Dream structure in Parkinson's patients.
The Journal of Nervous and Mental Disease August 1, 1992 C Cipolli, R Bolzani, R Massetani et al.
Dream recall frequency in people with Parkinson's disease is comparable to that of other older adults, but the length and narrative coherence of their dreams vary with their cognitive and language abilities. Fifteen outpatients with idiopathic Parkinson's disease, all treated with L-dopa and without psychiatric symptoms, were awakened from REM sleep to report dreams. Thirteen provided at least one dream, yielding a 71.4% recall rate. Longer and more story-like dream reports were associated with higher cognitive functioning and, partly, better language comprehension, but not with age, illness duration, or L-dopa dose.
