Vitamin D has increasingly become the focus of several scientific investigations as researchers seek to better understand the role that the compound plays in organ function, especially that of the brain. Now, new research indicates that vitamin D insufficiency may be associated with faster decline of cognitive function… The study, led by Joshua W. Miller, PhD, of Rutgers University, and colleagues included an ethnically diverse group of 382 older adults, from which baseline serum 25-hydroxyvitamin D (25-OHD) status, and change in subdomains of cognitive function were collected. The average age of study participants was 75.5 years, 61.8% were female, and 41.4% were white, 29.6% were African American, 25.1% were Hispanic, and 3.9% were of another race or ethnicity. At enrollment, 17.5% had dementia, 32.7% had mild cognitive impairment, and 49.5% were cognitively normal… Compared to those with adequate vitamin D levels, those with deficient or insufficient levels experienced a greater rate of decline in episodic memory and executive function over a 4.8-year follow-up. However, vitamin D status was not significantly associated with declines in semantic memory or visuospacial ability.
