New ‘brain health index’ can predict how well patients will do after stroke

A new computer programme developed by scientists at the Universities of Edinburgh and Glasgow can assess whole brain deterioration and help predict cognitive function after stroke up to ten times more accurately than current methods. The new approach, published today in the International Journal of Stroke, can quantify visible brain injury from cerebral small vessel […]

Decision-making predicts future drug addiction in recreational users

Activity in decision-making brain regions of people who use recreational stimulants predicts who will discontinue use and who will develop a drug use disorder, according to a new study led by Martin Paulus, Ph.D., of Laureate Institute of Brain Research, Tulsa, Oklahoma. The study, which appears in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging, measured brain […]

Tai Chi improves brain metabolism and muscle energetics in older adults, study finds

A new Journal of Neuroimaging study provides insights into the biochemical mechanisms by which Tai Chi — a mind-body exercise — may provide both physical and psychological benefits. Using magnetic resonance spectroscopy, a non-invasive method of measuring brain and muscle chemistry using MRI machines, tests conducted in 6 older adults enrolled in a 12-week Tai […]
