帕金森病和老年痴呆在一些方面存在相关性,但并非所有帕金森病患者都会发展为老年痴呆。研究表明,帕金森病患者患上老年痴呆的风险要比一般人群略高。大约1/4到1/3的帕金森病患者会在10年内进展为痴呆。这种形式的痴呆被称为帕金森病相关痴呆(Parkinson's disease dementia ,PDD)。 帕金森病相关痴呆主要表现为认知功能下...
Parkinson's disease with dementia (PDD) is now recognised as a major clinical consequence of idiopathic Parkinson's disease (PD). Indeed the cumulative prevalence of dementia in PD is very high; up to 80% of patients will develop dementia within 10 years of their Parkinson's diagnosis. The ...
