CTenaLouise,
I only got formally dxd PD because I volunteered for a nerve function trial, although I'd known something was wrong with my left side for many yrs. I'll volunteer for any PD related trial I can get on to if I believe it will forward treatment - I don't believe there is a 'cure' as such.
Following another thread - my L side symptoms included frozen shoulder, elbow, knee & ankle all attributed to osteo arthritis. My heart is fine.
