Adams–Stokes syndrome, Stokes–Adams syndrome or Gerbec–Morgagni–Adams–Stokes syndrome is a periodic fainting spell in which there is intermittent complete heart block or other high-grade arrhythmia that results in loss of spontaneous circulation and inadequate blood flow to the brain. Subsequently, named after two Irish physicians ...
Cardiovascular. A Hollenhorst plaque (also known as a retinal cholesterol embolus) is a cholesterol embolus that is seen in a blood vessel of the retina. It is usually found when a physician performs ophthalmoscopy, during which a plaque will appear as a small, bright crystal that is refractile (reflects the light from the ophthalmoscope) and ...
Brain ischemia is a condition in which there is insufficient bloodflow to the brain to meet metabolic demand. [1] This leads to poor oxygen supply or cerebral hypoxia and thus leads to the death of brain tissue or cerebral infarction / ischemic stroke. [2] It is a sub-type of stroke along with subarachnoid hemorrhage and intracerebral hemorrhage.
The MCA is the most common site for the occurrence of ischemic stroke. [1] Depending upon the location and severity of the occlusion, signs and symptoms may vary within the population affected with MCA syndrome. More distal blockages tend to produce milder deficits due to more extensive branching of the artery and less ischemic response.
Lateral medullary syndrome is a neurological disorder causing a range of symptoms due to ischemia in the lateral part of the medulla oblongata in the brainstem. The ischemia is a result of a blockage most commonly in the vertebral artery or the posterior inferior cerebellar artery. [1] Lateral medullary syndrome is also called Wallenberg's ...
To determine the type and characteristics of a stroke, brain imaging is an essential part of the stroke patient evaluation process. The preferred imaging modality in this case is non-contrast computed tomography (CT) of the head. Depending on where they are or how big they are, anterior cerebral artery strokes may be overlooked on imaging tests.
Moyamoya disease is a disease in which certain arteries in the brain are constricted. Blood flow is blocked by constriction and blood clots (thrombosis). [ 2 ] A collateral circulation develops around the blocked vessels to compensate for the blockage, but the collateral vessels are small, weak, and prone to bleeding, aneurysm and thrombosis.
Cerebral infarction. Cerebral infarct. Specialty. Neurology. Cerebral infarction, also known as an ischemic stroke, is the pathologic process that results in an area of necrotic tissue in the brain (cerebral infarct). [1] In mid to high income countries, a stroke is the main reason for disability among people and the 2nd cause of death. [2]
