- Does bone well being have an effect on mind well being? In a current examine, researchers investigated the hyperlink between bone mineral density and dementia in older sufferers.
- They discovered low bone mineral density is linked to increased danger of dementia later in life.
- Additional analysis is required because the findings show a correlation, not causation.
Over 55 million folks globally have dementia. By 2050, this determine is anticipated to extend to 139 million folks.

Realizing extra in regards to the extent to which bone loss existed earlier than dementia onset might assist the event of preventive methods that optimize the well being and care of dementia sufferers.
Not too long ago, researchers examined the hyperlink between bone mineral density and dementia incidence.
They discovered that folks with low bone mineral density had been extra prone to develop dementia.
The examine seems in neurologythe medical journal of the American Academy of Neurology.
For the examine, the researchers examined healthcare knowledge from 3, 651 dementia-free individuals who underwent X-rays to evaluate their bone well being between 2002 and 2005.
The researchers additionally included demographic knowledge of their evaluation, together with training degree, smoking standing, levels of cholesterol, danger of comorbidities, and genetic danger knowledge, amongst others.
Sufferers had been round 72 years previous on common, and 57.9% had been girls. They had been adopted for round 11 years.
In the course of the follow-up, 18.8% of individuals developed dementia, of whom 76.7% developed Alzheimer’s illness.
They famous, nonetheless, that their findings contrasted
When requested what would possibly clarify the hyperlink between low bone density and dementia danger, Dr. Nahid Rianon, professor of household drugs with McGovern Medical Faculty at UTHealth Houston, not concerned within the examine, advised MedicalNewsToday:
“This can be a very beneficial examine; nonetheless, in an affiliation examine equivalent to this, we can’t be positive whether or not low bone density causes dementia, versus dementia inflicting a low bone density, versus bone density and dementia sharing a danger issue.”
“The outcomes are essential as a result of all three doable explanations are vitally vital. In the event that they share an element, for instance, it’s important to study what it’s to keep away from each lethal illnesses. However, if bone loss causes dementia, or dementia causes bone loss, it’s important to know that to forestall one deadly dysfunction from inflicting the opposite deadly dysfunction,” Dr. Rianon added.
Dr. Robert Wiggins, a neurologist at Novant Well being, additionally not concerned within the examine, agreed that it’s tough to understand how bone density could also be linked to dementia. Dr. Wiggins mentioned:
“Bone and mind well being are each depending on a posh interplay between hormonal, dietary, genetic, and different exterior, environmental components. What we all know although, is that issues like a nutritious weight-reduction plan and an energetic life-style will result in each improved bone and mind well being. Future analysis will examine whether or not there’s something inherent about low bone density that causes elevated dementia danger, or if an element widespread to each bone and mind well being is inflicting this affiliation.”
Dr. Andrew Evans, a neurologist with Novant Well being, not concerned within the examine, additionally advised MNT that low bone density and dementia could happen coincidentally from widespread causes. Dr. Evans famous:
“Each low bone density and dementia will be influenced by weight-reduction plan and train. With dementia, it’s confirmed that these actions and behaviors can have an effect on our cognitive well being. Equally, an individual with poor vitamin and train habits could have decrease bone density.”
Dr. Wiggins mentioned that as many of the sufferers included on this examine had been of their 70s and of European descent, they could not apply to different populations, despite the fact that different research have described related associations.
“(G)even this examine exhibits solely an affiliation between bone and mind well being, we’ve got to watch out to not assume that decreased bone density itself causes dementia,” he famous.
Dr. Karen D. Sullivan, a board licensed neuropsychologist and proprietor of I CARE FOR YOUR BRAIN in Pinehurst, North Carolina, not concerned within the examine, advised MNT:
“The implications of this examine are that individuals who have low bone density could also be at increased danger for creating dementia. This examine provides to the compelling physique of analysis that implies that sustaining bone well being integrity is a crucial a part of profitable getting older,” Dr. Sullivan famous.
“Proof-based methods for optimizing bone well being after age 50 embrace prioritizing high-quality animal/plant protein, polyunsaturated fatty acids, vegetables and fruit excessive in potassium, fiber, and meals excessive in calcium and vitamin D having essentially the most analysis help. Weight-loading and resistance workouts frequently are additionally wanted to maintain bones sturdy and wholesome as we get older,” she concluded.
