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.
Nashville, TN – Traumatic brain injury can occur as a result of any head injury. Whether it is a fall from a bicycle or a motorcycle crash, a sports concussion or a head trauma to one of our brave veterans from an explosion on the battlefield, the delicate brain can suffer significant after affects.
Many of these injuries can be prevented. During observances of Brain Injury Awareness Month, the Department of Health is reminding Tennesseans of the importance of wearing helmets while riding motorcycles and bicycles to help prevent brain injuries. «Read the rest of this article»
American Heart Association says consistent blood pressure control may cut rate of second stroke in half
Dallas, TX – Stroke survivors who consistently control their blood pressure may reduce the likelihood of a second stroke by more than half, according to new research in the American Heart Association journal Stroke.
For the study, researchers analyzed the results from the Vitamin Intervention for Stroke Prevention (VISP) trial, which enrolled 3,680 ischemic stroke patients ages 35 and older in 1996-2003.
American Heart Association reports Early Strokes leave many young adults with long-lasting disability
American Heart Association Rapid Access Journal Report
Dallas, TX – One-third of people who survive a stroke before age 50 are unable to live independently or need assistance with daily activities 10 years after their stroke, according to research in the American Heart Association journal Stroke.
About 10 percent of strokes occur in 18- and 50-year-olds.
“Even if patients seem relatively well recovered with respect to motor function, there may still be immense ‘invisible’ damage that leads to loss of independence,” said Frank-Erik de Leeuw, Ph.D., senior author of the study and associate professor of neurology at the Radboud University Nijmegen Medical Center in the Netherlands. «Read the rest of this article»
