ADHD is characterized by hyperactivity and deficits in learning and memory. Now, Eunjoon Kim and colleagues report that a polymorphism in the gene that encodes the adaptor protein GIT1 is linked to ADHD in humans. This polymorphism reduces GIT1 expression, and GIT1-deficient mice show ADHD-like behaviors that can be alleviated with the psychostimulant drugs used to treat human ADHD.
