Background Elderly dementia patients are prescribed cholecalciferol (vitamin D) when institutionalized in one of our wards. We follow guidelines from the Dutch Health Council, which are evidence-based. No large-scale research, or guidelines are available on vitamin D deficiency and suppletion in institutionalized patient with HD, Korsakov’s syndrome or Acquired Brain Injury. Chel et alfound high prevalence of vitamin D deficiency and insufficiency among 28 patients in a Dutch Skilled Nursing Facility.
Method In 21 institutionalized HD patients we did blood tests to determine the level of vitamin D (serum 25(OH)D level). In these patients, blood samples had to be drawn for other indications, and the vit D level was assessed at the same time.
Aim Assess the prevalence and level of vitamin D deficiency in our institutionalized HD patients.
Results We found deficiency in all patients included. Mean was 25 nmol/l. Range was 3 – 51 nmol/l (rev. 50-150 nmol/l). Some of these patients are on a high kcal diet, adding drinks/meal replacements with added vitamins to their daily intake.
Conclusions Vitamin D deficiency is common in advanced HD.
Recommendations We recommend lab tests on admission, and prescribe monthly vitamin D to all HD patients with deficiency. In severe deficiency a weekly dose is given for three months. Contra indications (sarcoidosis, hyperkalemia, hyperparathyroidism) should be taken into account by prescribers. Exposure to the sun on a daily basis for at least 30 minutes is not always realistic, but advisable.

Alzheimers-Cognition - Overview has the following summary on VitaminDWiki
- FACT: Cognitive decline is 19X more likely if low vitamin D
- FACT: Dementia is associated with low vitamin D levels.
- FACT: Alzheimer’s 21 % more likely if low vitamin D
- FACT: Alzheimer's Disease is 4X less likely if 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: 39 vitamin D and Alz. or Cognition lntervention 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
- 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: By 2024 Omega-3 and high dose Vitamin D will be found to reverse Alzheimer's in humans
- As of 2018 that combination has worked well with Multiple Sclerosis, Sleep, and Cluster Headaches
