Sequential withdrawal of stimulant drugs and use of behavior therapy with two hyperactive boys.

The separate and combined effects of stimulant drugs, placebos, and behavior therapy were investigated with two hyperactive boys. In each case, sequential replacement of drugs (Ritalin and Dexedrine) with placebos demonstrated placebo effects of the drugs; behavior therapy, alone and in combination with drugs, was effective in controlling hyperactive behaviors. Implications in regard to drugs as treatment of choice are discussed.
