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.
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]
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 ...
However, the mutation causes accumulation of this protein within small to medium-sized blood vessels. [19] This disease often presents in early adulthood with migraines, stroke, mood disturbances, and cognitive deterioration. MRI shows white matter changes in the brain and also signs of repeated strokes. The diagnosis can be confirmed by gene ...
Diagnosis is clinical, and can be established in any patient who develops sustained depressive symptoms after a stroke. [1] While these criteria can appear simple, diagnosis may be challenging due to the overlap between stroke-related neurological symptoms and depression, which can present with or without a typical depressed mood.
A silent stroke (or asymptomatic cerebral infarction) is a stroke that does not have any outward symptoms associated with stroke, and the patient is typically unaware they have suffered a stroke. Despite not causing identifiable symptoms, a silent stroke still causes damage to the brain and places the patient at increased risk for both ...
Silent stroke is a stroke which does not have any outward symptoms, and the patient is typically unaware they have had a stroke. Despite its lack of identifiable symptoms, a silent stroke still causes brain damage and places the patient at increased risk for a major stroke in the future. In a broad study in 1998, more than 11 million people ...
A stroke is an interruption of the blood supply to the brain. Approximately every 40 seconds, someone in the US has a stroke. [7] This can happen when a blood vessel is blocked by a blood clot or when a blood vessel ruptures, causing blood to leak to the brain. If the brain cannot get enough oxygen and blood, brain cells can die, leading to ...
