Abstract
In recent years, hypersomnia patients and researchers alike have increasingly discussed the possibility of heightened comorbidities, or co-occurrences, of autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) with the central disorders of hypersomnolence: idiopathic hypersomnia (IH) and narcolepsy (N). While a few scarce studies have investigated a link between ADHD and N, there has been no research on the co-occurrence of these conditions with IH. This study, using data from the Hypersomnia Foundation’s CoRDS Patient Registry, is the first to identify self-reported rates of ASD and ADHD diagnoses by people with idiopathic hypersomnia. Four chi-square tests were conducted to determine whether ASD or ADHD occurred at a significantly higher rate in IH than in the general population. People with IH reported ASD diagnoses at a frequency of 0.59% in the primary ASD test and 1.59% in the secondary test, while ADHD diagnoses were reported at a frequency of 25.84% in the primary ADHD test and 21.84% in the secondary test. The chi-square tests failed to confirm a statistically significant relationship, but the rate of ADHD diagnosis was high compared to general prevalence rates. Further research is required to obtain a more accurate measure of ASD’s co-occurrence with IH. The literature review for this study identified three commonalities shared by ASD, ADHD, and IH: excessive daytime sleepiness (EDS), memory and attention problems, and circadian rhythm abnormalities.
