They have the right to know imo. When to tell them I'm not too sure myself, but better sooner than later. I'd definitely not hide it from them forever. Otherwise they'll end up blaming their mistakes and failures on them not being strong enough. Kids are really hard on themselves nowadays because society forces them to. Autism doesn't make things easier. In fact, our good friend Wikipedia writes this:
Quote:
Many studies have found very high rates of suicide in people with autism spectrum disorders, including high functioning autism and what was formerly known as Asperger syndrome. Autism and particularly Asperger syndrome are highly associated with clinical depression and as many as 30 percent or more of people with Asperger syndrome also suffer from depression. [37]
One study found that children with autism are 28 times more likely to ideate or attempt suicide than the general population. [38] This is possibly even higher than the rate among rape survivors, who are 13 times more likely than non-crime victims to attempt suicide. [39]Another study found that being an adult and having Asperger syndrome increases the suicide risk 10 fold. [40]
This may be related to the shunning, harassment, and violence that is commonly perpetrated upon people with autism. One study found that 18.5% of American children with autism had been physically abused and 16.5% had been sexually abused [41] People with autism are much more likely to be sexually abused than the general population. [42]
Another possible factor is the likely increased prevalence of chronic pain in people with autism, contrary to the popular belief that autistic people are insensitive to pain. [43] Autism has been found to be closely related to fibromyalgia, a common chronic pain disorder. [44]
There's a good amount of sources included; Google is your friend if you're interested in those.
