When an adult has Asperger's Syndrome some symptoms to look out for are.
Problems making or maintaining friendships.
Isolation or minimal interaction in social situations.
Poor eye contact and/or the tendency to stare at others.
Trouble interpreting gestures.
The Inability to recognize humor, irony, and sarcasm.
Difficulty with social and communication skills and sensitivity to loud noise, bright lights etc.
Sometimes but not always talk therapy or other counseling may help with Asperger's Syndrome although there's no 100% way of curing Asperger's Syndrome once someone has it.
