Persons experiencing a psychotic episode may experience hallucinations (often auditory or visual hallucinations), hold paranoid or delusional beliefs, experience personality changes and exhibit disorganized thinking.

Refers to any mental disorder characterized by severe distortion of thinking, comprehension, and judgment (i.e., mental capacity); impaired contact with reality; and abnormal emotional responses and disorganized behaviors. Symptoms may include false beliefs despite evidence to the contrary (delusions), such as fears of persecution; the perception of sounds, sights, or other sensations in the absence of external stimuli (hallucinations); apparent lack of emotion (affect); abnormal thought patterns; disorganized, incoherent speech; and/or agitated, aggressive behaviors. Psychosis may be of physical (i.e., organic) origin, such as due to brain damage, neurological diseases, underlying metabolic disorders, etc., or "functional," meaning that it is produced or caused by factors other than organic disease.
A severe disorder of behaviour, feeling, and thinking. Contact with reality is impaired, and there may be hallucinations and delusions. The psychoses may be classified into "organic" (dementia) and "functional" (depression and schizophrenia). Both are very rare sequelae of blunt head injury.

Describes conditions which affect the mind, where there has been some loss of contact with reality. When someone becomes ill in this way it is called a psychotic episode. Psychosis can lead to changes in mood and thinking and abnormal ideas, making it hard to understand how the person feels. First episode psychosis simply refers to the first time someone experiences psychotic symptoms or a psychotic episode.
A mental and behavioral disorder causing gross distortion or disorganization of a person's mental capacity, affective response, capacity to recognize reality, and ability to communicate with or/and relate to others to an extent that interferes with the person's capacity to cope with the ordinary demands of everyday life. The psychoses are divided into two major classifications according to their origins: 1) those associated with organic brain syndromes (e.g., Korsakoff's syndrome), and 2) those less strictly organic and having some functional component(s) (e.g., schizophrenia). Although psychosis is a generic term for a variety of insanities, schizophrenias are the most common forms of psychoses.

Psychosis is a generic psychiatric term for a mental state in which thought and perception are severely impaired. Persons experiencing a psychotic episode may experience hallucinations, hold delusional beliefs (e.g., grandiose or paranoid delusions), demonstrate personality changes and exhibit disorganized thinking (see thought disorder). This is often accompanied by lack of insight into the unusual or bizarre nature of such behaviour, difficulties with social interaction and impairments in carrying out the activities of daily living.
A state in which it is difficult to distinguish between the real and not real. Overwhelmingly not a state of violent impulses. May be hard to discriminate from the beliefs of ordinary people such as alien abductions and the presence of weapons of mass destruction in Iraq.
