Having vitamin D deficiency directly linked to dementia, study finds

A first-of-its-kind study reveals that the lack of vitamin D leads to dementia. The somber findings come from University of South Australia researchers.

Researchers investigated the association between vitamin D, neuroimaging features and the risk of dementia and stroke. The genetic research showed a direct link between dementia and a lack of the “sunlight” vitamin.

“Vitamin D is a hormone precursor that is increasingly recognized for widespread effects, including on brain health, but until now it has been very difficult to examine what would happen if we were able to prevent vitamin D deficiency,” says Elina Hyppönen, senior investigator and director of the university’s Australian Center for Precision Health, in a statement.

The study found that low levels of vitamin D were associated with lower brain volumes and an increased risk of dementia and stroke. Researchers also say that genetic analyses supported a direct casual effect of vitamin D deficiency and dementia.

“In some contexts, where vitamin D deficiency is relatively common, our findings have important implications for dementia risks. Indeed, in this UK population we observed that up to 17 percent of dementia cases might have been avoided by boosting vitamin D levels to be within a normal range,” says Hyppönen.

According to the Centers for Disease Control and Prevention, some 5 million Americans suffer from dementia. One recent study predicts that dementia cases will triple worldwide by 2050.

“Dementia is a progressive and debilitating disease that can devastate individuals and families alike,” says Hyppönen. “If we’re able to change this reality through ensuring that none of us is severely vitamin D deficient, it would also have further benefits and we could change the health and wellbeing for thousands.”

The study was published in The American Journal of Clinical Nutrition.


  1. I teach my clients about how vitamin deficiencies affect mental health and am not at all surprised by this study and the results. The human body was not made to sit inside in front of a tv or computer all day, every day. Sedentary lifestyles will kill you!!

  2. So does drinking too much coffee. So does not drinking enough coffee.
    So does this. So does that.
    “Science” comes out with conflicting information all the time. What we’re not allowed to debate this week because “the science is settled” we’re then told next week, “oops, our bad. THIS is the truth, not that.”
    We ALL know what causes dementia. It runs in families. My mother’s side has it, my dad doesn’t. Almost all my mother’s siblings died of it, but her mother didn’t. Her father was alcoholic and died before anyone would know of dementia. My mother died of it, my sister died of it. My dad died at 86, his mind and memories and thoughts still clear. Hopefully, I take after him. It’s GENETIC.
    That’s not to say there can’t be environmental or other causes too, as with any other disease.
    But it IS to say – I quit reading/listening to “science” about dementia years ago because it’s been nothing but conflicting information by people who claim to have the ultimate knowledge.
    I mean, just yesterday I read one of the newest reports that taking vitamins really does little for the vast majority of people. Who do we believe?
    And just an aside. Obviously masks don’t work or so many wouldn’t have died from COVID. We were wearing masks all over the place and the number of cases STILL went up and the number of deaths STILL went up. Hopefully VAX’s work to make the symptoms easier, but the number of cases the past few months have been record highs. With or without Vax.
    Take care of yourself, do as many mind exercises as possible, take up musical instruments, read (not science reports). And best of luck!
    And what I’m saying here has as much chance of being right as this article does. Or all the others you guys have published before.

  3. All they really had to do was sample Joe Biden’s brain (if they could find it) – no sign of Vitamin D there at all. Completely demented. Case closed, theory proven.

  4. Hope this is allowed on here if not I understand. Around age 60 I noticed that my handwriting was getting smaller and I was writing faster. I also noticed twitches on my right hand. The doctor went over my different symptoms and he suspected I’d either had a small stroke or the beginnings of Parkinson’s. After finding a neurologist and some testing I was diagnosed with Early stages of Lou Gehrig’s disease. That was 2 years ago. I took Radicava four times a day to control my symptoms, which include drooling, muscle weakness, gait problems, swallowing difficulties, and my while body feeling faint, A year ago, I began to do a lot of research and came across Health Herbs Clinic ( healthherbsclinic ) and their ALS/MND HERBAL TREATMENT. After seeing positive reviews from other patients, I quickly decided to get started on the treatment, ( NOTE: Our family doctor was informing my family to prepare for my funeral as I had a year to live at that point ), After 2 months I experienced significant reduction/decline in major symptoms, including muscle weakness, speech problems, difficulty swallowing, fatigue and others, The truth is you can get off the drugs and help yourself by trying natural methods, i live symptoms free. I’m forever thankful to nature and Health Herbs Clinic
