Hypertension, blood-brain barrier disruption and changes in intracranial pressure.

ABSTRACT: Intracranial pressure (ICP) is pressure within the cranium, between 5 and 15 mmHg in a normal brain, and is influenced by the dynamic balance between brain tissue, cerebrospinal fluid (CSF) and cerebral blood volume. ICP is vital for cerebral health, impacting outcomes in various neurological conditions. Disruptions, such as cerebral haemorrhage, hydrocephalus and malignant hypertension, can lead to elevated ICP, a dangerous condition known as intracranial hypertension (IH). Systemic hypertension significantly impacts cerebral health by causing microvascular damage, dysfunction of the blood-brain barrier (BBB) and impairment of intracranial compliance (ICC). This increases the risk of IH), cerebral ischaemia, neuroinflammation and lacunar infarction, further worsening neurological dysfunct
