The Dopamine Dilemma-Part II: Could Stimulants Cause Tolerance, Dependence, and Paradoxical Decompensation?

In this commentary, the author calls to attention that stimulants are commonly prescribed to children for years without seeming regard to the lack of studies on efficacy and safety during long-term use. The author examines evidence for stimulants losing efficacy over time and provides multiple possible mechanisms. The potential for paradoxical decompensation, an iatrogenic worsening of symptoms over time, is considered and discussed. Recommendations for detecting and responding to possible stimulant tolerance and dependence are provided.
