Does hypertension increase intracranial pressure?

Intracranial hypertension is a spectrum of neurological disorders where cerebrospinal fluid (CSF) pressure within the skull is elevated. Normal CSF pressure varies by age. In general, CSF pressure above 250 mm H20 in adults and above 200 mm H2O in children signifies increased intracranial pressure (ICP).
