of the was gut restored AND further restored some behaviors associated with ASD’s! Interestingly, L. reuteri promotes the production of oxytocin, which as previously discussed, is essential for human bonding and social behavior.

Who knew that bacteria could control our brains this way?!

Brain-Gut Communication and the Role of Serotonin-As in the picture below, the brain and the gut share a very close relationship in the human body.

The gut in actual fact has it’s own complex nervous system (the enteric nervous system) which regulates the activity of the gut- kind of like a second brain. Together, the gut and the brain form what is known as the brain-gut axis, a two way street where each can influence the other. For example, signals travelling from gut to brain can influence satiety, whereas stress/anxiety signals from the brain to the gut affect gut sensitivity.

Serotonin is an important neurotransmitter (chemical messengers that allow neurons to communicate) within this axis. For example, serotonin plays an important role in the control of intestinal motility. As such, alterations in serotonin levels have been implicated in a number of GI problems.

But how does this relate to autism?

Yep- you guessed it, serotonin levels, like oxytocin, are dysregulated in autism, and therefore likely contribute to associated GI issues.

Further to this, there is also evidence to suggest that certain gut bacteria are involved in the production of serotonin in the body by interacting with serotonin producing cells (enterochromaffin cells). So perhaps alterations in these serotonin producing bacterial colonies may also contribute to these GI issues.

Diet-As people with autism often have restrictive eating habits, it was proposed that perhaps diet may contribute to GI issues. However, studies have shown that although autistic diets may differ, overall nutritional intake does not. On the other hand, many people report improvements in both GI and autistic symptoms following gluten (a protein found in grains like wheat) and casein (a protein found in dairy) free diets, but there is insufficient scientific evidence to support this.

Genetics- Finally, scientists believe that as with autism, genetic abnormalities likely contribute to these GI issues. Moreover, as autism and GI problems are so frequently linked, researchers have suggested that perhaps they both share the same underlying genetic mutation or may be caused by some other unknown biological mechanism.

So there we have it! 🙂

Hope you enjoyed this ‘alimentary’ introduction to digestive issues and the spectrum! 😉

Autism 101-Lesser known ASD’s

Greetings Earthlings! 🙂

Today’s post is going to be short and sweet exploring two of the lesser known ASD’s:

Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS)
Childhood disintegrative disorder (or Heller’s syndrome)

I know… these are a bit of a mouthful, but once you get past the names they’re not that difficult to understand 🙂

Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS):

As discussed in my Intro to the Spectrum, a pervasive developmental disorder impairs normal growth and development of the brain resulting in a wide range of effects (i.e. autism). PDD-NOS is basically a catch all term to describe individuals who are on the spectrum, but do not fit the criteria for specific ASD’s.

So if you had some of the traits of Asperger’s syndrome for example, but didn’t fully fit the bill, you may be given a diagnosis of PDD-NOS.

This is often referred to as atypical autism.

Childhood disintegrative disorder/Heller’s syndrome:

Childhood disintegrative disorder (CDD) is a rare ASD, estimated to be 60 times less prevalent than classic autism. In comparison to other ASD’s, this low functioning form of autism is quite unusual in it’s late onset.

Children with CDD appear to develop normally before suddenly showing signs of developmental delay around 3-4 years of age. In some cases, there are even reversals in development with loss of speech, motor skills and social function- as if someone hit the rewind button in your brain.

giphy (7).gif

This is known as regressive autism.

Discovered 35 years prior to autism, to this day, doctors remain baffled as to the cause of this condition.

So there we have it- not quite as complicated as the names suggest 😉

As this is a little more clinical than some of my other posts, I’d like to end on an encouraging note.

Last year, some of you may have come across this viral interview with actor Channing Tatum:

In the video, Channing is interviewed by Carly Fleischmann- a remarkable young woman with non-verbal autism. As a child, Carly was diagnosed with autism, cognitive delay and oral-motor apraxia (the inability to properly coordinate oral movements for speech). At first, such a diagnosis appears devastating, but in this video, Carly proves an ASD diagnosis is not the end of the world.

Through years of persistent therapy and hard work, Carly found ways to communicate by typing with one finger. Although still confronted with the serious challenges of autism, in this video, Carly achieves her dream of becoming the world’s first autistic, non-verbal chat show host! 😀

giphy (10).gif
When a diagnosis of autism is given, it can be difficult to remain positive. Unlike Dante in Inferno however, we need not abandon hope.

It very much exists.

Whatever your spectrum diagnosis may be, Carly’s story shows that we can succeed in spite of our difficulties 🙂

Autism 101- Specialist Interests

Greetings Earthlings! 🙂

Today I’m going to expand on the topic of specialist interests (SI’s).

SI’s are one of the defining features of Asperger’s syndrome in particular. Hans Asperger originally described us as ‘little professors‘ due to our ability to talk about our interests in great detail- often droning on in lengthy lectures, completely oblivious to our bored audience….

….so I’ll try my best not to bore you today 😛 😉

As discussed in the previous post, specialist interests are subjects which autists are intensely preoccupied with. These are generally associated with higher functioning forms of autism, but have also been noted in lower forms. Interests can be random items (e.g toilet brushes and deep fat fryers- I have genuinely come across these examples in a research paper!), subjects that are unusual to focus so intently on (dinosaurs, trains, Star Trek etc.) and finally topics that overlap with the hobbies of normally developing peers (horses, music, gaming etc.).

Women in particular tend to have SI’s akin to those of their peers, which can make it harder to diagnose them.

This would have been my experience of SI’s. My most intense interest growing up was that of Harry Potter. It would have been seen as perfectly normal to be ‘potty about Potter’ as a teenage girl during the noughties, but few would have shared my intensity.

This intensity is the major difference between normal ‘fandom’ and SI.

Unlike fandom, your interest can entirely consume you. It’s like an addiction- you are hooked on your interest. It’s not a case of want, but you physically HAVE to get your fix. If you don’t get it, your brain feels like it’s going to explode.

If I didn’t get to see the latest Harry Potter film at the first possible showing, it literally felt like the end of the world. I once made a phone call to my mother after seeing gameplay footage for Harry Potter and the Chamber of Secrets to say that I needed the game NOW (why Aoife!)…even though I knew it was under the tree for Christmas!

But I just HAD to have it in that moment!

Oh but when I got that game- what a feeling!! Even better when I got to experience TWO different versions of the game on both PC and PS2!!!

Talk about shooting up on dopamine! 😀

It’s a little difficult to explain the feeling in words. It’s not just a sense of happiness or excitement, it’s like the atomic bomb version of Beatlemania has gone off in my head- if that makes sense?

Let me try to explain the feeling with gifs, I think these sum it up better:

If you combine all of these at once- that’s what it’s like in my brain.

Kind of a miracle that it hasn’t full on exploded yet 😛

Your interest is more than just obsession- it’s compulsion. Every time that I saw a still from the Harry Potter films in a newspaper or magazine, I was compelled to cut them out to add to my collection. It didn’t matter that I had the same picture six times already, I had to have it! If I didn’t get it, I would genuinely torture myself about that one lost picture, or missed TV special for years afterwards! Even now the residual memory of those missed moments still bother me! 😛

As with all addictions however, you can take things a little too far to get your hit…

One of the most memorable examples of this was my dedication to reading the latest Harry Potter books. Determined to be the first to finish the book, I would read in the car! This doesn’t sound too extreme at first….however, I can get motion sick from looking down while travelling in the car… but I didn’t care!

I read until I threw up and then read some more!!

In addition to this, I was also caught sneaking into my mothers room in the dead of night to nab the Half Blood Prince from her after the midnight opening! 😛 Luckily, we had the sense to buy two copies for the Deathly Hallows midnight release 😉

Such are the lengths we are willing to go to for our specialist interests. You become so intensely focused that you are often blinded as to the lows to which you sink…

penny-needs-help-for-her-computer-addiction-on-the-big-bang-theory

In addition to subjects, people can often become SI’s- especially in women. I’ve definitely been guilty of this at times.

You connect with a person, and like other areas of interest, you want to know everything about them- even the things that are socially unacceptable to ask! When you spend time with that person, it’s never enough. If you see them hanging out with other friends on social media, you feel a pang of regret/jealousy that you weren’t there- as genuinely irrational as you know your feelings to be. I suppose it’s like any other interest, every missed moment with your friend feels like a missed concert for your favorite band- a one off event that can never be recaptured.

You know you’re obsessing and that you shouldn’t feel like this, but you just can’t seem to stop yourself.

Even worse when you inadvertently cling on so tightly that you end up smothering your SI…We don’t mean to act like crazy people, but sometimes it happens.

Word of advice to human SI’s: Just wait it out. We’ll move on to our next interest before long. Just try to understand and love your friend as they are 🙂

So why are we so inclined towards these interests?

Scientists are of the opinion that SI’s reflect some of the heightened abilities unique to autism such as systemizing- the drive to explore, analyze or construct a system. SI’s are also thought to correlate to the severity of social impairment in individuals with autism, serving a role in reducing stress and anxiety.

For me personally, I find that SI’s provide a source of comfort. Life can be pretty overwhelming for people with autism, and sometimes we need to escape. In my own life I have found that some of my more intense interests were born of the flames of turbulent times.

When I was 11, we sold my childhood home and I was completely knocked out of sync. This simple change combined with the joyous trials of puberty had a devastating effect on me. My world was, to my mind, spinning out of control, and I wasn’t coping very well. Around the same time, the Hogwarts Express was just leaving the station, and I jumped on board to escape. The books, the films and the games transported me to another world away from all of my problems. Harry Potter gave me a sense of control, an oar to navigate the rapids of life- which is kind of ironic given the intense hold that SI’s can have over us! 😛

For any parents out there reading this, don’t worry too much about our SI’s. This is perfectly normal behavior! 🙂 And if you’re sick of hearing about your child’s subject- they’ll move on eventually 😉

Top Tip- Experts in the area recommend using SI’s to encourage your child in other areas they may struggle with. I really struggled to study for my exams when I was a teenager, so my mother encouraged me through an SI- gaming. For every hour of study I managed, I was awarded with an equal amount of gaming time. Before long, I was studying without any incentive at all!! 🙂

Have a good weekend everyone! 🙂

Autism 101- Asperger’s Syndrome

Greetings Earthlings! 🙂

In continuation from my previous post, I’d like to introduce you properly to Asperger’s syndrome or AS. More and more frequently are we hearing of the condition, but very rarely is it explained to us. I myself knew relatively little about the disorder upon diagnosis, and that was with a degree in physiology!

So what exactly is Asperger’s syndrome?

Asperger’s syndrome is a form of high-functioning autism. As with all ASD’s, the normal development of the brain is impaired in AS, however, the symptoms are considered less severe. For example, the social communication difficulties experienced by those with AS are much milder than other ASD’s. We may struggle to communicate our intentions, to empathize or to make eye contact, but much of this can be learned and improved with time 🙂

Unlike classic autism, individuals with AS show relatively normal intelligence and language skills. AS is in fact often associated with higher IQ’s, and in some cases savant skills (mathematical genius, eidetic memory, musical/artistic genius etc.).

Stereotype alert!!!- The majority of Hollywood portrayals of autistic individuals depict us as having savant skills. This is a RARE condition affecting between 0.5 and 10% of autists. (So no- I can’t count cards in Vegas with you like ‘Rain Man‘ 😛 ).

Motor development can also be affected in AS. In comparison to my peers, it took me a lot longer to hit some of my finer motor milestones (nearly 3 years to master shoelaces for example). Additionally, people with AS are often quite clumsy- something that I may know a thing or two about…

It’s gotten to the stage where I fall down the stairs so often that my family rarely come to my rescue (I’ve learned to fall with style sustaining minimal injury)! I’m also quite adept at falling over my own feet…the worst fall of my life came after tripping myself up, and not letting go of the Alsatian I was holding…

…at least we were still in the driveway! 😛

Unusual use of language is also associated with AS. This doesn’t mean that we create our own language or anything weird, but that we have a tendency towards unusual turns of phrase.

I, for example, am particularly fond of using big words- ruminate, cornucopia and ethereal are particular favorites! In my head I can’t see why you wouldn’t use a fancy word like ephemeral or fleeting instead of temporary! 😉 Although this did get me into trouble once with my supervisor for using the word ‘multitudinous’ in a research paper…

Restrictive and repetitive behaviors (like OCD) are additionally found in cases of AS.

These can manifest in a number of ways. There is a tendency towards routine in AS for example- we don’t like change and the uncertainty it brings. In a world that doesn’t always make sense, routine offers stability and control.

One of the most striking features of AS is our tendency towards having a specialist interest. These are intense areas of interest in which we accumulate mountains of information about a single molehill! If you stumble upon one of my interests in conversation, advanced warning- you could be there a while! 😛 😉 I’ll write a separate post discussing specialist interests in detail on Friday 🙂

So there you have it- a quick overview of Asperger’s syndrome! 🙂

These are just some of the typical characteristics associated with AS. If I were to fully explore the symptoms today, this post would likely be the length of a book! But I’ll do my best to break everything down for you as I go along 🙂

Autism 101- Intro to the Spectrum

Greetings Earthlings! 🙂

Apologies to anyone who got an email yesterday- my computer had a moment and hit publish with only two lines written! 😛

Today I’m going to discuss some of the basics of autism to better acquaint you with the condition. As a scientist, I’ve read my fair share of research papers on the subject…

…so I’ll try my best to break it down! 🙂

Autism is defined as a pervasive neruodevelopmental disorder.

“What on earth is that?!”

This simply means that autism is a disorder that impairs the normal growth and development of the brain resulting in a wide range of effects throughout the body.

Simple enough 🙂

Autism is thought to impair the development of the brain in areas associated with social interaction and communication, however, some studies suggest that the disorder may in fact affect the entire brain.

So how do these impairments manifest?

Typically, people with autism show deficits in three main areas:

Social communication
Social interaction
Social imagination (this basically means that we struggle to predict the reactions of others, understand abstract ideas, imagine situations outside of daily routine etc).

These are known as the ‘triad of impairments’. There is also a fourth area of impairment describing struggles with sensory processing (touch, sound, light etc.), but ‘tetrad’ doesn’t quite have the same ring to it!

Each autistic person has their own unique blend of symptoms ranging from mild to severe (there’s FAR too many to detail in this post alone). No two individuals with autism are the same.

Forget about the stereotypes- if you’ve met one, you’ve met only one.

Here’s a little schematic I threw together showing how symptoms can vary using academic ability as an example:

Such variations led to the catch-all concept of the autistic spectrum.

Everyone exhibits some autistic traits (my friends have remarked that the more traits I describe the more they think they have autism! 😛 ), but it is when you exhibit a high number of these traits that you are diagnosed with an autism spectrum disorder (ASD). For example, the average person scores ~15-17 out of 50 on the autism-spectrum quotient test, whereas the average autist scores 35 (I scored 38…!).

There are currently four separate ASD’s listed on the spectrum– Asperger’s syndrome (yours truly!), autistic disorder, childhood disintegrative disorder and pervasive developmental disorder not otherwise specified (PDD-NOS). I’ll write separate posts about these in due course 🙂

So what actually causes autism?

In truth- we don’t know for sure!

Most evidence points to a genetic cause as autism can be hereditary, but there has been no one autism gene isolated. As autism operates on a spectrum, it’s likely that there are numerous factors at play in each ASD. The current thinking is that lot’s of smaller gene mutations combine to cause autism. Like the X-men launching an attack! 😉

As interesting as the science of autism is however, it can’t really explain the experience.

The easiest way to explain it I find, is to consider Supergirl.

Supergirl is an alien from the fictional planet Krypton. The elder cousin of Superman, she arrives on Earth as a teenager, a stranger in a strange land. She looks like a human, talks like human and for the most part acts human, but Supergirl does not see the world as a human does; she perceives the world as a Kryptonian. When she first arrived on Earth, Supergirl had to learn to blend in. She would have struggled to learn our customs, sayings and social ways, all the while concealing her true alien self lest she be ostracized, just as I’ve had to do.

That’s what autism feels like- being an alien from another planet. What’s normal for you seems weird to the rest of the world. Social rules confuse you, you interpret things differently and find yourself spending much of your time hiding your quirks from sight.

As I’ve discussed in previous posts however, the autistic experience, while different, is not necessarily bad. With different perspectives and brain chemistry come different abilities. Like Supergirl, many of us have unique gifts and talents to share.

I can’t say that I have laser eyes or the ability to fly like her, but I am pretty handy with a set of knitting needles creating patterns off the top of my head! 🙂 Knitting was a struggle for me at first- I was the WORST in my class for years, but one day it just clicked! Something I was once terrible at could now be considered a superpower of sorts!

sgsd

This is one thing that I’d like to emphasize in these blogs- struggle. You’ll find that I will never use the word ‘can’t’ in relation to autism.

In these posts, I want to highlight that yes, autism is a struggle- life can be bloody hard at times; but just because we struggle, does not mean that we are not capable, or that we should be treated as such.

I have struggled with many things in life- learning to drive, knit, dance, tying my shoelaces etc.Yes, indeed I struggled, but that didn’t mean I wasn’t capable, it just took me a little bit longer. Like Supergirl, the struggle passes and you learn to adapt.

The hardware in our brains may be a little different, but with software updates, patches and a little patience, we can learn to function as well as any other computer 🙂
