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]
Symptoms may include severe headache, visual symptoms, any of the symptoms of stroke such as weakness of the face and limbs on one side of the body, and seizures, which occur in around 40% of patients. [2] The diagnosis is usually by computed tomography (CT scan) or magnetic resonance imaging (MRI) to demonstrate obstruction of the venous ...
Other common symptoms are a pulsing noise in the head, progressive weakness, numbness and vision changes as well as debilitating, excruciating pain. [4] [5] In serious cases, blood vessels rupture and cause bleeding within the brain (intracranial hemorrhage). [a] In more than half of patients with AVM, this is the first symptom. [7]
Cerebral vasospasm is the prolonged, intense vasoconstriction of the larger conducting arteries in the subarachnoid space which is initially surrounded by a clot.Significant narrowing of the blood vessels in the brain develops gradually over the first few days after the aneurysmal rupture.
The underlying mechanism involves inflammation of the small blood vessels that supply the walls of larger arteries. [4] This mainly affects arteries around the head and neck, though some in the chest may also be affected. [4] [8] Diagnosis is suspected based on symptoms, blood tests, and medical imaging, and confirmed by biopsy of the temporal ...
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]
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]
