American Stroke Association reports Rapid symptom improvement may not indicate better stroke recovery

 

American Stroke Association Meeting Report

American Stroke Association - American Heart AssociationLos 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

American Stroke Association - American Heart AssociationLos 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 report shows Poor Sleep in Seniors linked to Hardened Brain Arteries

 

American Heart Association Rapid Access Journal Report

American Heart AssociationDallas, 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.

Elderly people who sleep poorly and awaken frequently are more likely to have hardened blood vessels or oxygen-starved tissue in the brain. (American Heart Association)

NASA is developing 3-D Camera that can take images inside the Brain

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, 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.

American Heart Association says Images of Brain after Mild Stroke predict future risk

 

American Heart AssociationDallas, 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.

American Heart Association states Neck manipulation may be associated with Stroke

 

American Heart AssociationDallas, 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.

American Heart Association says Slowing Brain Functions linked to increased risk of Stroke, Death

 

American Heart AssociationDallas, 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.

American Heart Association says Older Migraine Sufferers may have more Silent Brain Injury

 

May is American Stroke Month

American Heart AssociationDallas, TX – Older migraine sufferers may be more likely to have silent brain injury, according to research published in the American Heart Association’s journal Stroke.

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

 

American Heart AssociationDallas, 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.

Tennessee Department of Health says Wearing Helmets Saves Lives and Money

 

Tennessee Department of Health - TDOHNashville, 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»
