Motor fluctuations in Parkinson's disease

Area of Science:

• Neurology
• Movement Disorders

Background:

• Parkinson's disease (PD) is a progressive neurodegenerative disorder causing bradykinesia, rigidity, and tremor.
• Levodopa is a primary treatment for motor dysfunction in PD, but motor fluctuations are common.
• Motor fluctuations include "end-of-dose wearing-off" and "morning akinesia," where PD symptoms return as medication wears off.

Purpose of the Study:

• To review the management strategies for motor fluctuations in Parkinson's disease.
• To discuss the various pharmacological and non-pharmacological options available.

Main Methods:

• Review of existing literature on Parkinson's disease motor fluctuations.
• Discussion of therapeutic options including medication adjustments and additions.
• Consideration of surgical interventions like deep brain stimulation.

Main Results:

• Motor fluctuations are a significant challenge in long-term Parkinson's disease management.
• Treatment choices involve adjusting levodopa/carbidopa dosage or adding other medications.
• Available adjunct therapies include dopamine agonists, COMT inhibitors, MAO inhibitors, and amantadine.
• Dietary changes can also play a role in managing motor fluctuations.

Conclusions:

• Managing motor fluctuations in Parkinson's disease requires a personalized approach.
• While head-to-head comparisons of adjunct therapies are limited, various options offer potential benefits.
• Deep brain stimulation is a viable option for patients with medically intractable motor fluctuations.
