A pretty good indicator is loss of sense of smell. The only symptoms I really had were REM sleep, loss of smell, and something that has gotten much more intense noww that I have been diagnossed with "idiopathic PD" - Which means there are few strong indicators of PD (No tremors but there are enough other signs that suggest that the patient DOES have PD

PT HAS THESE SYMPTOMS THAT SUGGEST PD OR CONSISTENT WITH, PD
'
t has these Symptoms that suggest PD
REM Sleep Disorder
Lack of sense of smell
Strong response to L-dopaExaggerated startle respoinse

Excessive Startrle response (much like babies have when their entire body responds to a loud or frequent sound unexpedted sound
exaggerated response *full body response" to any unexpected sound
PT gets 'lost' in tasks that require lots of attention (takes 3 hours to fill pill boxes

PT doesn't have these symptoms that you would expect to see in a PT with PD
Tremors

AMBIGUOUS SYMPTOMS
Frequest Falls (only falls once a year)
Can get disoriented in space and time
Double vision. If patient has a wandering eye as a child, he may have it return once he develops PS. Because , at birth, the brrain coiuldn't control the teye muscles to both focus on the same thing
Older -brain has to work harder to retain single vision.Muscles need l-dopa to send the bfain's orders for the eyes to work together.

Other Symptoms you would expect a person with PS to display that this patient doesn't have
REM Sleep Disorder
Loss of sense of Smell
