The clinical triad of normal pressure hydrocephalus (NPH), a condition that affects the elderly and is identified by ventriculomegaly and deep white matter ischemia (DWMI) on magnetic resonance imaging, includes gait disturbance, dementia, and urinary incontinence (MRI). The differential diagnosis of neurological diseases must include it as a key factor. The frequency of dementia is increasing in line with the rise in life expectancy worldwide. The pathophysiology of NPH is still a topic of debate. Although guidelines and recommendations for best practices are well established, there is an ongoing debate on the use of various imaging modalities to pinpoint specific symptoms of the illness and predict how effective CSF shunting will be. Despite the development of diagnostic methods, treatment approaches, and more than 50 years of study, NPH remains a problem for experts. Although we should differentiate between sNPH and iNPH based on the result as well as the clinical, pathophysiological, and epidemiological aspects, they shouldn't be seen as separate entities. The patient's medical history, neurological examination, and brain imaging are still used to make the diagnosis in both kinds of NPH. Ventriculoperitoneal and ventriculoatrial shunts are two of the most common CSF shunt procedures.
