Read the transcript:

A wonderful question and a very concerning data regarding the relationship of ADHD and its comorbidity or mortality.

To frame this, a huge prospective study. It is a study involving over two and a half million individuals in Nordic countries and the long follow‑up from 1983 all the way to 2009. So we're at 25 years of follow‑up involved in this study.

Here's what they found. Having comorbidities with ADHD is lethal. Compared to individuals who have no comorbidities, just diagnosis of ADHD—ADHD alone versus individuals who have 2 comorbidities—the ones with 2 comorbidities had approximately 8‑fold higher mortality risk.

If we then compare individuals who have 4 or more comorbidities of ADHD to individuals who have no comorbidities, mortality risk is increased approximately 25‑fold.

So, having comorbidities, not only more morbidity or lower functioning, a greater risk for accidents, and seeking more medical attention, but the greatest of all consequences, dramatic increase in mortality.
