Swallowing problems (also known as dysphagia), can include coughing while eating or drinking, aspiration (not being able to cough up food or liquid that went the wrong way), gag reflex, etc. Difficulty swallowing can occur as Alzheimer's disease or related dementias progress due to the fact that dysphagia can result from brain damage caused by the degenerative process or entirely different issues, such as a stroke, illness, or other complications. If there are concerns that dysphagia might occur, it is a good idea to consult with a physician and/or speech therapist, where a video x-ray known as a videofluoroscopy can be performed to evaluate the pathways of food and liquid when it is swallowed. A speech therapist can also offer recommendations on how to change ones diet, improve swallowing, and promote safe eating.
