Objectives: There has been limited exploration into the nature and development of psychotic experiences (PEs) in Parkinson's disease (PD). We aimed to comprehensively assess the frequency, severity, and associated distress of paranoia and unusual sensory experiences (USEs) in PD, and to assess what variables are significantly associated with these experiences, focussing on psychological processes central to understanding PEs in non-PD groups.
Method: A questionnaire battery was completed by 369 individuals with PD with a mean age of 66 years and mean time since diagnosis of 5 years.
The phenomenological differences in auditory hallucinations between schizophrenia and borderline personality disorder (BPD) are unclear in the existing literature, in part due to underpowered studies and heterogeneous research populations that do not represent those in the acute clinical setting. This study addresses this by using patient records to compare auditory hallucinations at the point of clinical psychiatric assessment for 341 unique patients, 165 with BPD and 176 with schizophrenia. Patients with BPD were found to have more subjectively distressing and objectively negative hallucinations, as well as more command hallucinations.

A brief imagery-based metacognitive intervention was developed to target the control mechanism of distressing mental images in psychosis.
