This study investigated if donepezil, a drug that boosts acetylcholine, can improve balance and walking in Parkinson's disease (PD) patients. Results will guide future treatments for mobility issues in PD.
Area of Science:
- Neuroscience
- Movement Disorders
- Pharmacology
Background:
- Parkinson's disease (PD) significantly impairs mobility and balance, reducing quality of life.
- Cholinergic system degeneration is implicated in PD-related gait and balance deficits.
- Current therapies for PD-related mobility issues are limited.
Purpose of the Study:
- To examine the effects of augmenting the cholinergic system on balance and gait in PD patients.
- To determine the potential utility of cholinergic manipulation for preventing or treating gait and balance dysfunction in PD.
- To explore the role of cholinergic neurotransmission in PD-related motor impairments.
Main Methods:
- A single-site, randomized, double-blind, cross-over trial involving patients with idiopathic Parkinson's disease (Hoehn and Yahr stages 2-4).
- Participants received either donepezil or placebo for 6-week periods, separated by a 6-week washout.
- Primary outcomes included postural sway and walking stride variability; secondary outcomes assessed attention and cholinergic activity via Short-latency Afferent Inhibition (SAI).
Main Results:
- This section is not available in the provided abstract.
- This section is not available in the provided abstract.
- This section is not available in the provided abstract.
Conclusions:
- This study directly tests the hypothesis linking cholinergic neurotransmission to gait and balance in PD.
- Findings will inform future, larger trials on the clinical utility of cholinergic manipulation for PD mobility.
- The study aims to establish if donepezil can improve gait, balance, and attention in PD patients.

At the neuromuscular junction, these agents work by inhibiting the breakdown of acetylcholine, allowing it to remain bound to the receptor and bind to nearby receptors. This process leads to repetitive firing of the endplate, causing muscle...
