Hi, my name is Angela. I am a graduate student in speech language pathology and am concerned about my father, I think he may have PD. My father has hand tremors, has been severely depressed for the past year (has had depression for at least past 5 years) and is taking medication for the depression and to help him to sleep. Also, I had used my father as a subject to practice doing an oral motor exam, (tests strength, etc. of the oral musculature) and he has weakness in his tongue and can't keep intraoral pressure in. I might be totally wrong but was wondering what are the symptoms everyone had that made you realize that you needed to see a neurologist. I have mentioned my feelings to my father but he states it's nervousness. Can anyone help? Thanks!
