What is normal pressure hydrocephalus in the elderly? There are many clinical classifications of hydrocephalus. Traffic hydrocephalus is one of the more common ones, which is characterized by the absence of significant obstruction in various parts of the cerebrospinal fluid circulation pathway and basically normal cerebrospinal fluid pressure. Normal pressure hydrocephalus is a syndrome of traffic hydrocephalus in which the ventricles are enlarged and the cerebrospinal fluid pressure does not change. The incidence of normal pressure hydrocephalus is concentrated in the elderly population over 65 years of age. Incidence of normal pressure hydrocephalus Because of the late start of research work on normal pressure hydrocephalus in China, the incidence of the disease is still unclear up to now. In contrast, European and American countries as well as Japan have studied normal pressure hydrocephalus earlier and paid more attention to it, and have made great gains in terms of relevant data. According to relevant data, the probability of normal pressure hydrocephalus in elderly people over 80 years old in Sweden is about 5%, and from this data, almost one out of every 20 elderly people suffers from this disease, and the incidence is still very high. Normal pressure hydrocephalus hazards Many senior experts in neurosurgery have studied, practiced and summarized a large number of clinical cases, and finally gave a clear conclusion that normal pressure hydrocephalus usually has three main characteristics, namely, limb impairment, cognitive impairment and urinary impairment. For example, some patients often walk unsteadily and fall down easily. Some patients are unresponsive, have decreased calculation power, anxiety and depression, and some patients have frequent and urgent urination in the early stage and urinary incontinence in the later stage. To sum up, normal pressure hydrocephalus has a great impact on our physical, mental and psychological aspects. Normal pressure hydrocephalus is reversible in most cases, which is full of hope for patients. Early detection and timely surgical treatment can result in a very high recovery rate. Currently, we have a unique set of specialized techniques for each type of hydrocephalus, and we have targeted treatment techniques and protocols for each type of hydrocephalus, with good postoperative recovery.
