A stroke is a medical emergency. Strokes happen when blood flow to your brain stops. Within minutes, brain cells begin to die. There are two kinds of stroke. The more common kind, called ischemic stroke, is caused by a blood clot that blocks or plugs a blood vessel in the brain. The other kind, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. "Mini-strokes" or transient ischemic attacks (TIAs), occur when the blood supply to the brain is briefly interrupted.

How old is your heart?

How old is your heart?

There have been a number of ways to measure the biological health and age of your heart, which has been done conventionally in the past. Blood pressure is one indicator. Other risk indicators include family history of heart disease, level of cholesterol and exercise testing, where you can get heart rate... [More]

Upright posture in patients with Parkinson's disease exacerbates cognitive deficits, study shows

In a new study published online today in the journal Neurology, a research team led by neurologists at Beth Israel Deaconess Medical Center and neuropsychologists at Boston University has shown that when patients with Parkinson's disease experience a drop in blood pressure upon standing up - a condition known as orthostatic hypotension (OH) - they exhibit significant cognitive deficits.

Symptom trends may help predict recovery of patients suffering from post-concussion syndrome

Symptom trends may help predict recovery of patients suffering from post-concussion syndrome

Researchers at the Krembil Neuroscience Centre's Canadian Concussion Centre have identified symptom trends that may not only help predict how soon patients suffering from post-concussion syndrome (PCS) will recover, but also provide insight on how to treat those who experience persistent concussion symptoms.

New study finds smoking cessation at any age reduces risk of death

New study finds smoking cessation at any age reduces risk of death

Tobacco use continues to be a major cause of cancer and premature death. Most studies of cigarette smoking and mortality have focused on middle-aged populations, with fewer studies examining the impact of tobacco cessation on disease and mortality risk among the elderly. [More]

New self-regulating smart patch releases blood-thinning drugs when necessary

An interdisciplinary team of researchers has developed a smart patch designed to monitor a patient's blood and release blood-thinning drugs as needed to prevent the occurrence of dangerous blood clots - a condition known as thrombosis. [More]
Iraq and Afghanistan war veterans with epilepsy have higher mortality risk, study reveals

Iraq and Afghanistan war veterans with epilepsy have higher mortality risk, study reveals

U.S. Iraq and Afghanistan war veterans (IAVs) with epilepsy were more than twice as likely to die between 2011 and 2015 as were similar veterans without epilepsy. A study published Nov. 11 in the U.S. Centers for Disease Control and Prevention's Morbidity and Mortality Weekly Report revealed that IAVs were found to have a higher prevalence of mental and physical comorbidity and to have substantially higher mortality than were veterans without epilepsy.

Improving innovation uptake in the NHS

Improving innovation uptake in the NHS

I think innovation is one of those rather slippery terms that means different things to different people. First of all, I would make a distinction between innovations that are essentially about a new, physical product and innovations that are more to do with services or processes. [More]

Study finds upward trend in stroke rates among younger generations

Older baby boomers—those born between 1945 and 1954—can proudly boast a new label: the "stroke-healthiest generation," according to a Rutgers study that found the lowest incidence of ischemic stroke in this age group within the past 20 years. [More]
