Psychotic Disorders are severe mental illnesses that cause thinking and perception abnormalities. It can make people lose a sense of reality. There are two main symptoms: hallucinations (incorrect perceptions such as seeing, hearing things that are not there) and delusions (ie thinking people may be plotting against them). Some examples of psychotic disorders are schizophrenia and sometimes bipolar disorder. Other conditions may cause psychosis such as alcohol, some drugs, brain infections, tumour and stroke.
Treatment includes therapy, prescribed drugs to alleviate some of the symptoms and sometimes hospitalisation if people are at risk of harming themselves or others.
