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]
Ischemic stroke is caused by interruption of the blood supply to the brain, while hemorrhagic stroke results from the rupture of a blood vessel or an abnormal vascular structure. About 87% of stroke is ischemic, with the rest being hemorrhagic. Bleeding can develop inside areas of ischemia, a condition known as "hemorrhagic transformation." It ...
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. [3] Ischemia leads to alterations in brain metabolism, reduction in metabolic rates, and energy crisis. [4]
Acute ischemic stroke is a neurological emergency typically caused by a blood clot blocking blood flow in a vessel in the brain. [15] Chronic ischemia of the brain may result in a form of dementia called vascular dementia . [ 16 ]
Stroke. A stroke is when part of your brain loses its blood supply. Strokes are a type of cerebrovascular disease affecting the blood vessels in your brain. The main types of stroke are: Ischemic ...
The most common presentation of cerebrovascular disease is an ischemic stroke or mini-stroke and sometimes a hemorrhagic stroke. [2] Hypertension (high blood pressure) is the most important contributing risk factor for stroke and cerebrovascular diseases as it can change the structure of blood vessels and result in atherosclerosis . [ 5 ]
ESUS is a diagnosis of exclusion based on radiological and cardiological examinations. For exclusion of haemorrhagic or lacunar strokes CT or MRI imaging is needed. Both procedures also allow detection of embolic pattern of ischemic lesions. 12-lead ECG and cardiac monitoring for at least 24 h with automated rhythm detection are mandated to exclude atrial fibrillation; echocardiography (TTE ...
Total anterior circulation stroke syndrome (TACS) refers to the symptoms of a patient who clinically appears to have had a total anterior circulation infarct, but who has not yet had any diagnostic imaging (e.g. CT Scan) to confirm the diagnosis. It is diagnosed when it causes all 3 of the following symptoms: Higher dysfunction Dysphasia
