Factitious Disorder in a Patient Claiming to be a Sexually Sadistic Serial Killer.

Factitious disorder involves the conscious simulation of psychological or physiological symptoms of illness, for the purpose of fulfilling the unconscious desire to be taken care of or to assume the "sick role." Typically patients with factitious disorder simulate conditions that are designed to arouse feelings of empathy in care providers with the intention to engage them in caretaking. However, patients might also simulate conditions that arouse revulsion or rejection and still meet full diagnostic criteria for factitious disorder.

The neuropsychiatric manifestations of Huntington's disease-like 2.

Huntington's disease-like 2 (HDL2) is a rare neuropsychiatric disorder that resembles HD but results from a distinct mutation. The authors present a patient with HDL2, hospitalized for psychiatric management, and they review the neuropsychiatric manifestations of this disorder. Depression, irritability/aggression, and frontal lobe personality changes are common presentations of HDL2 and are comparable to classic HD.
