Cerebral vasculitis (sometimes the word angiitis is used instead of "vasculitis") is vasculitis (inflammation of the blood vessel wall) involving the brain and occasionally the spinal cord. [1] It affects all of the vessels: very small blood vessels ( capillaries ), medium-size blood vessels ( arterioles and venules ), or large blood vessels ...
Reversible cerebral vasoconstriction syndrome (RCVS, sometimes called Call-Fleming syndrome) is a disease characterized by a weeks-long course of thunderclap headaches, sometimes focal neurologic signs, and occasionally seizures. [1] Symptoms are thought to arise from transient abnormalities in the blood vessels of the brain. [1]
Public knowledge of stroke symptoms is scarce, with only 17.2% of people being able to correctly identify an individual experiencing a stroke. [11] Cerebral ischaemia refers to a severely reduced flow of blood in the brain due to narrowing or blocking of arteries or blood vessels causing inflammation. [12]
An intracranial aneurysm, also known as a cerebral aneurysm, is a cerebrovascular disorder characterized by a localized dilation or ballooning of a blood vessel in the brain due to a weakness in the vessel wall. These aneurysms can occur in any part of the brain but are most commonly found in the arteries of the cerebral arterial circle. The ...
Often, patients can only recognize their prodrome symptoms when they get to the pain phase and look back, Singh says. During a prodrome period, the Mayo Clinic and American Migraine Foundation say ...
Atherosclerosis narrows blood vessels in the brain, resulting in decreased cerebral perfusion. Other risk factors that contribute to stroke include smoking and diabetes. [6] Narrowed cerebral arteries can lead to ischemic stroke, but continually elevated blood pressure can also cause tearing of vessels, leading to a hemorrhagic stroke. [4]
A blood clot that reaches your brain can cause a stroke. Symptoms of a stroke include sudden: Numbness or weakness, often on one side of your body or face. Confusion. Trouble seeing in one or both ...
Any blood clot forms due to an imbalance between coagulation (the formation of the insoluble blood protein fibrin) and fibrinolysis. The three major mechanisms for such an imbalance are enumerated in Virchow's triad: alterations in normal blood flow, injury to the blood vessel wall, and alterations in the constitution of blood (hypercoagulability).
