Psychotic disorders are a group of mental health conditions that affect how a person thinks, feels, and behaves. They can cause problems with perception, such as hallucinations or delusions, which means seeing or hearing things that are not real or having false beliefs. They can also affect mood, motivation, and social functioning. Psychotic disorders can be treated with medication, therapy, and support from others. Some examples of psychotic disorders are schizophrenia, bipolar disorder, and schizoaffective disorder.
