Silent strokes typically cause lesions which are detected via the use of neuroimaging such as MRI. [ 2 ] [ 3 ] The risk of silent stroke increases with age but may also affect younger adults. Women appear to be at increased risk for silent stroke, with hypertension and current cigarette smoking being amongst the predisposing factors.
CT scans may not detect ischemic stroke, especially if it is small, of recent onset, [10] or in the brainstem or cerebellum areas (posterior circulation infarct). MRI is better at detecting a posterior circulation infarct with diffusion-weighted imaging. [79] A CT scan is used more to rule out certain stroke mimics and detect bleeding. [10]

In 2016, a study found that women have a 50 per cent higher chance than men of receiving a misdiagnosis after a heart attack, while researchers found in 2014 that 33 per cent of women are more ...
This type of stroke often causes lesions in the surrounding brain tissue that are visibly detected via neuroimaging techniques such as MRI and computed axial tomography (CT scan). Silent strokes, including silent lacunar infarctions, have been shown to be much more common than previously thought, with an estimated prevalence rate of eleven ...
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.
During the 30-second sprints, go all out, aiming for maximum power output while maintaining a high stroke rate of over 30 strokes per minute (SPM) and using an explosive leg drive.
The first MR images of a human brain were obtained in 1978 by two groups of researchers at EMI Laboratories led by Ian Robert Young and Hugh Clow. [1] In 1986, Charles L. Dumoulin and Howard R. Hart at General Electric developed MR angiography, [2] and Denis Le Bihan obtained the first images and later patented diffusion MRI. [3]
