Vitamin E and Alzheimer’s Disease

Vitamin E and Alzheimer’s Disease

[Article in Japanese]

TAKE-HOME MESSAGE

  • Oxidative Stress has been suggested as a causative factor in the development of Alzheimer’s disease
  • Vitamin E, an antioxideant, has been recommended in the prevention or treatment for Alzheimer’s disease.
  • Studies have demonstrated a decrease in cognative decline for Alzheimer’s patients treated with vitamin E, but no cognative improvement for patients with mild cognative impairment.
  • Further studies are needed to establish a role for vitamin E in the treatment or prevention of Alzheimer’s disease.

Abstract

Vitamin E and Alzheimer's DiseaseIt has been suggested that oxidative stress may contribute to the pathogenesis of Alzheimer’s disease. Vitamin E is a potent antioxidant, and the results of some epidemiological studies have suggested that high intake of vitamin E through food is inversely associated with the incidence of Alzheimer’s disease. Randomized controlled studies have shown that treatment with vitamin E could delay functional decline in patients with mild to moderate Alzheimer’s disease. However, vitamin E had no cognitive benefits in patients with mild cognitive impairment or in generally healthy older women. Well-designed clinical trials or preventive interventions with vitamin E are necessary to establish its efficacy as therapeutic or preventive agents for Alzheimer’s disease.
