Childhood stress causes muscle dysfunction in adulthood by damaging oxidative metabolism
-
Yet another study demonstrating that many mysterious, and sometimes severe/fatal (e.g. ALS) muscle-related conditions may be not only bioenergetic in origin, but can trace their causes back to stressful childhood. The study below not only suggests that childhood stress can cause muscle dysfunction in adulthood by inhibiting oxidative phosphorylation (OXPHOS) and ATP synthesis, but that the effects was “dose-dependent”. Namely, each adverse even during childhood had an additional negative effect on ATP synthesis in adulthood, and thus muscle dysfunction severity. While the study does not speculate on mechanisms of action, my guess is that the lower OXPHOS/ATP was driven by reduced thyroid function due to activation of the HPA axis due to the stressful event(s). Of course, HPA activation results in chronically elevated cortisol, and even mainstream medicine admits the latter has devastating effects on the musculoskeletal system. As such, muscle dysfunction in adulthood should be amenable to simple treatments with thyroid or anti-cortisol substances. If those are not accessible, something as simple as aspirin may be able to do the trick since aspirin is not only a metabolic booster, but its metabolite salicylic acid inhibits the enzyme 11b-HSD1, which is the rate-limiting step in cortisol synthesis. Pregnenolone, progesterone, DHEA and various quinones should also be therapeutic. Speaking of quinones, there have been a number of clinical trials with CoQ10 for muscle conditions, but the results have been inconsistent. Aside from the often-insufficient dosages, one of the reasons for the inconsistent results may be that benzoquinones such as CoQ10 are MAO-A inhibitors and that mechanism has a known anti-metabolic effects by decreasing the degradation of serotonin. Using naphthoquinone (e.g. vitamin K) or anthraquinone (e.g. emodin) derivatives may be a better approach as the former are selective inhibitors of MAO-B (which has already been demonstrated to have therapeutic effects in muscle conditions) while the latter are more or less neutral when it comes to neurotransmitters, but happen to inhibit 11b-HSD1 (e.g. emodin), just like salicylic acid. So, something as simple as aspirin + vitamin K may be sufficient to restore proper muscle function.

“…Forty-five percent of the sample reported experiencing one or more adverse childhood events. After adjustment, each additional event was associated with −0.08 SD (95% confidence interval = −0.13, −0.02) lower ATPmax. No association was observed with Max OXPHOS. Adverse childhood events are associated with lower ATP production in later life.”
“…The study examined the function of skeletal muscle of older adults paired with surveys of adverse events they had experienced in childhood. It found that people who experienced greater childhood adversity, reporting one or more adverse events, had poorer muscle metabolism later in life.”
“…The researchers examined muscle biopsies to determine two key features of muscular function: the production of adenosine triphosphate, or ATP, and another measure called oxidative phosphorylation, a process that helps produce ATP. Produced by organelles within cells called mitochondria, ATP provides the chemical energy to fuel cellular function. The researchers also used data from questionnaires that included a set of questions such as: Did a close family member use drugs or alcohol in a way that caused you to worry? Did an adult or parent in your household insult you or put you down? Were you physically abused by a parent or adult in your household? Did you feel loved, important, or special in your family? Were either of your parents absent for a portion of your life? Duchowny found that about 45% of the sample reported experiencing one or more adverse childhood events, and that both men and women who reported adverse childhood events had poorer ATP max production—that is, they weren’t producing as much ATP as people who experienced fewer or no adverse events in childhood.”
“…“You can think about oxygen consumption rate as a way to measure the flow of electrons that’s going through the electron transport train, and it’s these electrons that generate the membrane potential that drives the synthesis of ATP,” Molina says. “It’s a really precise way of assessing mitochondrial bioenergetic capacity.” Previous studies have shown that these measures are closely related to the physical abilities of older adults, Molina says.”
“…“All of my previous studies have been focused on contemporaneous measures: mitochondria and physical function, mitochondria and cognitive function,” Molina says. “These studies have shown that these measures are strongly related to our strength, fitness, and numerous conditions that impact physical ability. “I’ve also shown that these measures are related to cognitive ability and dementia. “

@haidut Fantastic study, commentary and suggestions.
I would love to send this to my sister-in-law whose son seems to have muscular dystrophy. (But I'm not a Doctor. duh-oh!!)
Anyway, thanks for posting it.

Thank you for posting. I would like to see a study that compares vaccinated and unvaccinated children’s response to stress. Many childhood vaccines are linked to muscular skeletal adverse effects. I posted this on another thread recently

@haidut Thank you! Very interesting and helpful post!
BTW This study explains why Aspirin/emodin + K2 made wonders for me when I started peating... Worked almost like a pill from the Limitless movie... LOL!
My life was full of cortisol before that... and no doctor was able to explain this to me...
BTW Interesting to know that CoQ10 is an MAO-A inhibitor!

@Kvirion Can you share the source and what dosages you used?
-
@Energia I use Cascara Sagrada from NOW Foods - 1/3 of a capsule - usually a few times per week (2-3 times, sometimes less - I listen to my body i.e. Perceive-Think-Act.).
Aspirin and K2 - different brands from my local drugstore, usually Aspirin 250 mg once or twice per week and K2 daily.

MK-4 or MK-7?

A mix of both.
