Characteristics of NPH are gait disturbance, urinary incontinence, dementia, enlarged brain ventricles and a normal or slightly elevated CSF pressure.

It is believed that the normal pressure (arachnoid Granulationes) by a deficit in the Liquorresorption Arachnoidealzotten is caused. This disease accounts for up to 6% of the dementias; Dementia is a chronic, global, usually irreversible deterioration of cognition.

It is believed that the normal pressure (arachnoid Granulationes) by a deficit in the Liquorresorption Arachnoidealzotten is caused. This disease accounts for up to 6% of the dementias; Dementia is a chronic, global, usually irreversible deterioration of cognition. Dementia should not be confused with delirium although the perception is impaired in both. The following helps to distinguish these: Dementia mainly affects memory, is usually caused by anatomical changes in the brain shows a slow start and is usually irreversible. A Dellir mainly concerns the Aufnmerksamkeit, is usually caused by an acute illness or drug or drug toxicity (sometimes fatal) and is often reversible. Other characteristics also help to distinguish dementia and delirium (see Table s. Differences between delirium and dementia *). Symptoms and complaints The gait disturbance at normal pressure are usually non-specific fluctuation and balance disorders, although the magnetic transition (feet seem to stick to the ground) is considered characteristic gait disturbance. Dementia can occur in the disease process late. The most common early symptoms of dementia are disturbances in executive functioning and attention; the memory is impaired rather later. Urinary incontinence is common. Diagnosis Clinical evaluation Neuroimaging Liquorentnahme The classic symptoms (gait disturbance, urinary incontinence and dementia) are Sometimes, even in combination, non-specific for the normal pressure, especially in the elderly. Some forms of vascular dementia z can. As dementia, gait disturbance and, rarely, cause urinary incontinence. A general diagnosis of dementia requires each of the following: cognitive or behavioral (neuropsychiatric) symptoms that interfere with the ability to function at work and perform usual daily activities. These symptoms represent a decline of previous functional levels. These symptoms can be explained not by delirium or major mental disorder. To Abkl√§rungder cognitive function includes the recording of the patient’s medical history and by a person who knows the patient, plus an examination of the mental state at the bedside or if the investigation at the bedside remains inconclusive, formal neuropsychological examination (dementia: assessment of cognitive function). The imaging of the brain can be a ventricular enlargement, which is not proportional to the cortical atrophy; This finding is non-specific, but can support the diagnosis of normal pressure hydrocephalus. A spinal tap, in which 30 to 50 ml liquor are removed, can be performed for diagnostic purposes. An improvement of gait, continence and cognitive after removal helps to confirm the diagnosis, but the improvement may be evident until several hours after collection. Another Liquor can emerge after the lumbar puncture, which sometimes contributes to the improvement. Sometimes treatment ventriculoperitoneal shunt A ventriculoperitoneal shunt is useful in patients with acceptable surgical risk. An improvement by lumbar puncture with Liquorentnahme that occurs during the diagnosis may predict the response to the shunt. In several case series (but not in randomized trials) patients showed after placement of the shunt a substantial Bessserung, typically transition, continence and everyday functions; an improvement of cognition occurred less frequently.
