MeSH

A group of pathological conditions characterized by sudden, non-convulsive loss of neurological function due to BRAIN ISCHEMIA or INTRACRANIAL HEMORRHAGES. Stroke is classified by the type of tissue NECROSIS, such as the anatomic location, vasculature involved, etiology, age of the affected individual, and hemorrhagic vs. non-hemorrhagic nature. (From Adams et al., Principles of Neurology, 6th ed, pp777-810)

Year introduced: 2008 (2000)

Stroke caused by lacunar infarction or other small vessel diseases of the brain. It features hemiparesis (see PARESIS), hemisensory, or hemisensory motor loss.

Year introduced: 2012

Component of the NATIONAL INSTITUTES OF HEALTH. It supports and conducts research, both basic and clinical, on the normal and diseases nervous system. It was established in 1950.

Year introduced: 2018(2009)

A condition caused by the failure of body to dissipate heat in an excessively hot environment or during PHYSICAL EXERTION in a hot environment. Contrast to HEAT EXHAUSTION, the body temperature in heat stroke patient is dangerously high with red, hot skin accompanied by DELUSIONS; CONVULSIONS; or COMA. It can be a life-threatening emergency and is most common in infants and the elderly.

Year introduced: 1996

The amount of BLOOD pumped out of the HEART per beat, not to be confused with cardiac output (volume/time). It is calculated as the difference between the end-diastolic volume and the end-systolic volume.

Year introduced: 1986(1979)

Stroke due to rupture of a weakened blood vessel in the brain (e.g., CEREBRAL HEMISPHERES; CEREBELLUM; SUBARACHNOID SPACE).

Year introduced: 2021

An ischemic stroke due to a blood clot, emboli or other types of blockage which forms somewhere other than the brain and subsequently travels near and restricts blood flow to the brain. Most often the origin of the clot is from the heart and is referred to as cardioembolic stroke.

Year introduced: 2021

A type of ischemic stroke resulting from obstruction due to a BLOOD CLOT formed within in a CEREBRAL ARTERY often associated with ATHEROSCLEROSIS. A stroke due to a blood clot in a cerebral vein is a venous infarction (see VENOUS INFARCTION, BRAIN).

Year introduced: 2021

Stroke due to BRAIN ISCHEMIA resulting in interruption or reduction of blood flow to a part of the brain. When obstruction is due to a BLOOD CLOT formed within in a cerebral blood vessel it is a thrombotic stroke. When obstruction is formed elsewhere and moved to block a cerebral blood vessel (see CEREBRAL EMBOLISM) it is referred to as embolic stroke. Wake-up stroke refers to ischemic stroke occurring during sleep while cryptogenic stroke refers to ischemic stroke of unknown origin.

Year introduced: 2021

Restoration of functions to the maximum degree possible in a person or persons suffering from a stroke.

Year introduced: 2017

A mitochondrial disorder characterized by focal or generalized seizures, episodes of transient or persistent neurologic dysfunction resembling strokes, and ragged-red fibers on muscle biopsy. Affected individuals tend to be normal at birth through early childhood, then experience growth failure, episodic vomiting, and recurrent cerebral insults resulting in visual loss and hemiparesis. The cortical lesions tend to occur in the parietal and occipital lobes and are not associated with vascular occlusion. VASCULAR HEADACHE is frequently associated and the disorder tends to be familial. (From Joynt, Clinical Neurology, 1992, Ch56, p117)

Year introduced: 1993

NECROSIS induced by ISCHEMIA in the POSTERIOR CEREBRAL ARTERY distribution system which supplies portions of the BRAIN STEM; the THALAMUS; TEMPORAL LOBE, and OCCIPITAL LOBE. Depending on the size and location of infarction, clinical features include OLFACTION DISORDERS and visual problems (AGNOSIA; ALEXIA; HEMIANOPSIA).

Year introduced: 2000

Infarctions that occur in the BRAIN STEM which is comprised of the MIDBRAIN; PONS; and MEDULLA OBLONGATA. There are several named syndromes characterized by their distinctive clinical manifestations and specific sites of ischemic injury.

Year introduced: 2000

NECROSIS occurring in the MIDDLE CEREBRAL ARTERY distribution system which brings blood to the entire lateral aspects of each CEREBRAL HEMISPHERE. Clinical signs include impaired cognition; APHASIA; AGRAPHIA; weak and numbness in the face and arms, contralaterally or bilaterally depending on the infarction.

Year introduced: 2000

NECROSIS occurring in the ANTERIOR CEREBRAL ARTERY system, including branches such as Heubner's artery. These arteries supply blood to the medial and superior parts of the CEREBRAL HEMISPHERE, Infarction in the anterior cerebral artery usually results in sensory and motor impairment in the lower body.

Year introduced: 2000

Accidental injuries caused by brief high-voltage electrical discharges during thunderstorms. Cardiopulmonary arrest, coma and other neurologic symptoms, myocardial necrosis, and dermal burns are common. Prompt treatment of the acute sequelae, including cardiopulmonary resuscitation, is indicated for survival.

Year introduced: 1991(1989)

NECROSIS of the MYOCARDIUM caused by an obstruction of the blood supply to the heart (CORONARY CIRCULATION).

Year introduced: 1979

Heat stroke caused by exposure to the sun. It is characterized by dangerously high BODY TEMPERATURE; red, hot skin; DELUSIONS; CONVULSIONS; or COMA. It can be a life-threatening emergency and is most common in infants and the elderly.

synthesized by eucaryotic organisms; synthesis of these proteins is sharply curtailed after temperature elevation, when heat shock protein biosynthesis is increased
