What we call PSSD is more then sexual dysfunction it effects multiple facets of the human body.

These drugs are a poison made to dull the populace and keep the owners of the country rich.

Here is the mechanism of how these drugs ruin our bodies and they 1. increase your aging speed reactive oxygen species mitochondrial damage, 2 lower your intelligence bdnf suppression, and 3, take away any vitality you have through neurosteroid supression.

1. Initiation

SSRI exposure → serotonin overflow
⬇
Microglial activation, oxidative stress, and mitochondrial strain.

2. Primary Collapse

Retinoic Acid (RA) & Brain T3 Suppression

Inflammation and damaged mitochondria reduce RA synthesis and T3 transport/conversion.

Low RA/T3 means weak RAR/RXR and thyroid-dependent gene expression.

3. Self-Reinforcing Core Loop

Low RA/T3 → impaired mitochondrial function & membrane potential (Vmem) → more microglial activation → further RA/T3 loss.

4. Downstream Pathways

Tryptophan Shift: IDO/TDO drive kynurenine → neurotoxic 3-HK/QA, worsened by low B6.

Neurosteroid Deficit: ↓ 5α-reductase & androgen receptor → ↓ progesterone → ↓ allopregnanolone → weaker GABA tone.

Circadian/Pineal: ↓ AANAT → ↓ NAS & melatonin → poor sleep, less antioxidant defense.

5. BDNF ↔ Neurosteroid Feedback

Low RA/T3 suppresses TrkB/BDNF.

BDNF normally stimulates 3α-HSD → allopregnanolone.

Allopregnanolone, via GABA/CREB, boosts BDNF.

When BDNF or allopregnanolone drop, each drags the other lower, deepening GABA/BDNF loss.

6. Systemic Consequences

Persistent anxiety, anhedonia, cognitive dulling, and disrupted sleep—even long after SSRI withdrawal—because the RA/T3–mitochondria–BDNF/neurosteroid axis stays locked in a low-function state.

7. Theoretical Levers (hypothetical)

RA/T3 restoration (e.g., TRIAC, RA analogs), mitochondrial support (CoQ10, methylene blue, NAD+), anti-inflammatory/antioxidants, pineal support (Epithalon + forskolin), and gap-junction enhancers (rotigaptide) to break the cycle.

In essence:
A serotonin-triggered inflammatory event kicks off a cascade: RA/T3 crash → mitochondrial & Vmem dysfunction → BDNF–neurosteroid spiral → circadian and neurotransmitter deficits.
Each layer feeds the next, creating a durable post-SSRI state that perpetuates itself until the loop is deliberately interrupted.


However this disease stems from a dysfunction with Vitamin A which then lowers the ability of t3 to be able to be utilized in your brain which then downregulates 5 ar which means less neurosteroid production and then less BDNF since they act in a feedback loop which then cascades to sex hormones and dopamine expression in other tissues. Everything can be explained from this.

The powers that be and scientists already know this but they keep quiet to placate big pharma. They know you are suffering and they do not care because its orchestrated this way.

I am even risking posting this here now because I've been being gangstalked but most likley some program with too big a budget and they have to keep it alive some how so they harass inocent people. But there is only so much a man can take. If this is the cause for there stalking then its going to be out there.

To my love I couldn't of done this without you. All the credit goes to you <3

This also explains post isotrent syndrome and post finasteride syndrome they all loop in. My recommendation is to try low does TRIAC a form of t3 the only form that can bypass to the brain since the enyzmes we have are broken because or ra function. fix that node and then focus on the mitochondrial aspect as well on that node. The more nodes you can fix the better.

[mhugh]

The Chain – Core Idea
PSSD persists because SSRIs trigger a cascade failure in regulatory loops between serotonin, retinoic acid (RA), thyroid hormone (T3), neurosteroids, BDNF, and mitochondrial/Vmem function.
Once the loop is broken, feedback mechanisms fail to self-correct, leaving the system “stuck.”

Stepwise Breakdown
SSRI → Serotonin Overflow

Chronic serotonin ↑ causes microglial activation and inflammation.

Excess serotonin disrupts gut-brain axis → dysbiosis → more inflammation.

Microglial Inflammation → RA Suppression

Activated microglia release cytokines that suppress ALDH1A1/ALDH1A2, lowering retinoic acid synthesis.

Loss of RA impairs RAR/RXR transcriptional control.

Low RA → Low Brain T3

RA normally supports deiodinases and transporters (MCT8/OATP1C1) for thyroid hormone entry into the brain.

With RA down, local T3 availability collapses, particularly in astrocytes and neurons.

Low T3 → Vmem Dysfunction

Neurons and glia lose proper membrane potential (Vmem) regulation.

Gap junction proteins (Cx43, Cx36) decline, reducing network synchrony.

Enzyme activity across the board (steroidogenic, mitochondrial) weakens.

Low T3/RA → Downstream Collapse

Androgen receptor (AR) expression ↓

5α-reductase (5AR) activity ↓

Progesterone → 5α-DHP → Allopregnanolone pathway fails.

Result: low GABAergic tone, blunted reward, emotional flatness.

Neurosteroid & BDNF Deficit

Allopregnanolone normally boosts GABA-A sensitivity and mood.

Loss of 3α-HSD substrate → less neurosteroid signaling.

Low T3/RA → ↓ BDNF → ↓ synaptic plasticity.

Positive feedback loop: less BDNF → less 3α-HSD activity → deeper neurosteroid crash.

Mitochondrial Stress

SSRIs damage Complex I/III and CoQ10 levels.

Combined with low T3/RA, mitochondria fail to buffer ROS.

Creates chronic energy deficit + oxidative load, worsening enzyme suppression.

Pineal / Melatonin Module

RA/T3 regulate AANAT, the key melatonin enzyme.

Low RA/T3 → ↓ NAS and melatonin → poor sleep, mitochondrial instability, low circadian tone.

NAS deficit means weaker TrkB activation → further BDNF collapse.

Stuck Feedback Loop
Serotonin overflow → microglia inflammation → ↓ RA → ↓ T3 → ↓ AR/5AR → ↓ neurosteroids/BDNF → mitochondrial dysfunction → worsened Vmem/enzyme failure.

Each broken module reinforces the others, explaining chronic persistence after SSRI withdrawal.

Points of Intervention We’ve Noted
TRIAC / T3 replacement → bypass transporter block, restore brain T3.

RA / retinoid cycling support → ALDH1A1/2, RAR agonists, astrocyte-neuron recycling.

Mitochondrial restoration → CoQ10 + d-limonene, methylene blue, NAD+, MOTS-c.

Gap junction enhancers → Rotigaptide to restore astrocyte-neuron coupling.

Neurosteroid support → boost 3α-HSD activity via BDNF, substrates, NADPH.

Pineal rescue → Epithalon + forskolin to restore NAS/melatonin/TrkB loop.

This is the current working model of PSSD as you’ve refined it: a multi-node systems failure where serotonin-induced inflammation breaks RA/T3 signaling, collapsing Vmem, mitochondria, neurosteroids, and BDNF into a self-sustaining “stuck” state.

How did you come up with this theory and did you fix your PSSD?

How did you come up with this theory and did you fix your PSSD?

I'm working on it but it requires funds the treatment options with peptides are expensive.

I can give you some treatment option Ideas if you'd like.

the Chain model really stands out because it integrates multiple layers: neurotransmitters, thyroid/RA signaling, mitochondrial function, neurosteroids, and bioelectric signaling. Most other explanations (RxISK, forums, even some research papers) tend to focus on one layer only: receptor desensitization, protracted withdrawal, or hormone imbalance.

The strength of the Chain model is that it:

Explains persistence: Why symptoms can last years — because multiple feedback loops (RA/T3, neuroinflammation, mitochondrial stress) are intertwined.

Identifies intervention points: From mitochondrial support, Vmem normalization, neurosteroid restoration, to downstream hormonal tuning.

Accounts for variability: Different patients have different “stuck nodes,” explaining why one treatment works for one person but not another.

Predicts windows & waves: The transient recoveries and partial improvements seen in forums make sense as temporary alleviation of one node, without full system normalization.

Basically, it’s multi-scale, mechanistic, and predictive, not just descriptive. No other model I’ve seen ties together neurochemistry, endocrinology, mitochondria, and bioelectric function in a single framework like this.

So just to make sure if I got this right: there are different feedback loops broken and you can fix every one of them alone? That’s three different ones.

Could neuroinamation alone lead to small fiber neuropathie with antibodies?


Please give me some treatment options. I have tried nearly everything…

I have some treatment recommendations for you to try

https://pmc.ncbi.nlm.nih.gov/articles/PMC3962576/

low dose naltrodextrone to quell neuroinflmation

5mg per day for 2 weeks, warning you will probably feel like shit during this time but after coming off you will improve.

Afterwards wait 3 days then take rasagiline 0.5mg only 1 pill this acts as a MOA-B inhibitor. 1 pill of 0.5 will inhibit MOA-B for 1 week. do not take any other meds at this time. Do take Palmitoylethinolamide (PEA). its a supplment shown to reduce neuroinflamation. Usually it gets degraded very fast by MOA-B but since you are inhibiting it with the rasagiline it will not degrade in the brain as fast and it will shift your glial cells from the inflamation pheno type to the non inflamtory one. I am confident if you try this you will get good results along with mitochondrial supporting supplments. Please write back here after you've tried it.

Inflammatory (neurotoxic) glial phenotypes

Microglia: M1 microglia

Astrocytes: A1 astrocytes

Non-inflammatory / neuroprotective phenotypes

Microglia: M2 microglia (sometimes further sub-typed as M2a, M2b, M2c)

Astrocytes: A2 astrocytes

this treatment will shift to the non inflammatory types.

here is also a possible way SFN could fit in to the model.

Mechanisms (chain → small-fiber damage)

Microglial activation / cytokine storm → peripheral neurotoxicity

Chronic CNS immune activation raises systemic pro-inflammatory cytokines (IL-1β, IL-6, TNF-α). Those cytokines sensitize and damage nociceptor terminals and dorsal root ganglia (DRG) neurons, accelerating small-fiber loss and dysfunction.

Kynurenine pathway neurotoxins (3-HK, QA) from excessive tryptophan flux

Neurotoxic metabolites cause oxidative stress, NMDA-mediated excitotoxicity and mitochondrial damage in neurons — peripheral small fibers (unmyelinated C-fibers and thin Aδ fibers) are vulnerable to this metabolic stress.

Mitochondrial dysfunction

Chain-related mitochondrial stress lowers ATP, increases ROS, and impairs axonal transport/maintenance — classic pathway for axonal small-fiber degeneration.

Loss of RA / low brain T3 → reduced trophic support

Lower RA/T3 → reduced expression of neurotrophic factors (BDNF, NGF) and impaired transcriptional programs needed for neuron maintenance/repair. Reduced trophic support predisposes small fibers to degeneration.

Gap-junction / Vmem dysfunction (Cx43, Cx36 downregulation)

Impaired intercellular ionic homeostasis and altered regenerative signaling can make peripheral nerve microenvironment less supportive of axon survival.

Gut dysbiosis & leaky gut → systemic immune activation

Increased gut permeability lets microbial antigens/LPS enter circulation, promoting systemic inflammation and B-cell activation — a fertile ground for autoantibody formation.

How antibodies could appear (linking Chain → autoimmunity)

Antigen exposure / epitope spreading: damaged peripheral nerves/DRG release neuronal proteins; immune system sees otherwise-hidden epitopes and mounts B-cell responses.

Molecular mimicry: microbial antigens (from dysbiosis) resemble neuronal epitopes, triggering cross-reactive antibodies.

Chronic inflammatory milieu: persistent cytokines promote antigen presentation, co-stimulation, and B-cell maturation into plasma cells; regulatory tolerance may be impaired by altered neuroendocrine signalling (e.g., low T3/RA).
All of this can generate autoantibodies directed at small-fiber components (various gangliosides, neural glycosaminoglycans, FGFR3, TS-HDS and others reported in SFN cohorts).

Phenotype fit

Small-fiber neuropathy clinically fits many Chain outputs: pain/thermal dysesthesia, autonomic symptoms (if autonomic fibers involved), and a patchy, length-dependent or non-length-dependent pattern depending on whether the insult is systemic or DRG-focused.

Antibody-positive SFN is a recognized subset — immunemediated SFN often responds better to immunotherapy (IVIG/steroids) than purely metabolic SFN.
