Vitamin D Cures Alzheimers/dementia and Depression?

Updated on January 8, 2012

Alzheimer's Disease

Can Vitamin D help cure Alzheimer's and Depression?

UCLA Scientists have discovered that a form of Vitamin D can help stimulate the immune system to clear the brain of amyloid beta, which forms the plaques concidered the cause for Alzhemias. The research findings may lead to new approaches in treating and preventing Alzheimer's bu utilising the property of Vitamin D to boost the immune system.

Vitamin D3 is an essential nutrient for immune system and bone health, it's main source is the sunshine and it is absorbed through the skin, so deficiences may occur through the winter months or in those who spend a lot of time indoors such as Alzhemia patients.

Studies show that people who suffer from depression or stress are twice as likely to develop certain types of dementia such as Alzheimers, and Researchers found that people with a high Vitamin D level wer 49 percent less likely to suffer from depression, additionaly vitamin D helps prevent dementia such as Alzheimers disease.

Alzheimers and depression may seem completely different illnesses other than the fact their both related to the brain in someway, but they show a suprising similarity in that they are both linked to low vitamin D levels.


Scientists first started the study into vitamin D after families of Alzheimer patients, reported that after having large doses of vitamin D they were acting and performing better than before, after test studys researchers believe that optimal Vitamin D levels may enhance the ammount of important chemicals in your brain and protect brain cells.

Researchers from the Manchester University also found that getting more vitamin D helps elderly people stay mentally fit, they then compared the performance of more than 3,000 men aged between 40 to 79, and found that those with low vitamin D levels preformed less well on a task designed to test mental agility.


Making sure you are getting plenty of sunlight to have healthy Vitamin D levels is a crucial factor in treating depression or keeping it at bay, Studies found that people with a low vitamin D level were eleven times more likely to suffer from depression than those who had normal levels.

Vitamin D is also essential for proper functioning of your immune system to stop inflammation, and researchers have found that depressed people have higher levels of inflammation to their brains.

So if you maintain good Vitamin D levels, your cells will function better, which will help prevent alsorts of health aliments and chronic diseases.

      Great Hub. I believe that M.S., something that only develops in people in Northern Climes such as the UK, is never caught by children who grow up closer to the equator leading researchers to speculate that it is perhaps the lack of sunshine in childhood that leads to a high rate of M.S. later. Now some kids in some areas receive regular vitamin D, I think. I seem to also remember that there was some concern about what effect the excess of vitamins might be having. My memory is a bit vague on all the details but I am of an age where I do try and pay some attention to all of this interesting research. But as you can see, I need something to sharpen the memory a little and something else to curtail the long comments I tend to leave.

      I do hope you will update this Hub if there is any new research since I think it is an area of great interest and potential savings of millions and millions of dollars to health systems if some of the research and speculation prove correct.

      I am now a follower, thanks,
