An obstruction of an artery in the brain.
Gross cerebral hemorrhage or softening of the brain following hemorrhage, thrombosis, or embolism of the cerebral arteries. Symptoms may include coma, paralysis (particularly on one side of the body), convulsions, aphasia, and other neurological signs determined by the location of the lesion.
Also known as cerebrovascular accident (CVA); damage to brain tissue by hypoxia due to blockage of a blood vessel as a result of thrombosis, atherosclerosis or haemorrhage.
Cerebrovascular accident (CVA); gross cerebral hemorrhage or softening of the brain following hemorrhage, thrombosis, or embolism of the cerebral arteries. Symptoms may include coma, paralysis (particularly on one side of the body), convulsions, aphasia, and other neurological signs determined by the location of the lesion.
A hemorrhage or a blockage in a blood vessel extending to the brain, resulting in insufficient delivery of blood (and therefore oxygen) to a portion of the brain. Many strokes can result in some degree of paralysis, but small strokes may occur without symptoms. Recurrent strokes can lead to mental deterioration.
Sudden brain injury due to inadequate blood supply, resulting from a blocked artery or hemorrhage due to a ruptured artery. Brain damage may be large or minimal following a small temporary blockage such as a TIA (transient ischemic attack, a “ministroke”).
A cerebral accident.
Blockage or rupture of blood vessel(s) supplying the brain resulting in loss of consciousness, paralysis, and other symptoms. Apoplexy is a common term for stroke.
Damage to part of the brain caused by an interruption to its blood supply or leakage of blood outside of vessel walls.
A sudden attack of weakness or paralysis, usually affecting one side of the body. It is the consequence of an interruption to the flow of blood to the brain. The primary disease is in the heart or blood vessels and the effect on the brain is secondary. The flow of blood may be prevented by clotting (thrombosis), a detached clot that lodges in an artery (embolus), or rupture of an artery wall (hemorrhage). A stroke can vary in severity from a passing weakness or tingling in a limb to a profound paralysis, coma, and death.
Stroke, or cerebrovascular accident (CVA), is sudden damage to brain tissue caused either by a lack of blood supply or rupture of a blood vessel. The affected brain cells die and the parts of the body they control, or receive sensory messages from, cease to function. Each year, about 150,000 people in the UK have a stroke, most of whom are aged over 65.
Stroke occurs when blood flow to the brain is blocked. It is primarily caused by atherosclerosis.
A sudden attack of weakness or paralysis that occurs when blood flow to an area of the brain is interrupted.
Cerebral infarction refers to the permanent impairment of brain function due to inadequate blood flow caused by the blockage of an artery. This condition can lead to various forms of damage, including speech or vision loss, paralysis, cognitive decline, and even mortality.
Injury to a section of the brain occurs when its blood supply is disrupted. The primary factor behind this occurrence is the obstruction of a cerebral artery by a blood clot, which could originate within the artery itself or be transported through the bloodstream from another body area. Additionally, a stroke can arise from a confined instance of bleeding caused by the rupture of a blood vessel, which could involve an aneurysm or a bleeding disorder, either within the brain or in close proximity to it.
The likelihood of experiencing a stroke becomes more prominent as age advances, and it is more prevalent among men. Various factors contribute to an elevated risk, with hypertension and atherosclerosis being the most significant ones, as they harm the walls of arteries. Smoking intensifies the risk of stroke by amplifying the susceptibility to all these ailments. Moreover, diabetes escalates the likelihood of atherosclerosis. Conditions like atrial fibrillation (irregular and rapid heartbeats), a compromised heart valve, or a recent heart attack can result in the formation of clots in the heart, which may subsequently travel to the brain.
Symptoms typically emerge suddenly and vary based on the location, cause, and scope of the brain injury. Impairment occurs in the movement, functionality, or sensation governed by the affected brain region. Potential complications of a significant stroke encompass pneumonia and blood clot formation in the legs, which could potentially result in a pulmonary embolism. Approximately one-third of major strokes result in fatality, another third lead to varying degrees of disability, while the remaining one-third result in no enduring negative consequences.
Various methods can be employed to examine the origin and magnitude of brain injury. These encompass ECG, CT scans, chest X-rays, blood tests (which might encompass clotting assessments), angiography, MRI, and carotid Doppler scanning (used to evaluate constriction in the carotid artery).
For certain instances of stroke, prompt intervention can enhance the prospects of recuperation. When a scan indicates that the stroke arises from thrombosis, thrombolytic medications might be administered to dissolve the clot. Anticoagulants could be prescribed in cases where a clear embolism source exists, like atrial fibrillation. To deter additional clotting, antiplatelet agents such as aspirin may be employed.
Giving heed to proper hydration and managing pressure points, along with providing attentive nursing care, significantly impact the eventual results. Physiotherapy has the potential to recover lost mobility or sensation, while speech therapy can assist in addressing language impairments.
A sudden intense onset, as seen in conditions like paralysis or sunstroke; a brain event where a blood vessel ruptures, leading to bleeding inside the skull.
