Autism and Sensory Socks

Greetings Earthlings! 🙂

This week I’d like to discuss a rather unusual item that can be used for management of autism- the sensory sock! Here’s a picture of what it looks like:

So what exactly is it?

The sensory sock (also known as the body sock) is a stretchy Lycra suit of sorts that is designed to provide a unique, fun and intense sensory experience for autists. Once inside, the suit provides tactile and deep pressure stimulation to the wearer while increasing spatial awareness and improving balance. These sensory inputs can be quite calming for autists which can help us to regulate sensory issues. This can also be used for neurotypical kids to explore their environment and encourage creative movement.

But how exactly does it work?

The stretchy Lycra provides resistance to the wearer as they move around applying deep pressure to the joints which, as previously explained in my post about weighted blankets, causes the release of calming neurotransmitters in the brain, reducing the levels of excitatory neurotransmitters which are elevated in the autistic brain. The enclosed space can help the wearer feel calm and safe, allowing them to regulate their emotions- many autists find enclosed spaces to be particularly therapeutic, so having a portable space like this can be really handy!

I came across the video below of someone trying out a sensory sock online, so naturally I had to get one to try it out!

So how did I get on?

Well…it was…an experience! 😛 While I won’t terrify you with the images of me waddling around my kitchen like a deformed bright green T-Rex, the sock was certainly worth the laugh! My first impressions however, were not the most positive from a sensory perspective. I didn’t really like the smell or the feeling of my arms being so constricted, and found the velcro opening at the front quite distracting as it was reluctant to stay shut (sensory socks don’t seem to be designed for adult women of a certain chest size 🙈). I did try the sock again a week later, but this time I chose to lie down while wearing it which proved to be a much more positive experience. This time I felt the relaxing deep pressure around my limbs that was reminiscent of my weighted blanket. Despite my best efforts, I wasn’t able to bring myself to spend more than a couple of seconds with my head inside the suit. It either wouldn’t stay closed or the smell and claustrophobia got to me so I wasn’t really able to assess that feature.

All in all, I can certainly see the benefits this sensory sock might have for younger autists, but personally I think I’ll stick with my weighted blanket for now.

Hope you enjoyed this post dear Earthlings!

Have a lovely weekend! 🙂

Autism and Clothing

Greetings Earthlings! 🙂

This week I’d like to briefly expand on something that I touched on in my previous post about skin sensitivity, -the importance of clothing and autism.

bitmoji-20190401080206

No, I’m not going to talk about fashion, but function!

For many autists, it can be quite difficult to pick out clothes. A stray fiber, an itchy label or a prickly seam can unleash a storm of sensory discomfort. Gene mutations cause the nerves in our skin to be extra sensitive to certain stimuli. This coupled with hyperactivity in the cortex and the amygdala (both regions involved in sensory processing) don’t make for the happiest of bedfellows.

But what if the clothes that irritate us could in fact be used to manage autistic symptoms?

bitmoji431833082

Clothes are now being designed and adapted to cater for the different needs of autists. Companies are now producing seamless socks and underwear, looser fitting clothes made from softer materials, and most interestingly, weighted and compression clothing.

Based on the research of the great Temple Grandin and her hugging machine, both weighted and compression clothing provide calming, deep pressure stimulation much like a soothing hug. The pressure switches off the sympathetic nervous system (fight or flight) to the parasympathetic nervous system (rest and digest), promoting the release of “feel good” neurotransmitters. Based on this, it’s thought that autists are better able to cope with sensory issues, hyperactivity, motor skills and sleeplessness when wearing sensory clothing.

It’s a really interesting premise- there’s even been an inflatable sensory scarf produced that’s designed to provide soothing pressure in addition to emitting calming aromas! Check it out:

https://www.wired.com/2015/08/odd-looking-clothing-designed-help-autistic-kids/

In reality however, the results are mixed. Scientific studies indicate that weighted and inflatable vests do not appear to be effective and are not clinically recommended, yet the personal testimonials of families across the globe beg to differ. One testimonial claimed that a child’s meltdowns went from 12 a day to having none in 3 years!

Either way, nothing ventured nothing gained, so if you think that sensory wear may be of benefit to you or a loved one with autism, why not give it a shot? 🙂

With the variety of sensory wear available, you’ll at the very least look fabulous! 😉

Autism and Mental Health

Greetings Earthlings! 🙂

Did you know– autistic children have higher levels of depressive symptoms and are 28 times more likely to have thoughts of suicide than their neurotypical counterparts? 😲

bitmoji1256098968 In recent years our awareness of and willingness to tackle mental health issues has increased significantly, however, the autistic community is often forgotten in our discussions.

Mental health issues such as OCD, anxiety, depression, eating disorders, ADD, psychosis, personality disorders and bipolar disorder are frequently co-morbid with ASD diagnoses, but aside from OCD and anxiety, you will rarely hear about these other issues in relation to autism. In fact, such mental health issues can even obscure ASD diagnoses in higher functioning autists as clinicians often diagnose the co-morbid condition without seeing the underlying ASD.

This is a particularly big issue for women on the spectrum as experts have found that we tend to exhibit greater depressive symptoms and higher anxiety levels than our male counterparts as we tend to internalize and ‘mask‘ our struggles. Moreover due to differences between male and female presentation of ASD’s and male bias in the development of the diagnostic criteria, women with autism are often misdiagnosed as having mental health issues, but the root ASD continues to evade.

bitmoji-20190226102522

But are there any scientific reasons why mental health issues are so prevalent among autists?

A recently published study has suggested that perhaps the gut may influence an autists mental health. As gastrointestinal issues are often co-morbid with an ASD diagnosis, and as the microbes that live in the gut can have an influence on the brain and behaviours, it has been proposed that perhaps a “dysbiosis” or imbalance in gut microbes may have an influence on an autists mental health 😲

Interestingly studies have also identified an overlap between the genes that cause schizophrenia, bipolar disorder and autism wherein certain points on these genes encode proteins that are involved in the formation and strength of synapses (which act as chemical bridges between neurons) suggesting that these disorders may act through a similar neurological pathway. Moreover, dysregulation of neurotransmitters (biochemical messengers in the brain) has also been implicated in depression, anxiety, bipolar disorder, ADHD and autism (as we have discussed in multiple previous posts) indicating further neurological overlaps.

In short, it seems that the biological basis of both autism and mental health issues are intertwined, which could explain why so often the two walk hand in hand.

Autism and Pain

Greetings Earthlings! 🙂

As I am currently recovering from the removal of my wisdom teeth (contrary to popular belief- my mouth is too small 😛 ), I’ve decided to write about pain and autism this week.

Image result for pain gif

One might imagine that autists have a higher response to physical pain owing to our sensory sensitivities, however, pain perception, as with all aspects of the spectrum, is entirely individual to the autist.

Some are hypersensitive (touching the skin or simply brushing your hair can cause pain), whereas others may in fact have very high pain thresholds. Yours truly unknowingly lived with a permanent ulcer in their mouth from an impacted wisdom tooth for a couple of years due this without batting an eyelid! I thought that was how it was supposed to look…😂😬!

So why the polar responses to pain?

The evidence as to why this is is unclear. For many years, researchers believed that people with autism were insensitive to pain as they did not always respond to pain in the usual manner (crying, seeking comfort etc), in addition to the display of self injurious behaviours. However, more recent studies have challenged this notion indicating that people with autism show signs of hypersensitivity to pain in the brain, experiencing greater physiological responses to pain than neurotypical peers.

The autistic brain clearly demonstrates alterations in “normal” pain pathways, but is there a root explanation?

Some evidence points to genetic mutations in such genes as the Shank genes (which have recently been implicated in a number of autistic behaviours), however, the explanation could be much simpler. As discussed in previous posts, numerous neurotransmitters are dysregulated in autism- neurotransmitters which play an important role in our perception of pain.

Evidence suggests that Dopamine in particular plays an important role in the modulation of pain perception and analgesia in the body. Many studies have linked dopamine dysregulation to autism, which could explain why pain responses vary among autists 🙂

There we have it now Earthlings! 🙂 Hope this post wasn’t too “painful” for you! 😉

Okaaaay, that was a bad one! Sorry 😛

We’ll blame that pun on my wisdom teeth! 😉

Autism 101- ADHD

Greetings Earthlings! 🙂

So today I’m going to be talking a little bit about-

Haha! Sorry about that! 😛 Although fun story- genuinely stopped mid conversation to cry “SQUIRREL” when out with a friend recently! 😉

Yes that’s right, today we’ll be talking about ADHD in autism- also known as attention deficit hyperactivity disorder.

ADHD is commonly diagnosed in autists (in the region of 29-83%), causing such difficulties as impulsiveness, over-activity and poor attention.

There are 3 main types of ADHD:

Inattentive ADHD (formerly known as ADD (attention deficit disorder))- This can manifest in a number of ways such as a lack of attention to detail, losing things, organizational problems, making careless mistakes, having trouble completing tasks and struggling to sustain attention.
Hyperactive-Impulsive ADHD- Signs of hyperactivity and impulsivity include restlessness, excessive talking (Guilty!) fidgeting, interupting others, impulsive descisions and activities etc.
Combined Inattentive and Hyperactive-Impulsive ADHD

Personally, I would have really mild combined ADHD tendencies. In addition to my sometimes impulsive nature, I have a habit of zoning out of lessons and conversations, sometimes even films, books and TV shows for brief moments, completely lost in my own thoughts.

I can be pretty easily bored and distracted!

Half the time I’m not even aware of it happening. I could be reading a page in a book one minute, and suddenly find myself halfway down the next page, without any idea of what I was supposed to have taken in! Other times I find myself in a room in the house unsure as to why I came in as I hopped onto another train of thought mid action! I often have to repeat tasks over and over in my mind to ensure I don’t forget them.

My mind just completely wanders off…

But somehow I’ve always managed to hide my inattention. It never really posed a problem at school. Teachers knew I was away with the fairies, but could never seem to catch me out when pressed! 😛 I suppose my deductive skills must have learned to compensate for my temporary lapses in concentration! 😉

Top Tip: Studies have suggested that playing video games may be beneficial to improving concentration in ADHD.

Just because concentration can be a struggle however, does not mean that you can’t concentrate.

Interestingly, there occurs a concentration paradox in ADHD and autism known as hyperfocus- an intense form of concentration where you are completely absorbed by a task, something that I like to call “The Zone”. I’ll write a separate post on hyperfocus at a later stage 🙂

Aoife’s Top Tip: Applying specialist interests to tasks can encourage concentration. Last year I was struggling to write an essay for college, I found an angle that allowed me to write about Eurovision and suddenly I couldn’t stop writing! 🙂

In addition to my lapses in focus, I can also be a little bit hyperactive. Now, hyperactive doesn’t necessarily mean bouncing off the walls like a child high on sweets, it can also mean abnormally active.

I am quite a restless individual. On the outside, I may look like I’m staring at a wall, in my mind I could be designing a cake, a knitting project, writing a story or drafting a hypothesis. I once spent a train ride visualizing, staging and arranging a musical based on the music of My Chemical Romance!😂

I always have this need to be productive, even if it’s as simple as building my trophy collection on the Playstation or binge watching a TV series.

My brain never turns off!

If I’m excited enough, I do bounce around the place on occasion too 😉

But what’s going on in the brain that interrupts our concentration?

It is not clear what exactly causes ADHD in the brain, but remember neurotransmitters? (Inside the Autistic Brain, Autism 101-Sensory Processing, Autism 101- Digestive Problems)

Most current models point to low levels of the neurotransmitters Dopamine and Noradrenaline. Pathways involving these chemical messengers project to the striatum and prefontal cortex of the brain- areas which are responsible for executive function (i.e. memory, planning, organization, behaviour control etc.). If these neurotransmitters are out of sync, this will have an effect on these functions. As neurotransmitters are also dysregulated in the autistic brain, this would explain why ADHD so commonly occurs in autism.

ADHD, like autism, can’t be cured, but it can be treated with cognitive behavioural therapy (CBT) and medication in severe cases, however, the side effects of medical treatment for ADHD have been controversial, and long term usage studies have yet to be completed.

However, like autism, ADHD need not hold you back in life. Some of the most successful people in the world have ADHD, such as Sir Richard Branson, Justin Timberlake, Simone Biles, will.i.am, Russell Brand, Ryan Higa, Jamie Oliver, Jim Carrey and Solange Knowles 🙂

So to conclude Earthlings-

Wait! What was I saying again?! 😉

Have a good weekend guys!! 😀

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! 😛

Image result for hit in face with ball gif

^^^^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! 🙂

Social Awkwardness & Autism

Greetings Earthlings! 🙂

Soooo today we’re going to talk about perhaps one of the biggest banes of my life- social awkwardness! 😛

I’m not going to lie- social awkwardness is not fun. The constant fear of saying the wrong thing or not knowing what to say, the burning sensation in your face that’s never far away (huzzah for unintentional rhyming! 😀 ).

This article sums up the feeling pretty nicely through gifs’ s:

http://mashable.com/2013/08/15/awkward-gifs/#N36QeeXevGqn

Sitting awkwardly by yourself waiting for friends to arrive in a pub, tapping your glass and constantly sipping just to look like you belong, the pitying glances of bar staff when they see you at a table alone-the awkwardness can be all consuming.

I can’t tell you how many times I’ve wanted to run from/avoid social encounters because of this awkward feeling.

Awkwardness is worse still when you’re hit by memories of previous awkward encounters! It’s a real domino effect- one awkward memory brings dozens more to the surface until you’re drowning in the red hot embarrassment of a cringe attack! 😛

I am constantly haunted by memories of my social awkwardness, buuuut as time goes on, you eventually learn not to dwell on your social failings 🙂

It’s a struggle yes, but you can push through the awkwardness. Over the years I’ve devised ways to navigate the rapids- making self deprecating jokes, keeping a mental list of backup topics for awkward silences, chugging a drink you’ve been bought (but don’t like) while your friend is in the bathroom so they don’t see your disgusted facial expressions 😛 😉

Social awkwardness may be a pain, but ultimately you can’t let the fear of getting wet keep you from swimming the social seas 🙂

Who knows-you might even put your awkward stories to good use in a blog some day! Comedy is tragedy plus time after all! 😛 😉

But is there any scientific reason for our social awkwardness?

Remember oxytocin?

Scientists have linked gene variations in the oxytocin receptor (which allows oxytocin to bind and interact with the body) to autism. Evidence indicates that people with autism have a specific variation in the oxytocin receptor (rs53576) which makes it more difficult for them to empathize, read facial expressions and social situations- predisposing us to social awkwardness.

In addition to this, psychologists have suggested that social awkwardness is all about perception. Awkwardness is thought to be influenced by the individuals perception of how a social situation should play out versus reality. If a social interaction does not go as planned…then the awkward turtle swims into view!

This is a particularly interesting hypothesis. Oftentimes I find myself feeling awkward when silence falls in social settings as I perceive conversational silence to be awkward….aaaand then I tend to ramble on nonsensically to fill that silence! 😛

In reality, the silence may not in actual fact be awkward. Companionable silence is perfectly natural; the awkwardness I feel may inadvertently be of my own creation!

So it seems that perhaps social awkwardness in autism comes from the disparity between perception and reality in social interaction.

Social awkwardness is also thought to ironically help people improve their social skills! It has been theorized that social awkwardness acts as a warning system to help us to recognize that we have made social mistakes so that we will not repeat them in the future.

Seeing as autists struggle with social communication and interaction, it stands to reason that we often feel awkward so that we might improve our social skills in the future.

So social awkwardness may in fact serve a purpose in autism! 😉

Enjoy the weekend 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 🙂
