I read that dysphagia can be associated with certain kinds of dementia depending on what part of the brain is affected. No doubt stroke victims would be considered at risk and so as you intimate dysphagia is probably a red flag from the get go.
If dementia is correctly diagnosed then I can see dysphagia being a consideration. But it's the assumption that bothers me. And since dementia wasn't determined in my wife's case, you can then understand my frustration.
