To elucidate the possible role of carotenoids and vitamin A as risk factors for Alzheimer's disease (AD), we compared serum levels of β‐carotene and α‐carotene, and vitamin A, measured by isocratic high performance liquid chromatography, of 38 AD patients and 42 controls. The serum levels of α‐carotene did not differ significantly between AD patients and control groups. However, the serum levels of β‐carotene and vitamin A were significantly lower in the AD‐patient group. These values did not… 

Nutritional biomarkers in Alzheimer's disease: the association between carotenoids, n-3 fatty acids, and dementia severity.

The association between higher carotenoids levels and DHA and higher MMSE scores, supports a protective role of both types of nutrients in AD and suggest targeting multiple specific nutrients, lutein, beta-carotene, and D HA in strategies to slow the rate of cognitive decline.

Vitamin A and Alzheimer's disease

The inhibitory effects of vitamin A and β‐carotene on the oligomerization of Aβ40 and Aβ42 in’vitro are shown, which suggest these vitamins could be key molecules for the prevention and therapy of AD.

Dietary antioxidants and dementia in a population-based case-control study among older people in South Germany.

It is found that blood vitamin C and β-carotene concentrations were significantly lower in demented than in control persons even after adjusting for school education, intake of dietary supplements, smoking habits, body mass index, and alcohol consumption.

Antioxidant vitamin intake and risk of Alzheimer disease.

Investigation of the relationship between AD and the intake of carotenes, vitamin C, and vitamin E in 980 elderly subjects in the Washington Heights-Inwood Columbia Aging Project found that intake of these vitamins was not associated with a decreased risk of AD.

The Impact of Vitamin E and Other Fat-Soluble Vitamins on Alzheimer´s Disease

Current knowledge about vitamin E and the other lipophilic vitamins A, D, and K, their status in AD patients, their impact on cognitive functions and AD risk, as well as their influence on the molecular mechanisms of AD are summarized.

Dietary and Serum Level of Antioxidants in the Elderly with Mild Impaired and Normal Cognitive Function: A Case-Control Study

The subjects with mild cognitive impairment had a significantly lower serum levels of lycopene beta-carotene antioxidants compared with healthy subjects, and there was a positive correlation between serum level of vitamin C and Lycopene and also vitamin C dietary intake and scores in the MMSE-12 test.

Vitamin D and Its Analogues Decrease Amyloid-β (Aβ) Formation and Increase Aβ-Degradation

Vitamin D and analogues decreased β-secretase activity, not only in mouse brains with mild vitamin D hypovitaminosis, but also in non-deficient mouse brains, suggesting that supplementation of vitamin D or vitamin D analogues might have beneficial effects in AD prevention.

Carotenoids and Neurobiological Health.

This chapter discusses the impact of carotenoids on neurological health by first reviewing their chemical characteristics, dietary sources, and general mechanisms of action before examining in some detail the available evidence for a protective role for various carOTenoids in neurodegenerative disease.

Plasma concentrations of vitamins A and E and carotenoids in Alzheimer's disease.

In a case/control study, serum concentrations of vitamins A and E and major carotenoids were determined in patients with Alzheimer's disease, multi-infarct dementia and control subjects. The results

The focus is on the ability of beta-carotene to function as a chain-breaking antioxidant in a lipid environment at physiological O2 partial pressures, the mode considered most likely to operate in mammalian cells.

Clinical diagnosis of Alzheimer's disease

The criteria proposed are intended to serve as a guide for the diagnosis of probable, possible, and definite Alzheimer's disease; these criteria will be revised as more definitive information becomes available.

Lipid peroxidation and free radical scavengers in Alzheimer's disease.

The results showed a statistically significant decrease in the levels of GSH-Px, vitamins E, C and A, zinc, transferrin and albumin in the SDAT group, suggesting an alteration of free radical scavengers in the malnourished subgroup of theSDAT population could combine the radical and nutritional hypothesis advanced by some authors.
