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.

People with higher levels of IgG/IgM antibodies less likely to have heart attack

People with higher levels of IgG/IgM antibodies less likely to have heart attack

Measuring antibody levels in the blood could be used to detect a person's heart attack risk after researchers, part-funded by the British Heart Foundation, discovered that higher levels of these antibodies are linked to a lower heart attack risk. [More]
Brain imaging finds link between blood-brain barrier disruption and severity of bleeding after stroke therapy

Brain imaging finds link between blood-brain barrier disruption and severity of bleeding after stroke therapy

In a study of stroke patients, investigators confirmed through MRI brain scans that there was an association between the extent of disruption to the brain's protective blood-brain barrier and the severity of bleeding following invasive stroke therapy. The results of the National Institutes of Health-funded study were published in Neurology. [More]

Cerebral vessel disease increases Alzheimer's dementia risk

Cerebral vessel disease may be an under-recognised risk factor for Alzheimer's disease dementia, say researchers. [More]
Salk Institute researchers use super-resolution microscope to image vital receptors in lymph nodes

Salk Institute researchers use super-resolution microscope to image vital receptors in lymph nodes

When the body is fighting an invading pathogen, white blood cells--including T cells--must respond. Now, Salk Institute researchers have imaged how vital receptors on the surface of T cells bundle together when activated. [More]
Complex 36-point therapeutic personalized program can help reverse memory loss in early AD patients

Complex 36-point therapeutic personalized program can help reverse memory loss in early AD patients

Results from quantitative MRI and neuropsychological testing show unprecedented improvements in ten patients with early Alzheimer's disease (AD) or its precursors following treatment with a programmatic and personalized therapy. Results from an approach dubbed metabolic enhancement for neurodegeneration are now available online in the journal Aging. [More]

Study links whole grain consumption to positive health effects

Eating three more portions of dietary fiber a day--say, two pieces of whole grain bread and a bowl of whole grain breakfast cereal--is associated with a lower risk for all cardiovascular diseases and for dying of cancer, diabetes, and respiratory and infectious diseases, a study just published in the BMJ has shown.

Researchers explore why women have ubiquitous survival advantage than men

Researchers explore why women have ubiquitous survival advantage than men

Women live longer than men. This simple statement holds a tantalizing riddle that Steven Austad, Ph.D., and Kathleen Fischer, Ph.D., of the University of Alabama at Birmingham explore in a perspective piece published in Cell Metabolism on June 14. [More]
MicroRNA plays role in blocking development of arterial thrombosis

MicroRNA plays role in blocking development of arterial thrombosis

The dangers of arterial thrombosis - the formation of blood clots that can block arteries and cause illness or death - can escalate through a vicious cycle of coagulation and inflammation. [More]
Female migraine patients have increased cardiovascular disease risk

Female migraine patients have increased cardiovascular disease risk

Women who suffer from migraine headaches have a slightly increased risk of developing cardiovascular disease in later life. A team of researchers led by Prof. Tobias Kurth, Head of the Institute of Public Health at Charité - Universitätsmedizin Berlin, has now been able to establish the following: female migraine patients have a higher risk of stroke or heart attacks than women without migraine.
