Hyperkinetic syndrome: The role of depression.

The hyperkinetic syndrome is one of many manifestations of minimal brain dysfunction and emotional distrubance. Both physical and psychologic factors can be seen in its etiology. Depression has often been found to be related to hyperkinesis. The children described in this study give ample support to the frequency of this relationship. Some preliminary hypotheses are also drawn about the dynamics of the relationship between depression and the hyperkinetic syndrome.
