The relationship between stimulant medication and tics.
Clinical evidence supports the observation that stimulant drugs increase the severity of tics in 25% to 50% of patients with TS, and occasionally can precipitate TS in a patient who did not previously manifest symptoms of this disorder. As ADD is frequently associated with TS, the clinician is often faced with a dilemma. A conservative approach to the use of stimulant medication, stringent criteria for its use, adequate counseling of the child and parents, and a thorough cost-benefit analysis before initiating treatment are required. Behavior management and environmental manipulation can be useful techniques with the child with ADD, and should be tried before medication is considered.
