Adolescents who are both cyberbullies and victims experience all these conditions, highlighting the need for clear norms and supervision to prevent cyberbullying.
Researchers exposed fetal monkeys to x-rays and found a profound deficit in working memory ability when tested as adults. This mild insult early in gestation produced significant cognitive dysfunction that emerged with maturation, supporting the critical window of vulnerability during brain development.

A recent study found that teenagers with treatment-resistant depression can become symptom-free within six months of switching medications or combining a medicine switch with cognitive behavioral therapy. Those who showed improvement in symptoms early on were more likely to experience lasting benefits.
Researchers identified central, unifying elements of wisdom, including its uniqueness to humans, experiential nature, and personal quality. The study provides insight into the characteristic qualities of wisdom, shedding light on its distinctiveness from intelligence and spirituality.
Researchers found that older adults with late-life depression don't respond normally to emotional stimuli, making treatment more challenging. This study highlights the importance of emotion in understanding late-life depression and developing effective therapies.
Adolescents exposed to prenatal smoking are at a higher risk for use of all psychiatric drugs, especially those treating depression, ADHD, and addiction. Smoking exposure during pregnancy may interfere with brain development, leading to increased need for psychotropic medications in childhood and young adulthood.

These findings provide significant implications for risk identification and suggest that simpler measures of drinking behavior may be sufficient to capture the same ...
Professor Citrome's new theory of evidence-based flying aims to apply medical decision-making principles to frequent flying, analyzing flight delays and upgrade rates. By incorporating factors like airline competition, food service, and passenger loyalty, he hopes to develop a more precise predictive model for optimal flying decisions.
A recent study found that undiagnosed children with autistic traits display repetitive behaviors and social interaction impairments comparable to clinically diagnosed children. This highlights the need for expanded support services for these children, as they are often overlooked due to a gender bias in diagnosis.
Research finds childhood maltreatment can lead to shorter telomeres, a marker of biological aging, and increased risk of age-related diseases. The study suggests early developmental experiences may have profound effects on biology, influencing cellular mechanisms that accelerate aging.
Researchers found amyloid plaques in healthy elderly individuals with disrupted brain connections, similar to those with Alzheimer's disease. This suggests that Alzheimer's may begin quietly, eroding brain networks before symptoms appear.
A new 27-item questionnaire, the M-3 checklist, is a valid and effective tool to help primary care doctors screen patients for four common psychiatric illnesses.
