Impact of ataxia aetiology on self-reported mental health, fatigue, cognition and ataxia symptom severity

Abstract

Introduction: it has been increasingly recognised that the impact of Ataxia extends beyond physical and motor symptomology. However, it is less known whether self-reported non-motor and ataxia symptom severity varies across ataxias of differing aetiology, which would have important implications for providing more targeted treatment.

Aim: this study aimed to investigate the impact of ataxia aetiology (hereditary, acquired or idiopathic) on self-reported depression, anxiety, fatigue, cognitive deficits, and ataxia symptom severity. Comparisons were also made between the ataxia sample as a whole and a neurologically healthy control group.

Method: responses were collected using a cross-sectional online survey to recruit a national UK sample of people with ataxia.

Results: the study recruited 110 participants with ataxia (hereditary = 51, acquired = 16, idiopathic = 43) and 32 healthy controls. No significant differences were found across study variables for different causes of ataxia. However, participants with ataxia did report significantly higher levels of depression, anxiety, fatigue, cognitive deficits, and ataxia symptom severity compared to healthy controls.

Conclusion: this study found that participants with ataxia self-reported increased non-motor symptoms compared to healthy controls, which was a generally homogenous experience across different causes of ataxia. There was also considerable comorbidity of symptoms which requires further exploration. This study highlights the need for early assessment and intervention to address these non-motor symptoms in ataxia populations.
