Common signs of autism in adults include:

• finding it hard to understand what others are thinking or feeling
• getting very anxious about social situations
• finding it hard to make friends or preferring to be on your own
• seeming blunt, rude or not interested in others without meaning to
• finding it hard to say how you feel
• taking things very literally – for example, you may not understand sarcasm or phrases like "break a leg"
• having the same routine every day and getting very anxious if it changes

Other signs of autism

You may also have other signs, like:

• not understanding social "rules", such as not talking over people
• avoiding eye contact
• getting too close to other people, or getting very upset if someone touches or gets too close to you
• noticing small details, patterns, smells or sounds that others do not
• having a very keen interest in certain subjects or activities
• liking to plan things carefully before doing them

Autism in women and men

Autism can sometimes be different in women and men. For example, autistic women may be quieter, may hide their feelings and may appear to cope better with social situations. This means it can be harder to tell you're autistic if you're a woman.
