Youth who are psychotic have an impaired sense of reality. They may have hallucinations: hearing or seeing things that are not really there. They may have delusions: holding on to irrational beliefs even though there is much evidence that the belief is not true. These youth may behave in bizarre ways and often have a difficult time relating to others. Psychosis can result from a variety of causes including schizophrenia, severe mood disorders, or a medical condition. Substance use can also result in psychotic symptoms. Some youth who use LSD report visual hallucinations even after discontinued drug use, and youth who use large amounts of drugs, particularly methamphetamines, can become extremely paranoid and develop delusions that people are after them.
Psychoctic Disorders is a generic psychiatric term for mental states in which the components of rational thought and perception are severely impaired.

This is often accompanied by lack of insight into the unusual or bizarre nature of such behavior, difficulties with social interaction and impairments in carrying out the activities of daily living. A psychotic episode is often described as involving a "loss of contact with reality".
