Hydrocephalus in the elderly is a relatively serious matter that must be detected and treated as early as possible. Many elderly people with hydrocephalus tend to gradually develop a series of clinical symptoms such as urinary and fecal incontinence, unstable walking, ataxia, etc. The majority of patients are unlikely to be treated well with subsequent medication, and many have to be treated through surgical procedures. If surgery is not performed in a timely manner, hydrocephalus will have an increasing impact on the brain tissue and gradually produce changes in consciousness, such as drowsiness, lethargy, and even coma. If this is not corrected in time at a later stage, it may result in the death of the patient. At present, hydrocephalus in the elderly has a very good clinical prognosis as long as the cause is detected early and the solution is carried out early.
