Normal pressure hydrocephalus is a condition that occurs in older adults over 65 years of age, often after cranial injury or subarachnoid hemorrhage or debridement, and is usually seen as a significant enlargement of the ventricular system on CT imaging. The causes of normal pressure hydrocephalus are classified as idiopathic or secondary. The causes of idiopathic hydrocephalus are generally not very clear and may be related to occult subarachnoid hemorrhage (SAH) or meningeal infection, while the causes of secondary hydrocephalus are clearer and most patients suffer from cerebrospinal meningitis, traumatic brain injury, brain tumors, and other factors. What are the initial symptoms of normal pressure hydrocephalus? It has been found that there are three main manifestations of normal pressure hydrocephalus, which are often referred to as the “three main signs”. The first is mental impairment, memory disorientation, and intellectual impairment. The second is gait disorder, which usually occurs several months after the onset of psychiatric symptoms, with mild patients having slow gait and difficulty walking in a straight line, and severe patients unable to walk and stand on their own and often falling down. When the first two main signs appear and are not treated in time, as the condition worsens, it can lead to serious consequences of uncontrollable urination and defecation, can normal pressure hydrocephalus be reversed by early treatment? It is well known that hydrocephalus is a danger to people that cannot be ignored. The discovery of hydrocephalus should be dealt with actively, and if it is not dealt with in a timely manner it can cause certain harm. So, can normal pressure hydrocephalus be reversed by early treatment? In the field of modern medicine, early diagnosis of any kind of disease is important, and normal pressure hydrocephalus is no exception, early detection and early intervention and treatment, reversibility is still great. Clinical observations have shown that many patients with gait instability and cognitive impairment have significantly improved after receiving surgical treatment. In contrast, those patients who miss the golden period of surgery may be bedridden for a long time, or even disabled or killed. What type of surgery is performed for normal pressure hydrocephalus? Ventriculoperitoneal shunt is a common technique for treating hydrocephalus and is usually performed in local hospitals in all major provinces. However, in terms of late follow-up results, patients often suffer from many complications after this procedure, such as the occurrence of infection or blockage of the shunt tube. After modification and upgrading, the traditional ventriculoperitoneal shunt has now been developed into a new ventriculoperitoneal shunt, which is not only effective in treating hydrocephalus, but also well suited to avoid the previous problems.
