Significance of motor features associated with Alzheimers Disease
What motor features may be associated with Alzheimers Disease? What is their significance?
Rigidity, bradykinesia, and parkinsonian gait may be associated with more rapid progression of disease (both cognitive decline and activities of daily living).
Tremor is rare, differentiating patients with Alzheimers Disease from patients with Parkinson’s disease to some extent.
Myoclonus may occur, and recent evidence suggests its association with a younger age of onset of Alzheimers Disease.
In very severe Alzheimers Disease, patients may have gait apraxia.
