How to know if i have aspergers or schizotypal?

Formal psychologic: assessment can help to determine what is going on. Psychological testing may or may not be used in addition. Take care.

Differential: diagnosis is the term for sorting out the difference between two conditions that have overlapping symptoms. Making the type of diagnosis you seek can't be done w/out professional help. When a mental health professional makes the diagnosis, appropriate treatment can be offered. Peace and good health.

Eval: The best way is to NOT diagnose yourself. Either of these disorders can be looked up online, but it's best to get a full psychiatric evaluation, rather than diagnosing yourself, as these disorders can be severe.
