Parkinson’s Disease Psychosis (PDP) is diagnosed in patients with Parkinson’s Disease (PD) who experience hallucinations, delusions, and/or minor illusions, among other specific criteria. Psychotic symptoms may affect anywhere from 30% to 60% of PD patients sometime during their disease progression and substantially decrease quality of life. Oftentimes these symptoms are underreported by PD patients, possibly due to embarrassment or not realizing the connection between these symptoms and their disease state. This study examines the rate of reporting psychosis symptoms in response to a targeted PDP questionnaire compared to rates of reporting symptoms to healthcare providers.
The Western Institutional Review Board approved this single-center, cross-sectional observational study. Subjects (N=104) were identified from within the patient population at an outpatient clinic by screening medical charts for eligibility. Inclusion criteria focused on PD patients and/or caregivers who had verbally consented to take the PDP questionnaire at their upcoming provider visit and had attended at least one provider visit for treatment or assessment of PD before introduction of the questionnaire. Those who did not consent or only partially completed the PDP questionnaire were excluded. The questionnaire was developed with input from movement disorder and neuropsychiatric physicians at Dent Neurologic Institute. It was completed by patient or caregiver and included 4 items (for patient) or 2 items (for caregiver) probing for symptoms of hallucinations, illusions, or delusions.
Results of the survey were recorded and stored in patients’ medical chart and study records. Demographic data as well as current PD and PDP treatments, presence or absence of PDP symptoms as noted in the patient’s chart, and questionnaire responses were collected and analyzed. The frequency of disclosure of PDP symptoms in response to a targeted questionnaire was compared to frequency of reporting symptoms to a healthcare provider during the course of normal clinical practice. A McNemar’s test for symmetry will be used to determine if the questionnaire triggers additional reporting of symptoms.
