Psychosis is characterized by some degree of loss of contact with reality. Psychosis is a collection of symptoms that can include hallucinations, delusions, difficulty speaking, and abnormal movements. Psychosis can be associated with certain psychiatric conditions, such as schizophrenia or bipolar disorder. It can also be brought on in cases of sleep deprivation or by drugs or alcohol. Psychosis can be treated with a combination of medication and psychotherapy. After an initial episode of psychosis, seeking treatment immediately is critical for preventing further episodes.
