  • SequenceME DNA sequencing study gets £4.7m

    Follow-up project to DecodeME will analysye complete Genome sequences of 9000 ME/CFS existing samples to help pinpoint biology of ME and hopefully lead to treatments. Loads of detail in this article by Simon McGrath about how the DNA will be sequenced etc. using Oxford Nanopore technology.

    It is ME Awareness Day and I’ve had a tough one, so I’ll write a bit more soon… But didn’t want to forget documenting here what seems a major step in the right direction.

  • Hidden Illness, Public Grief, and Research Funding: Why ME/CFS and Other Gradual-Onset Conditions Struggle for Recognition

    Author: Steve Fifield 3rd March 2026

    I wrote a simple draft paper on possible reasons why ME/CFS and similar conditions struggle so much for public recognition and funding.

    Executive Summary

    This briefing paper proposes that illnesses characterised by gradual onset, symptom invisibility, and ambiguous loss—such as Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS)—face structural disadvantages in public recognition and research funding.

    In contrast to diseases associated with sudden, catastrophic diagnoses (e.g., cancer, motor neurone disease, multiple sclerosis), ME/CFS often progresses gradually, without a singular crisis moment that mobilises families, media, and policymakers.

    Drawing on psychological research, communication theory, medical sociology, and health policy analysis, this paper outlines evidence supporting the hypothesis that acute grief catalyses mobilisation, while chronic ambiguity fosters adaptation rather than advocacy.

    1. Proposition Statement

    Public support for disease research funding is strongly influenced by emotional salience, narrative clarity, and visibility.

    • This paper proposes that:
    • Sudden, high-intensity diagnoses generate collective grief and advocacy mobilisation.
    • Gradual, invisible illness trajectories tend to produce adaptation and normalisation rather than public outrage.
    • Conditions lacking clear biomarkers or dramatic ‘trigger events’ may remain socially marginalised and underfunded.

    2. Psychological Evidence: Emotion, Grief, and Giving

    Research in behavioural psychology demonstrates that emotional intensity significantly influences charitable giving and advocacy behaviour.

    • Key evidence includes:
    • The ‘Identifiable Victim Effect’ shows individuals donate more readily when harm is concrete and personal (Small & Loewenstein, 2003).
    • Personal experience with illness strongly predicts sustained advocacy engagement (Bekkers & Wiepking, 2011).
    • Acute grief produces action-oriented coping responses, whereas ambiguous loss can lead to prolonged emotional adjustment rather than mobilisation (Boss, 1999).

    3. Media Visibility and Agenda Setting

    Agenda-setting research demonstrates that media coverage shapes public perceptions of issue importance (McCombs & Shaw, 1972).

    • Relevant dynamics:
    • Diseases with dramatic diagnostic narratives are more likely to receive concentrated media attention.
    • High-visibility campaigns (e.g., viral fundraising movements) significantly increase funding inflows.
    • Invisible or contested illnesses struggle to achieve sustained media framing as urgent biomedical crises.

    4. Medical Sociology: Invisible and Contested Illness

    ME/CFS has historically been classified as a contested or medically unexplained illness.

    • Sociological findings show:
    • Illnesses lacking objective biomarkers often face legitimacy challenges (Barker, 2008).
    • Symptom invisibility contributes to stigma and disbelief (Dickson et al., 2007).
    • Gradual functional decline may be socially normalised within families, reducing collective mobilisation.

    5. Research Funding and Disease Burden

    Multiple analyses indicate that biomedical research funding does not consistently align with disease burden.

    • Findings relevant to ME/CFS:
    • Funding levels for ME/CFS have historically been substantially lower than expected based on disability-adjusted life years (DALYs) (Dimmock et al., 2016).
    • Mortality salience and media visibility correlate more strongly with funding allocation than chronic disability alone.
    • Conditions perceived as life-threatening often secure greater political and philanthropic urgency.

    6. Policy and Strategic Implications

    If this proposition is valid, important implications follow for research institutions, advocacy organisations, and policymakers.

    • Potential strategies:
    • Develop narrative frameworks that communicate cumulative functional loss without sensationalism.
    • Align funding mechanisms more closely with disease burden metrics rather than media salience.
    • Invest in biomarker research to strengthen clinical legitimacy.
    • Promote public education campaigns that clarify the biological basis and severity of ME/CFS.

    Conclusion

    ME/CFS exemplifies how gradual-onset, invisible illnesses may be structurally disadvantaged within public funding ecosystems shaped by emotion, visibility, and narrative shock.

    Addressing this imbalance requires deliberate policy design, improved public communication, and recognition that chronic disability without dramatic rupture can be equally life-altering.

    New Abstract on invasive CPET – Promising outcomes

    The American Journal of Respiratory and Critical Care Medicine has posted a new abstract authored by David Systrom et al, which evaluated invasive CPET testing. The test includes iCPET results from 438 ME/CFS patients, 73 Long Covid patients, and 43 symptomatic but otherwise normal controls.

    The measurement method is illustrated here from their previous 2023 report [TBA]

    The full Abstract within the American Journal of Respiratory and Critical Care Medicine can be found here: https://www.atsjournals.org/doi/abs/10.1164/ajrccm.2025.211.Abstracts.A7881

    An image extract from the article is shown below, showing correlation of pVO2 between each cohort and outcomes, and remarkably similar results from ME and Long Covid:

    The Latest Research on Mitochondrial Dysfunction in Long Covid & ME/CFS | With Prof. Klaus Wirth

    Gez Medinger talks with Prof. Klaus Wirth about his research into Mitochondrial Dysfunction, particularly in relation to intramuscular sodium levels. He reassures us that intramuscular sodium levels are not influenced by additional salt intake typically used to increase blood volume, for those suffering from orthostatic intolerance or POTS.

    Part 2 looks at use of a potential new drug, referred to as MDC002:

  • Norwegian study shows – ME patients rarely return to work

    What can wage development before and after a G93.3 diagnosis tell us about prognoses for myalgic encephalomyelitis?

    A Norwegian study has shown that patients diagnosed with ME typically decline permanently in terms of their earning capabilities, as illustrated below by the drop in their average wage income over a period starting 9 years before diagnosis in 2016, until 9 years later in 2025. Less than 6% maintained an income of at least median wages after diagnosis.

    Nine years before diagnosis, the men earned slightly less than their controls. Wages in the men’s groups then started falling sharply towards Y0 and continued falling in the first year after (Y1). They then fell more gradually towards Y9. The women’s average wages 9 years before diagnosis were slightly below their female controls. The wages fell more sharply between 2 years before and 1 year after diagnosis, where they stabilized at a low level.

    Fig. 3. Comparing group average wages for men and women 18–67 years old, diagnosed with G93.3, from 9 years before until 9 years after diagnosis (N = 6249) using 2009–2018 data to simulate values for the control group (N = 2739).

  • Health-related quality of life in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome and Post COVID-19 Condition: a systematic review

    A Meta Study, Comparing ME/CFS and Long Covid symptoms and quality of life. From the conclusions section:

     Shared impact patterns were observed between the two illness cohorts. Profound impairments were consistently observed in self-perceptions of overall health status, physical health domains and ability to perform daily activities. Although only provided in one study, there were no significant differences in direct comparisons of HRQoL outcomes between pwME/CFS and pwPCC.

    Extract – Abstract

    Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a chronic neurologic disease
    often preceded by infection. There has been increased interest in ME/CFS recently
    because of its significant overlap with the post-COVID syndrome (long COVID or post-acute
    sequelae of COVID), with several studies estimating that half of patients with post-COVID
    syndrome fulfill ME/CFS criteria. Our concise review describes a generalist approach to
    ME/CFS, including diagnosis, evaluation, and management strategies.

  • Post Vaccination Syndrome (PVS) preprint published by Yale University

    A preprint study from Yale University appears to identify individuals suffering from PVS with elevated levels of circulating isolated spike protein, compared to healthy controls, implying that the source is from a vaccine. Those studied had no prior history or evidence of a SARS-Cov2 infection.

    Researchers have since publication pointed out that Long Covid existed significantly before vaccines were available, defending suggestions from some that Long Covid had somehow been caused purely as a result of vaccination. This is not the case, and PVS forms a very small subset of those suffering with Long Covid Symptoms.

  • Large hippocampus detected in Long COVID and ME/CFS patients

    This study compared alterations in hippocampal subfields of 17 long COVID, 29 ME/CFS patients, and 15 healthy controls (HC), identifying significantly larger volumes in the left hippocampal subfields of both long COVID and ME/CFS patients compared to Healthy Controls.

    Abstract

    Long COVID and Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) patients share similar symptoms including post-exertional malaise, neurocognitive impairment, and memory loss. The neurocognitive impairment in both conditions might be linked to alterations in the hippocampal subfields. Therefore, this study compared alterations in hippocampal subfields of 17 long COVID, 29 ME/CFS patients, and 15 healthy controls (HC).
