Nutritional
biomarkers in Alzheimer's disease: the association between
carotenoids, n-3 fatty acids, and dementia severity.
...
Carotenoids are fat-soluble antioxidants that may protect
polyunsaturated fatty acids, such as n-3 fatty acids from
oxidation, and are potentially important for Alzheimer's
disease (AD) prevention and treatment... Moderately severe AD
patients (MMSE=16-19) had much lower plasma levels of two
major carotenoids: lutein and beta-carotene, compared to mild
AD patients (MMSE=24-27) or controls...

Plasma carotenoid levels and
cognitive performance in an elderly population: results of
the EVA Study
...
METHODS: We examined, in a cross-sectional analysis, the
relationship between cognitive performance (assessed by the
Mini-Mental State Examination, Trail Making Test Part B, Digit
Symbol Substitution, Finger Tapping Test, and Word Fluency
Test) and different plasma carotenoids (lutein, zeaxanthin,
beta-cryptoxanthin, lycopene, alpha-carotene, and
trans-beta-carotene and cis-beta-carotene) in a healthy
elderly population (the EVA,"Etude du Vieillissement
Artériel," study; n = 589, age = 73.5 +/- 3 years).
RESULTS:
Logistic
regression showed that participants with the lowest cognitive
functioning (<25th percentile) had a higher probability of
having low levels of specific plasma carotenoids (<1st
quartile): lycopene and zeaxanthin.
...
CONCLUSION: Even if it is not possible to affirm if these low
levels of carotenoids precede or are the consequence of
cognitive impairment, our results suggest that low carotenoid
levels could play a role in cognitive impairment. The
biological significance of our findings needs further
research.
