There is no optimal solution for ataxia, and general treatment, medication, surgery, and rehabilitation should be taken for the disease, which can be caused by cerebral hemorrhage, cerebral infarction, and brain tumor. Ataxia is a symptom that occurs when the nerves controlling muscle coordination are damaged, degenerated or lose their function, and should be treated according to the disease. 1. Cerebral hemorrhage: Cerebral hemorrhage damages brain tissues and nerves, and middle cerebral hemorrhage can lead to ataxia of the same side of the limb. Mannitol and other drugs should be given to reduce cranial pressure by dehydration, and cytarabine and other drugs should be given to improve metabolism. For those with more serious bleeding, surgery should be carried out, and blood pressure, blood fat and blood sugar should be controlled at the same time. 2. Cerebral infarction: blood circulation disorder in the brain will lead to ischemia and hypoxia of brain tissues, resulting in limited tissue necrosis, affecting the neurological function, and ataxia can occur. Thrombolytic therapy such as alteplase should be used as soon as possible within 4.5h after the onset of the disease, and interventional therapy should be carried out when necessary. 3. Brain tumor: the tumor erodes brain tissue, brain nerves or presses into the local area, thus affecting the nerve function, and ataxia may appear, and the tumor can be removed by surgery, and radiotherapy and chemotherapy can be carried out after surgery. Patients with ataxia can also undergo rehabilitation training, such as coordination training and balance training. Family members can assist the patient in standing and walking to exercise balance; assigning the patient to draw a circle or placing a limb in a designated position to exercise coordination. Patients with ataxia should follow the doctor’s instructions after identifying the cause of the disorder and should not use drugs indiscriminately.
