Could ADHD drugs reduce the risk of early death? Unpacking the findings from a new Swedish study

Attention-deficit hyperactivity disorder (ADHD) can have a considerable impact on the day-to-day functioning and overall wellbeing of people affected. It causes a variety of symptoms including difficulty focusing, impulsivity and hyperactivity.

For many, a diagnosis of ADHD, whether in childhood or adulthood, is life changing. It means finally having an explanation for these challenges, and opens up the opportunity for treatment, including medication.

Although ADHD medications can cause side effects, they generally improve symptoms for people with the disorder, and thereby can significantly boost quality of life.

Now a new study has found being treated for ADHD with medication reduces the risk of early death for people with the disorder. But what can we make of these findings?

A large study from Sweden

The study, published this week in JAMA (the prestigious journal of the American Medical Association), was a large cohort study of 148,578 people diagnosed with ADHD in Sweden. It included both adults and children.

In a cohort study, a group of people who share a common characteristic (in this case a diagnosis of ADHD) are followed over time to see how many develop a particular health outcome of interest (in this case the outcome was death).

For this study the researchers calculated the mortality rate over a two-year follow up period for those whose ADHD was treated with medication (a group of around 84,000 people) alongside those whose ADHD was not treated with medication (around 64,000 people). The team then determined if there were any differences between the two groups.

What did the results show?

The study found people who were diagnosed and treated for ADHD had a 19% reduced risk of death from any cause over the two years they were tracked, compared with those who were diagnosed but not treated.

In understanding this result, it’s important – and interesting – to look at the causes of death. The authors separately analysed deaths due to natural causes (physical medical conditions) and deaths due to unnatural causes (for example, unintentional injuries, suicide, or accidental poisonings).

The key result is that while no significant difference was seen between the two groups when examining natural causes of death, the authors found a significant difference for deaths due to unnatural causes.

So what’s going on?

Previous studies have suggested ADHD is associated with an increased risk of premature death from unnatural causes, such as injury and poisoning.

On a related note, earlier studies have also suggested taking ADHD medicines may reduce premature deaths. So while this is not the first study to suggest this association, the authors note previous studies addressing this link have generated mixed results and have had significant limitations.

In this new study, the authors suggest the reduction in deaths from unnatural causes could be because taking medication alleviates some of the ADHD symptoms responsible for poor outcomes – for example, improving impulse control and decision-making. They note this could reduce fatal accidents.

The authors cite a number of studies that support this hypothesis, including research showing ADHD medications may prevent the onset of mood, anxiety and substance use disorders, and lower the risk of accidents and criminality. All this could reasonably be expected to lower the rate of unnatural deaths.

Strengths and limitations

Scandinavian countries have well-maintained national registries that collect information on various aspects of citizens’ lives, including their health. This allows researchers to conduct excellent population-based studies.

Along with its robust study design and high-quality data, another strength of this study is its size. The large number of participants – almost 150,000 – gives us confidence the findings were not due to chance.

The fact this study examined both children and adults is another strength. Previous research relating to ADHD has often focused primarily on children.

One of the important limitations of this study acknowledged by the authors is that it was observational. Observational studies are where the researchers observe and analyse naturally occurring phenomena without intervening in the lives of the study participants (unlike randomised controlled trials).

The limitation in all observational research is the issue of confounding. This means we cannot be completely sure the differences between the two groups observed were not either partially or entirely due to some other factor apart from taking medication.

Specifically, it’s possible lifestyle factors or other ADHD treatments such as psychological counselling or social support may have influenced the mortality rates in the groups studied.

Another possible limitation is the relatively short follow-up period. What the results would show if participants were followed up for longer is an interesting question, and could be addressed in future research.

What are the implications?

Despite some limitations, this study adds to the evidence that diagnosis and treatment for ADHD can make a profound difference to people’s lives. As well as alleviating symptoms of the disorder, this study supports the idea ADHD medication reduces the risk of premature death.

Ultimately, this highlights the importance of diagnosing ADHD early so the appropriate treatment can be given. It also contributes to the body of evidence indicating the need to improve access to mental health care and support more broadly.The Conversation

    Winning The Biological Arms Race

    The human immune system (and indeed, other immune systems, but we are all humans here, after all) is in a constant state of war with pathogens, and that war is a constant biological arms race:

    • We improve our defenses and destroy the attackers; the 1% of pathogens that survived now “know” how to counter that trick.
    • The pathogens wreak havoc in our systems; the n% of us that survive now have immune systems that “know” how to counter that trick.

    Vaccines are a mighty tool in our favor here, because they’re the technology that stops our n% from also being a very low number.

    With vaccines, we can effectively pass on established defenses onto the population at large, as this cute video explains very well and very simply in 57 seconds:

    Click Here If The Embedded Video Doesn’t Load Automatically!

    The problem with vaccines

    The problem is that this accelerates the arms race. It’s like a chess game where we are able to respond to every move quickly (which is good for us), and/but this means passing the move over to our opponent sooner.

    That problem’s hard to avoid, because the alternative has always been “let people die in much larger numbers”.

    Traditional vs mRNA vaccines

    A quick refresher before we continue to the big news of the day:

    • Traditional vaccines use a disabled version of a pathogen to trigger an immune response that will teach the body to recognize the pathogen ready for when the full version shows up
    • mRNA vaccines use a custom-made bit of genetic information to tell the body to make its own harmless fake pathogen and then respond to the harmless fake pathogen it made.

    Note: this happens independently of the host’s DNA, so no, it does not change your DNA

    See also: The Truth About Vaccines

    Here’s a more detailed explainer (with a helpful diagram) using the COVID mRNA vaccine as an example:

    Genome.gov | How does an mRNA vaccine work?

    However, this still leaves us “chasing strains”, because as the pathogen (in this case, a virus) adapts, the vaccine has to be updated too, hence all the boosters.

    This is a lot like a security update for your computer’s antivirus software. They’re annoying, but they do an important job.

    No more “chasing strains”

    The press conference soundbite on this sums it up well:

    ❝Scientists at UC Riverside have demonstrated a new, RNA-based vaccine strategy that is effective against any strain of a virus and can be used safely even by babies or the immunocompromised.❞

    ~ Jules Bernstein

    Read in full: Vaccine breakthrough means no more chasing strains

    You may be wondering: what makes this one effective against any strain?

    ❝What I want to emphasize about this vaccine strategy is that it is broad.

    It is broadly applicable to any number of viruses, broadly effective against any variant of a virus, and safe for a broad spectrum of people. This could be the universal vaccine that we have been looking for.

    Viruses may mutate in regions not targeted by traditional vaccines. However, we are targeting their whole genome with thousands of small RNAs. They cannot escape this.❞

    ~ Dr. Rong Hai

    Importantly, this means it can be applied not just to one disease, let alone just one strain of COVID. Rather, it can be used for a wide variety of viruses that have similar viral functions—COVID / SARS in general, including influenza, and even viruses such as dengue.

    How it does this: the above article explains in more detail, but in few words: it targets tiny strings of the genome that are present in all strains of the virus.

    Illustrative example: if you wanted to block 10almonds (please don’t), you could block our email address.

    But if we were malicious (we’re not) we could be sneaky and change it, so you’d have to block the new one, and the cycle repeats.

    But if you were block all emails containing the tiny string of characters “10almonds”, changing our email address would no longer penetrate your defenses.

    Now imagine also blocking strings such as “One-Minute Book Review” and “Today’s almonds have been activated by” and other strings we use in every email.

    Now multiply this by thousands of strings (because genomes are much larger than our little newsletter), and you see its effectiveness!

    Great! How can I get this?

    It’s still in the testing stages for now; this is “breaking news” science, after all.

    The study itself

    …is paywalled for now, sadly, but if you happen to have institutional access, here it is:

  • Celery vs Carrot – Which is Healthier?

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Our Verdict

    When comparing celery to carrot, we picked the carrot.

    Why?

    In terms of macros, carrot has more protein, carbs, and fiber, and is thus the “most food per food” option. The carb:fiber ratio is such that they have about the same glycemic index (when raw, anyway).

    In the category of vitamins, celery has more of vitamins B9 and K, while carrot has more of vitamins A, B1, B2, B3, B5, B6, C, E, and choline. An easy win for carrot here.

    When it comes to minerals, celery has more calcium and selenium, while carrot has more copper, iron, magnesium, manganese, phosphorus, potassium, and zinc. Another clear win for carrot.

    In short, both are very respectable foods, but carrot simply has more in it, and it’s all good.

    Enjoy!

  • White Beans vs Pinto Beans – Which is Healthier?

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Our Verdict

    When comparing white beans to pinto beans, we picked the pinto beans.

    Why?

    Both are good and both have their strengths! But we say the pinto beans come out on top in total:

    In terms of macros, the two beans are about equal in protein and carbs, while pinto beans have notably more fiber. White beans were already good, but we say having 1.5x the fiber makes pinto beans the winner in this category.

    In the category of vitamins, white beans are not higher in any vitamins, while pinto beans have more of vitamins B1, B2, B3, B6, B7, B9, and C, making for a 7:0 win for pinto beans. It’s worth mentioning that both beans are equal in vitamins B5, E, K, and choline, though. Still, pinto beans win easily on the strength of those 7 vitamins they have more of.

    When it comes to minerals, white beans have more calcium, copper, iron, magnesium, manganese, potassium, and zinc, while pinto beans have more phosphorus and selenium, making for a win for white beans this time.

    Adding up the sections makes for an overall win for pinto beans, but by all means, enjoy either or both; diversity is good!

  • Krill Oil vs Fish Oil – Which is Healthier?

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Our Verdict

    When comparing krill oil to fish oil, we picked the krill oil.

    Why?

    Both of these products are good sources of omega-3 fatty acids EPA and DHA, and for the specific brand depicted above, in both cases 2 softgels will give you the recommended daily amount (which is generally held to be 250–500mg combined omega-3s per day).

    This brand’s fish oil gives more (640mg combined omega-3s per 2 softgels, to the same brand’s krill oil’s 480mg per 2 softgels), but since the krill oil is already in the high end of RDA territory, the excess beyond the RDA is not helpful, and not a huge factor. More quantity is not always better, when the body can only process so much at a time.

    However, the krill oil gives some extra things that the fish oil doesn’t:

    • Astaxanthin, a “super-antioxidant”
    • and neuroprotectant, heart-healthy phospholipids

    Additional considerations

    We have declared “the winner” based on health considerations only. That’s a sticking point for us in all our writings; we’ll occasionally look at and mention other factors, but we know that health is what you’re here for, so that’s what we’ll always treat as most critical.

    However, in case these factors may interest you and/or influence you to one or the other:
    •⁠ ⁠The fish oil is about 30% cheaper financially
    •⁠ ⁠The krill oil is a lot more sustainable environmentally

  • The Sleep Solution – by Dr. Chris Winter

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    This book’s blurb contains a bold claim:

    ❝If you want to fix your sleep problems, Internet tips and tricks aren’t going to do it for you. You need to really understand what’s going on with your sleep—both what your problems are and how to solve them.❞

    So, how well does it deliver, on the strength of being a whole book rather than an Internet article?

    Well, for sure we wouldn’t have the room to include all the information that Dr. Winter does, in one of our main feature articles here (we’d need to spread it out over several weeks, at least).

    He examines very thoroughly what is going on with sleep, sleep disturbance, and sleep deprivation. What’s going on with the different phases of sleep (far more than your phone’s sleep app will), and how imbalances in these can cause problems.

    While the usual sleep hygiene tips do get a mention, he broadly assumes we know that part already. Instead, he focuses on aligning as many components as possible of our rich and interesting circadian rhythm. Yes, even if that means clawing our way out of insomnia and/or a bad sleep schedule (or lack of coherent sleep schedule) first. He gives plenty of practical advice on how to do that.

    Bottom line: if you’d like to more deeply understand sleep, what is or isn’t wrong with yours, and how you can fix it, this book is a great resource.

    Hello, dear reader!

    This is my first column for Healthy Debate as a Patient Navigator. This column will be devoted to providing patients with information to help them through their journey with the health-care system and answering your questions.

    Here’s a bit about me: I have been a patient partner at The Ottawa Hospital and Ottawa Hospital Research Institute since 2017, and have joined a variety of governance boards that work on patient and caregiver engagement such as the Patient Advisors Network, the Ontario Health East Region Patient and Family Advisory Council and the Equity in Health Systems Lab.

    My journey as a patient partner started much before 2017 though. When I was a teenager, I was diagnosed with a cholesteatoma, a rare and chronic disease that causes the development of fatty tumors in the middle ear. I have had multiple surgeries to try to fix it but will need regular follow-ups to monitor whether the tumor returns. Because of this, I also live with an invisible disability since I have essentially become functionally deaf in one ear and often rely on a hearing aid when I navigate the world.

    Having undergone three surgeries in my adolescent years, it was my experience undergoing surgery for an acute hand and wrist injury following a jet ski accident as an adult that was the catalyst for my decision to become a patient partner. There was an intriguing contrast between how I was cared for at two different health-care institutions, my age being the deciding factor at which hospital I went to (a children’s hospital or an adult one).

    The most memorable example was how, as a teenager or child, you were never left alone before surgery, and nurses and staff took all the time necessary to comfort me and answer my (and my family’s) questions. I also remember how right before putting me to sleep, the whole staff initiated a surgical pause and introduced themselves and explained to me what their role was during my surgery.

    None of that happened as an adult. I was left in a hallway while the operating theater was prepared, anxious and alone with staff walking by not even batting an eye. My questions felt like an annoyance to the care team; as soon as I was wheeled onto the operating room table, the anesthetist quickly put me to sleep. I didn’t even have the time to see who else was there.

    Now don’t get me wrong: I am incredibly appreciative with the quality of care I received, but it was the everyday interactions with the care teams that I felt could be improved. And so, while I was recovering from that surgery, I looked for a way to help other patients and the hospital improve its care. I discovered the hospital’s patient engagement program, applied, and the rest is history!

    Since then, I have worked on a host of patient-centered policy and research projects and fervently advocate that surgical teams adopt a more compassionate approach with patients before and after surgery.

    I’d be happy to talk a bit more about my journey if you ask, but with that out of the way … Welcome to our first patient navigator column about patient engagement.

    Conceptualizing the continuum of Patient Engagement

    In the context of Canadian health care, patient engagement is a multifaceted concept that involves active collaboration between patients, caregivers, health-care providers and researchers. It involves patients and caregivers as active contributors in decision-making processes, health-care services and medical research. Though the concept is not new, the paradigm shift toward patient engagement in Canada started around 2010.

    I like to conceptualize the different levels of patient engagement as a measure of the strength of the relationship between patients and their interlocutors – whether it’s a healthcare provider, administrator or researcher – charted against the duration of the engagement or the scope of input required from the patient.

    Defining different levels of Patient Engagement

    Following the continuum, let’s begin by defining different levels of patient engagement. Bear in mind that these definitions can vary from one organization to another but are useful in generally labelling the level of patient engagement a project has achieved (or wishes to achieve).

    Patient involvement: If the strength of the relationship between patients and their interlocutors is minimal and not time consuming or too onerous, then perhaps it can be categorized as patient involvement. This applies to many instances of transactional engagement.

    Patient advisory/consulting: Right in the middle of our continuum, patients can find themselves engaging in patient advisory or consulting work, where projects are limited in scope and duration or complexity, and the relationship is not as profound as a partnership.

    Patient partnership: The stronger the relationship is between the patient and their interlocutor, and the longer the engagement activity lasts or how much input the patient is providing, the more this situation can be categorized as patient partnership. It is the inverse of patient involvement.

    Examples of the different levels of Patient Engagement

    Let’s pretend you are accompanying a loved one to an appointment to manage a kidney disease, requiring them to undergo dialysis treatment. We’ll use this scenario to exemplify what label could be used to describe the level of engagement.

    Patient involvement: In our case, if your loved one – or you – fills out a satisfaction or feedback survey about your experience in the waiting room and all that needed to be done was to hand it back to the clerk or care team, then, at a basic level, you could likely label this interaction as a form of patient involvement. It can also involve open consultations around a design of a new look and feel for a hospital, or the understandability of a survey or communications product. Interactions with the care team, administrators or researchers are minimal and often transactional.

    Patient advisory/consulting: If your loved one was asked for more detailed information about survey results over the course of a few meetings, this could represent patient advisory/consulting. This could mean that patients meet with program administrators and care providers and share their insights on how things can be improved. It essentially involves patients providing advice to health-care institutions from the perspective of patients, their family members and caregivers.

    Patient advisors or consultants are often appointed by hospitals or academic institutions to offer insights at multiple stages of health-care delivery and research. They can help pilot an initiative based on that feedback or evaluate whether the new solutions are working. Often patient advisors are engaged in smaller-term individual projects and meet with the project team as regularly as required.

    Patient partnership: Going above and beyond patient advisory, if patients have built a trusting relationship with their care team or administrators, they could feel comfortable enough to partner with them and initiate a project of their own. This could be for a project in which they study a different form of treatment to improve patient-centered outcomes (like the time it takes to feel “normal” following a session); it could be working together to identify and remove barriers for other patients that need to access that type of care. These projects are not fulfilled overnight, but require a collaborative, longstanding and trusting relationship between patients and health-care providers, administrators or researchers. It ensures that patients, regardless of severity or chronicity of their illness, can meaningfully contribute their experiences to aid in improving patient care, or develop or implement policies, pilots or research projects from start to finish.

    It is leveraging that lived and living experience to its full extent and having the patient partner involved as an equal voice in the decision-making process for a project – over many months, usually – that the engagement could be labeled a partnership.

    Last words

    The point of this column will be to answer or explore issues or questions related to patient engagement, health communications or even provide some thoughts on how to handle a particular situation.

    I would be happy to collect your questions and feedback at any time, which will help inform future columns. Just email me at max@le-co.ca or connect with me on social media (Linked In, X / Twitter).
