Cerebellar atrophy cannot be treated by doing surgery. Patients with cerebellar atrophy may show inflexibility of limbs and unstable gait. Patients with cerebellar atrophy should quit smoking, quit drinking, and develop good habits, as well as avoid using drugs that can damage brain tissue. Patients should keep a calm state of mind, exercise moderately, and take drugs to improve ataxia, which can improve the patient’s symptoms. In conclusion, the treatment of microcephaly is comprehensive and diversified. If patients have unstable walking and limb balance disorders, they can do rehabilitation training for motor function. In terms of diet, patients are advised to eat more light, nutrient-rich food, to eat less spicy and stimulating food, mainly a diet high in protein and vitamins, and drugs can be given to patients to improve brain metabolism with Olanzapine.
