Why carry out this expert panel?
|
Psychosis, with symptoms such as hallucinations and delusions, is a common and debilitating feature of Parkinson’s disease. |
The current lack of simple and standardized criteria for the screening of psychosis in Parkinson’s disease limits the identification of patients who need treatment. |
We present the findings and guidance developed from consensus meetings with a group of experts on psychosis in neurodegenerative disorders. |
What was learned from the expert panel?
|
Untreated symptoms of psychosis in Parkinson’s disease are associated with poor outcomes, poor quality of life, and significant distress to the caregiver and patient. |
The proposed screening tool and treatment algorithm may provide guidance for improved management of Parkinson’s disease psychosis. |
