Variation in blood pressure that is significantly greater than the norm is known as labile hypertension and is associated with increased risk of cardiovascular disease [63] brain small vessel disease, [64] and dementia [65] independent of the average blood pressure level.
[10] [13] Too much blood (a clinical condition of a normal homeostatic response of hyperemia) [1] can raise intracranial pressure (ICP), which can compress and damage delicate brain tissue. Too little blood flow results if blood flow to the brain is below 18 to 20 ml per 100 g per minute, and tissue death occurs if flow dips below 8 to 10 ml ...
An increase in pressure, most commonly due to head injury leading to intracranial hematoma or cerebral edema, can crush brain tissue, shift brain structures, contribute to hydrocephalus, cause brain herniation, and restrict blood supply to the brain. [13] It is a cause of reflex bradycardia. [14]
Impaired brain function. Unmanaged stress can impair memory, attention, and decision-making. ... High blood pressure (hypertension) Type 2 diabetes. Cardiovascular disease. Some cancers.
As we age, our hair may turn gray and smile lines may set in. And our brains will shrink (really!). Blame it on cognitive aging. “Cognitive aging is a natural, gradual change that occurs as we ...
This is opposite to carbon dioxide in tissues causing vasodilatation, especially in the brain. [2] Cranial nerves IX (glossopharyngeal nerve) and X (vagus nerve) both feed into the vasomotor centre and are themselves involved in the regulation of blood pressure.
