The average age of onset for the first psychotic episode of schizophrenia is in the 20's. Delusions are typically persecutory or grandiose, or both. Hallucinations are also typically related to the content of the delusional theme. An individual may exhibit inappropriate grimacing, giggling, or other mannerisms and oddities of behavior. Other indications are extreme negativism, mutism, and echolalia.
Echolalia is a parrot-like repetition of a senseless word or phrase.
The individual may also exhibit a behavior called echopraxia. Echopraxia is the repetitive imitation of another person's movements. These pages are solely for public informational purposes.
