American Heart Association gives Seven steps to keep your Brain Healthy from Childhood to Old Age

 

American Heart Association/American Stroke Association Presidential Advisory

American Heart AssociationDallas, TX – A healthy lifestyle benefits your brain as much as the rest of your body — and may lessen the risk of cognitive decline (a loss of the ability to think well) as you age, according to a new advisory from the American Heart Association/American Stroke Association.

Both the heart and brain need adequate blood flow, but in many people, blood vessels slowly become narrowed or blocked over the course of their life, a disease process known as atherosclerosis, the cause of many heart attacks and strokes.

American Heart Association reports Brain Activity may be predictor of Stress-Related Cardiovascular Risk

 

American Heart Association Rapid Access Journal Report

American Heart AssociationDallas, TX – The brain may have a distinctive activity pattern during stressful events that predicts bodily reactions, such as rises in blood pressure that increase risk for cardiovascular disease, according to new proof-of-concept research in the Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.

The new research, the largest brain-imaging study of cardiovascular stress physiology to date, introduced a brain-based explanation of why stress might influence a person’s heart health.

American Heart Association says quitting statins after stroke may raise risk of another stroke

 

American Heart AssociationDallas, TXStroke patients who stopped taking statin drugs three to six months after a first ischemic stroke, the type caused by narrowed arteries, had a higher risk of a having another stroke within a year, according to new research in Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.

Researchers also found that discontinuing statin drugs, which lower cholesterol, between three and six months after a first ischemic stroke was linked to higher risk of death and hospitalization among the patients in the study.

American Stroke Association says Receiving a Clot-Buster Drug before reaching the Hospital may Reduce Stroke Disability

 

American Stroke Association Meeting Report

American Stroke Association - American Heart AssociationHouston, TX – Stroke patients receiving clot-busting medications before arriving at the hospital have a lower risk for disability afterward, according to research presented at the American Stroke Association’s International Stroke Conference 2017.

Researchers analyzed results from 658 stroke patients who were treated with tPA – a drug that dissolves blood clots. About half of the participants received the clot-busting drug at the hospital, and half received it while still in the ambulance.

The study suggests that ambulances with the personnel and equipment capable of diagnosing ischemic stroke may be worth the extra cost, due to the decrease in patient disability afterward. (American Heart Association)

Exercise can significantly improve Brain Function after Stroke according to American Heart Association

 

American Stroke Association Meeting Report

American Heart AssociationHouston, TXStructured exercise training can significantly improve brain function in stroke survivors, according to research presented at the American Stroke Association’s International Stroke Conference 2017.

Stroke is the fifth leading cause of death in the United States, and the leading cause of long-term disability. Studies estimate that up to 85 percent of people who suffer a stroke will have cognitive impairments, including deficits in executive function, attention and working memory.

American Heart Association says High Blood Pressure and Brain Health are Linked

 

American Heart Association Scientific Statement

American Heart AssociationDallas, TXHigh blood pressure, especially in middle age, is associated with an increased risk of cognitive impairment later in life, according to a new statement from the American Heart Association.

The statement, which was published in the American Heart Association journal Hypertension, reviewed multiple studies and provides an overview of what is currently known about how high blood pressure influences brain diseases such as stroke, vascular cognitive impairment and Alzheimer’s disease.

American Heart Association reports Female Smokers face greatest risk for Brain Bleeds

 

American Heart Association Rapid Access Journal Report

American Heart AssociationDallas, 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.

Even light smoking increases the risk, but the greatest risk is among heavy smokers.

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)
