Idiopathic intracranial hypertension
Idiopathic Intracranial Hypertension (Pronunciation: /ˌɪdiəˈpæθɪk ˌɪntrəkrəˈniːəl haɪpərˈtɛnʃən/), also known as IIH or pseudotumor cerebri, is a neurological disorder characterized by increased intracranial pressure (pressure around the brain) without a detectable cause. The name is derived from the Greek words idiopathes ("arising spontaneously or from an obscure or unknown cause") and hypertension ("abnormally high blood pressure").
Definition
Idiopathic intracranial hypertension is a condition of unknown etiology, characterized by increased intracranial pressure, without the presence of tumor or other diseases affecting the brain or its lining. Diagnosis requires brain scans and lumbar puncture.
Symptoms
Common symptoms include headache, double vision (diplopia), pulsatile tinnitus (a whooshing sound in the ears), and visual problems such as blurred vision, blind spots, and vision loss.
Treatment
Treatment often involves medication to decrease cerebrospinal fluid production and reduce intracranial pressure. In some cases, surgical procedures may be necessary.
Epidemiology
IIH primarily affects obese women of childbearing age, but it can occur in patients of any weight, sex, and age.
