Psychotic symptoms lasting less than a month may be diagnosed as brief psychotic disorder , and various conditions may be classed as psychotic disorder not otherwise specified ; schizoaffective disorder is diagnosed if symptoms of mood disorder are substantially present alongside psychotic symptoms.

The ICD defines additional subtypes: . Psychotic symptoms may be present in several other mental disorders, including bipolar disorder ,  borderline personality disorder ,  drug intoxication, and drug-induced psychosis.
Delusions "non-bizarre" are also present in delusional disorder , and social withdrawal in social anxiety disorder , avoidant personality disorder and schizotypal personality disorder.

Stroke , multiple sclerosis , hyperthyroidism , hypothyroidism , and dementias such as Alzheimer's disease , Huntington's disease , frontotemporal dementia , and the Lewy body dementias may also be associated with schizophrenia-like psychotic symptoms. Investigations are not generally repeated for relapse unless there is a specific medical indication or possible adverse effects from antipsychotic medication.
In children hallucinations must be separated from typical childhood fantasies. Prevention of schizophrenia is difficult as there are no reliable markers for the later development of the disorder.

The first-line psychiatric treatment for schizophrenia is antipsychotic medication,  which can reduce the positive symptoms of psychosis in about 7 to 14 days. Antipsychotics fail to significantly improve the negative symptoms and cognitive dysfunction. The choice of which antipsychotic to use is based on benefits, risks, and costs.
Most people on antipsychotics have side effects. People on typical antipsychotics tend to have a higher rate of extrapyramidal side effects ; some atypicals are associated with considerable weight gain, diabetes and risk of metabolic syndrome. This is most pronounced with olanzapine; risperidone and quetiapine are also associated with weight gain.

Schizophrenia: Symptoms, causes, and treatments
In the early 20th century, the psychiatrist Kurt Schneider listed the forms of psychotic symptoms that he thought distinguished schizophrenia from other psychotic disorders. These are called first-rank symptoms or Schneider's first-rank symptoms. They include delusions of being controlled by an external force, the belief that thoughts are being inserted into or withdrawn from one's conscious mind, the belief that one's thoughts are being broadcast to other people, and hearing hallucinatory voices that comment on one's thoughts or actions or that have a conversation with other hallucinated voices.
A review of the diagnostic studies conducted between and found that they allow neither a reconfirmation nor a rejection of Schneider's claims, and suggested that first-rank symptoms should be de-emphasized in future revisions of diagnostic systems. The history of schizophrenia is complex and does not lend itself easily to a linear narrative.
