Low Plasma Vitamin E Levels Linked to Dementia and Cognitive Impairment

  “Vitamin E levels, cognitive impairment and dementia in older persons: 
the InCHIANTI study,” Cherubini A, Martin A, et al, Neurobiol Aging, 
2005; 26(7): 987-94. (Address: Institute of Gerontology and Geriatrics, 
University of Perugia Medical School, Department of Clinical and 
Experimental Medicine, via Brunamonti, Policlinico Monteluce, Padiglione 
E, Perugia 06122, Italy. E-mail: acherub at unipg.it ).

Summary:     In a population-based cohort study involving 1,033 subjects 
aged 65 years and older, low plasma levels of vitamin E were found to be 
associated with a greater probability of becoming demented and of 
suffering from cognitive impairment. Assessments were made of vitamin E 
levels (via blood samples), diet, probability of being demented, and 
probability of suffering from cognitive impairment (via clinical and 
neuropsychological examinations) in all subjects. Results found that 
after adjusting for age, gender, education, lipid levels, energy intake, 
smoking, and vitamin E intake, subjects with the lowest plasma levels of 
vitamin E (lowest tertile) had the greatest probability of becoming 
demented, with an odds ratio of 2.6, and the greatest probability of 
suffering from cognitive impairment, with an odds ratio of 2.2, as 
compared to subjects with the highest plasma levels of vitamin E 
(highest tertile). These results suggest that maintaining high plasma 
levels of vitamin E may benefit the elderly by protecting against 
cognitive impairment and dementia.
