What causes autism (and is this really what we should be focussing on)?🪡

A substantial focus of autism research has been on its causes rather than ways to improve our lives.

However, as some have theorised 'gut bacteria' to be a cause, I think it may be useful to share what research has found.

The causes of autism are not properly understood, but strong evidence points to genetics. Additional, inconsistent, and limited research suggests environmental and neurological factors may also play a role.

Autism is highly heritable (approximately 80%), and may be associated with gene variants (both inherited and rare).

Families who have an autistic child also have a 25 times higher likelihood that their next child will be autistic.

Various prenatal, perinatal, and postnatal factors have also been suggested to contribute to autism if combined with genetic factors. However, findings are inconsistent and studies are largely limited by their design.

Differences in gut bacteria have led some to theorise this may cause autism. However, recent research suggests these differences are driven by our sensory sensitivities and restrictive diets.

Neurological factors have also been suggested to contribute to autism, including potential differences in childhood neural connectivity, and differences in specific brain regions. However, findings are largely inconsistent.

Regardless of what causes autism, it's an integral and inseparable part of who we are and not something that can be "cured".

Rather, I believe more attention should be directed towards social inclusion and understanding of autistic people, and ways to improve our lives.
