The term antipsychotic is applied to a group of drugs used to treat psychosis. Common conditions with which antipsychotics might be used include schizophrenia, mania and delusional disorder, although antipsychotics might be used to counter psychosis associated with a wide range of other diagnoses. Antipsychotics also have some effects as mood stabilizers, leading to their frequent use in treating mood disorder (particularly bipolar disorder) even when no signs of psychosis are present. Some antipsychotics (haloperidol, pimozide) are used to treat Tourette's Syndrome. These drugs are also referred to as n ...

Amphetamine psychosis can include delusions, hallucinations and thought disorder. This is thought to be largely due to the increase in dopamine activity in the mesolimbic pathway of the brain caused by amphetamine-like drugs, although other factors such as chronic sleep deprivation may also play a part. The link between amphetamine and psychosis is one of the major sources of evidence for the dopamine hypothesis of psychosis. The link between amphetamine and psychosis was first made by Young and Scoville in 19381 and was or ...

Disruption to the dopamine system has also been strongly linked to psychosis and schizophrenia. Dopamine neurons in the mesolimbic pathway are particularly associated with these conditions. This is partly due to the discovery of a class of drugs called the phenothiazines (which block D2 dopamine receptors) that can reduce psychotic symptoms, and partly due to the finding that drugs such as amphetamine and cocaine (which are known to greatly increase dopamine levels) can cause psychosis. Because of this, most modern antipsychotic m ...
