Approximately 45% to 50% of women who receive general anesthesia for a C-section develop postpartum depression, compared to roughly 28% to 30% with an epidural and 10% to 12% with unmedicated birth.
"it's something like 45% of patients who have to have general anesthesia will have post for C-section will have a postpartum depression, versus oh versus like 10 or 20, 10 to 12%. And I got to look the study up too, so this the statistics may not be perfect, but it's a large up it's a... Closer to 50% when you're having a C-section in her general versus epidural versus awake. And there's even a stat, so epidural even impact, yeah, there's an impact, so it's something like 30% or 28% with an epidural and then 12% without anything" (said at 0:17:20)
The speaker correctly identifies that general anesthesia for cesarean delivery is associated with a higher risk of postpartum depression (PPD) compared to neuraxial anesthesia (epidural/spinal) or unmedicated birth, but the claimed absolute rates (45–50% for general anesthesia, 28–30% for epidurals, and 10–12% for unmedicated birth) significantly inflate clinical PPD incidence.
A systematic review and meta-analysis of over 1.4 million women found that general anesthesia during cesarean delivery significantly increases the risk of PPD compared to non-general anesthesia (odds ratio 1.64). However, population-based cohort studies evaluating clinically diagnosed PPD show 1-year incidence rates of roughly 1.1% for general anesthesia versus 0.86% for neuraxial anesthesia. The source of figures near 44% is a single Taiwanese database study that used a broad composite definition of 'postpartum depressive disorders' including sleep disorders and hypnotic/sedative prescriptions (finding composite rates of 43.87% for general anesthesia, 36.30% for neuraxial anesthesia, and 26.66% for natural births). Standard clinical PPD diagnosis rates do not reach 45–50%.

Well-muscled young men under age 30 frequently experience emergence delirium upon waking up from anesthesia.
"young men I would say under the age of 30, well muscled, they wake up very delirious." (said at 0:54:50)
While some observational literature identifies younger adult age (such as under 40 years) as an independent risk factor for emergence agitation/delirium compared to middle-aged adults, emergence delirium is not uniquely frequent to well-muscled young men. Across adult surgical populations, emergence agitation occurs in approximately 5% to 19% of patients and is predominantly associated with invasive devices (e.g., endotracheal tubes, urinary catheters), inadequate pain control, surgical location (particularly otolaryngology), volatile anesthetic maintenance, and underlying substance use or psychiatric conditions (such as PTSD). Furthermore, clinical reviews note that emergence delirium is most prevalent at the extremes of age (pediatric and elderly populations).

"Significant risk factors for emergence delirium were premedication with benzodiazepines, induction of anesthesia with etomidate, younger as well as older age (age below 40 years and over 64 years), higher postoperative pain scores (NRS 6-10) and musculoskeletal surgery."

Recent research demonstrates that dementia can be reversed.
"There's all this new study that said we can reverse dementia, but how about we prevent it?" (said at 1:10:45)
The claim that recent research demonstrates dementia can be reversed overstates the current clinical evidence. While small case series and non-randomized pilot studies investigating personalized, multimodal lifestyle and metabolic protocols (such as MEND/ReCODE) have reported cognitive improvements in small groups of patients with subjective cognitive impairment, mild cognitive impairment, or early-stage Alzheimer's disease (PMID: 27294343), established dementia remains clinically irreversible. The available evidence supporting cognitive 'reversal' relies primarily on observational findings, small unblinded cohorts, and case reports rather than large, double-blind randomized controlled trials (PMID: 36675177, PMID: 42451206). Systematic reviews emphasize that definitive treatments capable of producing long-term cognitive reversal of established Alzheimer's disease or other dementias have not been demonstrated in high-quality clinical trials.
