I was diagnosed in 1996 at the age of 48, I am now 62. I have been through just about every symptom that exists with PD. I have even had 3 doctors tell me I had no symtoms and wondered if I was misdiagnosed. After putting me through some dexterity tests the symptoms reappeared.
I now have difficulty with freezing while walking and rigidity in my facial expressions. Yes, symptoms come and go. I just try to stay active. I am able to do about anything I want, it just takes a little longer. PD has taught me patience, something I was lacking before.
Good luck to you.
