In honor of Brain Awareness Week, our focus is on research that looks at brain injury, neurodegenerative disease, and mental health.
The Department of Defense estimates that 22 percent of all combat casualties from Iraq and Afghanistan are brain injuries. TBI is also a significant cause of disability outside of military settings, most often as the result of assaults, falls, automobile accidents, or sports injuries. It can involve symptoms ranging from headaches, irritability, and sleep disorders to memory problems, slower thinking, and depression.
* For more information on research devoted to brain health see our topic pages on Alzheimer's Disease, Depression, Mental Health, Parkinson's Disease, and Posttraumatic Stress Disorder (PTSD).

Lab study suggests curcumin could improve memory, mood in Gulf War illness
Curcumin may lead to better cognitive and mood for those with Gulf War illness, according to a rat study by Olin E. Teague Veterans' Medical Center and Texas A&M researchers. Curcumin is a natural antioxidant compound found in turmeric and other plants, and is sometimes sold as an herbal supplement. Rats with simulated Gulf War illness symptoms were treated with either curcumin or a placebo for 30 days. Those in the curcumin group had better cognitive and mood function, based on behavioral tests. They also had better neurogenesis (growth and development of nerve tissue) and lower inflammation than the placebo group. The researchers hypothesize that changes in gene expression caused by curcumin could improve memory and mood symptoms related to Gulf War illness. (Brain, Behavior, and Immunity, Feb. 15, 2018)
Memory tests are accurate for diagnosing Alzheimer's
Memory tests are able to differentiate between those with and without Alzheimer's disease, found a review by researchers from several VA systems. In the 47 studies included by the researchers, measures of immediate and delayed memory had high diagnostic accuracy for Alzheimer's. Memory tests had lower accuracy for diagnosing mild cognitive impairment, based on 38 studies. While memory tests and other psychological testing can be useful for diagnosing Alzheimer's and other cognitive deficits, they are not required in the current diagnosis criteria. The researchers suggest that these tests should be emphasized when diagnosing the conditions. (Neuropsychology Review, December 2017)
