Omega-3 paused Alzheimer's decline - RCT Sept 2021

---

Comments on the study by Dr. Rhonda Patrick

"The intervention study involved 33 people who had been diagnosed with Alzheimer’s disease. Approximately half of the participants took a supplement providing 2.3 grams of omega-3 fatty acids daily for six months; the other half took a placebo. All participants took the Mini Mental State Examination (MMSE), a widely accepted measure of memory and cognitive function, before and after the intervention. The study investigators collected cerebrospinal fluid samples before and after the intervention to measure several biomarkers associated with neurodegenerative diseases and inflammation, including amyloid beta proteins, tau, interleukin 6, chitinase-3-like protein 1 (YKL-40), and neurofilament light (NfL). YKL-40 is associated with neuroinflammation, and NfL is associated with damage to the axons of nerves in brain white matter.

The MMSE scores of the participants who took the omega-3 fatty acid supplements remained stable over the six-month intervention, decreasing by only 0.06 points, but the scores of those who took the placebo decreased by 2.0 points. The two groups' biomarkers were similar at the beginning of the intervention, but YKL-40 and NfL increased slightly in the group that received the omega-3 fatty acid supplement, indicating a possible increase in neurodegeneration and inflammatory responses. However, the increase in the two biomarkers did not correlate with the participants' MMSE scores.

Background:Studies have suggested a connection between a decrease in the levels of polyunsaturated fatty acids (PUFAs) and Alzheimer’s disease (AD). We aimed to assess the effect of supplementation with omega-3 fatty acids (n-3 FAs) on biomarkers analyzed in the cerebrospinal fluid (CSF) of patients diagnosed with AD.

Objective:To investigate the effects of daily supplementation with 2.3 g of PUFAs in AD patients on the biomarkers in CSF described below. We also explored the possible correlation between these biomarkers and the performance in the cognitive test Mini-Mental State Examination (MMSE).

Methods:Thirty-three patients diagnosed with AD were randomized to either treatment with a daily intake of 2.3 g of n-3 FAs (n  =  18) or placebo (n  =  15). CSF samples were collected at baseline and after six months of treatment, and the following biomarkers were analyzed: Aβ 38, Aβ 40, Aβ 42, t-tau, p-tau, neurofilament light (NfL), chitinase-3-like protein 1 (YKL-40), acetylcholinesterase (AChE), butyrylcholinesterase (BuChE), soluble IL-1 receptor type II (sIL-1RII), and IL-6. Results:There were no significant differences between the groups concerning the level of the different biomarkers in the CSF at baseline. Within the treatment group, there was a small but significant increase in both YKL-40 (p = 0.04) and NfL (p = 0.03), while the other CSF biomarkers remained stable.

Conclusion:Supplementation with n-3 FAs had a statistically significant effect on NfL and YKL-40, resulting in an increase of both biomarkers, indicating a possible increase of inflammatory response and axonal damage. This increase in biomarkers did not correlate with MMSE score.

Reasons why Omega-3 sometimes does not help Alzheimer's

Why Alzheimer’s studies using Omega-3 have mixed results – quality, dose size, Omega-6, genes, etc. March 2018 starts with

1. Quality of the Omega-3
      contaminants as well as the source - fish liver, salmon brain, krill, and plant
2. Dose size used (200 mg is unlikely to be as good as 2000 mg)
3. Larger dose size needed for a heavier person
      Omega-3 index would determine that
4. Larger dose size needed if much of the Omega-3 is fighting other inflammation
      Omega-3 index would determine that
5. The Omega-6 in the body can block the benefits of Omega-3
      Omega-3 index would determine that
6. Genes - Alzheimers APoE4 gene limits DHA
      additional genes may limit Omega-3, Magnesium, and Vitamin D
7. Fraction of Omega-3 EPA and DHA
8. The Omega-3 Index is a proven measure of Omega-3 for the blood - but is rarely used in trials
      Suspect that Omega-3 benefit is only seen in those who were previously deficient
      Wonder if the Omega-3 index is a good proxy measure for Omega-3 in the brain
9. Omega-3 might be less bio-available in those with poor guts/gallbladder surgery
      Omega-3 index would determine that
10. Omega-3 might not help all three forms of Alzheimer's

Alzheimers-Cognition in Vitamin D Life

Overview Alzheimer's-Cognition and Vitamin D starts with

• FACT: Cognitive decline is 19X more likely if low vitamin D
• FACT: Dementia is associated with low vitamin D levels.
• FACT: Alzheimer’s Dementia 2.3X more likely in elderly if low vitamin D – Dec 2022
• FACT: Dementia is associated with low vitamin D - many studies
• FACT: Alzheimer's Disease is 4X less likely if high vitamin D
• FACT: Every single risk factor listed for Alzheimer's Disease is also a risk factor for low vitamin D levels
• FACT: Elderly cognition gets worse as the elderly vitamin D levels get even lower (while in senior homes)
• OBSERVATION: Reports of increased vitamin D levels result in improved cognition
• OBSERVATION: Alzheimer’s patients 3X more likely to have a malfunctioning vitamin D receptor gene – 2012
• OBSERVATION: Alzheimer's Disease has been seen to halt when vitamin D was added.
• OBSERVATION: Alzheimer’s is associated with all 7 of the genes which restrict vitamin D
• OBSERVATION: 39 vitamin D and Alz. or Cognition intervention trials as of Sept 2018
• OBSERVATION: 2 Meta-analysis in 2012 agreed that Alzheimer's Disease. associated with low vitamin D
• OBSERVATION: 50X increase in Alzheimer's while decrease in vitamin D
• OBSERVATION: Vitamin D reduces Alzheimer’s disease in 11 ways
• OBSERVATION: Alzheimer’s cognition improved by 4,000 IU of vitamin D
• OBSERVATION: Plaque removed in mice by equiv. of 14,000 IU daily
• OBSERVATION: DDT (which decreases Vit D) increases risk of Alzheimer's by up to 3.8X
• OBSERVATION: 2% of people have 2 copies of the poor gene reference: Alz Org
• OBSERVATION: Genes do not change rapidly enough to account for the huge increase in incidence
• OBSERVATION: End of Alzheimer's videos, transcripts and many studies protocol has been very successful
  • It adjusts Vitamin D, B-12, Iron, Omega-3, food, etc, and can now be done at home.
• FACT: Vitamin D is extremely low cost and has very very few side effects
• CONCLUSION: Everyone concerned about cognitive decline or Alzheimer's Disease should take vitamin D
• PREDICTION MET: By 2024 Omega-3 and high dose Vitamin D will be found to reverse Alzheimer's in humans
  There are 13+ Alzheimer’s meta-analyses in Vitamin D Life
  There are 97+ Alzheimer’s studies in Vitamin D Life
  Dementia is associated with low vitamin D - many studies 50+ studies
  16+ studies in both categories Cognitive and Omega-3
