General Discussion

Organic personality syndrome or organic mental syndrome is a mental disorder characterized by a short-term or long-term personality disturbance largely due to brain dysfunction. The ability to reason, remember, imagine, and learn may not be affected, but the individual's judgment may be so poor that continual supervision may be necessary. Left unattended, he or she may behave in ways that could cause difficult or dangerous problems.
