METHODS Two cross-sectional studies were performed in children and adults whose intelligence quotient (IQ) had been previously evaluated using Raven's Progressive Matrices (RPM) test. Seventy-seven adults displaying IQ scores above the 98th percentile were assessed using the Adult Self-Report Scale (ASRS-18) for signs of ADHD and a modified Waldrop scale for minor physical anomalies (MPAs). Thirty-nine children (grades 1-5) exhibiting IQ scores above the 99th percentile, as well as an equally matched control group, were assessed for ADHD by teachers using the Swanson, Nolan and Pelham IV Rating Scale (SNAP-IV) as used in the NIMH Collaborative Multisite Multimodal Treatment Study of Children with Attention-Deficit/Hyperactivity Disorder (MTA-SNAP-IV). RESULTS In gifted adults, the frequency of ADHD-positive cases was 37.8%, and the t...

Results: In gifted adults, the frequency of ADHD-positive cases was 37.8%, and the total MPA score was significantly associated with ADHD (p o 0.001). In children, the ADHD-positive case frequency was 15.38% in the gifted group and 7.69% in the control group (odds ratio [OR] = 2.18, p = 0.288). Conclusions: The high frequency of ADHD symptoms observed, both in gifted adults and in gifted (and non-gifted) children, further supports the validity of this diagnosis in this population. Furthermore, the significant association between MPAs and ADHD suggests that a neurodevelopmental condition underlies these symptoms.

To evaluate the frequency and pattern of symptoms of ADHD in intellectually gifted
individuals during two distinct moments of their life cycle, using standardized scales. In
addition, we tested whether an association between minor physical anomalies and ADHD
may be found in intellectually gifted adults. METHODS: Two cross-sectional studies
were conducted in participants who had been previously evaluated for IQ’s with Raven’s
Progressive Matrices: (1) Mensa: This study included 77 adult participants (22% women)
recruited from the records of active members of Mensa Brazil living in São Paulo. The
ASRS-18 and a modified version of Waldrop’s scale for minor physical anomalies were
applied; (2) Elementary school: All children from first to fifth year of elementary school
(6-11 years old) who were above the 99th IQ percentile (n=39) were included. The control
group included 39 classmates randomly selected among those below the 90th IQ percentile
matched for age and sex. Teachers rated participants using MTA-SNAP-IV. RESULTS:
(1) Mensa: The estimated frequency of ADHD was 37.8%. The total number of minor
physical anomalies was significantly associated with ADHD (p<0.001) and 8 of the 36
evaluated signs showed this association individually (p<0.05). (2) Elementary school: A
Rate of 25.6% of ADHD was found in the control group and 17.9% in the group of talented
individuals (OR=0.64, p=0.58). CONCLUSION: Although our data do not unequivocally
confirm the higher prevalence of ADHD in gifted individuals throughout their life cycles,
they suggest the validity of the diagnosis in this population. An association between
ADHD cases and minor physical anomalies was found in the Mensa population, further
supporting the notion that ADHD is a neurodevelopmental condition.
