A rigorous analysis of numerous studies concludes that a part of the brain traditionally associated with movement is abnormal in children with developmental language impairments, according to Georgetown University Medical Center neuroscientists. The discovery has the potential to improve both the diagnosis and treatment of the language difficulties.
The researchers investigated brain abnormalities in developmental language disorder. This condition, which impacts the development of various aspects of language, is about as common as attention-deficit/hyperactivity disorder (ADHD) and dyslexia, and more prevalent than autism. The scientists found that abnormalities occurred specifically in the anterior neostriatum within the basal ganglia, a structure found deep in the brain.
They describe their findings in Nature Human Behaviour on March 15.
