It was a delight speaking to @davetuller1.bsky.social about our recent paper lead by @simonmcg.bsky.social with @charliehillier.bsky.social, @tschei.bsky.social, Joshua Dibble and Arild Angelsen. We discuss why this is solid evidence for two age peaks in ME/CFS onset and the biological implications.

A great interview with Dr Audrey Ryback about the recent finding of two consistent age peaks in many European countries for the onset of ME/CFS. Follow-up work using the @actionforme.bsky.social Big Survey data hopes to give insight into early vs late onset differences @aryback.bsky.social.

Blog about the recent study finding evidence across Europe for ME/CFS peaking at two different ages, a v unusual feature. The peak ages of 1about 6 and late 30s is a unique combo even among diseases with two, and could be a clue to the biology of ME/CFS. mecfsresearchreview.me/2026/04/15/m...

ME/CFS onset had two peaks, which may be a clue to causes

A new study strengthens the findings that ME/CFS is a disease with a highly unusual feature. Analysis of survey data on patients across Europe found there are two peak ages for getting ME/CFS, arou…

Read our paper with @simonmcg.bsky.social @aryback.bsky.social here! We report that ME/CFS has a bimodal age onset pattern with peaks in adolescence and early middle age. It is unusual for a disease to have more than one onset peak, a feature that may provide a clue into the causes of the illness.

Incidence age is bimodal for Myalgic Encephalomyelitis/Chronic Fatigue Syndrome, with higher severity burden for early onset disease by @simonmcg.bsky.social et al academic.oup.com/ooim/advance... "early onset peak with a mean of 16.0 years old...& a late onset peak at 36.6 years old" #MEcfs #PwME

Abstract
Myalgic Encephalomyelitis, or Chronic Fatigue Syndrome (ME/CFS), is a disease of uncertain origin. Studies of Norwegian health records have suggested that ME/CFS incidence across age groups is bimodal–a characteristic that could provide insight into the aetiology of the disease. Here, we analysed survey data from over 9,000 respondents with ME/CFS from 10 European countries, and observe an early onset peak with a mean of 16.0 years old (standard deviation [sd]: 4.3) and a late onset peak at 36.6 years old (sd: 10.5). Statistical support for multimodal onset age was evident in 7 of the 10 countries examined. Infection as a trigger for ME/CFS is 10 percentage points higher among early compared to late onset disease (P = 2.1 × 10−13). Early onset ME/CFS was associated with greater odds of being severely or very severely affected (OR = 2.15, 95% CI [1.84—2.51], p < 2 × 10−16). Those with first degree relatives with ME/CFS had greater odds of early than late onset ME/CFS (OR = 1.43, 95% CI [1.25—1.63], P = 4.4 × 10−07). We further validated our findings in a UK dataset where we replicated bimodal onset age and observed significantly greater odds of glandular fever/infectious mononucleosis as a trigger in early onset cases (OR = 2.32, 95% CI [1.99—2.71], P = 2.4 × 10−24). Our findings suggest that incidence of ME/CFS peaks in adolescence and in early middle-age and that early onset ME/CFS is more common in those with affected relatives, more often triggered by infection, and associated with more severe disease.

1/7 Excited to share our new paper co-produced with @simonmcg.bsky.social. We found that previous reports of ME having two age peaks in Norway replicates in two different datasets and across 7/10 European countries we examined, suggesting this is a generalisable- and distinctive- feature of ME.

Three onset age distributions for ME/CFS, one for Norway, one for the combined 9 other countries, and one for a DecodeME subcohort, with fitted splines.

Calling pwME in the UK- please fill out this survey if you haven't yet! I'll be using data from this survey to better understand at what ages people develop ME and from what types of triggers. Thanks to everyone who has taken part so far!

1) Saw some skepticism about DecodeME, asking if it is overhyped. As an account that focuses on critically analyzing research (our name was 'ME/CFS Skeptic' for a reason!), we think it’s the real deal. Here are a couple of reasons why it stands out. 🧵
