Stroke News and Research

RSS

A stroke is a medical emergency. Strokes happen when blood flow to your brain stops. Within minutes, brain cells begin to die. There are two kinds of stroke. The more common kind, called ischemic stroke, is caused by a blood clot that blocks or plugs a blood vessel in the brain. The other kind, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. "Mini-strokes" or transient ischemic attacks (TIAs), occur when the blood supply to the brain is briefly interrupted.

Extreme trait values often have simpler genetic explanations than thought

Researchers at the Icahn School of Medicine at Mount Sinai have found evidence that people who fall at the extreme high or low ends of certain traits, such as cholesterol, blood glucose, height, and age at menopause, are more likely to have a simple genetic explanation than previously thought.

Why blood pressure rises faster in women after midlife

This review examines how sex-specific blood pressure trajectories are shaped by genetics, hormones, metabolic risk factors, lifestyle exposures, environmental stressors, and medical treatments. It highlights that women generally have lower blood pressure earlier in life but may experience steeper increases with aging, especially around and after menopause, with exogenous stressors appearing to have a greater impact in women than in men.

Hydroxychloroquine lowers heart risks in skin lupus patients

A study led by investigators from Johns Hopkins Medicine found that some patients with discoid lupus erythematosus - a form of skin lupus commonly diagnosed in young to middle-aged Black women that causes disc-shaped plaques to form on the body - were less likely to experience complications, such as diabetes, hypertension and coronary artery disease if they were prescribed hydroxychloroquine.

Disrupted sleep rhythms may increase dementia risk through impaired waste clearance

Why are conditions such as chronic stress, depression, cardiovascular disease, fragmented sleep, and aging all associated with a higher risk of dementia? In a new review piece in Science, University of Rochester Medicine neuroscientist Maiken Nedergaard, MD, DMSc, proposes that many of these seemingly different conditions may converge on the same biological problem: disruption of a sleep-dependent brain rhythm that helps clear waste from the brain.
