Japan is experiencing an increase in the number of patients with dementia, and the incidence of epilepsy is high among the elderly. A survey of patients with epilepsy who were admitted to our hospital's neurology department showed that new onset epilepsy occurred more frequently in elderly patients. In addition, a greater proportion of elderly patients had dementia as an underlying disease. Although the prevalence of epilepsy in dementia varies, higher brain dysfunctions are known to be related to epilepsy. Because a symptom of epilepsy may be mistaken for dementia, it is important to understand the association between epilepsy and dementia, including their tendencies and characteristics.
日本痴呆症患者数量正在增加，且老年人中癫痫发病率较高。对我院神经内科收治的癫痫患者进行的一项调查显示，新发癫痫在老年患者中更为常见。此外，更大比例的老年患者患有痴呆症这一基础疾病。尽管痴呆症中癫痫的患病率各不相同，但已知较高的脑功能障碍与癫痫有关。由于癫痫症状可能被误诊为痴呆症，了解癫痫与痴呆症之间的关联，包括它们的倾向和特征非常重要。
