Which countries run stem-cell trials for Alzheimer's Disease?

Country distribution

A study with sites in several countries is counted once per country, taken from the location block of each registry record.

What the map means for Alzheimer's Disease

Dementia cell research follows imaging and biomarker infrastructure: centres able to run PET, standardised CSF assays and repeated neuropsychological testing. That concentrates studies in a small number of countries and makes 'we treat Alzheimer's with stem cells' offers in low-infrastructure settings hard to reconcile with the science they cite.

Where recruitment is actually open

What travelling for a trial actually involves

Before treating a foreign site as an option, confirm the follow-up burden in writing. Trials measure outcomes on a schedule; missing those visits makes the data unusable and leaves you outside the safety net the protocol provides.

Multi-country studies, named

Registered studies with sites in more than one country — the clearest evidence of collaboration rather than a single-centre series.

Why trial geography is not a shortlist

Where studies happen reflects who funds and who authorises them. Treating that as a ranking of care quality confuses the research system with the treatment market, two things that overlap far less than medical-tourism marketing implies.

Before treating geography as a shortlist, read the legality overview by country and what "best country" actually means here.

When these studies started

Registrations by start year since 2020: 2020 (4), 2021 (1), 2023 (2), 2025 (4), 2026 (9). Activity for this condition spans 2009 to 2026, which shows whether interest is growing, flat or past its peak.

Frequently asked

Which countries run stem-cell trials for Alzheimer's Disease?

Sites are registered in 10 countries; the largest is United States (~45% of country mentions, 2026-08-29).

Does a country with many trials mean better treatment there?

Volume tracks funding and law, not outcomes. The relevant question is what oversight covers the specific clinic and product you are considering.

Are trial sites and commercial clinics the same thing?

Mostly no. Some clinics imply an association with local research institutions; the registry record names the actual sponsor and site, which settles it.
