Attention Deficit Hyperactivity Disorder (ADHD) Practice Test

The correct answer reflects research findings indicating that approximately 25-30% of children with attention-deficit/hyperactivity disorder (ADHD) who are prescribed stimulant medications do not exhibit a significant positive response or may have adverse effects. This highlights the variability in treatment responses among individuals with ADHD, where the efficacy of stimulants can be influenced by genetic, environmental, and individual neurobiological factors.

In clinical practice, the effectiveness of stimulant medications can vary significantly, and some children may not respond to the drug in the desired manner. The figure of 25-30% suggests that a notable minority do not experience the anticipated therapeutic benefits, which is critical for healthcare professionals to consider when creating a treatment plan. Understanding that a substantial percentage of children may show no response or a negative response underscores the importance of ongoing evaluation and potential alternative therapies for those affected.
