Docosahexaenoic acid provides protection from impairment of learning ability in Alzheimer's disease model rats
Open accessAbstract
Docosahexaenoic acid (C22:6, n‐3), a major n‐3 fatty acid of the brain, has been implicated in restoration and enhancement of memory‐related functions. Because Alzheimer's disease impairs memory, and infusion of amyloid‐β (Aβ) peptide (1–40) into the rat cerebral ventricle reduces learning ability, we investigated the effect of dietary pre‐administration of docosahexaenoic acid on avoidance learning ability in Aβ peptide‐produced Alzheimer's disease model rats. After a mini‐osmotic pump filled with Aβ peptide or vehicle was implanted in docosahexaenoic acid‐fed and control rats, they were subjected to an active avoidance task in a shuttle avoidance system apparatus. Pre‐administration of docosahexaenoic acid had a profoundly beneficial effect on the decline in avoidance learning ability in the Alzheimer's disease model rats, associated with an increase in the cortico‐hippocampal docosahexaenoic acid/arachidonic acid molar ratio, and a decrease in neuronal apoptotic products. Docosahexaenoic acid pre‐administration furthermore increased cortico‐hippocampal reduced glutathione levels and glutathione reductase activity, and suppressed the increase in lipid peroxide and reactive oxygen species levels in the cerebral cortex and hippocampus of the Alzheimer's disease model rats, suggesting an increase in antioxidative defence. Docosahexaenoic acid is thus a possible prophylactic means for preventing the learning deficiencies of Alzheimer's disease.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
