Generally speaking, most normal healthy elderly people, whether they are 60, 70 or even 80 years old, generally walk normally and do not fall down easily. However, there are some elderly people who were originally physically hardy, but without any signs and symptoms, they have trouble with their legs or feel that they are walking significantly slower than before, and they go to the hospital for examination and are diagnosed with normal pressure hydrocephalus. In response, many patients with similar symptoms began to wonder if they also had normal pressure hydrocephalus. So, is it normal pressure hydrocephalus that the elderly often fall down inexplicably? Chen Hongwei, director of the cerebrospinal fluid department of the General Hospital of Aviation of China Medical University, said that the elderly often fall inexplicably may not necessarily be normal pressure hydrocephalus, but there are many clinical causes for the elderly to fall. Normal pressure hydrocephalus and other diseases caused by gait disorders have obvious differences, patients suffering from this disease generally no problems with the upper limbs, stretching arms are strong, lying in bed legs can also move freely. Once they get out of bed, both lower limbs appear to be particularly weak, walking unsteadily and often falling. In this case, we should pay great attention to the situation, and must go to the hospital in time for examination. The examination method is also relatively simple, just need to do a head CT to see if the ventricles have been enlarged can be. According to research, people over 65 years old are the main group of people suffering from normal pressure hydrocephalus. In addition to obvious walking and falling, they may also show a serious loss of memory and calculation power, and serious cases are accompanied by frequent urination. In view of the fact that traditional shunt surgery is prone to blockage and infection, many experts and scholars in the medical field, with their tireless eternal perseverance and pioneering and innovative spirit of seeking, have continuously upgraded and transformed this surgical treatment, and developed a set of special techniques, which can achieve accurate diagnosis and treatment of normal pressure hydrocephalus, and the situation that the elderly often fall can be significantly improved after surgery.
