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.

Children with autism often have problems developing motor skills, such as running, throwing a ball or even learning how to write. But scientists have not known whether those difficulties run in families or are linked to autism. New research at Washington University School of Medicine in St. Louis by Claudia List Hilton, PhD, points to autism as the culprit.

Neuroscientists at Washington University School of Medicine in St. Louis have identified the brain cells involved in alcohol-related blackouts and the molecular mechanism that appears to underlie them. Alcohol interferes with key receptors in the brain, which in turn manufacture steroids that inhibit long-term potentiation, a process that strengthens the connections between neurons and is crucial to learning and memory. 

The largest U.S. epidemiological study of Parkinson’s disease has found that the disease is more prevalent in the Midwest and the Northeast and is twice as likely to strike whites and Hispanics as blacks and Asians. Researchers analyzed data on more than 36 million Medicare recipients.

If you’re particularly good with puzzles or chess, the reason may be in your genes. A team of scientists, led by psychiatric geneticists at the School of Medicine, has gathered the most extensive evidence to date that a gene that activates signaling pathways in the brain influences one kind of intelligence. They have confirmed a link between the gene, CHRM2, and performance IQ, which involves a person’s ability to organize things logically.
