My father is 97-years-old with Parkinson’s how do I know if he need s more medication?

Thank you naheaton. Took him to the urologist and actually his protate was okay and residual urine only 140 cc as it should be normally less than 100 cc so no med was given there. Finally heard from the neurologist and he put dad on klonopin 0.5 mg at night, so we will try this tonight and hope all will get a good nights sleep. Unfortunately, urinary frequency and urgency is part of Parkinsons, so we have doubled his pullup for tonight and will change it when we wake up if needed.

I don't know about Parkinsons, but if he's not emptying his bladder fully because of an enlarged prostate for instance, that might explain the bathroom visits constantly. Just a thought.
