Study Summary

Nuedexta is FDA approved for the treatment of pseudobulbar affect in ALS patients and anecdotal reports of improvements in speech, salivation or swallowing have been reported. However, no prospective study has been conducted to comprehensively examine and determine the physiologic impact of Nuedexta on both speech and swallowing physiology in a large group of ALS individuals. These data are needed in order to provide evidence-based guidance to the management of bulbar dysfunction in ALS.

Primary Outcome

The validated Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) will be performed on all collected videofluoroscopic swallowing studies to assess global swallowing function. The DIGEST total score is determined using the composite of individual airway safety and bolus efficiency subscores (range: 0-4). The DIGEST total is rated on a 5-point ordinal score ranging from 0 (no dysphagia) to 4 (life-threatening dysphagia).
