Can i get a autism assessment as a adult i have a hard time making eye contact and i don't understand social rules and i'm sensitive to loud noises?

Please start with your primary care provider for an initial assessment and to ascertain if you may need to consult a specialist. You should do it at your earliest convenience. There is no reason to live with this doubt. Wish you good health!

You can get such an assessment. If at all possible, it would be helpful if the professional making the assessment were able to ask relatives or close friends who knew you as a young child - about various symptoms of autism.
