The functions of the human body will decline with age, especially the elderly, most of them will have unstable walking and fall easily when they get older, if this situation is transient, then do not worry too much. If you fall up and down the stairs frequently, you need to be alert because these symptoms are most likely a hint of some disease coming. So, what causes the elderly to walk unsteadily and fall easily? There are many causes of unstable walking in the elderly, and the clinical analysis should be combined with the patient’s underlying disease, the urgency of the onset and the accompanying symptoms. If the onset of the disease is sudden, it is generally considered to be caused by cerebrovascular diseases, such as cerebral infarction and cerebral hemorrhage. If the onset is chronic, intracranial tumors, intracranial occupancies, Parkinson’s syndrome and other diseases should be considered. In addition, if walking is unstable, with smaller and smaller steps, slower and slower speed, frequent falls and stiffness of limbs, this condition should also be considered normal pressure hydrocephalus. Normal pressure hydrocephalus is a group of clinical syndromes in which the ventricles are enlarged on imaging and the cerebrospinal fluid pressure is measured within the normal range. It is usually seen in elderly people over 65 years of age and may manifest as cognitive dysfunction and urinary incontinence in addition to gait disturbances. In addition, patients also have some non-specific symptoms, such as headache, dizziness, prolonged sleep, Parkinson’s-like tremor and sexual dysfunction. Of course, for patients with the above symptoms, they cannot be completely judged as normal pressure hydrocephalus, and a definite diagnosis can be made only with the help of some advanced imaging equipment and according to the displayed results. Cranial CT and MRI are two common auxiliary examination devices for normal pressure hydrocephalus, which can provide accurate basis for clinical diagnosis and treatment. At present, there is a set of special techniques of cerebrospinal fluid department in the clinic to develop individualized treatment plan for each hydrocephalus patient. For elderly people who walk unsteadily and fall easily, patients can recover to normal after scientific treatment.
