Washington, July 9 : Researchers from Vanderbilt University Medical Centre have uncovered a mechanism that might be responsible for attention deficit hyperactivity disorder (ADHD) in kids

The study suggests that a genetic change in the dopamine transporter – one of the brain''s dopamine-handling proteins might lead to ADHD.

While studying two brothers with ADHD, the researchers found that this altered function of the transporter gene variant supports a role for dopamine signalling in the disease.

Berlin - Before treatment begins for a child suspected of having an attention disorder, other possible maladies should be ruled out, according to Professor Andreas Warnke of the Berlin-based German Society for Child and Adolescent Psychiatry, Psychosomatics and Psychotherapy (DGKJP).

Warnke noted that some of the typical symptoms of Attention- Deficit and Hyperactivity Disorder (ADHD) could have other causes. If a child has difficulty concentrating, he said, it may be due to a developmental disorder such as dyslexia.
