Description: Vivid dreaming is frequently present in patients with Parkinson’s disease. Neurologists often ask the patient whether he/she has vivid dreams or frequent nightmares. Partners of patients are frequently asked about: whether the patient suffers from vigorous movements during sleep, which could indicate REM-sleep Behavioral Disorder (RBD) which is often present in patients with Parkinson’s disease.

Here we only labeled TRUE when vivid dreams, or vivid dreaming is written down. We scored as TRUE: dreams; vivid dreams; vivid dreaming; lively dreaming; nightmares; reports of vigorous movements during sleep; everything that mentions a change in the dream or movement during sleep that are suddenly worth reporting. We did NOT score: REM-sleep Behavioral Disorder (RBD). These were scored in a separate section of the database. Explanation: Because we want to capture all the sentences that include something about dreams or nightmares, we decided to include all sentences with the word dream or nightmare. This might mean we do not only catch ‘vivid dreaming’, but together with the Clinical Diagnosis we can place the parameter into context.
