- ADHD is characterized by inattention, hyperactivity, and impulsivity; stimulant medications like methylphenidate or amphetamine are common treatments.
- Approximately 40% of patients do not respond to stimulants, highlighting the need for predictors of efficacy to avoid expensive methods like neuroimaging.
- A naturalistic prospective observational study followed 36 medication-naïve adults with ADHD on stimulants for about 116 days, analyzing demographics, stimulant type, and clinical rating scales.
- Executive function impairment and better quality of life were identified as the best predictors for positive stimulant response.
- Higher scores on Adult Self-Report (ASR) Thought Problems, Withdrawn Problems, Internalizing Problems, and Intrusive Problems indicated lower stimulant efficacy.
- Poorer working memory and task monitoring also predicted lower response to stimulant medications.
- The findings suggest that clinical measures, including executive functioning, quality of life, and ASR profiles, can help predict stimulant response and reduce time to effective treatment.
