African-American men who have sex with men (MSM) remain at heightened risk for HIV infection and account for the largest number of African-Americans living with HIV/AIDS. It has long been understood that there is a clear and persistent association between poverty, transactional sex behavior, and HIV risk. A new University of Pennsylvania School of Nursing (Penn Nursing) study has investigated how educational status relates to HIV risk in this population.
A team of researchers at University of California San Diego School of Medicine and Veterans Affairs San Diego Healthcare System have analyzed all eight published longitudinal studies of mortality in schizophrenia that met their strict research criteria and found that the mean standardized mortality ratio -- a measure of the mortality rate in schizophrenia -- has increased 37 percent from pre-1970s studies to post-1970s studies.
New data confirm that suicide attempts among US adults are on the rise, with a disproportional effect on younger, socioeconomically disadvantaged adults with a history of mental disorders.
Marijuana may bring on temporary paranoia and other psychosis-related effects in individuals at high risk of developing a psychotic disorder, finds a preliminary study from researchers at Columbia University Medical Center (CUMC).
Scientists at the Scripps Research Institute have found a new approach to the 'reprogramming' of ordinary adult cells into stem cells.
A study from Aarhus BSS of almost one million Danish children shows that the use of antidepressants during pregnancy increases the risk of your child being diagnosed with a psychiatric disorder later in life. However, heritability also plays a part, according to the researchers.
A combination of whole exome sequencing, machine learning, and network analysis, has identified new, ultra-rare gene mutations within specific biological pathways that may contribute to eating disorders, according to a study by researchers at the University of Iowa Carver College of Medicine and the Eating Recovery Center in Dallas, Texas.
Disruptions to the brain's internal GPS result in some of the severe memory deficits seen in schizophrenia. The new study in mouse models of the disorder marks the first time that schizophrenia's effects have been observed with such precision and clarity. The findings offer a promising entry point for attacking a near-universal and debilitating symptom of schizophrenia, memory deficits, which has thus far withstood all forms of treatment.
Mount Sinai research finds that when making decisions, monkeys use different brain areas to weigh value and availability.
Researchers found that inattentiveness in childhood was linked to worse academic performance up to 10 years later in children with and without ADHD, even when they accounted for the children's intellectual ability. The results highlight the long-term effects that childhood inattention can have on academic performance, and suggest that parents and teachers should address inattentiveness in childhood.
