Apathy, defined as decreased goal-directed activity, has been observed in Parkinson's disease. A number of cognitive/psychiatric features have been documented in essential tremor, yet we are unaware of studies of apathy.
Using the Apathy Evaluation Scale (range = 18-72 [more apathy]), we compared 79 essential tremor cases, 20 dystonia cases, and 39 Parkinson's disease cases with 80 normal controls.
The score of the Apathy Evaluation Scale was higher in essential tremor, dystonia, and Parkinson's disease cases than controls (all P ≤ .04). Parkinson's disease cases had the highest scores. Analyses stratified by presence/absence of depressive symptoms indicated the presence of a group of apathetic but nondepressed cases.
Patients with Parkinson's disease, essential tremor, and dystonia had elevated apathy scores. Features of apathy seemed to occur in these conditions independent of depressive symptoms. The mechanistic basis for the apparent increased features of apathy in essential tremor and dystonia deserves further study.
在帕金森病中观察到了冷漠,即目标导向活动减少。特发性震颤已记录了许多认知/精神特征,但我们不知道对冷漠的研究。
使用淡漠评估量表(范围为 18-72 [更多冷漠]),我们比较了 79 例特发性震颤病例、20 例肌张力障碍病例和 39 例帕金森病病例与 80 例正常对照组。
特发性震颤、肌张力障碍和帕金森病患者的淡漠评估量表评分高于对照组(均 P ≤.04)。帕金森病患者的评分最高。按是否存在抑郁症状进行分层分析表明,存在一组淡漠但不抑郁的病例。
帕金森病、特发性震颤和肌张力障碍患者的淡漠评分升高。这些疾病中似乎存在与抑郁症状无关的冷漠特征。特发性震颤和肌张力障碍中明显增加的冷漠特征的机制基础值得进一步研究。
