What are the symptoms of brain disorders?

The symptoms of brain nerve structure damage can be divided into four groups according to their performance, namely ischemia, defect symptoms, stimulation symptoms, release symptoms and disconnection shock symptoms. First, ischemia symptoms, is the weakening or disappearance of normal functions when the nerve structure is damaged. Second, stimulation symptoms, is the excessive excitation caused by the nerve structure after stimulation, such as epilepsy caused by tumor and scar stimulation in the motor area of the cerebral cortex. 3. Release symptoms refer to hyperfunction of the lower central nervous system inhibited by the higher central nervous system after it is damaged. 4. Disconnection shock symptoms refer to temporary loss of nerve function in distant parts closely related to the damaged parts when acute and severe damage occurs locally in the central nervous system, including cerebral shock and spinal cord shock.
