It certainly does run in families. My husband’s and mine. Youngest son was diagnosed with Aspergers in elementary school though he didn’t have all of the symptoms normally seen in these kids. He always looks people right in the eye and has a good sense of humor.
A lot of the things he used to do that caused the diagnosis he seems to have out-grown.
I do believe that if someone is on the higher end of the spectrum they can outgrow it or learn to cope.
My grand son was DX'ed on the low end. He was less than 2 years old and they use a scale of 0, no autism to 26. most severe. He was at 23 or 24. Since they use the same scale, no matter the age of the person, I am hoping that some of the reason for the severe DX was just because of him immaturity. He has made a lot of progress with therapy. He has great parents and his papaw and I are very involved with him and his therapy. He seems to have a special bond with his papaw (sometimes hard for me to accept) and seems to have more breakthrough progress when papaw takes him to therapy.
Yes, out growing of traits is possible.
They are just “different”.
We all have weaknesses and strength. But the clustering of traits is obvious.
I’ve wondered if birth control pills play a role in this and other mental and physical disorders.
