Autism and Mood Disorder

The perception and regulation of emotions are obviously challenging for Autistic people.

Genetics and physiology are linked..as many persons with Autism are also diagnosed with mood disorders.

There is a lot of incidences of people with Autism having mood disorders and or depression and anxiety. People with autism are bombarded with sensory overloads, social confusion, bullying, and so many other daily challenges which are depressing.
So perhaps we could deduce that Autism causes the mood disorder but treating the mood swings with medication can reduce anxiety and allow for learning adaptive skills that make daily life easier and more enjoyable.

I dont even think it really matters if they are co morbid disorders. As long as treatment of some symptoms makes quality of life better.
