Autistic Depression Rates surveyed

Post Reply New Topic

- Depression affects almost 20 percent of young adults with autism, new research shows, a rate that's more than triple that seen in the general population.

And young adults with autism who were relatively high-functioning -- meaning they did not have intellectual disabilities -- were actually at higher risk of depression than people with more severe forms of autism, British researchers found.

In the study, this higher-functioning subgroup was more than four times as likely to suffer from depression, compared to people without autism.

People with autism without intellectual disabilities "may be particularly prone to depression because of greater awareness of their difficulties," the researchers theorized.

The study was led by Dheeraj Rai, of the University of Bristol. His team published the findings online Aug. 31 in JAMA Network Open.

According to one U.S. expert, the findings mirror what many in the autism field have seen.

"Given the considerable social struggles that individuals with an autism spectrum disorder experience, it is not surprising that they are at significantly increased risk for depression," said Dr. Andrew Adesman. He directs developmental and behavioral pediatrics at Cohen Children's Medical Center in New Hyde Park, N.Y.

In the study, Rai's group looked at data that tracked almost 224,000 Swedes living in a particular county between 2001 and 2011. A total of 4,073 had been diagnosed with an autism spectrum disorder.

Tracking the participants' mental health, the study found that by their mid-to-late 20s, 19.8 percent of people with autism had a history of depression, compared to just 6 percent of those in the general population.

The finding that autism without intellectual disability carried higher odds for depression highlights the need for earlier diagnosis, the researchers said.

"Many individuals with autism spectrum disorder, especially those without cognitive impairments, receive a delayed diagnosis, often after experiencing other psychiatric problems," the study authors wrote.

"Individuals receiving a diagnosis of autism spectrum disorder later in life often report long-standing stress in relation to social isolation, bullying, exclusion, and the knowledge they are different without the explanatory framework of [a diagnosis of] autism spectrum disorder," the researchers pointed out.

That can take a big psychological toll, perhaps contributing to depression risk, Rai's team suggested.

Dr. Peng Pang directs child and adolescent psychiatry at Staten Island University Hospital in New York City. Peng also believes more research is needed to tease out the experiences and stigmas that may contribute to depression in young people with autism.

I would think those with other disabilities too suffer from depression at a higher rate in general compared to the rest of society.

I agree that people with other neurological disorders/disabilities are also more likely to suffer from depression than NT's,however,people with other neurological disorders/disabilities are treated so much better than Aspie/Autistic people and are given more of a chance,therefore probably less depressed than Aspie/Autistic people.Also there isn't as much negative propaganda with other Neurological disorder as there is are Aspies/Autistic people.
