Neuroimaging reveals lower activation in the dorsolateral prefrontal cortex and angular gyrus in teenage girls with conduct disorder. Findings suggest that a reduction in prefrontal brain regions and functional connectivity during effortful emotional regulations contribute to behaviors associated with antisocial behavior in teenage girls.
According to researchers, children who carry the APOE4 gene and who are exposed to air pollution have higher behavior problem scores and their attention capacity was slower to develop.
Assessing a child's exposure to air pollution on a monthly basis from conception to the age of 8.5, researchers found the greater the exposure to air pollution before the age of 5, the greater the alteration in brain structure by preadolescence.
A new study could help explain why preterm babies are at higher risk of neurodevelopmental disorders.
The right putamen, a brain area linked to reward, motivation, and feelings of pleasure, is smaller in children with a genetic risk factor for depression. Previous studies implicated reduced putamen volume with anhedonia, which is often associated with depression, suicidal behaviors, and psychosis.
A new study reports obese teens have disrupted connectivity between numerous areas of the brain involved in appetite regulation.
Researchers report preteens who like to experiment and engage in new experiences have stronger neural connections and brain processes than those who don't.
Stress can have an impact on voice disorders. Researchers found those with higher salivary cortisol levels also exhibited brain activity that impacted the larynx. Those who were more introverted were more likely to have stress reactions related to speech.
Researchers identified 48 common genetic variants that appear to play a role in the size of the brainstem and other subcortical structures. Forty of the variants were novel. The findings also revealed 199 genes related to the variants which regulate brain development and susceptibility to neurological disorders.
A new study reports children and teens who face chronic bullying have altered brain structure, as well as problems with anxiety and depression. Researchers found those who were bullies had structural changes to the putamen and caudate, contributing to the development of anxiety related behaviors and emotional processing.
Chronic stress can affect a person's health and mental well being. Due to the COVID-19 virus, chronic stress is on the rise worldwide. Researchers examine the general and psychological health implications of chronic stress and suggest some methods we can adopt to keep our stress levels in check.
