Patients at a high risk for a second stroke who received intensive medical treatment had fewer strokes and deaths than patients who received a brain stent in addition to the medical treatment, a large nationwide clinical trial has shown. The investigators published the results in the online first edition of the New England Journal of Medicine [1]. The National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health, funded the trial. The medical regimen included daily blood-thinning medications and aggressive control of blood pressure and cholesterol.

New enrollment in the study was stopped in April because early data showed significantly more strokes and deaths occurred among the stented patients at the 30-day mark compared to the group who received the medical management alone.

The National Institutes of Health (NIH) has partnered with the Department of Defense (DoD) to build a central database on traumatic brain injuries. Funded at $10 million over four years, the Federal Interagency Traumatic Brain Injury Research (FITBIR) database is designed to accelerate comparative effectiveness research on brain injury treatment and diagnosis. It will serve as a central repository for new data, link to current databases and allow valid comparison of results across studies.

By isolating cells from patients’ spinal tissue within a few days after death, researchers funded by the National Institutes of Health have developed a new model of the paralyzing disease amyotrophic lateral sclerosis (ALS). They found that during the disease, cells called astrocytes become toxic to nerve cells — a result previously found in animal models but not in humans. The new model could be used to investigate many more questions about ALS, also known as Lou Gehrig’s disease.

Key cells in the brain region known as the hippocampus are formed in the base of the brain late in fetal life and undertake a long journey before reaching their final destination in the center of the brain shortly after birth, according to researchers at the National Institutes of Health (NIH).

The largest and most rigorous twin study of its kind to date has found that shared environment influences susceptibility to autism more than previously thought.

The study, supported by the National Institutes of Health, found that shared environmental factors — experiences and exposures common to both twin individuals — accounted for 55% of strict autism and 58% of more broadly defined autism spectrum disorders (ASD). Genetic heritability accounted for 37% of autism and 38% of ASD. Random environmental factors not shared among twins play a much smaller role.
