An MRI scan often generates an ocean of data, most of which is never used. When overlooked data is analyzed using a new technique developed at the School of Medicine, they surprisingly reveal how many and which brain cells are present – and show where cells have been lost through injury or disease. The findings could lead to new treatments for a variety of brain diseases.

Why don’t you eat your friend’s lunch when you are hungry? Cognitive control. Researchers at the School of Engineering & Applied Science and Arts & Sciences at Washington University in St. Louis are working together to better understand this aspect of cognition.

Parkinson’s disease is caused by the injury or death of brain cells known as dopaminergic neurons. A new School of Medicine study shows that people who take drugs that suppress the immune system are less likely to develop the disease, which is characterized by difficulty with movement.

Using MRIs, researchers at the School of Medicine have identified areas in the brains of children with Tourette’s syndrome that appear markedly different from the same areas in the brains of children who don’t have the neuropsychiatric disorder. The findings were published online Oct. 25 in the journal Molecular Psychiatry.

Scientists have linked mutations in a single gene to autism in people who have a rare tumor syndrome typically diagnosed in childhood. The findings, in patients with neurofibromatosis type 1 (NF1), may lead to a better understanding of the genetic roots of autism in the wider population.

Premature babies are at an increased risk for developing autism spectrum disorder. But a small study indicates that preemies who avoid eye contact are less likely to demonstrate symptoms of autism at age 2 than preemies who maintain eye contact during early interactions, according to new research at the School of Medicine.

Evaluating military personnel with blast-related mild traumatic brain injuries, researchers have found that early symptoms of post-traumatic stress, such as anxiety, emotional numbness, flashbacks and irritability, are the strongest predictors of later disability. The study was led by the School of Medicine.

Washington University School of Medicine recently teamed up with the Saint Louis Art Museum and the university’s Mildred Lane Kemper Art Museum to scan some very unusual patients: three Egyptian mummies.

Young adults with autistic tendencies don’t often engage in social or binge drinking, but if they drink, they are slightly more likely than their peers to develop alcohol problems, according to new research from Duneesha De Alwis (right) and Arpana Agrawal at the School of Medicine.

A protein required to regrow injured peripheral nerves has been identified by researchers at Washington University School of Medicine in St. Louis. The finding, in mice, has implications for improving recovery after nerve injury in the extremities. It also opens new avenues of investigation toward triggering nerve regeneration in the central nervous system, notorious for its inability to heal.
