This paper reviews the current literature on twice-exceptional students who are dual diagnosed as having giftedness and attention deficit/hyperactivity disorder (ADHD). This area of research is warranted because giftedness and ADHD present similarly but have different ramifications for performance and outcomes. In addition, research inquiry and intervention can ease the frustration of those individuals who have both of these strengths and weaknesses. Giftedness and ADHD are examined in terms of identification of individual and dual diagnoses; performance of gifted students with ADHD, including underachievement and creativity; psychosocial outcomes; and interventions for students with giftedness/ADHD. Gaps in the literature and future directions are discussed.
