Delighted our (@jonroiser @ProfRobHoward @a_schrag @ymyymmr @karelkieslich) paper is now out in @Brain1878! 🎉 We show that #Parkinson's #depression may stem from a reduction in reward sensitivity that is unresponsive to dopaminergic medication: 🔗 doi.org/10.1093/brain/awaf09… 🧵⬇️

Impaired reward sensitivity in Parkinson's depression is unresponsive to dopamine treatment

Depression in Parkinson’s disease is common and disabling and often includes motivational symptoms such as apathy and anhedonia. Costello et al. show that

the @ASA_UK complaint I made was upheld about Do Health @drchatterjeeuk. Commercial screening brings false positives, false reassurance, overdiagnosis. Will the @gmcuk act on the dozens of drs making false claims and have commercial conflicts of interests?

1/ We discovered something totally unexpected about the neural structure of consciousness that overturns decades of thinking on its biological basis and brings us significantly closer to the recipe for generating conscious awareness.

Rapid alternation of conscious and suppressed stimulus representations in the primate brain

The neural correlates of consciousness remain elusive[1][1]. Previous studies found that high-level visual cortex is weakly modulated by conscious perception[2][2],[3][3], yet a pure signal of...

If I am reading this correctly, Tristan Buckmaster is alleging OAI has a resolution of Navier-Stokes(via Córdoba and Martínez-Zoroa’s program) which maybe used info from Buckmaster and Levent Alpöge’s private Codex sessions What the fuck is happening!!!

But…it was the opposite, I developed a low-cost Covid vaccine technology that actually bypassed big pharma. We did this at $2-4 per dose, reached 100 million people, saved an estimated 300,000-500,000 lives. I made nothing. It’s incredible to watch people cede all their critical thinking skills to conspiracy sites. This is how totalitarian and communist regimes thrive

A long thread on a quasi experimental study modelled on the @Nature paper using Welsh data and suggesting live shingles vaccine protects against dementia. Sadly in 20 times the sample size using precisely the same quasi experimental design we showed no such apparent protection
Gus Hamilton@gushamiltonJul 22
Does the (live) shingles vaccine protect against dementia? We provide important evidence in a new preprint using hospital data from the whole of England in a regression discontinuity design where we *don't* show strong evidence of a causal effect +

Comorbidities and Complications in Parkinson’s Disease in Primary Care

Many comorbidities are increased in PD. However, they are not associated with greater mortality than in controls, and are not sufficient to explain the increased mortality in PD.

I’m not a BMA member, but this statement is one I support: Reducing funding for clinical academics when numbers are already in decline fails to recognise their contribution to the health & wealth of the UK. The financial saving is minimal but I fear the costs will be substantial

RETRACTED! TL;DR: This study, which claimed the time of day had massive effects on immunotherapy efficacy, but which appeared fraudulent, now seems to certainly have been fraudulent. Many thanks to the editors at Nature for handling this quickly and correctly.

@cremieuxrecueilMay 7
A lot of the key details of this study point towards the result not being real. I think we ought to regard it as fraudulent until proven real🧵 To start, the result is as strong as the observational results from the earlier literature. That's very unusual for a trial!
