Autism and Eating Disorders

Greetings Earthlings! 🙂

This week I’d like to talk about a very common issue, particularly for women with autism- eating disorders.

As discussed previously, mental health issues are quite prevalent among the autistic population. Because of this, many autists can go un-diagnosed as co-morbid mental health issues often mask the root autism diagnosis. This is particularly true of eating disorders for female autists where doctors will diagnose an eating disorder, but due to social masking tendencies will often overlook their autistic traits.

In fact this should really be one of the first things that doctors should assess when patients present with eating disorders as numerous studies have shown that there is a higher prevalence rate of autism in patients diagnosed with eating disorders (up to 20%). Evidence indicates that patients presenting with anorexia nervosa, bulimia nervosa and binge eating disorder (BED) have greater numbers of autistic traits than the general population.

Autists will often not benefit from conventional treatment for disordered eating so it is critical that it is identified early.

So why are eating disorders so prevalent for those on the spectrum?

The reasons are varied, but tend to be either psychological or sensory related:

Psychological:

Some people on the spectrum develop eating disorders as a means to fit in, to attain the kind of figures that they see in magazines and perceive to be “perfect” or “normal”. Others develop eating disorders as a means of control, where the routine and rigidity can be a source of comfort to an anxious mind running on overdrive (interestingly this may have a scientific basis as starvation decreases levels of serotonin, which is heavily involved in anxiety and is often elevated in autism). Moreover, if exercise or particular foods become specialist interests, an autist may obsess and inadvertently develop a disorder as a result.

In some cases an eating disorder may be a simple matter of mind blindness where an autist simply does not understand that their eating behaviours are abnormal or dangerous.

Sensory:

Sensory issues are commonplace for autists both with and without an eating disorder. An autist may be sensitive to different tastes, textures and smells which can make for a very restrictive diet depending on the severity. In some cases, eating may be so stressful that they may not eat very much at all to avoid an unpleasant sensory event.

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.
