New Research Shows Measurable Improvements in Autism After Mesenchymal Stem Cell Infusion
Autism Spectrum Disorder (ASD) is increasingly understood not only as a neurodevelopmental condition, but as a whole-body, immune-mediated disorder. A newly published peer-reviewed study adds important clinical and neurological evidence supporting this perspective—and helps explain why regenerative medicine is gaining attention in autism care.
A 2024 open-access publication evaluated the effects of intravenous mesenchymal stem cell (MSC) infusion on both behavioral outcomes and objective brain activity, measured through electroencephalograms (EEGs). The results were consistent, measurable, and clinically meaningful.
Autism, Inflammation, and the Nervous System: The Scientific Rationale
Multiple studies have demonstrated that many individuals with autism exhibit:
- Chronic systemic inflammation
- Immune dysregulation
- Elevated inflammatory markers such as C-reactive protein (CRP)
- Imbalances in the autonomic nervous system
On EEG, this imbalance often appears as:
- Excess sympathetic ("fight or flight") activity, associated with high beta brain waves
- Reduced parasympathetic ("rest and regulate") activity, associated with theta waves
Mesenchymal stem cells are known for their immunomodulatory and anti-inflammatory signaling properties, making them a strong candidate for addressing these root biological drivers rather than symptoms alone.
Study Design: Measuring Both Behavior and Brain Function
The study included individuals with a confirmed ASD diagnosis ranging from early childhood through adulthood. Key evaluation tools included:
Behavioral Measurement
- Autism Spectrum Rating Scale (ASRS) before and after treatment
- Parent-reported global improvement assessments
Neurological Measurement
- EEG recordings taken before treatment and 2–3 months after infusion
-
Brain regions evaluated:
- • Cz (central cortex) – learning and memory
- • T3 (left temporal lobe) – auditory processing and language
- • T4 (right temporal lobe) – sensory integration and social perception
-
Analysis of:
- • Theta waves (parasympathetic activity)
- • High beta waves (sympathetic activity)
Key Findings: Consistent Neurological and Clinical Improvement
EEG Results
- 8 out of 9 measured brain regions showed an increase in theta wave activity after treatment
- This shift indicates improved parasympathetic regulation
- Neurological changes persisted for at least three months post-infusion
Behavioral Outcomes
- All patients demonstrated clinical improvement
- Mean improvement on the ASRS was 10.5 points
- Average global functional improvement was 32%
- Some individuals showed gains as high as 55–60%
Additional Observed Improvements
Families reported meaningful gains in:
Importantly, every family reported the treatment was worthwhile, and many chose to repeat therapy.
Why EEG Data Matters
One of the most compelling aspects of this study is the use of objective neurological data. Behavioral improvements are critical—but pairing them with measurable EEG changes strengthens the evidence that MSC therapy may be influencing core neurophysiological processes, not just surface-level symptoms.
This dual validation—clinical + neurological—is rare in autism research and represents a meaningful step forward.
Limitations—and Why the Findings Still Matter
The authors are transparent: the EEG subset was small. But consistency matters.
- Improvements were seen across ages
- Changes followed a clear biological pattern
- Effects aligned with known mechanisms of immune modulation
- Results mirrored findings from broader meta-analyses of stem cell therapy in ASD
In research, reproducible signals—especially across objective and subjective measures—are exactly what justify larger, more rigorous studies.
What This Means for the Future of Autism Care
The financial, emotional, and societal impact of autism continues to grow. Traditional approaches often focus on behavioral management without addressing underlying biology.
This research supports a different model:
The BetterStem Perspective
At BetterStem, this is exactly how we think about autism care.
Our approach aligns with what this study reinforces:
- 1 Address root causes, not just behaviors
- 2 Combine advanced regenerative therapies with rigorous monitoring
- 3 Use objective data alongside real-world functional outcomes
- 4 Follow patients over time to ensure durability and accountability
This publication doesn't claim a cure. What it does show is something far more important: measurable, sustained biological change paired with meaningful improvements in daily life.
That's how progress actually happens.
