Attention Deficit and Hyperactive Disorder (ADHD) and Autism Spectrum Disorders
(ASD) are frequent comorbid neurodevelopmental conditions and the overlap
between both disorders remains to be delineated. A more complete understanding
of the shared genetic and environmental factors is needed. Using a family-based
method, we evaluated the risk of ADHD in a group of relatives with an ASD
proband (ASD-) and a group of relatives with an ASD and ADHD proband (ASD+). We
enrolled 1245 individuals in the study: 499 probands, their 746 first-degree
relatives and 140 controls. We used a multivariate generalized estimating
equation (GEE) model, in which the dependent variable was the ADHD diagnosis in
the relatives and the independent variable the ASD+ or ASD- in probands. We
adjusted for sociodemographic factors (age, sex, IQ) and for the nature of the
familial relationship with the affected proband (parent or sibling). Among the
probands, there were 287 ASD- and 212 ASD+ individuals. ADHD was more frequent
in relatives (19%) than in the control group (7%) (p = 0.001). The risk of ADHD
was higher in the ASD+ relatives group than in the ASD- relatives group (GEE
model OR 1.58 [95% CI 1.04-2.38], p = 0.032). This result was found in parents
(OR 1.96 [95% CI 1.14-3.36], but not in siblings (OR 1.28 [95% CI 0.84-1.94],
p = 0.434). Our study provides a representative estimate of the family
distribution of ADHD in relatives of ASD probands but supports the modest effect
of shared genetic and environmental factors between both disorders.
