Pharmacologic Management of Parkinsonism and Other Movement Disorders

Abstract

Parkinsonism and other movement disorders constitute a diverse group of neurodegenerative conditions characterized by disturbances in motor control. This abstract provides an overview of the pharmacologic management strategies employed in the treatment of these disorders. Parkinson's disease, the most prevalent form of Parkinsonism, is primarily managed through dopaminergic therapies aimed at replenishing dopamine levels or enhancing its effects in the central nervous system. Levodopa, a precursor of dopamine, remains the gold standard, often combined with dopaminergic agonists or monoamine oxidase-B inhibitors for optimal efficacy.In addition to Parkinson's disease, other movement disorders such as essential tremor, dystonia, and chorea pose unique challenges. Beta-blockers and anticonvulsants, like primidone, are commonly prescribed for essential tremor, while dystonia may respond to anticholinergic agents or botulinum toxin injections. Huntington's disease, characterized by chorea, is managed through dopamine-depleting agents, tetrabenazine being a notable example.Recent advances in pharmacotherapy include the development of adenosine A2A receptor antagonists and glutamate receptor modulators, providing promising alternatives and adjuncts to traditional therapies. However, challenges such as medication-induced side effects, disease progression, and the need for personalized treatment plans persist.This abstract underscore the evolving landscape of pharmacologic interventions for managing Parkinsonism and other movement disorders. A comprehensive understanding of the underlying pathophysiology, coupled with ongoing research efforts, promises to enhance therapeutic options and improve the quality of life for individuals affected by these debilitating conditions.
