Benign intracranial6
- Idiopathic intracranial hypertension (IIH), previously known as pseudotumor cerebri and benign intracranial hypertension, is a condition characterized by increased intracranial pressure (pressure around the brain) without a detectable cause. (wikipedia.org)
- Therefore, although imperfect, the term 'IIH' is currently the preferred designation for this disorder in the English literature, to the exclusion of 'pseudotumour cerebri' (often including patients with other causes of raised ICP such as cerebral venous thrombosis) and 'benign intracranial hypertension' (erroneously reassuring considering that a number of IIH patients irreversibly lose vision). (bmj.com)
- Thus, although IIH, pseudotumor cerebri, and benign intracranial hypertension (BIH) may be considered to be used interchangeably, IIH is the more precise term for the disease entity that is not linked to a secondary disorder. (medscape.com)
- The older term benign intracranial hypertension is generally frowned upon due to the fact that some patients with idiopathic intracranial hypertension have a fairly aggressive clinical picture with rapid visual loss. (radiopaedia.org)

(paediatricfoam.com)

- Your brain and spinal cord are surrounded by cerebrospinal fluid, which is produced in the brain and eventually is absorbed into the bloodstream at a rate that usually allows the pressure in your brain to remain constant. (uthealthaustin.org)
- If too much fluid is produced, or not enough is re-absorbed, the cerebrospinal fluid can build up and cause pressure within the skull. (uthealthaustin.org)
- Carbonic anhydrase inhibitors such as acetazolamide are believed to reduce the rate of cerebrospinal fluid production, and their use has been shown to have associated improvement in outcomes in patients with pseudotumor cerebri. (picmonic.com)
