A new study indicates that playing video games for a limited amount of time each week may provide benefits to children, but too much can be detrimental. The findings are published in the Annals of Neurology.

There's much debate over the potential benefits and risks of video gaming in children and teens. To provide some clarity, Jesus Pujol, MD, of the Hospital del Mar in Spain, and his colleagues investigated the relationship between weekly video game use and certain cognitive abilities and conduct-related problems.

Scientists from the Swiss Tropical and Public Health Institute (Swiss TPH) and the Peruvian Instituto de Investigación Nutricional (IIN) adapted the urban-based Peruvian National Early Child Development Programme (Wawa Wasi) and brought it to the doorstep of people living in the rural Cajamarca region.

KOBE, JAPAN, September 9, 2016 - The world's population of older adults is expected to double to 2 billion by 2050. With these unprecedented demographic changes, the potential for fraud associated with cognitive decline is becoming a pressing issue in the financial services industry.

A misunderstanding of how the certain parts of the brain function has hampered the creation of pharmaceuticals to effectively address fear and anxiety disorders, a pair of researchers has concluded. Their analysis, which appears in the latest issue of the American Journal of Psychiatry, also offers new insights into neurological processes, with the aim of overcoming existing barriers to drug development.

PROVIDENCE, R.I. [Brown University] -- Volunteers who started an experiment feeling neutral about certain faces they saw ended up unknowingly adopting the feelings that scientists induced via an MRI feedback technique, according to newly published research.

DURHAM, N.C. -- In 1959, a scientist named Edward Gray showed that the miniscule gaps between neurons where chemical messages are sent, called synapses, come in two main varieties, which researchers later dubbed "excitatory" and "inhibitory."

PHILADELPHIA - A study of a new mouse model identifies a drug target that has the potential to increase social interaction in individuals with some forms of autism spectrum disorder (ASD), according to researchers in the Perelman School of Medicine at the University of Pennsylvania. The team published their work in Biological Psychiatry.

Stanford University School of Medicine researchers have located an intracellular defect that they believe is probably common to all forms of Parkinson's disease.

This defect, which precedes the death of a group of nerve cells whose loss is the hallmark of the condition, play a critical role in triggering that die-off.

An intriguing finding in nematode worms suggests that having a little bit of extra fat may help reduce the risk of developing some neurodegenerative diseases, such as Huntington's, Parkinson's and Alzheimer's diseases.

What these illnesses have in common is that they're caused by abnormal proteins that accummulate in or between brain cells to form plaques, producing damage that causes mental decline and early death.

CAMBRIDGE, MA -- When asked to visualize your childhood home, you can probably picture not only the house you lived in, but also the buildings next door and across the street. MIT neuroscientists have now identified two brain regions that are involved in creating these panoramic memories.

These brain regions help us to merge fleeting views of our surroundings into a seamless, 360-degree panorama, the researchers say.
