In the present study, plasma DBH activity and urinary HVA levels were measured in 19 autistic and 15 normal children. DBH activity was significantly elevated in the 8 less retarded autistic patients. In this subgroup, a negative correlation was found between plasma DBH and urinary HVA levels. These results support the hypothesis of a possible involvement of brain catecholamine dysfunction in the production of autistic symptoms.
