This disorder is characterized by three or more of the following symptoms:

1. Odd appearance or behavior.
2. Peculiar coping mechanisms that do not seem to follow any logical train of thought.
3. Fumbling with language to the point of gross disorganization.
4. Odd perceptions that can range from illusions to hallucinations.
5. Strange beliefs that fluctuate wildly depending on context.
6. Wildly wavering opinions on others -- that is, a fluctuation between idealizing and devaluing people.

These symptoms must cause some sort of impairment in everyday functioning, social skills, and workplace skills.
