Review Meta Analysis
Plasma nutrient status of patients with Alzheimer's disease: Systematic review and meta-analysis.
Alzheimer disease (AD) patients are at risk of nutritional insufficiencies because of physiological and psychological factors. Nutritional compounds are postulated to play a role in the pathophysiological processes that are affected in AD. We here provide the first systematic review and meta-analysis that compares plasma levels of micronutrients and fatty acids in AD patients to those in cognitively intact elderly controls. A secondary objective was to explore the presence of different plasma nutrient levels between AD and control populations that did not differ in measures of protein/energy nourishment. ⋯ The lower plasma nutrient levels indicate that patients with AD have impaired systemic availability of several nutrients. This difference appears to be unrelated to the classic malnourishment that is well known to be common in AD, suggesting that compromised micronutrient status may precede protein and energy malnutrition. Contributing factors might be AD-related alterations in feeding behavior and intake, nutrient absorption, alterations in metabolism, and increased utilization of nutrients for AD pathology-related processes. Given the potential role of nutrients in the pathophysiological processes of AD, the utility of nutrition may currently be underappreciated and offer potential in AD management.

The Ministry of Health, Labour, and Welfare of the Japanese national government announced a "Five-Year Plan for Promotion of Measures Against Dementia (Orange Plan)" in September 2012. This article described features of the Japanese dementia strategy in comparison with international dementia policies. ⋯ The national government should examine fundamental revisions in health, social-care services, and advocacy in joint initiatives with Alzheimer's Association Japan to improve the national dementia strategy.
