My husband has Parkinson's (for about 10 years now). Recently, he has terrible coughing spells even when he is not eating. It is not so much a cough as a type of almost chocking even when he is not eating. He is on thickened liquids (because he had a small stroke last November) and he is on a soft diet. However, his coughing is not just limited to when he is eating. The fear is that he might asperate. His speech has also been affected. What is causing the coughing spells? He has been working with a speech therapist who has taught him how to swallow but this cough occurs even when he is not eating.
