Intracranial hypertension

Definition

Intracranial hypertension is a condition where the pressure inside the skull exceeds normal levels, often due to an increase in the volume of brain tissue, blood, or cerebrospinal fluid. It can lead to serious health issues if not managed promptly.

5 Must Know Facts For Your Next Test

1. Intracranial hypertension can result from head injury, infections, or tumors.
2. Symptoms include headache, nausea, vomiting, and visual disturbances.
3. Diagnosis often involves imaging studies like CT or MRI scans and measuring intracranial pressure (ICP).
4. Common treatments include medications like diuretics, corticosteroids, and anticonvulsants to manage symptoms and reduce pressure.
5. Severe cases might require surgical interventions such as ventriculostomy or decompressive craniectomy.
