Pediatric stroke is a stroke that occurs in children or adolescents. Stroke affects an estimated 2.5 to 13 per 100,000 children annually. [1] The signs and symptoms of stroke in children, infants, and newborns are different from those in adults. The causes and risk factors of stroke in children are also different from those in adults. [2]
In children, the most common cause is a stroke of the ventral pons. [9]Unlike persistent vegetative state, in which the upper portions of the brain are damaged and the lower portions are spared, locked-in syndrome is essentially the opposite, caused by damage to specific portions of the lower brain and brainstem, with no damage to the upper brain.
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]
Stroke affecting large portions of the brain can cause significant brain swelling with secondary brain injury in surrounding tissue. This phenomenon is mainly encountered in stroke affecting brain tissue dependent upon the middle cerebral artery for blood supply and is also called "malignant cerebral infarction" because it carries a dismal ...
Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
Symptoms of a brainstem stroke frequently include sudden vertigo and ataxia, with or without weakness. Brainstem stroke can also cause diplopia, slurred speech and decreased level of consciousness. A more serious outcome is locked-in syndrome. [citation needed]
Neonatal stroke, similar to a stroke which occurs in adults, is defined as a disturbance to the blood supply of the developing brain in the first 28 days of life. [1] This description includes both ischemic events, which results from a blockage of vessels, and hypoxic events, which results from a lack of oxygen to the brain tissue, as well as some combination of the two.
Encephalopathy is a difficult term because it can be used to denote either a disease or finding (i.e., an observable sign in a person). [citation needed] When referring to a finding, encephalopathy refers to permanent (or degenerative) [11] brain injury, or a reversible one. It can be due to direct injury to the brain, or illness remote from ...
