title: Anticholinergic syndrome. Avoiding misdiagnosis.
abstract: Anticholinergic syndrome can develop in multiple clinical situations. The disturbance of the central nervous system muscarinic transmission by acetylcholine antagonists or lack of acetylcholine can result in this unpredictable behavioral syndrome. Health care professionals should do the following: Be familiar with common drugs or drug combinations that may induce this condition; Be aware of patients who may be at greatest risk; Be able to identify the cluster of signs and symptoms of anticholinergic toxicity; and Implement appropriate nursing treatment interventions for patients with anticholinergic syndrome. Because this condition is constantly changing, it often is misdiagnosed. Much remains to be studied and understood about the neurophysiology of this condition. Central cholinergic transmission is blocked with the use of many anticholinergic drugs in numerous patient settings. Because acetylcholine plays a significant role in modulating the interactions among most other central transmitters, excessive blockage of this neurotransmitter may result in the unpredictable behavioral condition known as anticholinergic syndrome.
