Dysphagia in Friedreich Ataxia

Area of Science:

• Neurology
• Gastroenterology
• Speech and Language Pathology

Background:

• Friedreich ataxia (FRDA) is a rare inherited neurodegenerative disorder.
• Dysphagia is a common but often underdiagnosed complication of FRDA.
• The impact of dysphagia on quality of life in FRDA requires further investigation.

Purpose of the Study:

• To characterize oropharyngeal dysphagia in FRDA.
• To identify predictors of swallowing penetration and aspiration.
• To assess the psychosocial impact of dysphagia in FRDA patients.

Main Methods:

• Sixty FRDA participants underwent screening using the Swallowing Quality of Life questionnaire (Swal-QOL).
• Dysphagia assessments included the Frenchay Dysarthria Assessment (FDA-2) and videofluoroscopic swallowing study (VFSS).
• Correlation with disease parameters (age, duration, FARS, GAA repeats) and logistic regression for aspiration predictors.

Main Results:

• 98% of participants reported dysphagia; 34.2% showed significant airway compromise (PAS>3).
• Silent aspiration occurred in 26.3% of participants, without overt symptoms.
• Dysphagia severity correlated significantly with disease duration and severity (FARS).

Conclusions:

• Oropharyngeal dysphagia is highly prevalent in FRDA and progresses with the disease.
• Silent aspiration is a significant risk in FRDA, requiring regular instrumental evaluation.
• Dysphagia substantially impacts the quality of life for individuals with FRDA.
