Hello. My mother was diagnosed about six years ago. She is living in a senior living center, in independent living. She is walking pretty well, the Sinemet has helped that tremendously. Her talking and swallowing are getting more difficult. And yes, her dementia is really affecting her memory. We have the nurses at her facility put together her medications daily and bring them up to her every morning. She takes Sinemet 3 times a day, and they label the pill box accordingly. that has helped tremendously. In terms of her personality...she is more paranoid, and the filter between her brain and her mouth is definitely not there anymore, lol! She gets very frustrated, as she is aware of her memory problems. The isolation caused by COVID-19 has not helped with her mental well-being. We really need nice weather so she can get outside.
