Motor control in ability to perform everyday and spare-time activities was assessed at 11 to 12 years of age in 10 boys with deficits in attention, motor control and perception (DAMP) and compared with a group of 20 boys without DAMP. The study group had been diagnosed with DAMP at 5 to 8 years of age. Individually, the boys with DAMP had a significantly higher total score on a Movement Assessment Battery, indicating poor motor performance, than the boys without DAMP (p<.001). None participated in team sports, and their choice of everyday and spare-time activities were different from normal. No improvement in motor control with age was observed in boys with DAMP. 
COMMENT. DAMP is a diagnostic term used predominantly in Scandinavia to describe the signs of minimal brain dysfunction that are frequently found in children with ADHD and that overlap with the developmental coordination disorder (DCD) listed in the US DSM-IV. This study demonstrates the importance of the neurologic examination in children with ADHD, so that therapeutic intervention with occupational and physical therapy can be instituted at an early age. The “clumsy” child with ADHD has low self esteem, unless appropriate physical education activities and counseling are recommended early.
