Better measure of 'good cholesterol' can gauge heart attack and stroke risk in some populations
(UT Southwestern Medical Center) For decades, high-density lipoprotein (HDL) cholesterol has been dubbed 'good cholesterol' because of its role in moving fats and other cholesterol molecules out of artery walls. People with higher HDL cholesterol levels tend to have lower rates of cardiovascular disease, studies have shown.

Without intervention, a 70% reduction in strokes or death in patients with brain AVMs
(University of Montreal Hospital Research Centre (CRCHUM)) For people with a brain arteriovenous malformation (AVM), a congenital vascular system defect, fate has a name: stroke. To avoid this risk, patients sometimes undergo interventions to remove the malformation. But is this very beneficial? Not necessarily. According to an international clinical trial, co-directed by researchers from the University of Montreal Hospital Research Centre (CRCHUM), interventional treatment--by neurosurgery, neuroradiology or radiation therapy--could be more dangerous than the disease itself.

Gut bacteria may modify behavior in worms, influencing eating habits
(NIH/National Institute of Neurological Disorders and Stroke) Gut bacteria are tiny but may play an outsized role not only in the host animal's digestive health, but in their overall well-being. According to a new study in Nature, specific gut bacteria in the worm may modify the animal's behavior, directing its dining decisions. The research was funded in part by the National Institutes of Health.

RIT earns NIH grant to use virtual reality to help stroke patients regain lost vision
(Rochester Institute of Technology) Scientists from Rochester Institute of Technology and the University of Rochester aim to use virtual reality to help restore vision for people with stroke-induced blindness. The team of researchers led by Gabriel Diaz, associate professor at RIT's Chester F. Carlson Center for Imaging Science, received a grant from the National Institutes of Health to develop a method they believe could revolutionize rehabilitation for patients with cortically induced blindness.

NIH study links cigarette smoking to higher stroke risk in African Americans
(NIH/National Heart, Lung and Blood Institute) African Americans who smoke are nearly 2.5 times more likely to have a stroke than those who never smoked, while former smokers show a similarly lower risk as never smokers, according to a new study funded by the National Institutes of Health.

Risk of stroke may more than double for African Americans who smoke
(American Heart Association) Current cigarette smoking and the number of cigarettes smoked per day are associated with more than double the risk of stroke among African Americans.Researchers suggest more public information campaigns should be geared toward warning African Americans about the increased risk of stroke from cigarette smoking.

Rate over time of stroke caused by brain bleeding
(JAMA Network) This observational study looked at the rate and risk factors of stroke caused by bleeding within the brain (intracerebral hemorrhage) between 1948 and 2016 among 10,000 participants in the Framingham Heart Study. There have been conflicting results in other studies on whether the rate of this often deadly type of stroke is changing.

Study ties stroke-related brain blood vessel abnormality to gut bacteria
(NIH/National Institute of Neurological Disorders and Stroke) In a nationwide study, NIH funded researchers found that the presence of abnormal bundles of brittle blood vessels in the brain or spinal cord, called cavernous angiomas (CA), are linked to the composition of a person's gut bacteria. Also known as cerebral cavernous malformations, these lesions which contain slow moving or stagnant blood, can often cause hemorrhagic strokes, seizures, or headaches.

Reducing inflammation boosts cognitive recovery after stroke, may extend treatment window
(Medical University of South Carolina) Reperfusion therapy, the gold standard in stroke treatment, returns blood flow to the affected brain area and must be administered within four hours of stroke to minimize hemorrhage risk. Even with successful return of blood flow, full brain function recovery is rare. Medical University of South Carolina researchers have shown in a preclinical stroke model that adding a unique compound to reduce brain inflammation significantly improves cognitive recovery and extends the treatment window.

Sleep-wake disturbances can predict recurrent events in stroke survivors
(Spink Health) The study, conducted in Switzerland, found that having multiple sleep-wake disturbances such as sleep-disordered breathing, extreme long or short sleep duration, insomnia and restless leg syndrome independently and significantly increased the risk of a new cardio-cerebrovascular event in the two years following a stroke.

'Time is vision' after a stroke
(University of Rochester) University of Rochester researchers studied stroke patients who experienced vision loss and found that the patients retained some visual abilities immediately after the stroke but these abilities diminished gradually and eventually disappeared permanently after approximately six months. Early intervention in the form of visual training appears to stop this gradual loss of visual processing that stroke victims may experience. It is therefore important for occipital stroke patients to receive visual training early on after a stroke.
