Charts of impact of Vitamin D

PDF Table of Contents

Neurological disorders are the major cause of disability, leading to a decrease in quality of life by impairing cognitive, sensorimotor, and motor functioning. Several factors have been proposed in the pathogenesis of neurobehavioral changes, including nutritional, environmental, and genetic predisposition. Vitamin D (VD) is an environmental and nutritional factor that is widely distributed in the central nervous system's subcortical grey matter, neurons of the substantia nigra, hippocampus, thalamus, and hypothalamus. It is implicated in the regulation of several brain functions by preserving neuronal structures. It is a hormone rather than a nutritional vitamin that exerts a regulatory role in the pathophysiology of several neurological disorders, including Alzheimer's disease, Parkinson's disease, epilepsy, and multiple sclerosis.
A growing body of epidemiological evidence suggests that VD is critical in neuronal development and shows neuroprotective effects by
influencing the production and release of

• neurotrophins,
• antioxidants,
• immunomodulatory,
• regulation of intracellular calcium balance, and
• direct effect on the growth and differentiation of nerve cells.

This review provides up-to-date and comprehensive information on vitamin D deficiency, risk factors, and clinical and preclinical evidence on its relationship with neurological disorders. Furthermore, this review provides mechanistic insight into the implications of vitamin D and its deficiency on the pathogenesis of neurological disorders. Thus, an understanding of the crucial role of vitamin D in the neurobiology of neurodegenerative disorders can assist in the better management of vitamin D-deficient individuals.

VitaminDWiki - Overview Parkinson's and Vitamin D contains

• Vitamin D associated with Parkinson’s Disease in 55 studies, more studies needed- March 2022
• Parkinson's category has 112 studies
• Parkinson’s Disease and Vitamin D – review of 52 studies – May 2022
• Parkinson patients: 60 % taking Vitamin D – Dec 2019
• Low Vitamin D increases Parkinson's by 3X– July 2010 "only" a 30 year test, need more study
• Parkinson's disease prevented by Vitamin D, but small doses do not treat it - Aug 2023
• 10 clinical trials for PD with vitamin D intervention as of June 2023
• Parkinson’s Disease Summer School – alternative therapies included 60-80 ng of Vitamin D – Sept 2019
• Associated with PD are: Meta-analyses (12 ), Cognition (22 studies), Multiple Sclerosis (17 studies), VIRUS (4 studies), Omega-3 (3 studies), Vitamin D Receptor (11 studies)
• Note by the Founder of VitaminDWiki: I have twice recommended lots of Vitamin D to treat PD. Both got much better, but one had his doctor him cut back to just 2,000 IU. All of his recovery got reversed. With lots of vitamin D he could sing and bike, but now he can barely talk or walk

VitaminDWiki – Overview MS and vitamin D contains

Clinical interventions have shown that Vitamin D can prevent, treat, and even cure Multiple Sclerosis, at a tiny fraction of the cost of the drugs now used to treat it, and without side effects.

• Fact: Low Vitamin D results in higher risk of getting MS
  Increase latitude leads to decreased Vitamin D, which leads to increased risk of MS
  
  
  There is less of an effect recently - air conditioning now allows people to stay indoors

  
  
  Dark skinned people are far more likely to get MS (dark skin people typically have low vitamin D)
  Elderly (who typically have low vitamin D) are more likely to get MS
  Is there increased risk in people who already have diseases associated with low vitamin D - TB, for example ? ? ?
  Women typically have 3X increased MS risk then men (note: women typically have 20% lower levels of vitamin D than men)
     Exception: women in very sunny climates and dark-skinned women have the same MS risk as men
  Obese are 60% more likely to get MS
  Multiple Sclerosis 42X more likely if light brown skin and smoke (both associated with low vitamin D) – July 2020
  MS recurrence is much higher in spring - the lowest time of the year for vitamin D
  increase in clouds/rainfall (which reduces available Vitamin D) is associated with increased risk of MS (Scotland, Western Washington)
  MS incidence has increased 70% in a decade while the incidence of vitamin D deficiency doubled
  Less MS in those with outdoor occupations PDF file, not a web page
• Fact: MS uses up Vitamin D
• Fact: Lower vitamin D (due to MS using up Vitamin D while fighting the disease) results in many other health problems (such as broken bones), so depleted vitamin D levels must be restored.
  
  Fact: Increasing levels of Vitamin D is associated with lower MS risk, as well as lower risk of many other diseases

  
• Fact: Vitamin D looks so promising for preventing and treating MS that there were 25 INTERVENTION clinical trials as of Feb 2014
• Fact: Vitamin D reduced the MS relapse rate far better than Fingolimod which is now used for that purpose.
  • Note: Fingolimod costs $25,000/year while vitamin D, which works better and has no side effects is 1000 times less expensive.
• Fact: 98% of the genes affected by Interferon are also affected by Vitamin D
  • Note: 1 week of Interferon = $4,700, 1 week of vitamin D 10,000X lower cost
• Fact: MS Doctors in Brazil recommending 40-100 ng/mL of Vitamin D
• Fact: Many MS forums are recommending vitamin D to treat MS, with some taking 5,000 to 10,000 IU daily
  Observation: Risk of going from pre-MS to MS reduced 68 percent with 7100 IU vitamin D – RCT Dec 2012
  • This is an observation instead of a fact - it has not yet been confirmed.
• Fact: VERY LARGE doses of vitamin D have CURED 2,000 people of MS in Brazil
• Controversy: UVB fron sunlight or UVB bulb may be BETTER than Vitamin D for reducing the risk of getting MS
• Hypothesis: In addition to Vitamin D there are many other photoproducts produced by UVB that may promote health.

Summary: lack of consensus on how much to prevent, treat, or cure MS.

• How much Vitamin D to prevent many diseases - such as MS
• How much Vitamin D is needed to treat MS? There is currently no agreement
     The recommendations range from 40 to 100 ng - which can result of a dose ranging from 3,000 to 20,000 IU/day
• How Vitamin D is needed to Cure MS?: It appears that 20,000-140,000 IU daily may be needed to CURE the disease
     You must be under the supervision of a doctor who knows what to watch for in your individual situation.
     High doses of Vitamin D cannot be used as a monotherapy.
     You will need to adjust the cofactors: Typically increasing Magnesium and Vitamin K2, and reducing Calcium intake.
     Your doctor will monitor these and might increase your intake of Vitamins B2, C, as well as Omega-3899
• Epstein-Barr virus increases risk of Multiple Sclerosis by 32X - Jan 2022
• Multiple Sclerosis treated by Vitamin D, recommends investigating high dose Coimbra - Oct 2021
• Multiple Sclerosis patients had fewer COVID-19 problems (Note: many MSers take Vitamin D) – April 30, 2021
• Vitamin D Resistance hypothesis confirmed by Coimbra high-dose vitamin D protocol – April 2021
• Multiple Sclerosis relapses cut in half by 100,000 IU of Vitamin D every 2 weeks– RCT 2019

VitaminDWiki – Overview Epileptic children and Vitamin D category contains

Fact: Anti-Epilepsy drugs lower vitamin D levels
Fact: Epilepsy 5X more likely if preterm
Fact: Preterm greatly decreased if add vitamin D and/or Omega-3
Fact: Vitamin D supplementation increases Vitamin D levels
Recommendation: Epileptics should take vitamin D to:
    Reduce the number of seizures (restore vitamin D then take maintenance dose of at least 5,000 IU daily)
   Avoid having health problems associated with low vitamin D, such as low bone density
1 study: Epileptics have low vitamin D levels before starting treatment

Epilepsy = 4,000 years of ignorance, superstition and stigma
   followed by 100 years of knowledge, superstition and stigma.
