Regular aerobic exercise beginning in middle age may lessen severity of stroke in old age

Fri, 24 Feb 2017 11:17:31 EST

Regular aerobic exercise may protect the collateral circulation and lessen the severity of strokes later in life.

Sugar's 'tipping point' link to Alzheimer's disease revealed

Thu, 23 Feb 2017 12:42:53 EST

For the first time a molecular 'tipping point' has been demonstrated in Alzheimer's, linking high blood sugar with this debilitating disease.

Itch neurons play a role in managing pain

Wed, 22 Feb 2017 12:56:40 EST

There are neurons in your skin that are wired to sense itchy things. These neurons are separate from the ones that detect pain, and yet, chemical-induced itch is often accompanied by mild pain such as burning and stinging sensations. But when it comes to sending signals toward your brain through your spinal cord, itch and mild pain can go through the same set of spinal cord neurons.

Making it harder to 'outsmart' concussion tests

Wed, 22 Feb 2017 12:56:26 EST

Concussion testing on the athletic field depends upon comparing an athlete's post-concussion neurocognitive performance with the results of a previously administered baseline test. Experts believe some athletes, in hopes of a quicker post-injury return to play, may 'sandbag' the concussion test by giving a lackadaisical baseline performance. A researcher has developed a statistical technique to detect when an athlete is sandbagging.

Model helps explain why some patients with multiple sclerosis have seizures

Tue, 21 Feb 2017 14:20:40 EST

MS patients are three to six times more likely to develop seizures. Using a mouse model, a team of scientists has found for the first time that chronic demyelination is closely linked to, and is likely the cause of, these seizures. A new study could lead to the development of drugs aimed at reducing seizures in multiple sclerosis, potentially benefiting epilepsy patients as well.

A novel principle to mobilize neurons for brain repair

Tue, 21 Feb 2017 08:17:32 EST

Restorative neuroscience is a rapidly advancing scientific field considering our progressively aging society. Redirecting immature neurons that reside in specific brain areas towards the sites of brain damage is an appealing strategy for the therapy of acute brain injury or stroke. A collaborative effort has revealed that some mature neurons are able to reconfigure their local microenvironment such that it becomes conducive for adult-born immature neurons to extensively migrate. Thus, a molecular principle emerges that can allow researchers to best mobilize resident cellular reserves in the adult brain and guide immature neurons to the sites of brain damage.

Repetitive head injuries may not cause movement problems for former NFL players

Sun, 19 Feb 2017 16:51:00 EST

Former NFL players who had repeated head injuries may not have significant problems with motor functions later in life, according to a preliminary study.

Scientists uncover how Zika virus causes microcephaly

Fri, 17 Feb 2017 16:10:23 EST

A multidisciplinary team has uncovered the mechanisms that the Zika virus uses to alter brain development, outlines a new report.

Big improvement to brain-computer interface

Fri, 17 Feb 2017 09:59:43 EST

Researchers have developed an improved type of electrode that is more durable, lasts longer in the body and transmits a clearer, more robust signal than electrodes made from current state-of-the-art materials. This could allow for improved restoration of mobility after spinal cord accidents, as well as improved powered prosthetic limbs.

Targeted radiosurgery better than whole-brain radiation for treating brain tumors

Thu, 16 Feb 2017 13:03:35 EST

Tumors that originate in other organs of the body and spread to the brain are known as metastatic brain tumors. According to the American Brain Tumor Association, this tumor type is the most common in adults, affecting as many as 300,000 people each year. Researchers compared two common postsurgical therapies for metastatic brain tumors and found that stereotactic radiosurgery can provide better outcomes for patients compared to whole-brain radiation.
