Thanks for the great posts by you and @wanieta. My 75 yr old husband, Vietnam veteran/Agent Orange exposure is diagnosed with Parkinsonism associated with Posterior Cortical atrophy (PCA) and Corticobasal syndrome (CBD). He lost reading abilities 2-3 years ago with memory decline, followed by left side weakness and an almost lifeless arm. He can no longer enjoy daily dog walking, has had a few falls but is riding Air-dyne bike here for strength. Neurologist increased Donepezil from 10 mg to 20 mg recently. Movement disorder neuro agreed he could try Carbidopa Levodopa, started with half pill. This has reduced aching and icy cold feeling in his arm but not much change to arm and leg mobility or balance. I found good Neuro PT who used a bit of boxing in the routine ! It has been a journey to advocate and find best care for him. Frustrating that Doctors say there are no supplements, or alternative therapies. His daily Statins have not been questioned by Doctors at all. He has been very healthy eater for years with exception of nightly ice cream treat. Clinical trials ?…I wish I could find one ! Asking what is an integrative physician. Every day I wonder what more can I do. Thanks and strength to all
