Elevated growth hormone responses to pyridostigmine in obsessive- compulsive disorder: evidence of cholinergic supersensitivity
Abstract
The growth hormone response to the acetylcholinesterase inhibitor pyridostigmine was measured in nine normothymic outpatients who met DSM- III-R criteria for obsessive-compulsive disorder. The responses were significantly elevated when compared to those found in a healthy comparison group (N = 9). The data suggest that cholinergic supersensitivity is present in obsessive-compulsive disorder.
