Study Links Between Cognitive Problem In Older Adults And Low Vitamin D Levels

Recently researchers found link between deficiency of vitamin D and cognitive problems in large scale in older adults.

The important part of these findings is the connection between cognitive problems and dementia.

It seems that people with impaired cognitive function are more susceptible to develop dementia.

In this study, researchers intervened almost 2000 adults aged over 65. The cognitive function levels of the participants were thoroughly assessed and came to conclusion that as the levels of vitamin decrease, the levels of cognitive impairment went up.

Persons with lowest levels of vitamin D are almost twice at risk of developing cognitive impairment.

Vitamin D plays crucial role in maintaining better bone health for humans and also it helps in the absorption of calcium and phosphorus and helps in functioning of body immune system.

Foods that are fortified with vitamin D, exposure to sunlight and certain foods like oily fish are 3 main important sources of Vitamin D. For older people who are facing problem with low levels of vitamin D the one main important problem could be capacity of their skin to absorb Vitamin D from sunlight.

The Alzheimer’s Society estimated that almost 700,000 individuals in UK are affected with dementia and it is also predicted that this number would certainly rise to nearly 1 million by 2025.

Almost two thirds of these particular figures of dementia are women and almost 60,000 deaths every year are attributed to this particular condition.

Dr. Lain Lang from the Peninsula Medical School, who worked on the study, concluded that dementia is growing problem for health sciences and people with low levels of vitamin D are more susceptible for cognitive impairment and consequently to dementia.
