Progression of Parkinsonian Signs in Alzheimer's Disease
Neurol 54:1284-1289, Wilson,R.S.,et al, 2000
See this aricle in Pubmed

Article Abstract
Rates of change in bradykinesia (4.5% increase per year), rigidity (6.0% increase per year), and gait disorder/postural reflex impairment (8.9% increase per year) were substantial and positively correlated (median r=0.69). Change in tremor was minimal, mostly confined to postural tremor, and weakly correlated with change in other signs (median r = 0.16). The rate of progression in each sign was highly variable across individuals and not strongly related to demographic factors or use of neur oleptic medications. Parkinsonian signs other than tremor progress rapidly in AD but at widely differing rates.
