Hi Colinr - some people are diagnosed with PD at a young age, then others at various ages. Some cope quite well with controlled medication without problems, but we are not all same, it all depends on how your body reacts to PD. Glad you found some one to talk to and perhaps give or get advice from in return. I was DX when I was 57 and I’ve had it for 8 years now.
Hope you are coping well - Sheila
