WHAT: Many people with HIV on antiretroviral therapy (ART) have viral genetic material in the cells of their cerebrospinal fluid (CSF), and these individuals are more likely to experience memory and concentration problems, according to new data published online today in the Journal of Clinical Investigation. A study of 69 individuals on long-term ART found…
Amyotrophic lateral sclerosis, or ALS, is an adult-onset neurodegenerative disease that causes paralysis and ultimately death when the nerves enervating the lungs cease to carry the signals needed for breathing.

Chemotherapy treatment for people who have advanced bowel cancer and a particular genetic mutation is commonly ineffective. A combination of three different drugs could be the key to improved treatment. New research reveals the power of triple therapy when it comes to tackling aggressive bowel cancer. The outlook for people with standard bowel cancer —…
In this Spotlight feature, we investigate whether the bacteria that live in our guts could influence our blood pressure. If so, could they guide future treatment? Hypertension is growing in prevalence, but can we blame gut bacteria? Scientists are growing increasingly interested in the role of gut bacteria. Each week, journals publish many study papers…

What The Study Did: This study of 1,600 older adults free of dementia at baseline examined whether accumulation over a lifetime of cognitive and social activities was associated with a slower rate of memory loss and a reduced risk of dementia, taking into account brain pathologies. Authors: Xiuying Qi, Ph.D., and Weili Xu, M.D., Ph.D.,…
Bottom Line: This observational study looked at whether a healthy lifestyle was associated with a lower risk of dementia regardless of genetic risk. Genetic factors are associated with increased risk of dementia but to what extent these might be offset by lifestyle factors is unknown. Genetic information from the UK Biobank was available for the…
