Stem cell therapy

What does the current scientific evidence say about the safety and long-term effectiveness of stem cell therapy in improving core autism symptoms such as communication difficulties, social interaction challenges, and repetitive behaviors?

From what I’ve read, stem cell therapy for autism is still very experimental. Some small studies suggest it could be safe and maybe bring small improvements, but the research just isn’t strong enough yet to say it really works long-term. Big health agencies like the FDA haven’t approved it, so most of what’s out there is still trial-based. If someone’s thinking about it, the best step is to look for official clinical trials and talk it through with a doctor rather than going to private clinics that promise too much.
