An animal model of oral dysphagia in amyotrophic lateral sclerosis.

Relatively little is known about the underlying neuropathology of dysphagia in amyotrophic lateral sclerosis (ALS); thus, effective treatments remain elusive. Tremendous progress toward understanding and treating dysphagia in ALS may be possible through the use of an animal model of dysphagia in ALS research; however, no such animal model currently exists. The most logical candidate to consider is the SOD1-G93A transgenic mouse, the most widely investigated animal model of ALS.
