Psychotic disorders are a group of serious illnesses that affect the mind. These illnesses alter a person's ability to think clearly, make good judgments, respond emotionally, communicate effectively, understand reality and behave appropriately.

  1. Symptoms vary from person to person and may change over time. The major symptoms of psychotic disorders are hallucinations and delusions.
  2. Hallucinations are unusual sensory experiences or perceptions of things that aren't actually present, such as seeing things that aren't there, hearing voices, smelling odors, having a "funny" taste in your mouth and feeling sensations on your skin even though nothing is touching your body.
  3. Delusions are false beliefs that are persistent and organized, and that do not go away after receiving logical or accurate information. For example, a person who is certain his or her food is poisoned, even if it has been proven that the food is fine, is suffering from a delusion.
  4. Other possible symptoms of psychotic illnesses include:
  5. Disorganized or incoherent speech
  6. Confused thinking
  7. Strange, possibly dangerous behavior
  8. Slowed or unusual movements
  9. Loss of interest in personal hygiene
  10. Loss of interest in activities
  11. Problems at school or work and with relationships
  12. Cold, detached manner with the inability to express emotion
  13. Mood swings or other mood symptoms, such as depression or mania
