Partially SupportedThe ApoE4 isoform is associated with a 2-3 fold increased risk of Alzheimer's disease for the 3-4 genotype and an 8-10 fold increased risk for the 4-4 genotype.Partially SupportedAPOE4 may be protective in settings with high parasitic infection burden due to improved immune function.Not SupportedMost current beliefs about Alzheimer's disease are not useful for treatment, reversal, or prevention and may be entirely incorrect.Partially SupportedFamilial monogenic Alzheimer's disease is distinct from late-onset/sporadic Alzheimer's disease and has hindered treatment development for the latter.Partially Supported

Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

Familial monogenic Alzheimer's disease typically has a 30-50 year onset, a well-understood course, and inherited or spontaneous genetic underpinnings.

Partially SupportedThe causes of age-related dementia and familial Alzheimer's disease likely differ, necessitating separate approaches to treatment.

Partially SupportedGenes like presenilin and amyloid precursor protein are commonly involved in early-onset Alzheimer's disease.

Partially SupportedThe risk associated with apoe4 likely arises from an interaction between the gene and the modern Westernized environment.

Partially SupportedIn non-Westernized populations consuming unprocessed foods, the APOE4 genotype did not increase the risk of age-related cognitive decline or dementia and may have been protective.

Partially SupportedThe APOE4 genotype is not a risk factor for systemic insulin resistance or type 2 diabetes.

Partially SupportedA healthy lifestyle may negate the dementia risk associated with the ApoE4 genotype.

Partially SupportedAPOE4 can accelerate inflammatory responses in the brain following injury, amplifying risk.

Partially SupportedAPOE4 was the ancestral human genotype and is associated with a greater or heightened immune response compared to later genotypes.
