Alzheimer's stem-cell 'success' claims are hard to verify. Small unblinded cohorts report 'stabilisation' or modest gains in 30–50% of patients, but the disease naturally fluctuates and concurrent therapies confound results. Exosome trials often report biomarker shifts without documented cognitive benefit. Realistically, any effect would be slowing of decline in a subset, not restoration of lost memory.
Forty-one registered trials and 9 recruiting studies investigate stem-cell therapy in Alzheimer's. Small cohorts describe modest cognitive-score changes over 6–12 months; most are uncontrolled. Some show shifts in cerebrospinal-fluid or PET amyloid/tau markers, with less consistent functional gains. No trial has prevented decline or shown reversal of neuronal loss. Approved amyloid-targeting antibodies (lecanemab, aducanumab) show modest slowing of early decline — stem-cell benefit is not proven to match them.
