Psychotic disorders are mental disorders in which a person’s personality is severely confused and they lose touch with reality. When a psychotic episode occurs, a person becomes unsure about what is real and what isn’t, and usually experiences hallucinations, delusions, uncharacteristic behavior, chaotic speech and incoherency. A person behaving in this manner is often referred to as being schizophrenic.

A hallucination is an internal sensory perception that isn’t actually present and can be either visual or auditory. Smelling odors or having a funny taste in the mouth are other hallucinations that may occur. A delusion is defined as a false, inaccurate belief that a person holds on to. A grandiose delusion occurs when a person believes that their life is out of proportion as compared to what is really true. For example, a patient may believe that she is God or Jesus Christ. A persecutory delusion occurs when a person believes that there is a conspiracy amongst others to attack, punish or harass him. Although these hallucinations and delusions appear odd to others, they are very real to the person with the disorder.
