Letter to our colleagues Family Practitioners, Geriatricians, and Radiologists to increase awareness regarding idiopathic Normal Pressure Hydrocephalus (iNPH).

Idiopathic Normal Pressure Hydrocephalus (iNPH) is an underdiagnosed cause of dementia-like symptoms. The Primary Care Provider (PCP) and/or the Geriatrician can significantly improve iNPH diagnosis by requesting the Radiologist to measure the callosal angle on the Computed Tomography (CT) of their patients with cognitive impairment also affected by gait/balance difficulties. Increasing the recognition of iNPH patients is important because surgery benefits these patients even when there is co-existing early Alzheimer's Dementia (AD) or other related dementias.
