Autism and Stress

Greetings Earthlings! 🙂

Stress- it’s hard to escape it in the modern world; even more so for an autist.

Ordinary day to day life can be very stressful to navigate. Such simple things as responding to an email, dealing with crowds, sensory triggers and social interactions can be completely overwhelming. The thought alone of these seemingly innocuous situations can be incredibly stressful for an autist.

In my case, just the mere idea of driving in Dublin city centre for example majorly stresses me out- I have genuinely told my friend that if his directions landed us there I would get my car towed and grab a taxi 😛 Any unexpected scenarios, detours or maneuvers in my car will leave me hot under the collar, praying out loud for help to keep from freaking out!

But are there any scientific reasons why autists are more predisposed to stress?

Interestingly, autists show signs of greater biological stress than their neurotypical peers. In particular, studies have indicated that autists have higher levels of stress hormones than neurotypicals. As I’ve previously discussed, stress hormones such as cortisol and adrenaline are released in response to stressful situations from the hypothalamic–pituitary–adrenal axis or HPA axis. This 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.

In addition to this, studies have shown that autists have higher levels of oxidative stress in the body. Oxidative stress occurs when there is an imbalance between anitoxidants and free radicals (unstable oxygen atoms that can damage cells causing illness and aging – not so fun fact, free radicals are thought to contribute to hair greying) in our bodies. Several studies have indicated that antioxidant enzyme levels that regulate free radicals in the body may be altered in autists. As such, oxidative stress has been linked to the appearance of autistic symptoms such as language delay in previous studies.

In addition, as with prolonged exposure to stress hormones, oxidative stress may also contribute to the development of cardiovascular disease and mental health problems such as depression. Worryingly, heart disease and suicide are among the leading causes of mortality for autists, with studies indicating that the average autist lives 16 years less than their neurotypical peers! 😲  In addition to this, research suggests that psychological stress may worsen the symptoms of ASDs.

Therefore, as for everyone, it’s very important for an autist to find ways to manage their stress levels for both their long term physical and mental health.

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? 😲

bitmoji1256098968In 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.

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.
