Vitamin D Improves Mood, Cognition and Pain Tolerance

Without the sunshine vitamin, few of us would experience lives free of disease. Two new studies show that increased levels of vitamin D not only reduce the risk of developing cognitive impairments, but also improve widespread chronic pain.

 

People with higher blood levels of vitamin D live significantly longer than people who have low blood levels of the vitamin.

For the past several years, there has been considerable interest in the role vitamin D plays in improving health and preventing disease. Previous finding show that low levels of vitamin D have been directly associated with various forms of cancer and cardiovascular disease.

A new study, published in Journal of Parkinson's Disease, examined the relationship between serum vitamin D and neuropsychiatric function in people with Parkinson's disease (PD) - finding that increased levels of the sunshine vitamin are linked to improved mood and may reduce the risk of developing cognitive impairments.

Led by Dr Amie L. Peterson from the Oregon Health and Sciences University in the US, the team conducted a cross-sectional analysis of 286 patients with PD which indicated that higher serum 25-hydroxyvitamin D levels were associated with lower symptom severity, better cognition, and less depression in the entire group, but the relationships were even stronger in those who were not demented.

"About 30% of persons with PD suffer from cognitive impairment and dementia, and dementia is associated with nursing home placement and shortened life expectancy," explained Peterson. "We know mild cognitive impairment may predict the future development of dementia."

"Intervening in the development of dementia has the potential to improve morbidity and mortality in persons with PD."
