Hi Alza150;
I am 46yo, i was diagnosed last year with PD. Before my diagnosis, i sensed i was forgetting matters at work and some at home. I found myself using more and more reminders on my computer screen and i kept a rough hard copy diary to carry with me, as well as a chalk board at home. Since then and beyond my diagnosis i still use my chalk board to remind me of various items that need my attention, it also doubles as a place funny comments can be added by friends and family, something i encourage.
