Alzheimer's disease features amyloid-beta plaques and tau tangles, driving neuronal loss and cognitive decline.
Stem cell therapy for Alzheimer's Disease is an investigational regenerative approach that uses living cells — such as mesenchymal stem cells and exosomes — to target the disease process. MSC and exosome protocols target neuro-inflammation and synaptic support in early-stage cognitive decline, as an adjunct to standard care. It is not an approved cure for Alzheimer's Disease: results come from early-phase clinical trials and clinic case series, not large randomised studies, and the realistic goal is slowed progression or symptom improvement rather than reversal.

Alzheimer's disease features amyloid-beta plaques and tau tangles, driving neuronal loss and cognitive decline. Stem-cell approaches address several pathways: placental mesenchymal stem cells are studied for neuroprotection — secreting anti-inflammatory and growth factors that may slow neuronal death — while exosomes derived from stem cells are explored as carriers for therapeutic molecules across the blood-brain barrier and as modulators of amyloid and tau biology. The rationale builds on evidence that stem-cell products reduce neuroinflammation and may support hippocampal neuroplasticity. Reversing established pathology and achieving adequate brain delivery remain unsolved; early trials are small and heterogeneous, with uncertain durability.

For the clinic's own description, see how Stem Plus describes its Alzheimer's Disease programme ↗.
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.
Depending on assessment, a Alzheimer's Disease protocol may draw on:
Indicative European costs are roughly €3,500–€7,000 per course; exosome-based protocols can reach €5,000–€8,000 due to manufacturing complexity. Pre/post neuroimaging (MRI, PET) adds further expense, and multi-dose protocols are common. For context, approved Alzheimer's drugs range from inexpensive symptomatic agents to costly antibody infusions — the stem-cell figure is indicative and less evidence-backed.
Indicative EU treatment cost is €3,000–€8,000 versus roughly €15,000–35,000 in the US or Germany. Build your real all-in total with the cost calculator, see the Alzheimer's Disease cost-by-country breakdown, or compare the best countries for Alzheimer's Disease →
