Resuming non-contact physical activity 72 hours after a concussion is safe, and may also reduce symptoms and the risk of delayed recovery, suggests the first and largest real-world, randomized clinical trial on the topic to be conducted with children and youth aged 10 to 18.

Subtle changes in the structure and the diastolic function of a person's heart between early adulthood and middle age may be associated with a decline in thinking and memory skills.

Researchers have demonstrated that a novel combination of two drugs that act as targeted inhibitors, delivered in a nanoparticle formulation, extend the survival of mice with medulloblastoma. The research team believes this laboratory success could be translated into a less toxic treatment for medulloblastoma, the most common malignant pediatric brain tumor.

Using an innovative new imaging technique, researchers have revealed the inner workings of a family of light-sensing molecules in unprecedented detail and speed. The work could inform new strategies in the burgeoning field of optogenetics, which uses light pulses to alter the activity of individual neurons and other cells.

There has to date been no reliable objective method of diagnosing tinnitus. Researchers now show that brainstem audiometry can be used to measure changes in the brain in people with constant tinnitus.

Signs of inflammation in the blood reliably predict and identify severe depression in pregnancy, reports a new study.

New research suggests that chemotherapy could better target brain tumors in mouse models when it was administered at night instead of during the day. That's because the blood-brain barrier was more likely to allow the chemotherapy to pass through it at night. The findings highlight the importance of this area of research in humans, and one day, they could help to improve outcomes in patients with brain tumors.

Researchers exploring dementia-related proteins in the brain identified Apolipoprotein E (ApoE) as a key misfolded protein.

A rose by any other name may smell as sweet, but a chocolate chip cookie labeled 'consumer complaint' won't taste as good as the exact same product described as 'new and improved,' a new study suggests.

While heart disease remains the #1 cause of death worldwide, experts have noted that diseases of the brain -- especially Alzheimer's disease and dementia -- are substantially increasing, and they are often associated with many of the same risk factors that cause heart disease, including high blood pressure, obesity, diabetes and tobacco use.

New research suggests that a virtual reality test in which participants 'go to the shops' could offer a potentially promising way of effectively assessing functional cognition, the thinking and processing skills needed to accomplish complex everyday activities.
