Background: Nutritional status often deteriorates in Alzheimer’s disease (AD). Less is known about whether nutritional care reverses malnutrition and its harmful consequences in AD. The aim of this study is to examine whether individualized nutritional care has an effect on weight, nutrition, health, physical functioning, and quality of life in older individuals with AD and […]

A high incidence of fractures, particularly of the hip, represents an important problem in patients with Alzheimer disease (AD), who are prone to falls and have osteoporosis. We previously found that vitamin K deficiency and low 25-hydroxyvitamin D (25-OHD) with compensatory hyperparathyroidism cause reduced bone mineral density (BMD) in female patients with AD. This may […]

Background: To our knowledge, no prospective study has examined the association between vitamin D and cognitive decline or dementia.; Methods: We determined whether low levels of serum 25-hydroxyvitamin D (25[OH]D) were associated with an increased risk of substantial cognitive decline in the InCHIANTI population-based study conducted in Italy between 1998 and 2006 with follow-up assessments […]

Objective: To test the hypothesis that lower 25-hydroxyvitamin D [25(OH)D] levels are associated with a greater likelihood of cognitive impairment and risk of cognitive decline.; Methods: We measured 25(OH)D and assessed cognitive function using the Modified Mini-Mental State Examination (3MS) and Trail Making Test Part B (Trails B) in a cohort of 1,604 men enrolled […]

Background: Serum vitamin D concentrations are associated with global cognitive function among older adults. The benefits of vitamin D intake to treat or prevent cognitive impairment remain unknown. The objective of this cross-sectional study was to determine whether weekly dietary intake of vitamin D could be associated with global cognitive performance among older adults.; Methods: […]

Background: Hypovitaminosis D has been cross-sectionally associated with dementia and stroke. The objective of this longitudinal study was to determine whether serum vitamin D deficiency at baseline could predict the onset of non-Alzheimer dementias (NAD) within 7 years among older women.; Methods: Forty high-functioning older women (78.4 years, 76.4/82.0; median, 25th/75th percentile) from the EPIDOS […]
