    The role of illness perception and behaviour in the treatment of adolescents with multisystem functional somatic disorders:... 2025 Kallesøe et al

    More authors who don't understand that scale responses are not symptoms themselves. They never seem to acknowledge the role of altered cognitions during interventions in inducing increased response biases on scales.

    What could it mean biologically that both physical and cognitive exertion can cause PEM?

    I wonder about this too, usually cognitive activity can have additional physical/orthostatic demands at the same time so there sort of needs to be a control (doing the same activity but without the cognitive demand). But I think there is something there with regards to autonomic symptoms, those...

    The association between Autism Spectrum Disorder and Chronic Fatigue Syndrome. A Care Plan Perspective, 2025, Nida Khubaib

    I don't think there is any direct overlap in terms of pathology (and all the cited evidence in the study is very weak and speculative - generalised claims about neuroinflammation are meaningless), but of course there are always going to be patients whom the conditions co-occur (and they are more...

    What could it mean biologically that both physical and cognitive exertion can cause PEM?

    There is a phenomena known as sympathetic sprouting, post neurological injury, there is coupling of afferent (sensory) nerves with downstream efferent sympathetic nerves. This helps aid neurological recovery but can also lead to altered sensitisation of those nerves. Obviously this requires...

    What could it mean biologically that both physical and cognitive exertion can cause PEM?

    Not in ME/CFS but it doesn't do that much in healthy people - it doesn't actually improve exercise performance. Studies of catecolamine levels in circulation in adults with ME/CFS largely show nothing abnormal. The only exercise study I know of was immediately after (lower adrenaline) and no...

    What could it mean biologically that both physical and cognitive exertion can cause PEM?

    My hypothesis to explain this is dysfunction of the autonomic nervous system too, but I don't think it is any sort of generalised "activation of the sympathetic nervous system at all". I think it is more subtle and to do with specific types of nerves rather than the whole system.

    Trial Report Awe reduces depressive symptoms and improves well-being in a randomized-controlled clinical trial, 2025, Lopez et al

    This is Scientific Reports, not Nature proper and yes, peer review quality is mixed across and even within journals.

    Push to change ‘misogynistic’ name of one of the world’s most common surgeries

    Agreed. I don't see why there is push-back against changing the name.

    Similar to a few noteworthy people from the UK? ;)

    ME/CFS Research Chatbot

    It wasn't terrible in terms of misinformation, it just gives no answer or vague answers, but I didn't find it useful either. The problem is largely garbage in therefore garbage out. These LLMs are great at rearranging words but poor at specific reasoning.

    PIP cuts won't fix ‘alarming' benefit fraud, experts warn Labour

    Ugh, real fraud numbers are no where near that high.

    Reddit - Interesting posts on Reddit, including what some doctors say about ME/CFS

    Australian Doctors are among the highest paid of all, so of course the Australian doctors are constantly whining on Reddit about how their pay rises aren't well above the rate of inflation (unlike most households who's incomes are going backwards against inflation) and they seem to brigade any...

    How did Fibromyalgia become a brain disease? Disentangling conjecture and truth.

    The issue might not necessarily be central sensitivity across varying patients, but the key is to probe the system as much as possible rather than continue to propose putative conjecture and never test it.

    How did Fibromyalgia become a brain disease? Disentangling conjecture and truth.

    We're talking about targeted scientific studies on nerve function rather than as a treatment effect though.

    Neural mechanisms underlying the effects of physical fatigue on effort-based choice (2020) Hogan et al

    The Science daily article is a bit confused. The results are largely unsuprising. They simply associated lower activity of some premotor regions with less compensatory effort during fatiguing activity. The sense of effort is upstream of the motor cortex and is effectively the level of...
