汉英对照/痴呆症是由脑细胞受损引起的

痴呆症是由脑细胞受损引起的。 这种损害会干扰脑细胞相互交流的能力。 当脑细胞无法正常交流时，思维，行为和感觉都会受到影响。

Dementia is caused by damage to brain cells. This damage interferes with the ability of brain cells to communicate with each other. When brain cells cannot communicate normally, thinking, behavior, and feeling are all affected.
