My 80-year old father has become very slow and unsteady on his feet - 'they feel spongy', a bit confused with poor short term recall and has an occasional tremor in one hand. Up until quite recently he had been on flecainide acetate for over ten years because of atrial fibrillation. For at least the last 40 years he has been a depressed, inactive, sedentary person. The doctor recently agreed with him that he had Parkinson's Disease and he also came off FA and had a pacemaker fitted on the advice of a cardiac doctor. He is on a low dose of Sinamet (for the PD symptoms) and has never displayed symptoms such as freezing, nightmares or a mask-like face. His PD-type symptoms are certainly not getting any worse since starting this new therapy and I think he is getting better, although he doesn't agree - 'it's a progressive condition'. I can't help thinking his impairments might have been caused/exacerbated by the FA, but he refuses to countenance this suggestion.
