Database: Prevalence of gastrointestinal symptoms, severity of dysphagia, and their correlation with severity of amyotrophic lateral sclerosis in a Mexican cohort

This database was generated with the help of 43 Mexican patients diagnosed with amyotrophic lateral sclerosis (ALS). The presence and severity of gastrointestinal (GI) symptoms and dysphagia were identified by means of the Gastrointestinal Symptom Rating Scale (GSRS) and the Functional Outcome Swallowing Scale (FOSS). The Revised ALS Functional Rating Scale (ALSFRS-R) was utilized to determine the severity of ALS. ALSFRS-R scores were divided into two categories: those with mild to moderate ALS (≥40-30 points) and patients with moderate to advanced ALS (29-≤20 points).
