Description

A growing class of illnesses shares a clinical signature that current pharmacovigilance is ill-equipped to detect: a transient exposure - a drug course, an infection, a trauma, a chemical event - initiates a chronic, multisystem phenotype that persists long after the initiating agent is cleared. Post-SSRI sexual dysfunction (PSSD), post-finasteride syndrome (PFS), Long COVID, ME/CFS, PTSD, and Gulf War illness are typically studied in isolation, yet they share persistence after cessation, multisystem heterogeneity, discordance with single-axis biomarkers, and nonlinear course.

This presentation argues that these conditions form a coherent family - Post-Exposure Syndromes (PES) - and that their shared structure is topological rather than molecular.

Using PSSD as the anchor case, we formalize each syndrome as a subset S ⊂ X of a high-dimensional, multi-omic organismic state space.

A PES is a trapped set T: a region forward-invariant under ordinary dynamics, exited only by non-ordinary perturbation. Exposures are modeled as operators Φₑ on state space; because these operators do not generally commute, exposure history and order become formally essential rather than incidental.

Aging is reframed in part as the slow integral of the exposome across the life course, with PES as its acute, focal crystallisations - same operator class, different timescale.

The framework yields falsifiable predictions (discrete state clustering, hysteresis under perturbation, measurable exposure-order effects) and reorients the clinical question from "what single pathway is broken?" to "what keeps this system in this state, and what would restore reachability?"

Four implications follow for pharmacovigilance: reforming adverse-event reporting to include post-discontinuation windows, establishing active surveillance cohorts for persistent syndromes, informed-consent language that names persistence risk, and modeling exposure history rather than point exposures.

I don’t think that has ever been the clinical question for the researchers and clinicians that know what they are doing..

Surely, this has to be a Sokal-style hoax?

Or, are we dealing with voyeurism form formal logic, just to balance the voyeurism from the humanities?

Well, this is making the most fundamental error to start with - to treat a dynamical question as a question about states. The same mistake the fundamental physics people make, and the consciousness science people and no doubt people in all sorts of other disciplines.

Thank goodness for the island of sanity that is S4mE.

Can you explain the basics of what dynamical questions are?

Can you explain the basics of what dynamical questions are?

What happens (and according to what predispositions), rather than what is.

(The underlying point being that existence can only ultimately be known in terms of what happens.)

Thank you!

How would you describe «the state of the lamp above me is that it is off» in terms of happenings?

Is it that the retina was hit by photons that caused nerves to pass signals to neurons that correspond to what they/it recognise as an unlit lamp? The last part about neurons might not be accurate, but you hopefully get the point.

That sort of thing but in simple terms a 'lamp that is off' is the absence of some electron and electromagentic field happenings in a spacetime domain in which other happenings in quark, electron and associated fields have a 'lamp' arrangement.

Here's my critique of this framework (when it was just a PowerPoint presentation) on Reddit:


However, I do think the epigenetic theory of PSSD (primarily developed by Csoka) is the best theory of PSSD. Here's my thread on it on X:

Lol. Is this why high-schoolers hate math: Neither useful nor elegant.

Hey! No bashing fundamental physics on my watch! Those people get enough crap from the while science populist crowd.

Quantum field theory is nothing but dynamic. Particles as waves and interactions as transfer of energy between fields.

Explain yourself!

(Note because this is the internet: The above post is written in an exaggerated way for comedic effect. I'm not actually angry. Mostly curious.)

Quantum field theory is nothing but dynamic. Particles as waves and interactions as transfer of energy between fields.

You have the contradiction right there. The 'particle' concept is not dynamics. All QFT is about is fields which behave as if values in different domains can be accounted for by individuated 'dynamic connections'. The beauty of quantum theory is that it justifies giving these connections no descriptors like 'particle' or 'wave' because such descriptors inevitably imply further dynamic divisibility and it is a great relief to have a theory that says there is no further divisibility. The connections are like chess moves made on a computer - with no 'thing' having any 'trajectory'. You can get rid of 'things'. As Leibniz pointed out, the only 'realities' you need beyond the field connections to make it physics rather than math are conscious experiences. Einstein makes the same point in 1922, even if Einstein often contradicted himself when it came to metaphysics.

The rules of what moves are likely to be made include cyclical math, just as bus timetables do, but it was a great mistake to think that cyclicity described something spinning or waving up and down. If high school kids were taught that rather than 'wave-particle duality' rather fewer of them might be put off physics for life.

The specific issue is that of a 'wave function' being in a 'state' prior to 'collapse. Aspect showed that was not the case (as if anyone needed to).
