Abstract

APOE ε 4 (apoE4) polymorphism is the main genetic determinant of sporadic Alzheimer’s disease (AD). A dietary approach (Fortasyn) including docosahexaenoic acid, eicosapentaenoic acid, uridine, choline, phospholipids, folic acid, vitamins B12, B6, C, and E, and selenium has been proposed for dietary management of AD. We hypothesize that the diet could inhibit AD-like pathologies in apoE4 mice, specifically cerebrovascular and connectivity impairment. Moreover, we evaluated the diet effect on cerebral blood flow (CBF), functional connectivity (FC), gray/white matter integrity, and postsynaptic density in aging apoE4 mice. At 10–12 months, apoE4 mice did not display prominent pathological differences compared to wild-type (WT) mice. However, 16–18-month-old apoE4 mice revealed reduced CBF and accelerated synaptic loss. The diet increased cortical CBF and amount of synapses and improved white matter integrity and FC in both aging apoE4 and WT mice. We demonstrated that protective mechanisms on vascular and synapse health are enhanced by Fortasyn, independent of apoE genotype. We further showed the efficacy of a multimodal translational approach, including advanced MR neuroimaging, to study dietary intervention on brain structure and function in aging.

  • APOE4 has a negative impact on cerebral blood flow and neurovascular coupling; APOE4 mice show reduced cerebral blood flow both at baseline and in stimulus-evoked paradigms, relative to APOE3 mice.

    From Multifaceted roles of APOE in Alzheimer disease (2024) · cites this paper as [189]

    The Results (§3.2.1) report lower resting cerebral blood flow in the cortex and thalamus of 18-month-old apoE4 mice. But the controls were wild-type mice, not apoE3 mice; the Methods (§2.3) describe resting-condition measurements, not stimulus-evoked blood flow or neurovascular coupling. The Discussion (§4.1) also says cerebral blood flow was unaffected at 10–12 months. (LLM, conf=0.90)

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.
