Malingering and associated syndromes.

Malingering is the false and fraudulent simulation or exaggeration of physical and/or psychological symptoms. It is not a mental disorder, but rather a behavior pattern that may coexist with objectively diagnosed disease. Whatever form it takes, malingering is defined as conscious, voluntary, goal-directed behavior; the presence of a clearly definable goal differentiates malingerers from those with other forms of factitious illness.
