I'm taking my 92 year-old dad to his neurologist today. Last time the neurologist had told me that my dad's flavor of Parkinsonism might be PSP-- I think because my dad can't look up. I will ask if PSP can be confirmed. Is there anything new in medication or treatment I should ask about? He's already on Carbidopa-Levodopa and newly on Amantadine which has really helped. He's wheelchair bound with legs virtually permanently crossed. He can still eat regular food--tends to choke when taking a pill with water, though we usually grind up pills and give in applesauce. He is unable to say what he means much of the time and speaks so softly that it's hard to hear him. Any suggestions for questions for the doctor?
