When people get older, their bodies are always prone to various problems. For example, hypertension, diabetes, cerebral infarction, hydrocephalus, etc.. We are familiar with the first three diseases because we often encounter them in our lives, but when it comes to hydrocephalus, many people still have a lot of confusion. Hydrocephalus, an easy-to-understand term, mainly refers to a circulatory disorder of the cerebrospinal fluid that leads to progressive dilation of the ventricular system or expansion of the subarachnoid space, which produces a series of symptoms in the human body. For example, some people experience headaches, decreased calculation power, and slow reactions; some people experience incontinence and progressive dementia; and some elderly people experience unstable walking and fall easily. The elderly are also a major group of people with hydrocephalus, but most of them have normal pressure hydrocephalus, which has a distinctive feature: although the ventricles are enlarged, there is hardly any change in cerebrospinal fluid pressure. Therefore, when an elderly person has the above mentioned condition, it is recommended to go to the hospital for detailed diagnosis and if the diagnosis of normal pressure hydrocephalus is confirmed, surgery is recommended in a timely manner. When it comes to surgery, many elderly people with normal pressure hydrocephalus are more or less afraid of it because after all, it is an open surgery. Even if they can tolerate the pain, the safety of the surgery is still a cause for concern. In fact, nowadays, medicine is very advanced, shunt surgery as a routine operation for the treatment of hydrocephalus, such as large hospitals in the north, operated by senior experts with pure technology, the operation is relatively safe, the risk is not high, it is recommended that patients go to large hospitals to perform surgical operations in a timely manner.
