New imaging study shows how exercise affects the brain

People who exercise have better mental fitness, and a new imaging study from UC Davis Health System shows why. Intense exercise increases levels of two common neurotransmitters -- glutamate and gamma-aminobutyric acid, or GABA -- that are responsible for chemical messaging within the brain.

TTR protein causes autoimmune reaction in joints of juvenile idiopathic arthritis patients

Juvenile idiopathic arthritis, or JIA, is the most common form of childhood arthritis. It appears to be an autoimmune disease, caused by antibodies attacking certain proteins in a person's own tissue. But no "autoantigens" -- the proteins triggering an immune attack -- have been linked to JIA.

New drug shows promise against Huntington's disease

A drug that would be the first to target the cause of Huntington's disease (HD) is effective and safe when tested in mice and monkeys, according to data released today that will be presented at the American Academy of Neurology's 68th Annual Meeting in Vancouver, Canada, April 15 to 21, 2016.

New analytical tool may help diagnose cancer faster than conventional methods

Researchers have developed a new analytical tool for medical applications and biological research that might be used to diagnose cancer more rapidly than conventional methods.

Neurosurgeons use laser probe to deliver chemotherapy drugs to patients with glioblastoma

Using a laser probe, neurosurgeons at Washington University School of Medicine in St. Louis have opened the brain's protective cover, enabling them to deliver chemotherapy drugs to patients with a form of deadly brain cancer.

Scientists develop new optical technique to observe neurotransmitter activity of individual synapses

Columbia University scientists have developed a new optical technique to study how information is transmitted in the brains of mice. Using this method, they found that only a small portion of synapses -- the connections between cells that control brain activity--may be active at any given time.

Study provides pathways to understand complex neurological disorders

Scientists have now described the engineering of a bright red fluorescent protein-based voltage indicator, providing pathways to understanding complex neurological disorders. Designated as FlicR1 (fluorescent indicator for voltage imaging red), these indicators enable imaging of the electrical activity of many genetically targeted neurons with high spatial and temporal resolution.

Study: Most Ebola survivors experience brain symptoms more than six months after initial infection

Most of the 82 Ebola survivors in a new study from the world's largest Ebola outbreak had brain symptoms more than six months after the initial infection. The preliminary results will be presented at the American Academy of Neurology's 68th Annual Meeting in Vancouver, Canada, April 15 to 21, 2016.

Fetal alcohol exposure results in permanent fragmentation in slow-wave sleep

Slow-wave sleep - the deeper sleep during which the brain turns each day's events into permanent memories - is fragmented in adulthood in people exposed to high levels of alcohol in the womb.

Ohio State researchers develop new approach to enhance heart function, cardiovascular performance

For the first time, scientists at The Ohio State University have engineered new calcium receptors for the heart to tune the strength of the heartbeat in an animal model. The research is published online by the journal Nature Communications.

Gamma Knife and RapidArc equally effective at eradicating cancer in the brain

While two advanced radiosurgery approaches — Gamma Knife and RapidArc — offer different strengths, they are equally effective at eradicating cancer in the brain, say researchers at Sidney Kimmel Cancer Center.

Study: Migraine, tension-type headaches may share genetic links with IBS

Migraine and tension-type headaches may share genetic links with irritable bowel syndrome (IBS), according to a preliminary study released today that will be presented at the American Academy of Neurology's 68th Annual Meeting in Vancouver, Canada, April 15 to 21, 2016.

Damage to language network structural hubs can affect severity of aphasia following stroke

When brain regions that control speech and reading comprehension are destroyed due to blockage of blood flow, patients are often unable to speak or comprehend spoken or written language. These difficulties with language, or "aphasia," are a common symptom in the aftermath of stroke. However, in a new study published in Restorative Neurology and Neuroscience, researchers report that damage to the underlying connections among different areas of the brain can also affect the severity of aphasia.

New discoveries provide further evidence for benefits of a good night's sleep

Why does sleeping on it help? This is the question tackled by new research at the University of Bristol, which reveals how brain activity during sleep sorts through the huge number of experiences we encounter every day, filing only the important information in memory.

Researchers identify common molecular alteration in glioblastoma

Glioblastoma is the most aggressive manifestation of brain tumours. Due to its high invasive capacity and uncontrolled, infiltrating growth, it is particularly difficult to manage. Currently, the treatment for this disease consists of a combination of surgery (when possible), radiation and chemotherapy.

SBP study opens door for new approaches to treat muscle diseases

Scientists at Sanford Burnham Prebys Medical Discovery Institute have found a key to enhancing repair of damaged muscle. In work published today in Cell Reports, scientists describe why fetal muscle stem cells (MuSCs) are better at regenerating muscle compared to adult MuSCs.

Neuroscientists identify specific enzyme that plays critical role in spinal muscular atrophy

Neuroscientists have discovered a specific enzyme that plays a critical role in spinal muscular atrophy, and that suppressing this enzyme's activity, could markedly reduce the disease's severity and improve patients' lifestyles.

Findings offer new approach to treating metabolic disorders

A new research study has revealed an important relationship between proteins secreted by the heart and obesity, glucose intolerance, and insulin resistance. The findings, published today in Obesity, offer a new approach to treating metabolic disorders, including type 2 diabetes, by targeting the pathway that controls the proteins' concentration in the blood.

Antibiotics may be linked to delirium and other brain problems

Antibiotics may be linked to a serious disruption in brain function, called delirium, and other brain problems, more than previously thought, according to a "Views and Reviews" article published in the February 17, 2016, online issue of Neurology, a medical journal of the American Academy of Neurology.
