Neuropsychologic studies on Parkinson's disease have shown an impairment of specific cognitive functions and a greater evidence of dementia. Cognitive alterations are related to the gravity of some peculiar motor symptoms of the disease and show a major role of motor disturbances in intellectual disorders. The concept of bradyphrenia and subcortical dementia still seems to be suitable to define the cognitive disorders of Parkinson's disease.
对帕金森病的神经心理学研究表明，特定认知功能存在损害，且有更多证据表明存在痴呆。认知改变与该疾病某些特殊运动症状的严重程度相关，并且显示出运动障碍在智力障碍中起主要作用。思维迟缓及皮质下痴呆的概念似乎仍适用于定义帕金森病的认知障碍。
