Research suggests a link between brain overgrowth and the onset of autistic characteristics, with behavioral symptoms occurring at around age one. This study supports previous findings on brain development in autistic children and may indicate an opportunity for early intervention.
Researchers have discovered a new approach to developing antidepressants by targeting novel brain molecules, which can lead to faster treatment and relief from depression. The study found that patients responded within two hours and 70% showed improvement within 24 hours.
A new study at the American College of Neuropsychopharmacology annual meeting found that psychotherapy, particularly cognitive therapy and cognitive behavioral therapy, significantly reduced PTSD symptoms when administered within a month after a traumatic event. The study suggests early intervention may prevent chronic PTSD development.
Scientists have identified small non-messenger RNA molecules, known as smnRNA, in genes associated with behavioral disorders. These findings suggest a new class of gene activity and regulation, potentially linked to conditions like Prader-Willi syndrome.
Researchers have found that administering n-acetyl cysteine can reverse changes in brain chemistry associated with cocaine craving. The study suggests a novel target for cocaine's action: the cysteine-glutamate antiporter, which pumps glutamate out of neurons.
A recent study found that individuals with two linked genetic variations are more likely to experience anxiety after consuming caffeine. The researchers validated a methodology that can identify individual differences in how people respond to major drugs, paving the way for future studies on other substances.
A large-scale study has identified genetic links to schizophrenia in European-American and African-American families. The research found a positive association between chromosome 15 and schizophrenia in European-Americans, but no such link in African-Americans.
A multi-site clinical trial found that citalopram, a popular adult anti-depressant, may help relieve suffering in children and adolescents with depression. The study showed significant improvement in mood among patients receiving the drug compared to those taking a placebo.
A follow-up study found that vagus nerve stimulation (VNS) improved symptoms in 60% of patients who had failed multiple medications, with 20% experiencing complete symptom disappearance. The technique has been approved for treating epilepsy and is currently being studied for its long-term benefits in depression.
