Studies using repetitive transcranial magnetic stimulation (rTMS), a noninvasive technique, to help veterans and active-duty service members living with depression, post-traumatic stress disorder (PTSD), and other lasting consequences of concussion have shown promise. However, there’s an urgent need for studies designed to address the unique patterns of post-concussion symptoms seen in military populations, concludes a review in the November/December issue of the Journal of Head Trauma Rehabilitation (JHTR). The official journal of the Brain Injury Association of America, JHTR is published in the Lippincott portfolio by Wolters Kluwer.
Women who work in the paid labor force in early adulthood and middle age may have slower memory decline later in life than women who do not work for pay, according to a new study published in the November 4, 2020, online issue of Neurology®, the medical journal of the American Academy of Neurology. Researchers found an association between working for pay and slower memory decline regardless of a woman’s marital or parenthood status.

Testing a readily and rapidly available, discreet in-vehicle sensing system could provide the first step toward future widespread, low-cost early warnings of cognitive change in older drivers. The use of an advanced, multimodal approach involves the development of novel driving sensors and integration of data from a battery of cognitive function tests, eye tracking and driving behaviors and factors. These in-vehicle technologies could help detect abnormal driving behavior that may be attributed to cognitive impairment.
A new study suggests that a single episode of extreme drinking in young adults may be linked to almost immediate structural brain atrophy. Adolescence and emerging adulthood are known to represent critical stages for brain development, involving heightened vulnerability to the toxic effects of drinking. Chronic alcohol use among young adults is associated with structural brain abnormalities, especially in the corpus callosum, which transfers information between brain hemispheres — a key function in learning and memory. Preclinical research in rodents suggests that a single drinking episode might result in brain atrophy. However, it was unclear whether and how a single episode of extreme drinking in young adults could affect brain structure. The study, published in Alcoholism: Clinical and Experimental Research, assessed participants before and after a single episode of extreme drinking — consuming more than four to five alcohol-containing beverages in a single episode — scanning the br

A genetic variation in some people may be associated with cognitive decline that can’t be explained by deposits of two key proteins associated with Alzheimer’s disease, amyloid β and tau, according to a study published in the September 16, 2020, online issue of Neurology®, the medical journal of the American Academy of Neurology. The genetic variation leads to alterations in the metabolism of glutathione, an antioxidant, and may be associated with thinning of the cortex of the brain, the study says. The variation is found on the sixth chromosome.
