Life expectancy/years of life lost in adults w ADHD in UK: matched cohort study

Original Article ↗ Hacker News Discussion ↗

Adults diagnosed with ADHD in the UK appear to lose roughly 7–9 years of life expectancy compared with the general population, according to a large matched cohort study, with researchers pointing to modifiable factors like smoking, accidents, substance abuse, suicide risk, and unmet physical and mental health needs rather than ADHD itself. Commenters link this excess mortality to chronic stress, stigma, underdiagnosis (especially in women), and a society whose institutions and expectations are built around neurotypical behavior. There is sharp debate over the role of stimulant and non-stimulant medications: many cite strong evidence that treatment reduces “unnatural” deaths, while others report severe side effects and worry about unknown long‑term risks.

Overview of study discussion

  • Study cited as showing UK adults with diagnosed ADHD lose ~6.8 years (men) and ~8.6 years (women) of life expectancy.
  • Several note confidence intervals overlap; unclear if male–female difference is statistically robust.
  • Many emphasize authors’ point that ADHD itself is unlikely sole cause; modifiable factors (smoking, accidents, mental/physical health, unmet treatment) are implicated.

Stress, executive dysfunction, and comorbidities

  • Multiple ADHD adults describe chronic stress from impaired executive function: knowing what to do but “can’t make yourself do it.”
  • This produces shame, social conflict, damaged relationships, and contributes to depression and anxiety.
  • Some use procrastination-induced anxiety as a “fuel” for productivity, which eventually breaks down physically and mentally.

Risk, accidents, and causes of early death

  • Commenters list higher rates of:
    • Car crashes and unintentional injuries.
    • Risky behaviors, substance abuse, and self-medication.
    • Suicide and possibly homicide victimization.
  • Impulsivity, poor conflict response, and higher risk tolerance are suggested mechanisms; some describe dangerously confrontational behavior in violent situations.

Medication: benefits, harms, and uncertainty

  • Several argue ADHD meds are among the most effective in psychiatry and reduce “unnatural deaths.”
  • Others report severe adverse experiences with amphetamines: personality changes, addiction-like behavior, cardiovascular issues.
  • Alternatives mentioned: methylphenidate, NRIs, alpha‑2A agonists, modafinil, non-stimulants (with their own cardiac risks).
  • Tension between short‑term gains and unclear long‑term outcomes; some call for decades‑long follow‑up studies.

Non‑drug strategies and “hacking” ADHD

  • Reported approaches: neurofeedback (one claims dramatic improvement), CBT, breathing exercises, walking, rigorous habit-building, simplifying lifestyle, early/partial retirement, aligning jobs with novelty and learning.
  • Mixed results: some feel nothing non‑pharmacological “moves the needle” enough.

Gender, subtypes, and diagnosis

  • Discussion that women are underdiagnosed; diagnosed women may represent more severe/inattentive cases.
  • Speculation that inattentive type may correlate with more depression/anxiety, hyperactive type with more lifelong physical activity.
  • No consensus; acknowledged as speculative.

Societal fit, stigma, and systems

  • Many argue modern systems (school, work, road rules, healthcare) are built around neurotypical brains, making ADHD a constant mismatch.
  • Culture of “just do the unpleasant thing” is seen as especially punishing; choice framed as “chronic stress vs. rejecting society.”
  • Strong reports of stigma from clinicians and pharmacists; underdiagnosis and provider bias seen as major barriers.
  • One clinician-like commenter calls adult ADHD “one of the most disabling” disorders and stresses huge economic costs and need for provider education.

Perceived strengths and evolutionary/speculative views

  • Some argue ADHD can confer advantages (fast reactions in emergencies, novel idea connections, historic “forager” benefits).
  • Others reject the “gift” framing, saying any strengths are overwhelmed by functional impairment and social penalties.
