Claim by claim

The article's claims are listed below. Without a confirmed source study, they have not been assessed as supported or unsupported.

Claim 1 of 5Not checkedPatients with early-onset Alzheimer's disease have more extensive deposits of tau than patients whose symptoms start at age 65 or older.View evidenceHide evidence

Not checked

No source study was confirmed for this article. This claim remains unverified, rather than assessed as supported or unsupported.

Claim 2 of 5Not checkedTau accumulates at more than twice the rate in younger patients compared with older patients and spreads widely throughout the brain.View evidenceHide evidence

As statedmore than twice the rate

Not checked

No source study was confirmed for this article. This claim remains unverified, rather than assessed as supported or unsupported.

Claim 3 of 5Not checkedThe findings may help explain why early-onset Alzheimer's typically progresses faster and is more likely to produce unusual syndromes involving language, visual and spatial abilities, and executive functioning.View evidenceHide evidence

Not checked

Claim 4 of 5Not checkedThe study included 390 early-onset patients from the Longitudinal Early-Onset Alzheimer's Disease Study and 211 late-onset patients from the Alzheimer's Disease Neuroimaging Initiative, all with mild cognitive impairment or mild dementia due to Alzheimer's and amyloid PET evidence; a subset had repeat tau PET scans over about two to three years.View evidenceHide evidence

As stated390 early-onset patients; 211 late-onset patients; average follow-up of two to three years

Not checked

Claim 5 of 5Not checkedThe article says the study did not test Alzheimer's treatments, but its results raise questions about whether younger patients might respond differently and whether tau-targeting therapies could be especially important in early-onset Alzheimer's.View evidenceHide evidence
