A new study finds that black girls are 50% more likely to exhibit bulimic behavior, including binging and purging, compared to white girls. The study also reveals that girls from low-income families are significantly more likely to experience bulimia than their wealthier peers.
Researchers discovered an abnormality in the brains of adolescent boys with attention deficit hyperactivity disorder, particularly in the anterior cingulate cortex. This region normally activates when a reward stops, but in boys with ADHD, it fails to do so, leading to continued activation and impulsive behavior.

The study found that nearly half of patients with this condition develop a neurodegenerative disease within 12 years of diagnosis.
A study published in Neurology found that people with REM sleep behavior disorder have an increased risk of developing neurodegenerative diseases like dementia and Parkinson's. The five-year risk was estimated to be 18%, while the 10-year and 12-year risks were 41% and 52%, respectively.
A recent study used Diffusion Tensor Imaging (DTI) to assess white-matter microstructure in youth with and without histories of heavy prenatal alcohol exposure. The findings show that alcohol can damage the microstructural integrity of fetal cerebral white matter, particularly in the frontal and occipital lobes, which are relevant for ...
Researchers identified FKBP12, a protein regulating mTOR activity, as key to understanding autism and OCD in mice. The study found enhanced synaptic plasticity and contextual memory but also perseverative and repetitive behaviors, common in individuals with these disorders.
Researchers estimate RASD affects 25-30% of children with an autistic disorder. Children with RASD typically develop normally until 18-24 months, then regress and lose previously acquired skills. Identifying early signs is crucial to address potential neurological development issues.

Researchers used Palm Pilots as electronic diaries to analyze mood variability in BPD patients, finding significant instability in positive and negative moods. The devices helped bridge the communication gap between therapists and patients.
Researchers have uncovered structural features of the brain that may contribute to the development of ADHD. The study used a new analysis tool to examine shape differences in the brains of children with ADHD and found significant abnormalities in boys, but not girls.
Researchers found that high doses of cortisone can prevent negative consequences of stress exposure, including increased startle response and behavioral freezing. This finding suggests a possible treatment option for post-traumatic stress disorder (PTSD) in its acute phase.
Researchers have identified three new candidate genes for schizophrenia that may contribute to a better understanding of the disease. These genes are associated with brain function and are present in only 1% of schizophrenia patients, suggesting they play a significant role in its development.
Researchers found a correlation between motor task performance and myelin integrity, peaking in middle age before declining. Myelin breakdown may underlie cognitive decline and physical skills erosion, but therapeutic interventions could slow the process.
