Overview:
Huntington's disease is a devastating neurodegenerative disorder that affects the brain, causing the gradual breakdown of nerve cells. Over time, it severely impacts both physical and mental abilities. Typically, symptoms begin to appear between the ages of 30 and 50 and worsen as the disease progresses.
While relatively rare in India, Huntington’s disease leaves a profound impact on those diagnosed and their families. Estimates suggest there are around 2 to 10 cases per 100,000 people in India. However, due to limited awareness and diagnosis, the actual numbers could be higher.
As researchers explore new treatment avenues, one innovative approach gaining attention is stem cell therapy for Huntington’s disease. This article dives into how this experimental treatment could change the future of care for this challenging neurodegenerative illness.

Understanding Huntington's Disease
Huntington’s disease is caused by a genetic mutation that produces a faulty version of the huntingtin protein. This leads to the progressive death of neurons in the brain, resulting in symptoms such as:
- Cognitive decline - Gradual loss of memory, focus, and decision-making ability.
- Motor dysfunction - Includes involuntary movements, muscle stiffness, tremors, and difficulty with balance and coordination.
- Emotional instability - Mood swings, depression, anxiety, and irritability are common due to changes in brain function.
- Speech and swallowing difficulties - Speech may become slurred or slow. Swallowing can become difficult, increasing the risk of choking and malnutrition.
Unfortunately, there is currently no cure for Huntington’s disease. Existing therapies only manage the symptoms, not the underlying cause.
Can Stem Cells Help with Huntington’s Disease?
The use of stem cell therapy in neurodegenerative diseases is a hot topic in medical research. In Huntington’s, stem cells may offer a way to:
- Replace lost or damaged neurons
- Promote brain regeneration
- Slow down disease progression
Stem cells, such as mesenchymal stem cells (MSCs) and induced pluripotent stem cells (iPSCs), have shown potential in preclinical trials for neurodegenerative disorders.
How Does Stem Cell Therapy Work for Huntington's Disease?
Stem cell therapy for Huntington’s disease usually involves injecting healthy stem cells into the brain or bloodstream. These cells can:
- Migrate to damaged areas
- Release neurotrophic factors to protect existing neurons
- Potentially transform into new neurons to restore lost functions
Studies have reported that some patients experienced:
- Improved motor control
- Enhanced cognitive performance
- Better emotional balance
However, outcomes can vary, and further research is necessary to establish consistent results."

Is Stem Cell Therapy for Huntington’s Disease FDA Approved?
Currently, stem cell therapy for Huntington’s disease is not FDA approved. Clinical trials are ongoing, and researchers are working to establish long-term safety and efficacy.
In India, the therapy is available at select clinics, though it remains experimental. It's crucial that patients consult with experts and understand the ethical and medical risks involved.
What Are the Benefits of Stem Cell Therapy for Huntington's Disease?
Stem cell therapy may offer several advantages for patients:
- Symptom relief: Improved motor skills, memory, and coordination
- Better quality of life: Enhanced independence and emotional well-being
- Neuroprotection: Slowing the progression of neurodegeneration
A study at NeuroGen Brain and Spine Institute in India showed improved patient outcomes, including reduced chorea (involuntary movements) and better cognitive function.
Risks and Ethical Considerations
Despite its promise, stem cell therapy for neurodegenerative diseases comes with risks:
- Immune rejection - The body may recognize transplanted stem cells as foreign and attack them.
- Tumor formation - Stem cells can potentially form tumors if they grow uncontrollably.
- Unregulated clinics offering unproven treatments - Some clinics provide unsafe, unproven therapies without scientific backing or oversight.
- Ethical concerns, especially around embryonic stem cells
