Cats and dogs get dementia. Here’s how to spot signs and support pets - Aug 2023
Washington Post Vitamin D is NOT mentioned
- Experts aren’t sure how many companion animals suffer from dementia. Estimates range from 14 to 35 percent of the pet dog population age 8 and older, according to one study. Another study suggests nearly one-third of cats ages 11 to 14 and 50 percent of cats 15 and older are affected. Many experts believe these numbers are probably conservative."

Evaluation of cognitive function in the Dog Aging Project: associations with baseline canine characteristics
Scientific Reports volume 12, Article number: 13316 (2022)
Sarah Yarborough, Annette Fitzpatrick, Stephen M. Schwartz & Dog Aging Project Consortium
Canine cognitive dysfunction (CCD) is a neurodegenerative disease in aging dogs. It has been described previously in relatively small cohorts of dogs using multiple different rating scales. This study aimed to use a minimally modified CCD rating scale developed by previous researchers to describe the prevalence of CCD more thoroughly in a large, nationwide cohort of companion dogs participating in the Dog Aging Project (DAP) (n = 15,019). Associations between various canine characteristics, predicted lifespan quartiles, and CCD were examined using univariable and multivariable logistic regression models and receiver operating curve (ROC) analysis. When controlling for all other characteristics, the odds of CCD increased 52% with each additional year of age. Among dogs of the same age, health status, breed type, and sterilization status, odds of CCD were 6.47 times higher in dogs who were not active compared to those who were very active. When controlling for age, breed type, activity level, and other comorbidities, dogs with a history of neurological, eye, or ear disorders had higher odds of CCD. Lifespan quartile analysis showed excellent discriminating ability between CCD positive and negative dogs. Weight-based lifespan quartile estimation could therefore serve as a tool to inform CCD screening by veterinarians.

VitaminDWiki - 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. $75/month.
- 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
