tgkuo1 Kuo's List: Neurology

• In a study published online September 30 in The Lancet, investigators from the University of Cardiff in the United Kingdom say their findings, which show that ADHD has a genetic basis, suggest it should be classified as a neurodevelopmental and not a behavioral disorder.
• "We found that the most significant excess of these types of copy number variants was on a specific region of chromosome 16. This chromosomal region includes a number of genes, including one that affects brain development," said Dr. Thapar.
• The investigators note that despite epidemiologic evidence derived from twin studies showing high heritability and the fact that ADHD is often accompanied by learning disabilities, there is still a great deal of public misunderstanding about the disorder.
