Traumatic brain injury: pathophysiology for neurocritical care?

WebJan 1, 1998 · Background—Cerebral blood flow is tightly coupled to neuronal metabolic activity, a phenomenon referred to as functional hyperemia.The mechanisms underlying functional hyperemia in the brain have been extensively studied, but the link between neuronal activation and nutritive blood flow has yet to be defined. WebDec 1, 2024 · Explanations for potential mechanisms include cerebral ischemia, increased intracranial pressure, cortical spreading depressions, and activation of trigeminovascular nerve afferents. 12 In case of AVMs with TDBS, meningeal irritation or cerebral hyperemia, due to additional ECA blood shunt volume, is likewise conceivable. 3 bedroom apartment for sale toronto WebA brain metastasis is a cancer that has metastasized (spread) to the brain from another location in the body and is therefore considered a secondary brain tumor.
