as for word finding difficulties i look at pd as a condition that affects the ram on a computer. the basal ganglia initiate motor and thinking circuitry. your memory is fine but the circuit that gets the word to speech is a little slow. when you get in a hurry or you have a number of simultaneous tasks it gets worse. you may consider 2 approaches: slow down and concentrate on one thing at a time or perhaps discuss increasing your pd treatment with your doctor.
are there any tricks to remembering words when you have parkinson's disease?
