Children who were born at less than 26 weeks of gestation have a higher risk for later impairments, a new study finds. Although advances in the neonatal intensive care have resulted in increased survival rates for these children, researchers who conducted a follow-up study of 219 extremely preterm children found that almost one-quarter had a [...]
Many students are heavy users of the Internet, social media and cell phones, and showing symptoms similar to drug and alcohol addictions, according to a new study. Researchers asked 200 students to give up all electronic media for a 24-hour time period. Students were then asked to write about their feelings in regards to the [...]
By Betsy Bates Elsevier Global Medical News Breaking News LOS ANGELES (EGMN) – Nearly half of preschool children meet age-adjusted criteria for posttraumatic stress disorder after experiencing a significant traumatic event, and some children are symptomatic even after relatively minor medical procedures, according to a researcher from Tulane University in New Orleans. “Children under 6 [...]
New Neurons Pinpointed as Central to Exercise Benefit In a study in a mouse model that mimics the contribution of social stress to human depression, an environment that promotes exercise and exploration alleviated depressive behavior in the mice. The beneficial effect of activity depended on the growth of new neurons in the adult brain. Background [...]
In-Scanner Tasks Reveal Divergences with Overlapping Disorders A series of imaging studies are revealing that the brain works differently in youth with bipolar disorder (BD) than in chronically irritable children who are often diagnosed with pediatric BD. “This suggests that chronically irritable children may suffer from a syndrome distinct from BD and may require different [...]
WASHINGTON – Self-esteem rises steadily as people age but starts declining around the time of retirement, according to a longitudinal study of men and women ranging in age from 25 to 104. “Self-esteem is related to better health, less criminal behavior, lower levels of depression and, overall, greater success in life,” said the study’s lead [...]
Girls at high risk for depression but without current or past clinically significant symptoms showed abnormal brain function related to anticipating and receiving either a reward or loss, according to a study funded by the National Institute of Mental Health (NIMH).

Like Patients, Engineered Mice Falter at Working Memory Tasks The strongest known recurrent genetic cause of schizophrenia impairs communications between the brain’s decision-making and memory hubs, resulting in working memory deficits, according to a study in mice. “For the first time, we have a powerful animal model that shows us how genetics affects brain circuitry, [...]
