Researchers at Johns Hopkins Medicine report they have identified a biochemical pathway linking oxidative stress and the amino acid cysteine in Huntington's disease.
Funded by a grant from the National Institutes of Health (NIH)'s National Institute of Mental Health, University of Houston psychology professor Candice Alfano says children who experience inadequate or disrupted sleep are more likely to develop depression and anxiety disorders later in life. The study seeks to determine the precise ways inadequate sleep in childhood produces elevated risk for emotional disorders in later years.
The Center for Behavioral Neuroscience at Georgia State University has received a five-year, $3.2 million grant from the National Institute of Mental Health to investigate the neurochemical mechanisms underlying social stress in males and females.
In research using patient medical records, investigators from Johns Hopkins and Sheppard Pratt Health System report that people with serious mental disorders who were hospitalized for mania were more likely to be on antibiotics to treat active infections than a group of people without a mental disorder.
Abnormalities in brain regions involved in forming insight may help explain why some people with anorexia nervosa have trouble recognizing their dangerous, dysfunctional eating habits.
A study from the Global Burden of Disease collaborative network, published today in The Lancet HIV, found that 74 countries saw increases in age-standardized rates of new infections between 2005 and 2015, according to a new study led by the Institute for Health Metrics and Evaluation.
Women who took part in ASPIRE, a trial that found a vaginal ring containing an antiretroviral drug called dapivirine was safe and helped protect against HIV, will soon be offered the opportunity to use the ring through a new study called HOPE. HOPE will gather additional information on the ring's safety, how women use the ring knowing that it can help reduce their risk of HIV and on the relationship between adherence and HIV protection.
A new study on infantile memory formation in rats points to the importance of critical periods in early-life learning on functional development of the brain. The research, conducted by scientists at New York University's Center for Neural Science, reveals the significance of learning experiences over the first two to four years of human life.
Researchers at the Allen Institute for Brain Science have published an in-depth analysis of a comprehensive molecular atlas of brain development in the non-human primate. This analysis uncovers features of the genetic code underlying brain development in our close evolutionary relative, while revealing distinct features of human brain development by comparison.
Regular cocaine and methamphetamine users can have difficulty choosing between right and wrong, perhaps because the specific parts of their brains used for moral processing and evaluating emotions are damaged by their prolonged drug habits. This is according to a study among prison inmates by Samantha Fede and Dr. Kent Kiehl's laboratory at the University of New Mexico and the nonprofit Mind Research Network. The findings are published in Springer's journal Psychopharmacology.
