benign intracranial hypertension

A syndrome of raised pressure within the skull in the absence of a brain tumour, HYDROCEPHALUS or other obvious cause. The condition is only relatively benign as it often leads to visual loss from compression damage to the optic nerves. It occurs most often in women below the age of 40 and causes severe headache and nausea but no deterioration of intellect or consciousness. Obesity is a common association. Ophthalmoscopic examination shows striking swelling of the optic discs (papilloedema).
