What is it?

Paranoia is an intense feeling or thought that is related to persecution, threat or conspiracy. Paranoia is present in many mental disorders, and is common in psychotic disorders such as schizophrenia. Paranoia may have a delusional component when the paranoia becomes fixed, until nothing can change the person's mind about it, not even contrary evidence. When paranoia is not accompanied by other symptoms such as hallucinations, it is called a delusional disorder. In many cases, paranoid states are related to events and people in a person's life, hence making the person even more lonely, with decreased access to help.
