Hallucination and Parkinson's: Research papers
- Visual symptoms in Parkinson's disease and Parkinson's disease dementia
Results demonstrate that different hallucinatory experiences in PD do not necessarily share common disease predictors and may, therefore, be driven by different pathophysiological mechanisms.

- Psychiatric symptoms screening in the early stages of Parkinson's disease
The study found a high prevalence of psychiatric complaints in PD patients, mostly related to depression, anxiety, somatization and OCS. Hallucinations were also frequent, but not associated to cognitive function or dopaminergic doses, suggesting a different physiopathological background.

- Urinary 8-hydroxydeoxyguanosine correlate with hallucinations rather than motor symptoms in Parkinson's disease
The significant correlation between urinary 8-OHdG levels and hallucinations but not with dementia suggests that hallucinations are likely to have unique but unidentified mechanisms that lead to excessive production of 8-OHdG.

- Neuropsychological correlates of mild to severe hallucinations in Parkinson's disease
We aimed to explore the neuropsychological deficits associated with the different types of VH observed in PD, from minor hallucinations to well-formed VH with loss of insight. Prospective study of 57 PD patients with (n = 29) and without VH (n = 28) matched for age, education, antiparkinsonian medications, and disease duration

- Late-stage Parkinson's disease: the Barcelona and Lisbon cohort
Studies of late stages of Parkinson's disease (LS-PD) are limited. To provide an adequate health plan for patients in these most advanced stages, accurate information on their clinical condition is necessary.

- Serotonin 2A receptors and visual hallucinations in Parkinson disease
Complex visual hallucinations (VHs) occur in several pathologic conditions; however, the neural mechanisms underlying these symptoms remain unclear. Although dopamine may have a role, indirect evidence indicates that serotonin may also contribute to the pathogenesis of complex VHs, probably via involvement of the serotonin 2 receptor.
