Louisa Nicola - Neurophysiologist Warns About the Hidden Dangers of Black-Market Peptides | SRS #300

Only 3-5% of Alzheimer's disease cases are directly driven by specific genetic mutations. The vast majority (95%) are influenced by lifestyle factors, offering individuals significant agency over their brain health. Even carriers of high-risk genes like APOE4 can mitigate their risk through lifestyle interventions.

Louisa states, '95% of all Alzheimer's disease cases were driven through lifestyle' and '3 to 5% of the total Alzheimer's disease patients or cases that possess the risk factor genes.' She references a study in Africa showing high APOE4 carriers but low Alzheimer's rates due to lifestyle.

A foundational 2003 study on amyloid beta 56, which claimed to identify the sole cause of Alzheimer's, was found to be fraudulent in 2022. This scandal led to $300 million per year in NIH funding and billions from pharmaceutical companies being wasted on a non-existent target, delaying genuine progress and eroding trust in science.

Louisa details how Sylvane Lesner's 2003 paper, published in 'Nature,' was cited 2,300 times and received massive funding, only to be found fraudulent in 2022 due to manipulated images. She calls it 'the biggest scandal in the amyloid cascade hypothesis.'

New intravenous drugs like Lecanemab, costing around $26,000 per administration, are designed to clear amyloid plaques from the brain. However, clinical trials revealed that these drugs caused microhemorrhages (brain bleeds) and deaths, and critically, did not preserve patients' cognitive functions or memory, rendering the treatment ineffective for its primary goal.

Louisa explains Lecanemab's cost and mechanism, stating, 'deaths were occurring and something called ARA, which is basically when you administer this drug, it's causing microhemorrhages in the brain.' She adds, 'It wasn't preserving their cognitive functions. So they clearing out the amaloid but they're still not themselves are still not remembering things.'

Amyloid beta is a naturally occurring antimicrobial peptide released by neurons to trap and kill pathogens like viruses or bacteria that enter the brain. Problems arise when chronic stress, inflammation, or infections lead to excessive amyloid ejection and impaired clearance during deep sleep, causing it to accumulate into toxic plaques.

Louisa clarifies, 'amaloid is not the demon.' She explains, 'Your brain is so strong... amaloid actually lives in your neurons and it actually gets ejected out of the neurons in the event of an attack, a microbial attack... It engulfs it and it kills it.'

Women account for nearly two-thirds of Alzheimer's patients. This increased risk is largely attributed to living longer than men and the steep decline of estrogen during menopause. Estrogen is a crucial neuroendocrine hormone that helps shuttle glucose into brain cells and reduces neural inflammation; its loss compromises brain cell energy and increases vulnerability.

Louisa states, 'The second biggest risk factor is being female' and explains it's due to women living longer and the 'hormonal transition which is causing the increased risk factors of getting this disease.' She details estrogen's role as a neuroendocrine hormone vital for brain cell survival, glucose shuttling, and neural inflammation reduction.

Peptides like BPC-157, often used for recovery, induce vascularization (new blood vessel formation). While beneficial for injury healing, this process cannot differentiate between healthy tissue and undetected cancer cells. Since most early-stage cancers are asymptomatic and undetectable, using these peptides risks accelerating tumor growth by feeding them a new blood supply.

Louisa warns, 'BPC57... is doing this by inducing vascularization... But it can't detect whether it's causing vascularization on a cancer cell.' She emphasizes, 'We could all be walking around right now with it. It's just too small to detect on neuroimaging.'

Large-scale studies in Wales, Australia, and the US have shown that receiving the shingles vaccine after age 50 can lower the risk of all-cause dementia and Alzheimer's disease by 50%. This is because the shingles virus (reactivated chickenpox) can travel to the brain, triggering amyloid release and neural inflammation, which the vaccine prevents.

Louisa cites 'the largest studies ever done... for the shingles vaccine has showed that if you receive the shingles vaccine after the age of 50, you lower your risk of all cause dementia and Alzheimer's disease by 50%.' She explains the mechanism: 'It goes up into the brain and... releases all this amaloid beta to try and engulf it.'

Taking 10-12 grams of creatine daily can effectively raise brain creatine levels, improving energy production in brain cells (mitochondria). This enhanced energy metabolism is crucial for fighting neurodegenerative diseases like Alzheimer's (which involve an 'energy crisis') and can alleviate symptoms of depression and sleep deprivation. A pilot study showed 20g daily improved global cognition in Alzheimer's patients.

Louisa explains, 'taking 10 g to 12 g a day can effectively raise your brain creatine levels.' She notes it 'helps the brain cells produce energy better' and references a pilot study where '20 groups of Alzheimer's patients... Took 20 grams of creatine per day for 8 weeks... they increased their global cognition scores.'
