Dallas, TX – Bleeding inside the lining of the brain (subarachnoid hemorrhage) is significantly more common among smokers, especially female smokers, than among people who do not smoke, according to new research in the American Heart Association’s journal Stroke.
Subarachnoid hemorrhage results from bleeding into the lining between the brain’s surface and underlying brain tissue.
American Stroke Association reports Rapid symptom improvement may not indicate better stroke recovery
American Stroke Association Meeting Report
Los Angeles, CA – Stroke patients whose symptoms quickly improved before hospital arrival did not always have better recoveries than other patients, according to research presented at the American Stroke Association’s International Stroke Conference 2016.
“Patients with very early rapid neurological improvement when first examined at the hospital still need to be considered for therapy to dissolve blood clots, given the high rate of unfavorable outcome,” said Clotilde Balucani, M.D., Ph.D., lead author and research assistant professor in neurology at The State University of New York Downstate Medical Center in Brooklyn.
American Stroke Association reports Imaging, not Time, may determine who is right for Stroke Clot Removal
American Stroke Association Meeting Report
Los Angeles, CA – Brain imaging may accurately identify patients likely to benefit from stroke clot removal instead of relying on the time since symptoms began as an indicator of treatment eligibility, according to research presented at the American Stroke Association’s International Stroke Conference 2016.
An ischemic stroke is caused by lack of blood reaching part of the brain. Endovascular treatment – which mechanically removes the blood clot blocking the path to the brain – benefits patients when performed within six hours of symptom onset. Drug treatment to bust the clot is beneficial up to 4.5 hours.
American Heart Association Rapid Access Journal Report
Dallas, TX – Poor sleep quality in elderly persons is associated with more severe arteriosclerosis in the brain as well as a greater burden of oxygen-starved tissue (infarcts) in the brain – both of which can contribute to the risk of stroke and cognitive impairment. The findings are reported in the American Heart Association’s journal Stroke.
The relationship between cardiovascular disease and so-called “fragmented” sleep has been studied in the past, but this is the first study to look specifically for an association between sleep fragmentation and detailed microscopic measures of blood vessel damage and infarcts in autopsied brain tissue from the same individuals.

Pasadena, CA – To operate on the brain, doctors need to see fine details on a small scale. A tiny camera that could produce 3-D images from inside the brain would help surgeons see more intricacies of the tissue they are handling and lead to faster, safer procedures.
An endoscope with such a camera is being developed at NASA’s Jet Propulsion Laboratory in Pasadena, California. MARVEL, which stands for Multi Angle Rear Viewing Endoscopic tooL, has been honored this week with the Outstanding Technology Development award from the Federal Laboratory Consortium. An endoscope is a device that examines the interior of a body part.
Dallas, TX – A CT scan of the brain within 24 hours of a mild, non-disabling stroke can predict when patients will be at the highest risk of another stroke or when symptoms may worsen, according to new research published in the American Heart Association journal Stroke.
Like stroke, a transient ischemic attack (TIA) is caused by restricted blood supply to the brain. Symptoms may last only a few minutes.
Dallas, TX – Treatments involving neck manipulation may be associated with stroke, though it cannot be said with certainty that neck manipulation causes strokes, according to a new scientific statement published in the American Heart Association’s journal Stroke.
Cervical artery dissection (CD) is a small tear in the layers of artery walls in the neck. It can result in ischemic stroke if a blood clot forms after a trivial or major trauma in the neck and later causes blockage of a blood vessel in the brain.
Dallas, TX – Cognitive abilities such as memory and attention are not only important after a stroke but also before; according to research published in the American Heart Association journal Stroke.
Previous studies have shown poor cardiovascular health can increase the risk of cognitive impairment such as problems in memory and learning. However, the opposite idea that cognitive impairment may impact cardiovascular health, specifically stroke, was not established before.
May is American Stroke Month
In a new study, people with a history of migraine headaches had double the odds of ischemic silent brain infarction compared to people who said they didn’t have migraines.
American Heart Association says Marijuana use may increase Heart Complications in young, middle-aged Adults
Dallas, TX – Marijuana use may result in cardiovascular-related complications — even death — among young and middle-aged adults, according to a French study reported in the Journal of the American Heart Association.
“In prior research, we identified several remarkable cases of cardiovascular complications as the reasons for hospital admission of young marijuana users,” said Émilie Jouanjus, Pharm.D., Ph.D., lead author of the study and a medical faculty member at the Centre Hospitalier Universitaire de Toulouse in Toulouse, France.
