Patients with cerebellar hypoperfusion may experience symptoms such as vertigo, nausea, and vomiting, as well as balance disorders, unsteady walking, and ataxia. The primary role of the cerebellum is to control the body’s balance and motor functions. When there is insufficient blood supply to the cerebellum, the patient’s motor function will be affected. Symptoms such as unsteady walking, ataxia, abnormal mental awareness, inability to point to the nose, inability to perform fine movements, and motor nerve function, sensory function, and balance dysfunction are common in the clinic. When cerebral blood supply insufficiency occurs, it is recommended that patients go to the Department of Cardiovascular and Cerebrovascular Medicine of the hospital as soon as possible, and exclude the possibility of other organic pathologies through cervical spine X-ray examination, cerebrospinal fluid examination, cranial magnetic resonance examination, and so on.
