Many mental health disorders share some similar symptoms with schizophrenia. Some personality disorders share symptoms with schizophrenia, including paranoid personality disorder, schizoid personality disorder, and schizotypal personality disorder. Other mental health disorders may also share some features with schizophrenia. A brief psychotic disorder has similar qualities to schizophrenia but lasts less than one month, as opposed to schizophrenia, in which the presentation of symptoms continue for at least six months at a time.

Schizophreniform disorder is also similar to schizophrenia, but lasts between one and six months.

Some medical conditions also can cause symptoms that are similar to schizophrenia.
