Manage drug-induced parkinsonism through early recognition of the condition and discontinuation of the causative agent
- 57 Downloads
Parkinsonism can be induced by many drugs, particularly dopamine receptor antagonists. Key strategies for managing drug-induced parkinsonism include prompt diagnosis and discontinuation or replacement of the offending drug. If symptoms persist, pharmacotherapy and electroconvulsive therapy are options.
Prevalence is increasing
Drug-induced parkinsonism is a reversible, pharmacotherapy-induced, rigid-akinetic syndrome that develops as a result of diminished stimulation of dopamine D2 receptors in the striatum. Although estimations of the prevalence and incidence of the condition vary greatly, its prevalence appears to be growing as populations age and use of polypharmacy increases. Drug-induced parkinsonism is now considered to be the most widespread secondary parkinsonism in Western countries, yet is still under-recognized and could become a considerable future health concern. This article summarizes a recent review on the prevention and management of drug-induced parkinsonism by...
