< 汉英对照
归类为“痴呆”的疾病是由异常的大脑变化引起的。 这些变化导致思维能力下降，即认知能力下降，严重到足以损害日常生活和独立功能。 它们还会影响行为，感觉和人际关系。
Diseases classified as "dementia" are caused by abnormal brain changes. These changes lead to a decline in thinking ability, that is, cognitive decline, which is severe enough to impair daily life and independent functions. They also affect behavior, feelings and relationships.
