Vitamin D and Subjective Memory Complaint in Community-Dwelling Older Adults.

Background: Older adults with hypovitaminosis D report more often subjective cognitive complaints, especially with regards to memory. This raises prospects that vitamin D may improve older adults' subjective experience of memory disorders.

Objective: To determine among older community-dwellers whether higher serum 25- hydroxyvitamin D (25OHD) concentrations were associated with fewer memory complaints, while considering different subtypes of memory complaints.
