A post-mortem analysis of brain tissue from people who had been diagnosed with post-traumatic stress disorder (PTSD) may help explain enduring mysteries about the disorder, such as why women are more susceptible to it and whether a dampened immune system response plays a role in dealing with stress, a team has found.

Adapting a traditional endless runner video game and using a raccoon as the protagonist, researchers have developed a platform that allows the identification and evaluation of the degree of attention deficit hyperactivity disorder (ADHD) in children and adolescents.

Individuals with high ADHD-traits that do not meet the criteria for a diagnosis are less able to perform tasks involving attentional regulation or emotional control after a sleepless night than individuals with low ADHD-traits, a new study reports.

A pattern in how the brain breaks down tryptophan, a common amino acid consumed through food, was discovered.
