Figure 1.

DRT medication history in the PDP+ group. The timing of dopamine agonists (green bars), levodopa (blue bars), or combined medication (red bars) is shown with respect to the onset of hallucinations (‐ years = prior to PDP onset). Patients have been categorized into subgroups based on DRT regime at time of hallucination onset: agonist = only dopamine agonist exposure, combined = both dopamine agonist and levodopa exposure, L‐Dopa = only levodopa exposure, Misc = complex DRT exposure, none = not on DRT. DOPAG, dopamine agonist; DRT, dopamine replacement therapy; LDOPA, levodopa; PDP, Parkinson's disease psychosis.
