Is Stem Cell Treatment for Ataxia Effective?

Are you considering Stem Cell Treatment for Ataxia? Ataxia is a debilitating condition affecting the nervous system that has limited curative treatment options, with most focusing on symptom alleviation. Stem cell treatment is being studied as a way to change that, with early clinical studies in spinocerebellar ataxia reporting possible slowing of disease progression and improvements in neurological function in some patients (1, 2, 3, 6).

Read on to see if Ataxia Stem Cell Treatment might be right for you.

Is Stem Cell Therapy a Cure for Ataxia?

No. Stem cell therapy does not cure ataxia.

What the published studies and our own follow-up data describe is possible improvement in specific symptoms, such as balance, coordination, speech and fatigue, in some patients, though not in all. Stem cells do not correct the gene behind a hereditary ataxia, so where improvement occurs it may not be permanent, and periodic treatment may be considered in selected cases. Clinical benefit is not guaranteed, the degree of improvement differs considerably from one person to another, and the treatment remains experimental (1, 2, 3, 7, 8, 9).

What the most recent research shows

Several clinical studies have investigated stem cell treatment for ataxia and related neurological conditions, with some reporting encouraging improvements in balance, coordination and neurological function.

In a 2013 study, 16 patients with hereditary spinocerebellar ataxia received umbilical cord-derived mesenchymal stem cells through intravenous and intrathecal administration. Most patients showed improvements in balance and ataxia scores lasting at least six months, with no serious treatment-related adverse events reported during the 12-month follow-up (1). An earlier study published in 2011, involving 24 patients with spinocerebellar ataxia or multiple system atrophy-cerebellar type, also reported improvements in neurological function and daily activities following intrathecal umbilical cord MSC treatment, although more than half of the patients (14 of 24) returned to their pre-treatment condition within 1 to 14 months, on average after about three months (2). Both studies were small and had no placebo control group, but their findings suggested that umbilical cord MSC therapy might help alleviate certain symptoms of ataxia.

A recently published clinical trial in hereditary ataxia is a 2026 phase I/IIa study of ten people with hereditary ataxia (eight with Friedreich’s ataxia, one with SCA1 and one with SCA2). Each received a single intrathecal dose of their own bone marrow mesenchymal stem cells. The average score on the SARA ataxia scale fell from 14.9 to 10.36 over six months, and the reported treatment-related side effects were a mild headache in three patients and a low fever in one. The trial had no control group (the planned one was dropped because of funding limits and international sanctions), and the authors themselves state that no conclusion about efficacy can be drawn from it (report summary) (3).

One important placebo-controlled study was conducted in multiple system atrophy, a related condition that causes cerebellar ataxia. A 2012 randomized trial involving 33 patients reported that disability still worsened in both groups, but neurological deterioration was slower than in the placebo group over one year. The gap between the groups was widest at about eight months and narrowed afterwards (4). More recently, a 2026 systematic review of seven studies involving 123 patients, including this trial, found that several studies reported slower disease progression following cell-based treatment, with mostly mild and temporary side effects. Every non-randomized study in the review was rated at serious or critical risk of bias, and the studies used different cell types and treatment methods (report summary) (5).

A 2026 systematic review of 17 clinical reports, including nine involving mesenchymal stem cells, found that cell-based therapies showed encouraging short-term safety and possible improvements in neurological function in some patients. However, most studies were small and uncontrolled, and improvements were sometimes temporary. Where benefits were seen they were generally modest and often short-lived, and most studies followed patients for only one to six months (6).

Another 2026 review of the field highlighted the potential neuroprotective and anti-inflammatory effects of mesenchymal stem cells, including their ability to support existing nerve cells. These findings provide further scientific reasons to investigate stem cell therapy for ataxia, although much of the evidence for these mechanisms comes from laboratory and animal studies. The review reports that in preclinical studies, injected cells can be detected for one to four weeks, with few or no cells remaining after four to eight weeks. These findings come from experimental research and do not establish how long transplanted cells survive in patients with ataxia. However, their potential effects may last longer than the cells themselves, and the need for repeat treatment has not yet been established. It also notes that two pooled analyses of the same three small, uncontrolled clinical studies found no statistically significant overall improvement, with limited long-term safety data beyond twelve months in patients with ataxia (report summary) (7, 8, 9).

The studies so far are generally small and many remain uncontrolled. Their results are encouraging, and some controlled studies have reported possible slowing of deterioration but no reversal, although consistent long-term effectiveness has not yet been established. All of our summaries are listed on the ataxia medical reports index.

Who Is a Candidate for Stem Cell Treatment for Ataxia?

Not every form of ataxia is likely to benefit from stem cell therapy, and the first step is always an accurate diagnosis.

  • Primary ataxias are the main group we treat: These are the hereditary forms, such as spinocerebellar ataxia and Friedreich’s ataxia, and idiopathic late-onset cerebellar ataxia. They have no curative conventional treatment. However, certain types of hereditary ataxia now have approved disease-specific medications (15, 21, 22, 23, 24).
  • Acquired ataxias: Where ataxia is caused by something treatable (a vitamin B1 or B12 deficiency, hypothyroidism, excessive alcohol intake, a tumour or a stroke), treating that cause comes first, and the ataxia may improve depending on the cause and the extent of neurological damage.
  • Confirmed diagnosis: Anyone with a progressive gait disorder or imbalance should be evaluated by a neurologist. An MRI is commonly recommended as part of the evaluation, and genetic testing should be considered when hereditary ataxia is suspected or no treatable cause is found. A recent systematic review found a median genetic diagnostic rate of 43 percent in patients with suspected hereditary ataxia, although the percentage varies depending on the patients and testing methods used (10, 11). We ask for these records as part of the medical review.
  • Repeat treatment: In hereditary ataxias, improvements may not be permanent because stem cells do not influence the genetic origin of the disease. Periodic treatments may be considered following medical reassessment, although whether repeat treatment helps has not yet been tested in clinical studies (7).

Suitability is decided case by case. Every enquiry goes to our medical department, which reviews the patient’s medical condition through our online medical evaluation system and only then recommends a specific treatment location and protocol. We recommend speaking to our specialists before you decide, so that you know what can realistically be expected in your case.

How Stem Cell Therapy Works in Ataxia

Stem cell treatment involves the administration of specialized cells that have the ability to support tissue repair and communicate with other cells in the body. The MSCs used in our treatment are multipotent cells, meaning they can develop into several specialized cell types and, importantly, release biological signals that can influence surrounding tissues. In neurological disorders, their potential benefits are thought to come mainly from these biological signals rather than from directly replacing damaged nerve cells (7, 12).

In the case of ataxias and other neurological disorders, they may offer additional neuroprotection, anti-inflammatory and regenerative-supporting effects, and potentially help to reduce some of the processes involved in neurological degeneration.

Research suggests that MSCs may support neurological function through several mechanisms (7):

  • Release of neurotrophic factors: Release or stimulate the production of factors such as BDNF and GDNF that support nerve cell survival, function and communication.
  • Immune modulation: Reduce some inflammatory signals and change the activity of immune cells around injured neural tissue.
  • Promoting vascular and trophic support: Promoting the release of factors that support vascular function and tissue repair.
  • Antioxidant effects: Potentially reducing free radicals and reactive oxygen species production that could have detrimental effects on the nervous system.
  • Protection of existing neurons: MSC treatment may help protect Purkinje cells, which play a major role in balance and coordination, as demonstrated in preclinical studies (12).
  • Supporting cellular communication: MSCs release signaling molecules that may help maintain a healthier environment for surviving neurons.

Given the potential benefits reported for stem cell therapy in multiple conditions, including many genetic disorders, many studies have aimed to test the efficacy of stem cell treatment in several common forms of hereditary ataxia that lack a curative therapy – namely Spinocerebellar ataxia and Friedreich’s ataxia.

In patients with hereditary ataxias, studies of stem cell therapy have reported or are investigating the possibility that it may (1, 2, 3, 7, 12):

  • Help slow disease progression in some patients
  • Help protect cerebellar neurons from further damage
  • Support the function and survival of existing nerve cells
  • Improve motor skills, balance, and coordination
  • Support nervous tissue functioning and daily activity, with possible improvements in alertness and fatigue reported by some patients
  • Possibly reduce pain in certain patients, although evidence for this particular benefit remains limited
  • Modulate immune and inflammatory responses that may contribute to neurological damage

In general, stem cell therapy has been shown to be well-tolerated in people with ataxia, with minimal side effects that are easily managed and rarely cause significant problems. Some patients report noticing an improvement within around two weeks of stem cell transplantation, although this differs from person to person. The degree of improvement varies considerably between patients. Some may notice changes in specific symptoms, while others may experience little or no improvement (1, 2, 3, 6).

Additionally, stem cell therapy acts through several mechanisms at once and may provide a range of potential benefits that are difficult to obtain through conventional treatment methods that require multiple modalities because each drug usually targets one aspect of the disease. This doesn’t in any way say that stem cell therapy can be used as a single treatment modality since we still recommend physiotherapy and other forms of treatments in our center, but it simply states the possible advantages of stem cell therapy over conventional modalities.

Few conventional treatment options are available for patients diagnosed with ataxia, which mostly focus on alleviating the symptoms. Although some disease-specific treatments are now available, many progressive forms of ataxia still lack effective treatments capable of preventing neurological degeneration. Stem cells are being investigated for their potential neuroprotective and regenerative-supporting effects, which may help improve certain symptoms and neurological functions in some patients (6, 7, 8, 9).

Possible improvements after Stem Cell Therapy for Ataxia

The purpose of our stem cell treatment is to support neurological function and potentially improve the symptoms associated with ataxia through the possible neuroprotective and immunomodulatory effects of stem cells. Thus, various kinds of improvement are possible after our treatment and our past patients have reported the following*:

Based on follow-up reports from 143 patients across 415 forms, here is the percentage who self-reported any improvement after treatment.

Symptom % of Patients who noticed Improvement % who noticed a Small Improvement % who noticed a Moderate Improvement % who noticed a Significant Improvement
Speech (babbling for infants) 83% 27% 29% 27%

Patients self-assess each symptom on a 5-point scale (Worse / No improvement / Small / Moderate / Significant) at follow-up checkpoints after treatment, comparing to their pre-treatment baseline. "Reported improvement" combines the small, moderate and significant buckets. Data is updated daily from our internal patient registry. As with any medical treatment, past results do not guarantee future outcomes — improvements vary from patient to patient.

*It is important to remember that improvements experienced by patients diagnosed with hereditary ataxias may not be permanent, as stem cell treatments do not currently have any influence on the genetic origin of these specific types of ataxia. In such cases, periodic treatments may be considered following medical reassessment. Finally, as for any medical treatment, improvements cannot be guaranteed.

Safety, Side Effects and Cell Quality Control

Like any medical treatment, stem cell therapy can have side effects. Many of the short-term reactions reported are similar to those that can occur after an IV infusion or injection, such as fever, headache, nausea, temporary discomfort, or an allergic or immune reaction. Intrathecal administration also involves a lumbar puncture and may cause temporary procedure-related symptoms such as headache, back discomfort, nausea or vomiting. In general, stem cell therapy has been reasonably well tolerated in early clinical studies involving patients with ataxia, with side effects that are usually mild and can be managed medically (3, 6, 13, 14).

In the 2026 hereditary ataxia trial described above, three of ten patients had a mild headache and one a low fever after the intrathecal injection, with no severe events over six months (report summary) (3). The 2026 review of multiple system atrophy studies reported fever after MSC treatment, and mild headache and fever in studies using cord blood cells. It also reported small ischaemic lesions on MRI after delivery of cells through an artery, a route we do not use, although these occurred at a similar rate in patients given placebo and were attributed to the procedure rather than the cells. In one study using intrathecal stem cell injections, MRI scans showed thickening or mild enhancement of the nerve roots in the lower spine in every patient who received the medium or high dose. About half of these patients had low back or leg discomfort, which persisted in two and led the investigators to stop the highest dose, but none developed neurological deficits (report summary) (5, 14). Long-term safety data remain limited.

Our protocol delivers cells both intravenously and by intrathecal injection, which is performed after a lumbar puncture, a procedure with its own risks (most commonly headache and back pain afterwards), which the treating physicians go through with you before you consent.

On the cells themselves: mesenchymal stem cells and umbilical cord blood stem cells have been studied for safety, and unlike embryonic stem cells, they have not shown the same tendency to form tumours in clinical studies to date (study). In randomised trials of intravenous umbilical cord MSCs, no increase in cancer has been seen so far, although most trials followed patients for a year or less and longer follow-up is still needed (13).

Every batch of cells is screened, tested twice and traceable by code before it is released for use. The full process is described on our standards and certifications page.

Where Treatment Happens, and Under Which Regulations

Treatment is delivered at affiliated hospitals in Bangkok, Thailand and in Dongguan, China. It is not approved by the US Food and Drug Administration and is not offered in the United States. It is given under Thai and Chinese regulations for cell therapy, and the cells are prepared in laboratories with CNAS, GMP and ISO accreditation. The accreditation details and the certificates are on our standards and certifications page.

Our Treatment Program in Details

Beike is unlike any other stem cell treatment provider in the world, the reason? Since 2005, we have been developing and optimizing our stem cell treatment protocols with the concept that a comprehensive treatment approach may provide more individualized support for our patients.

We believe that stimulation through various therapies is necessary to enhance stem cell regenerative response, therefore our protocols include daily therapies to support the stem cells. Finally, we provide a wide variety and large quantities of stem cells in order to adapt to each patient specific condition and deliver maximized regenerative potential.

Our ataxia treatment consist in 6 to 8 simple and minimally invasive injections of umbilical cord derived stem cells. The stem cells are transplanted using two separate methods: by intravenous way using a standard IV drip system, and through intrathecal injection performed after lumbar puncture. These two delivery methods allow for increased efficacy while ensuring safety and minimum inconvenience for the patient.
