Clinical diagnosis and management of spinocerebellar ataxia in a resource-constrained setting: a case report from Eastern Nepal.

INTRODUCTION

Spinocerebellar ataxias (SCA) are a diverse group of neurodegenerative disorders with autosomal dominant inheritance, primarily affecting the cerebellum and its connections. Diagnosis typically involves genetic testing, but in resource-limited settings, clinical and neuroimaging assessments become critical. This case report highlights the role of nongenetic methods in diagnosing SCA and outlines management strategies in such settings.

CASE PRESENTATION

A 41-year-old male presented with a 2-year history of progressive gait imbalance, headache, and abnormal speech. He had a family history of similar symptoms in two siblings, but no significant past medical history. Clinical examination revealed scanning speech, dysmetria, and a broad-based gait. Clinical and neuroimaging findings, including cerebellar atrophy, led to a diagnosis of SCA in the absence of genetic testing. Patient management with speech, occupational, and physical therapies, showed gradual improvement.

DISCUSSION

SCA, characterized by cerebellar atrophy and a range of clinical symptoms, is typically diagnosed through genetic testing, but clinical and imaging assessments are crucial when genetic resources are limited. This case illustrates that a comprehensive clinical evaluation, including neuroimaging, can support the diagnosis of SCA even without genetic testing. Strategic management emphasizing symptomatic relief and functional improvement through a multidisciplinary approach, including regular follow-up and personalized therapy, are crucial, as evidenced by the timely improvement observed in our case.

CONCLUSION

In resource-limited settings, a comprehensive clinical and neuroimaging assessment is essential for diagnosing spinocerebellar ataxia when genetic testing is not feasible. Effective management through multidisciplinary therapies can improve patient outcomes, underscoring the need for innovative strategies to enhance diagnostic and treatment capabilities in such environments.
