People diagnosed with type 2 diabetes before age 20 were about twice as likely to have an ADHD diagnosis as young people without diabetes, according to an analysis of U.S. patient records presented at this year's European Association for the Study of Diabetes (EASD) meeting in Milan. Among those diagnosed with diabetes as teenagers or younger, 14.4% had ADHD, compared with 6.9% of similarly aged peers. Autism showed an even wider gap, at 5.72% vs. 1.79%.
The findings come from a conference abstract and have not been published in a peer-reviewed journal. They show an association, not proof that ADHD or autism causes diabetes, or the reverse.
