My husband has most the signs of broad spectrum autism. No eye contact, doesn't communicate well, if he does at all. Has a routine he follows Every night without deviation. Doesn't care to be hugged or touched much at all. The only time he can start a conversation is if he's talking about his favorite music. He just always seems uncomfortable out of the house. I have family members that brought it to my attention becuz she has a 14 yr old that was just diagnosed with Asbergers. Can he b diagnosed at 31?
