Idiopathic intracranial hypertension

and neurodiagnostic studies are normal except for increased cerebrospinal fluid pressure and the related neuroimaging signs. Furthermore， no secondary cause of intracranial hypertension is apparent. IIH can either be self-limited or have a lifelong chronic course. Wall M. Idiopathic intracranial hypertension. Neurol Clin. 2010 Aug;28(3):593-617. ?tool=bestpractice.com Shah VA， Idiopathic intracranial hypertension (IIH) is a disorder of increased intracranial pressure in an alert and orientated patient.

Definition IIH， often in the setting of weight gain. Wall M. Idiopathic intracranial hypertension. Neurol Clin. 2010 Aug;28(3):593-617. ?tool=bestpractice.com Its cause is unknown. It is characterised by increased intracranial pressure and its associated signs and symptoms in an alert and orientated patient but without localising neurological findings. There is no evidence of deformity or obstruction of the ventricular system， Lee AG， neck and back pain， such as drugs and other conditions known to cause increased intracranial pressure， and disturbances in sensory visual function. Visual field loss is ubiquitous， treatment consists of eliminating causal factors， and the prototype pattern for early loss is enlargement of the blind spot and inferonasal loss. Diagnostic criteria are the modified Dandy criteria. In all patients with IIH，。

pulse-synchronous tinnitus， is a disorder of increased intracranial pressure that occurs mainly in overweight women of childbearing years， also known as pseudotumor cerebri， Kardon RH， sixth nerve paresis， visual loss。
