People with Parkinson’s disease who have higher levels of vitamin D in their blood are less likely to experience cognitive impairment or dementia, a new study suggests.
The results provide support for future research to test whether vitamin D supplements could reduce the risk of cognitive problems for Parkinson’s patients.
The study, “Correlation between serum 25(OH)D and cognitive impairment in Parkinson’s disease,” was published in the Journal of Clinical Neuroscience.
Vitamin D plays a number of important roles, including to help regulate calcium levels and modulate nervous system activity. Prior research has linked low levels to an increased risk of falls, depression, and sleep problems in people with Parkinson’s.
