Reading the posts in the thread I think it is time to talk based on my 14 years of experience with PD. Yes PD shows the following symptoms: Saliva production increases, face muscles including tongue and throat get weaker like all the other muscles, they also become stiff and the brain may have difficulties in retrieving the words. Results are drooling, swallowing difficulties, weaker voice, masked face and slowness in expressing yourself. Are there any solutions? Yes there are remedies. Firstly get speech therapy from a specialist in this field. Generally speech therapy is used for children so find an expert who is working on neurological diseases. Not easy to find but you have all the time to search for the right specialist. He/she will teach you how to workout your weakened muscles and how to make your voice heard. Keep in mind one point you have to work on it regularly every day. As to the memory side keep your mind working by regular exercises like mental calculation, solving puzzles like sudoku, etc. Your homework is to keep up the spirit. I hope this helps.
