Document Summary
Loss of eye blink & facial tone (mask-like face) Dementia with lewy bodies (dlb) is a distinct form of dementia that appears early and has associated features of pd (may be secondary to alzheimer"s in prevalence) Stooped posture (bent over slightly or to one side) Incidence : risk of contracting pd increases with age. 100,000 with parkinson"s disease in canada (13,000 in bc) Up to 20% of individuals develop symptoms before age 60. However, 40% of pd may be undiagnosed at any time. Progression rate of progression is variable and hard to predict. Older age at onset may be the best indicator. Less rapid progression: tremor as the presenting symptom. Damage is in the basal ganglia of the brain. Genetic cases exist (> 16 genes now associated with genetic causes or risk of pd) 5 genes are associated with rare, monogenic forms of parkinson"s.
