Thanks to Dr Okun for sharing these tips
Tips:
Here are few tips Dr Okun shares w/ people in his practice and a few up to date articles/information:
1- review the medication list
2- consider simplifying medications for Parkinson's (sometimes to levodopa only).
3- consider lower doses of Parkinson's medications administered more frequently.
4- check for a urinary track infection.
5- sleep is really important; consider a sleep tracking wearable device and get the total hours of sleep a night to 6-8 hours (if possible).
6- Quetiapine helps more with sleep than with psychosis.
7- Cholinesterase inhibitors help some folks.
8- The safest medications for psychosis once you have considered 1-7 are pimavanserin and clozapine as they, in general, will not worsen the Parkinson's symptoms like other anti-psychotics.
9- Clozapine in the US requires weekly blood monitoring and registration w/ the REMS registry (the Risk Evaluation and Mitigation Strategy program).
