I am in my twenties and I recently got diagnosed with Aspergers. I actively sought out the diagnosis because I thought it might be helpful to me. It hasn't been, really. It has actually made me feel disappointed that the signs of AS weren't noticed when I was a child. I have read that early diagnosis is crucial with autism and AS because by adulthood, a person's thoughts, perceptions and behaviors have become too deeply entrenched to be changed, so that therapies and treatments are of limited use. In my case, after over 20 years of missing social cues, not understanding sarcasm and jokes, speaking with a monotone voice, being socially awkward and aloof, and struggling to fit in and make friends (along with non-social stuff such as sensory issues, adhering to the same routines, and being unable to cope with disruption to those routines), I feel it is too late for me to change. Is there anyone on MN who got diagnosed later on in life? If so, did you find the diagnosis helpful at all?
