脑是人体最为重要的器官。大脑是个高度发达的特殊器官,功能复杂,人体的各种活动中枢,包括视觉、听觉、味觉、嗅觉、内脏、平衡、运动、语言等中枢都分布于大脑皮层。如果大脑功能受损,就会发生某个中枢的功能障碍,出现不同的临床症状。因此加强老年人脑功能保护非常必要。 The brain is the body’s most important organ. The brain is a highly developed and special organ with complex functions. The various central organs of the human body, including vision, hearing, taste, smell, viscera, balance, exercise and language, are all distributed in the cerebral cortex. If brain function is impaired, a central dysfunction occurs and different clinical symptoms occur. Therefore, it is very necessary to strengthen the protection of brain function in the elderly.
