Choking/ swallowing difficulties.....dysphagia

Hello everyone, Does anyone on here or carers caring for patients suffer from choking/swallowing difficulties....dysphagia? I was talking to a lady the other night on the MJF for Parkinson's and she was telling me a sad story about her husband  who died from choking on his pills as he suffered from this through having Parkinson's and before that he always choked whilst eating? Im doing researchon this and would be very grateful for anyones stories or help :-)
