I saw news of a publication in JAMA Psychiatry in November 2023 allegedly showing a 4% increase in cardiovascular disease with long term use of stimulants for the treatment of ADHD. I reviewed the article (and link is attached). It involved a a study of individuals in Sweden who used stimulants for the the treatment of ADHD for the 14 year period between January 1, 2007 and December 31, 2020. While a link was found, the "cardiovascular disease" found to be related (4% increase in occurrence) was only hypertension (high blood pressure). This was not a surprising finding since I believe the link between stimulants (like caffeine) and high blood pressure has been long known (and the article suggests the study subjects were on the stimulants when the blood pressure was tested).
Importantly, it found NO relationship between long term stimulant use for ADHD and increased risk or occurrence of arrhythmias, heart failure, ischemic heart disease, thromboembolic heart disease or stroke. As noted, only link (4% increase) was to high blood pressure.
My recommendation is that if you have concerns about side effects of any kind, you discuss them with the prescriber. My own discussions have revealed that the thinking seems to be that the benefits of the medications far outweigh this risk. I continue to advocate for the "3 legged stool" approach to management: 1. medication, 2. lifestyle modification at home, 3. support and reasonable accommodations at school (the most challenging "leg" for us). It has been hugely successful for us. My son went from an inability to focus and learn, being labelled as learning disabled, and being held in nearly daily from recess to getting accepted to his first choice college (with an academic scholarship to boot). While I will not ignore the results of this study, it is not a scary as the TV made it seem. Link attached. jamanetwork.com/journals/ja...
