Understanding Ataxia SCA 15

Ataxia SCA 152

Population Estimate:  Fewer than 1000 people in the U.S. have this disease.

Imagine waking up one day and finding it increasingly difficult to control your movements. Simple tasks like walking, writing, or even eating become monumental challenges.  This is the harsh reality for those living with ataxia, a group of neurological disorders that affect coordination and balance.

The description above is what CAN happen to people.  But for me, I cannot remember a time when I didn’t have issues with coordination.  Honestly, I have never known what the feeling is like to walk and run without some struggles.  But this article is not about my struggles, as I have tried and will continue to share my story with this community.  But it is about bringing awareness to my specific type of Ataxia.

What Is Ataxia SCA 15?

Spinocerebellar Ataxia Type 15 (SCA 15) is a rare and progressive neurological disorder that primarily affects a person’s cerebellum, the region of the brain responsible for coordination and balance.  Like other forms of ataxia, SCA 15 leads to a range of debilitating symptoms, gradually robbing individuals of their ability to perform everyday tasks.

Symptoms of Ataxia SCA 15

Loss of Coordination: The hallmark symptom of SCA 15 is a progressive loss of coordination and balance.  This often leads to unsteady walking, difficulty with fine motor skills, and clumsiness in daily activities.

Slurred Speech: Individuals with SCA 15 may develop slurred speech, making communication challenging and potentially affecting your quality of life.

Muscle Stiffness: Muscle stiffness, also known as spasticity, can be another symptom, making it difficult to move smoothly.

Involuntary Movements: Some people with SCA 15 experience involuntary movements, such as tremors or jerky motions. 

Eye Movement Problems: Eye coordination issues, including nystagmus (involuntary eye movement), can also occur in SCA 15, affecting vision.

Cognitive Changes: While primarily a movement disorder, SCA 15 can sometimes lead to cognitive changes, including memory and attention problems.

Causes of Ataxia SCA 15

SCA 15, like other types of Spinocerebellar Ataxia, is a genetic disorder.  It is caused by mutations in specific genes that result in the abnormal production of proteins essential for the cerebellum’s function.  In the case of SCA 15, the mutation is related to the ITPR1 gene, which encodes a protein involved in regulating calcium levels in nerve cells.

This form can be inherited in an autosomal dominant manner, meaning that an affected individual has a 50% chance of passing the mutated gene on to their children.  Genetic counseling can be valuable for individuals with a family history of SCA 15 to understand their risk and make informed decisions.

I recently had a discussion with a genetic counselor and each time I have a conversation, I learn new information.  Both of my parents were tested, and both came back negative.  That means as I was forming and replicating my own cells, something happened, and I was missing certain gene sequencing. 

Diagnosis and Management

Diagnosing SCA 15 typically involves a combination of clinical evaluation, genetic testing, and neurological examinations.  There is no cure for SCA 15 at present, and treatment primarily focuses on managing symptoms and improving the individual’s quality of life.  This may involve physical therapy to maintain mobility, speech therapy for communication difficulties, and medications to alleviate symptoms like spasticity.

Hope for the Future

While SCA 15 remains a challenging condition with no cure, there is hope on the horizon. Advances in genetic research and neurology are opening new possibilities for treatment and even potential cures for genetic disorders like SCA 15.

Gene therapy and CRISPR technology, for instance, hold promise in correcting the underlying genetic mutations responsible for SCA 15.  Researchers are working tirelessly to develop targeted therapies that can slow or halt the progression of the disease, potentially improving the lives of those affected.

But here is where I need more awareness for this specific form.  Since it is so rare and generally a milder form, researchers tend to focus more on the severe types of Ataxia.  As well as anything involving infants.  Very understandable but I don’t want to wait until I am gone, for some advances to be made.  All Ataxia and movement disorder patients need more awareness!  That is why I started this website and why I will continue to advance this platform. 

Conclusion

Ataxia SCA 15 is a rare and debilitating neurological disorder that affects coordination and balance.  While there is currently no cure for this condition, ongoing research offers hope for the development of treatments that can improve the quality of life for individuals living with SCA 15.  In the meantime, early diagnosis and symptom management remain crucial in helping those of us affected by this condition.
