The cerebral blood volume maps can be calculated by dynamic magnetic resonance image set obtained by echo planar imaging after intravenous injection of thiol contrast agent. [7] Planar imaging techniques or single high-speed shots provide the necessary resolution for contrast agents to display rapid brain blood movements. [8]
Cerebral atrophy can be hard to distinguish from hydrocephalus because both cerebral atrophy and hydrocephalus involve an increase in cerebrospinal fluid (CSF) volume. In cerebral atrophy, this increase in CSF volume comes as a result of the decrease in cortical volume. In hydrocephalus, the increase in volume happens due to the CSF itself. [20]
The most common, most controllable lifestyle behaviors—dubbed Life’s Essential 8 cardiovascular health metrics by the Stroke Association—will, when left unchecked, become factors that are ...
Hemorrhagic stroke may occur on the background of alterations to the blood vessels in the brain, such as cerebral arteriolosclerosis, cerebral amyloid angiopathy, cerebral arteriovenous malformation, brain trauma, brain tumors and an intracranial aneurysm, which can cause intraparenchymal or subarachnoid hemorrhage.
End organ damage is severe impairment of major body organs due to systemic disease. Commonly this is referred to in diabetes, high blood pressure, or states of low blood pressure or low blood volume. [1] This can present as a heart attack or heart failure, pulmonary edema, neurologic deficits including a stroke, or acute kidney failure. [2]
Ischemia is a vascular disease involving an interruption in the arterial blood supply to a tissue, organ, or extremity that, if untreated, can lead to tissue death. It can be caused by embolism, thrombosis of an atherosclerotic artery, or trauma. Venous problems like venous outflow obstruction and low-flow states can cause acute arterial ischemia.
The condition is usually due to an insult to the dominant hemisphere of the brain. More often this is located in the frontal lobe of the left hemisphere of the brain. Treatment of acquired apraxia due to stroke usually consists of physical, occupational, and speech therapy.
Life expectancy can vary greatly depending on a person's sex and race. American Indian and Alaska Native males had the lowest life expectancy at 64.6 years, while Asian females had the highest ...
