为了评估痴呆的阶段，我们重点关注了脑电图节律和长谷川痴呆评定量表（HDS-R）。在音乐和图片刺激下，记录痴呆患者和正常对照者的额叶脑电图，并进行频率分析。在对照组中，音乐刺激期间的节律模式的配置文件似乎显着不同，在照片图像刺激。相比之下，在痴呆症患者中，很难找到这些差异。有趣的是，随着HDS-R降低，节律模式的变异性也降低。这些结果表明，认知功能的下降可能与产生各种皮质节律模式的能力下降有关。
In order to evaluate the stage of dementia, we focused attention on EEG rhythms and Hasegawa-dementia-rating scale (HDS-R). Frontal EEGs were recorded from dementia patients and normal controls during music and photo-image stimulations, and frequency analysis was performed. In the controls, profiles of rhythm pattern during music stimulation seemed to be markedly different from those during photo-image stimulation. In contrast, in dementia patients, it was difficult to find those differences. Interestingly, as HDS-R decreases, the variability of rhythm patterns also decreases. These results suggest that a decrease in cognitive function might be related to a decrease in the ability to generate various cortical rhythm patterns.
