| Summary: | Background
Generalised joint hypermobility (GJH) is reportedly overrepresented among
clinical cases of attention deficit/hyperactivity disorder (ADHD), autism
spectrum disorder (ASD) and developmental coordination disorder (DCD). It
is unknown if these associations are dimensional and, therefore, also
relevant among non-clinical populations.
Aims
To investigate if GJH correlates with sub-syndromal neurodevelopmental
symptoms in a normal population.
Method
Hakim-Grahame's 5-part questionnaire (5PQ) on GJH, neuropsychiatric
screening scales measuring ADHD and ASD traits, and a DCD-related
question concerning clumsiness were distributed to a non-clinical, adult,
Swedish population (n=1039).
Results
In total, 887 individuals met our entry criteria. We found no
associations between GJH and sub-syndromal symptoms of ADHD, ASD or
DCD.
Conclusions
Although GJH is overrepresented in clinical cases with neurodevelopmental
disorders, such an association seems absent in a normal population. Thus,
if GJH serves as a biomarker cutting across diagnostic boundaries, this
association is presumably limited to clinical populations.
