Autism and Gene Mutation

Greetings Earthlings! 🙂

This week I’d like to discuss the influence of gene mutations in the development of autism.

So what exactly are gene mutations?

Gene mutations occur when the usual, expected gene structure changes to form a new gene variant that can be passed on to future generations. Mutations may include deletions (where part of the gene sequence is removed), insertions (where new information is added to the gene sequence), and rearrangements (where the gene sequence is reordered).

Autism is heavily influenced by our genes, with estimates suggesting that genetic factors contribute to as much as 40-80% of the risk of developing an ASD. Mutations in over 1000 genes have been linked to autism, but as of yet no single “autism gene” has been identified. To date, only 30% of autism cases can be explained by known gene mutations. Research has thus far explored a mere 2% of the genome for candidate genes, so there may yet be a common gene somewhere in the remaining 98%. The current thinking is that multiple small gene mutations interact to cause autism.

The following are some examples of candidate genes that have been linked to autism development:

  • ACTL6B– this gene is involved in the expression and control of many other genes in brain cells, where mutations to ACTL6B can alter these other genes to trigger autistic traits
  • Shank 3- is a leading autism candidate gene where mutations in this gene are found in 1-2% of autists. This gene expresses a protein that is essential to the proper functioning of the synapse (the junction) between neurons- a region where many autistic traits are linked to
  • PAX5- this gene encodes a factor that is important to the development of the brain during the embryonic phase of pregnancy, where mutations in the gene can lead to alterations in the brain that can contribute to neurodevelopmental disorders like autism

As interesting as genetic mutation is, it is largely considered to be a negative thing. Gene mutations are viewed as aberrant, something that many would seek to edit or correct- the entire premise of gene therapy. But while most are familiar with the concept of negative gene mutations, there are many gene mutations out there that are neutral or beneficial. For example, some people have a rare gene mutation called CCR5-delta 32 that makes you resistant to HIV infection, carriers for the gene mutation that causes sickle cell disease are resistant to malaria, and even rare mutations in the LRP5 gene can increase bone density to make your bones more resistant to breakage and age related degeneration.

In my own experience, I have a rare gene mutation that causes sectoral heterochromia- i.e. a section of my right eye is a different colour to my left eye. This mutation occurs in less than 1% of the population- made even rarer by the fact that my eyes are green (only 2% of people have green eyes). This is a neutral mutation- it’s a mutation, but not one that has any impact other than my friends find it really cool 😎

Genetic mutation is central to evolution, it’s how we grow and adapt; without it the human race would not exist. With this in mind, perhaps we need to refocus our perception of autism. We see autism genes as aberrant, but don’t consider the possibility that some of these mutations may be positive. Mutations that allow us to see the world differently, can make us think faster, have increased memory retention, give us unique creative and academic abilities etc. Perhaps a meltdown isn’t the product of a gene gone bad, but an evolved method of emotional processing (there really is great relief after a good meltdown cry- even if it isn’t the most fun in the middle of it all 😛 ).

Maybe the genes aren’t aberrant, perhaps it’s just our perception of them that we need to change.

Hope you enjoyed this post dear Earthlings!

Autism and Dyscalculia

Greetings Earthlings! 🙂

Leading on from my previous post on dyslexia, this week I’d like to discuss another lesser known learning disability that can be co-morbid with autism- dyscalculia.

So what exactly is dyscalculia?

Dyscalculia is a specific type of learning disability characterized by a difficulty with numbers and arithmetic i.e, understanding how to do maths and manipulate numbers (that’s right- not all autists are good with numbers Hollywood 😛 ) . There are varying levels of dyscalculia but signs may include difficulties with numbers and mathematical symbols, pattern recognition, sequence issues, handling money, managing and telling time, visual processing, and memory issues.

So what causes dyscalculia?

Again as with most aspects of the spectrum, the exact mechanism is unclear. Thought to be related to ADHD, dyslexia and dyspraxia, dyscalculia seems to result from dysfunction in the intraparietal sulcus (an area thought to be involved in processing symbolic and numerical information) and the frontal lobe of the brain. The frontal lobe in particular contains most of the dopamine neurons of the brain which are involved in attention, planning and short term memory- all of which are important functions in comprehending numbers. As discussed in many previous posts, dopamine levels are dysregulated in the autistic brain which could explain why autists may be more prone to these types of learning disabilities.

Is there anything that can be done to help manage it?

As with most disabilities, early detection and intervention are key to helping those with dyscalculia cope with their struggles. There have been very few targeted programs specific to dyscalculia but in recent years a number of digital programs have been created to help improve basic numerical abilities. The gold standard one to one tutoring is also a useful option to help improve these skills through repetition and targeting areas of particular difficulty. Interestingly, there was a study conducted in 2014 where electrical stimulation of the left side of the posterior parietal lobe of the brain (an area involved in spatial reasoning and planned movements) improved numerical abilities in patients. As many as 43% of autists may have abnormalities in their parietal lobe, so further research into this region could provide us with new ways to manage dyscalculia in the future.

Hope you enjoyed this post dear Earthlings!

Autism and Irlen Syndrome

Greetings Earthlings! 🙂

This week I’d like to talk about a condition that impacts approximately half of autists- Irlen syndrome.

So what exactly is Irlen syndrome?

First defined in the 1980’s, Irlen syndrome (also known as scotopic sensitivity syndrome (SSS) or Meares–Irlen syndrome) is described as a difficulty in the brain’s ability to process images/visual information. It is not exclusive to autists as it also impacts roughly 15% of the neurotypical population. As 70% of the information we process is visual, the inability to process this information can have a serious knock on effect on our brains ability to function effectively, causing issues with reading, coordination, sensory processing, spatial awareness, and ADHD– all co-morbid issues associated with autism.

But what causes it?

Irlen syndrome is caused by hypersensitivity to certain wave lengths of light which can cause the brain to process visual information incorrectly. The exact mechanism is poorly understood, but the brain seemingly becomes overactive in response to light causing dysfunction. Interestingly, Irlen syndrome is classified as a pseudo-medical diagnosis as there is skepticism over it’s existence as a stand alone condition with a distinct pathology. Experts are skeptical of Irlen syndrome as there is a lot of overlap in symptoms from other conditions and they may be lumped in under one convenient heading.

But is there anything we can do to manage symptoms?

The Irlen method is the main treatment approach for the condition. Pioneered by Helen Irlen, the Irlen method is a non-invasive approach using coloured lenses to filter light and to improve the brains ability to process visual information. The lenses can be either worn as glasses or in contact form.

You can see the impact that Irlen lenses have on the brain here:

However, the efficacy of this method has been difficult to prove. In particular there seems to be little evidence to support their use to improve reading issues and dyslexia. That being said, many people have found great relief from using Irlen lenses, such as actor Paddy Considine who has both Asperger’s syndrome and Irlen syndrome.

As with all pseudoscience/pseudomedicine, take everything with a pinch of salt, but if you think Irlen lenses may help your issues with light sensitivity it’s worth a try!

Autism and Hyperlexia

Greetings Earthlings!

Leading on from previous post about dyslexia, this week I’d like to discuss the phenomenon of hyperlexia and autism.

So first things first, what is hyperlexia?

Hyperlexia is a phenomenon where a child begins to read at a surprisingly early age beyond their expected ability compared with their peers. Onset is usually before 5 years of age, and the child tends to develop the skill without any training or prompting. It’s often described as a “splinter skill”- unique, but not very useful. It’s estimated that approximately 84% of those diagnosed with hyperlexia are on the autistic spectrum equating to between 6-14% of the overall autistic community.

There are 3 different types of hyperlexia:

  • Hyperlexia I– occurs in the neurotypical population where children learn to read at a very early age. This is usually considered temporary as their peers will eventually learn to read and catch up to hyperlexic children
  • Hyperlexia II– this is the form of hyperlexia that is most associated with autists. Beginning in infancy, hyperlexic autists are often obsessed with letters and numbers, tending to show a preference for books instead of other toys. Autistic hyperlexics also tend to have excellent recall for important numbers like phone numbers, dates and licence plates
  • Hyperlexia III– is quite similar to hyperlexia II, but the symptoms tend to decrease with time and disappear. Type III hyperlexics may have delays in verbal language and development like autists, but they tend to have remarkable skills for reading comprehension and excellent memory recall. However, unlike autists, these children generally have no issues with social interaction and anxiety

In my own experience, I’d say I probably had some mild hyperlexic tendencies as a child. I loved books- my mother couldn’t buy me enough to keep me entertained! As I’m sure I’ve told you in previous posts, my reading skills were so advanced at 6 years old in senior infants, my teacher from the previous year invited me to come and read to her junior infant class (4/5 year olds)!😂 I’ve always had an excellent memory and am pretty good at remembering dates, but as the experts say this skill isn’t the most exciting or useful- no point in donning a cape and calling myself a superhero 😛

Hope you enjoyed this post dear Earthlings!

Autism and Dyslexia

Greetings Earthlings! 🙂

This week I’d like to take a look at another neurological condition that can be co-morbid with autism- dyslexia.

First things first, what is dyslexia?

Dyslexia can be described as a specific type of learning disability that impacts a persons reading, writing and spelling abilities. Impacting approximately 10% of the population, dyslexia ranges from mild to severe characterized by cognitive difficulties with processing phonetics, working memory and speed of long term memory retrieval. Like autism, the exact neurological causes and mechanisms are unclear, but as dyslexia can run in families, genetic factors are largely thought to contribute.

So how is it linked to autism?

The link between autism and dyslexia has not been scientifically established, but there are some commonalities. Interestingly, dyslexia overlaps with many autistic co-morbidities such as ADHD, dysgraphia, dyspraxia (an estimated 52-53% of dyslexics are also dyspraxic), and auditory processing disorders, which would suggest that these conditions likely operate through similar neurological mechanisms and pathways.

Scientists have found it difficult to establish a direct genetic link between the two conditions, however, recent research may implicate gene deletions in CNTNAP5 (a gene involved in connecting neurons)  and DOCK4 (a gene that regulates junctions between cells) in both dyslexia and autism. In addition to this, a 2015 study found that declarative memory (the type of memory that can be “declared” like names, facts, figures etc.) can be used to develop coping mechanisms for both autism and dyslexia, suggesting that perhaps there may be overlap in the brain regions associated with this type of memory formation. Other studies exploring the neural mechanisms of dyslexia indicate structural changes in such regions as the frontal lobe (memory and problem solving), cerebellum (the motor centre) and corpus callosum (the bundle of nerves that splits and connects the left and right hemispheres of the brain)- all areas that have also shown structural changes in studies of the autistic brain.

Most recently, a 2021 study exploring the co-occurrence of dyslexia and other neurodevelopmental disorders reported that many dyslexic patients in their dataset also had issues with sensory processing and other ASD traits, but concluded that the links between the two conditions are complex and hard to underpin, especially given that some autists are hyperlexic (guilty!) rather than dyslexic.

Whilst there is no definitive scientific link, the overlap cannot be denied.

Autism and Brain Zaps

Greetings Earthlings! 🙂

Leading on from my previous post about autism and anxiety, this week I’d like to talk about the phenomenon of brain zaps which autists may experience.

So what exactly are brain zaps?

Brain zaps (also know as brain shakes/shocks/shivers/flips) are a poorly understood phenomenon where it feels as though the brain is undergoing an electrical shock or a shaking/shivering/vibrating sensation. I personally have experienced these from time to time as a vibrating sensation in my brain, where it feels like your brain is literally shaking in your skull. Others report that it feels like a zap has gone off in their head and they can hear a hissing or a ringing sound in their ears. In some cases people experience bursts of light and can feel faint and disorientated afterwards. They are not harmful to the brain but they can be distracting and uncomfortable, especially for autists who are already sensitive to sensory stimuli.

So what causes them?

Like many neurological sensations, they are somewhat of a mystery, but they generally tend to occur in response to withdrawal or missed doses of certain drugs such as anti-depressants, ecstasy and MDMA, and medications for anxiety and ADHD – many of which are prescribed for co-morbid mental health conditions in autists. As these drugs alter levels of key calming inhibitory neurotransmitters such as serotonin and GABA (levels which are naturally dysregulated in the autistic brain), it is thought that low levels of these neurotransmitters may cause over-excitement in the brain, leading to abnormal firing between the neurons causing localized minor seizures i.e. brain zaps.

Don’t be alarmed by the term seizure here- this theory has not yet been confirmed and there is no evidence that brain zaps have a negative impact on our health.

On the other hand, brain zaps can also occur in response to high stress and anxiety. When you experience chronic stress, the brain is hyperstimulated as your worries swirl round and around in your restless mind. Completely overworked and overexcited from stress, your neurotransmitter levels fluctuate causing lower levels of calming GABA and higher levels of glutamate- the primary excitatory neurotransmitter. Such changes may over-excite the brain resulting in a localised seizure/brain zap as described above. Autists may be particularly susceptible to brain zaps in this manner as we experience higher levels of biological stress than our neurotypical peers, not to mention that our neurons are naturally hyper-connected, our neurotransmitters dysregulated and our brains hyperstimulated as a result.

Interestingly, a recent study has suggested that lateral eye movement may be a triggering factor for brain zaps. This is particularly intriguing for autists as evidence suggests that we process most visual information in our periphery, so our natural inclination to avoid direct eye contact could trigger brain zaps.

There are no treatments for brain zaps, but while they may not be the most pleasant sensation, they are generally nothing to be worried about and can be mitigated with proper management of stress and your prescribed medications.

Autism and the Internet

Greetings Earthlings! 🙂

This week I’d like to have a discussion about a somewhat polarizing topic- the internet and autism.

The internet is without a doubt one of the most powerful tools in the world- it connects us, shops for us, provides us with data instantly and is a vital tool in both school and the workplace. But as with most tools, it has many sharp and dangerous edges. As such, we need to be quite cognizant of both sides of the coin for vulnerable autists.

The internet often feels like a Godsend to an autist- it educates us about our condition, keeps those of us with ADHD stimulated (so many hours of online content to shut my brain up! 😛 ) and it removes the physical barriers of socializing, allowing us to make friends in a seemingly less threatening environment. Online support groups, vlogs and blogs can be immensely beneficial for autists, giving information, advice and a sense of community, knowing there are people out there dealing with the same struggles as you.

It can also really help mitigate some of the anxiety associated with in person or phone interactions. I’ve always hated shopping, so the rise in online retail during the pandemic has been very convenient for me, allowing me to offset some of the awkwardness and anxiety I would normally feel when dealing with retail workers (not to mention it’s keeping my habit of dropping/knocking things over in shops from poor coordination at bay! 😛 ). Even little things like being able to book appointments and restaurants over the internet can have a huge impact for an autist- the smallest of things can make our lives so much less stressful.

Perhaps one of the biggest benefits of the internet to emerge from the pandemic for autists is how it enables us to work remotely. With just a couple of clicks, we can work away as if we were in a physical office, safe in the comfort of our home, free from many of the stresses of workplace life.

But as useful as the internet is, it can also be a very dangerous place for autists.

The internet provides us with a vast network of information, but a large percentage of it goes un-monitored which could be dangerous in the hands of vulnerable autists. We can be quite innocent and trusting, our struggles with social cues often making it difficult to discern what is truly ingenuous. The internet is filled with harmful pages about “curing” autism which a desperate and struggling autist could take at face value. The threat of cyber bullying is a serious issue for today’s youth (I was blessed this was only taking off as I was leaving school), but autists are especially vulnerable given our social struggles. An even bigger danger may arise from these struggles as online predators may target autists, many of whom may be innocently oblivious to their potential danger.

Furthermore, there are an increasing number of studies which have identified a trend of internet addiction among autists, as we can often be vulnerable to addictive behaviours. Researchers feel that the internet allows us to compensate for our social difficulties in the offline world through online activity. The list of perceived advantages of the internet is endless to an autist, and so it can very quickly become a crutch.

Whilst we can put up filters and blocks to mitigate some of these risks, there is a real need to properly educate growing autists about the internet and the potential threats that are out there. Not just from others, but autists also need to be educated about the danger they pose to themselves with what they post on the internet. With our mimetic and impulsive nature, internet behaviours can often be monkey see-monkey do, and so we may post inappropriate content without properly realizing the potential consequences.

It’s easy to demonize it, but we cannot deny that the internet truly has provided a platform to increase visibility for the autistic community in recent years. It’s given so many of us a voice that we never knew we could have. The internet is on the whole primarily a good thing for autists, but we should always be wary of the dangers and advocate for proper education around internet usage.

Autism 101- Dyspraxia

Greetings Earthlings! 🙂

In continuation from a previous post exploring coordination issues and autism, I’d like to dedicate a specific post to the often co-morbid issue of dyspraxia.

So what exactly is dyspraxia?

Dyspraxia, like autism, is a neurodevelopmental disorder that impacts a person’s ability to plan and process motor movements. It may also be known as motor learning difficulties, perceptuo-motor dysfunction, developmental coordination disorder (DCD).

Some of the general symptoms of dyspraxia include issues with balance and hand-eye coordination, poor posture, problems with fine motor skills (like picking up and holding items like a pencil or tying shoelaces), clumsiness and issues with spatial awareness and perception. It can also cause learning difficulties, but it generally does not impact intelligence.

So how are autism and dyspraxia linked?

Dyspraxia is caused by errors in the transmission of motor messages from the brain to the body. The neurological basis for the coordination issues associated with autism is poorly understood, however, it’s believed that they occur through a similar pathway to dyspraxia. The synapse (or connecting junction point between two neurons) is thought to play a major role in motor coordination. Autist’s have an overabundance of synapses compared to their normally developing peers, so with a greater number of brain connections comes the greater potential for signals to get lost en route to their destination.

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. As autists have too many synapses connecting the brain, the purkinje cell receives signals from multiple climbing fibers. This confuses the purkinje cell, which in turn alters the efficacy of corrective signals and motor movements veer off course.

In addition to this, dopamine deficiency is thought to disrupt motor learning at the synapses, which as I’ve discussed in many previous posts, is dysregulated in the autistic brain.

Roughly 80% of autists have issues with motor coordination, but not all will also have dyspraxia. It can be difficult to differentiate between the two conditions due to the high level of overlap in symptoms.

Autism and Hormones

Greetings Earthlings! 🙂

This week I’d like to talk about the role that hormones (or horror-mones as my younger cousin used to call them) and fluctuations in hormone levels may play in autism.

So first off the basics, what exactly is a hormone?

We’ve all heard of them, but not all of us are aware of how they work.

Hormones are powerful biochemical messengers that travel through the blood in the body influencing a number of bodily changes and functions such as growth, mood, metabolism, puberty and reproduction to name but a few. Secreted by the endocrine glands of the body (e.g. adrenal glands, thyroid, pancreas etc.), it only takes a small amount of hormone to trigger large changes in the body, so fluctuations in normal hormone levels can have serious consequences for bodily functions.

So what impact do hormone changes have for autists?

Research suggests that a number of hormonal imbalances can contribute to autistic behaviours. The primary hormones thought to contribute to autism are oxytocin and vasopressin- also referred to as the “love” or “social” hormones. These hormones are involved in social bonding, trust, sexual behaviours and processing of sensory information. Studies have revealed that autists have lower levels of both of these hormones, and that treatments designed to increase these hormones may help improve social behaviours.

Most recently, new evidence suggests that growth hormone and the digestive hormone ghrelin may contribute to autism. A recent study showed that children with autism have lower levels of these hormones compared with their neurotypical peers. Ghrelin has a wide range of physiological functions such as stimulating the release of growth hormone, memory and learning, the formation of new brain synapses between neurons (i.e biochemical junctions joining one brain cell to the next) and it is involved in triggering satiety after meals (guess that explains why I’m always hungry 😛 ).

As many of these functions are disrupted in autism, low levels of these hormones likely contribute to their pathology. Moreover, ghrelin is thought to have a protective effect against reactive oxygen species in the brain which are also thought to contribute to autism (as I’ve discussed in previous posts) so reduced ghrelin levels could reduce the brains protection against these chemicals.

Hormone fluctuations are also thought to cause sleep issues for autists. The amino acid tryptophan is needed for the body to produce melatonin (aka the hormone that controls sleep and wakefulness), an amino acid which research has shown can be either higher or lower than normal in people with autism. Ordinarily melatonin is released in response to darkness (to induce sleep) with levels dropping during daylight hours (to keep us awake). However, studies have shown the opposite in some autists, where higher levels of melatonin are released during the daytime and lower levels at night- which certainly explains why I often have the urge to nap throughout the day 😛

In addition to these, higher stress hormone levels are thought to be the driving force behind a number of autistic behaviours such as meltdowns, shutdowns and issues with anxiety. As I’ve discussed in a number of previous posts, stress hormones such as cortisol and adrenaline are released in response to stressful situations from the hypothalamic–pituitary–adrenal axis or HPA axisThis is a complex interconnecting network that comprises the hypothalamus, the pituitary gland and the adrenal gland (i.e. HPA) to control our response to stress- a network that is hyperactive in autists. Following exposure to a stressful situation, stress hormone levels should return to normal, however, research has shown that stress hormone levels tend to persist in autists, which can make us more susceptible to stress related outbursts and meltdowns. In other words, we’re constantly living in a state of fight or flight. Long term activation of the stress system can lead to a number of health problems such as poor mental health, weight gain, sleep issues, digestive and cardiovascular problems to name but a few- many of which are regularly comorbid with autism.

Sex hormones are also thought to contribute to the development of autism. Research in recent years has indicated that exposure to higher levels of testosterone and/or oestrogen in the womb may predispose developing babies to autism- this is known as the sex-steroid theory of autism. It’s thought that these elevated hormone levels likely interact with genetic factors that may affect the developing brain. There is a particular trend among women who suffer from polycystic ovarian syndrome (PCOS) as the ovaries produce abnormal amounts of testosterone.

Moreover as I’ve discussed in previous posts, hormone imbalances are also thought to contribute to changes in behaviour in autistic women due to fluctuating hormone levels at different points in their menstrual cycle. In addition, behavioural changes are also associated with autistic women going through the menopause.

With the interplay of all these different hormone fluctuations, it’s no wonder our brains are a little muddled trying to cope with the constant change (as if we don’t find change hard enough! 😛 )

Hope you enjoyed this post dear Earthlings!

Autism and Personal Space

Greetings Earthlings! 🙂

Sorry I’ve been away for so long- you wouldn’t believe how hectic these past few weeks have been!

This week I’d like to ease back in by talking about the topic of autism and space!

No- not that kind of space (we’ll leave that one to the billionaires); personal space!

Personal space is an interesting subject for autists. As we’ve discussed at length, social norms can be difficult to navigate, so our sense of personal space in company can be a little unusual. Some may stand on the sidelines away from the crowd, whereas other autists can be right in your personal bubble, and perhaps even a little too close for comfort. Sometimes you just don’t know how to judge how close is too close! From a meltdown perspective, most autists tend to seek out small, enclosed spaces away from crowds when the flight response is triggered.

For me personally, I do have a tendency to seek out smaller spaces when I’m feeling overwhelmed. I have lingered for many hours in many bathrooms and stalls across Ireland during my lifetime. The comfort of the enclosed and locked space is soothing, kind of like my environment is giving me a socially distanced hug. On the other hand, I’ve equally embraced wide open spaces when my flight response get’s triggered during a meltdown. Sometimes the best thing is to just sit down in the middle of a wide open field to help you can breathe again.

So is there any research behind personal space and autism?

An interesting study from 2015 found that autists have a tendency towards shorter distances in personal space compared with neurotypicals, not just between people, but also a shorter personal space between themselves and objects. In other words, most autists may be inches from your face and will not become uncomfortable! It’s thought that this occurs due to alterations in the regulator of personal space- the amygdala in the brain, a structure that has been implicated in many autistic symptoms.

In addition to this, it’s thought that personal space is related to our propricoceptive system- the neurological feedback system in our muscles responsible for our sense of space and pressure detection. As discussed in previous posts, alterations in this neural system can lead to dysfunction and difficulties in spacial awareness. The interesting thing about this system however, is that many autists stimulate it for relief of sensory issues through stimming and deep pressure. As pressure and space are both detected through this system, it’s thought that autists may seek out enclosed spaces as a means of stimulating it for sensory relief.

So while we might seem a little bit odd hiding under the table, there is method in the madness! 😉

Hope you enjoyed this post dear Earthlings!

Enjoy the weekend!
