Scientific title | A randomised, repeated measures investigation of rhythmic auditory cues as a potential intervention for attentional fluctuations in dementia with Lewy bodies (DLB)/Parkinson's disease dementia (PDD) |
Study acronym | PECFC |
Study objectives | Dementia with Lewy bodies (DLB) accounts for 15% - 20% of late onset dementia whilst Parkinson's disease occurs in 1% of individuals over the age of 65; with at least 50% of these individuals developing symptoms of dementia (Parkinson's disease dementia - PDD). In addition to memory problems, people with these conditions experience persistent hallucinations, parkinsonian symptoms, marked problems with attention and fluctuating consciousness. Other symptoms that occur commonly include repeated falls, faints, temporary loss of consciousness, delusions and Rapid Eye Movement (REM) sleep behaviour disorder. Rhythmic auditory cues can regulate attentional processes and fluctuating cognition in patients suffering from DLB or Parkinson's Disease Dementia (PDD) as reflected by a decrease in reaction time standard deviation variability in attentional tasks. |
Ethics approval(s) | South London and Maudsley NHS trust approved of protocol on 22 November 2005 (ref. no.: 05/Q0706/264). |
Health condition(s) or problem(s) studied | Dementia |
Intervention | Baseline versus rhythmic auditory cue versus rhythmic auditory cue at increased volume - a one-off assessment comparing patients baseline performance with performance under different experimental conditions. |
Intervention type | Other |
Primary outcome measure | Reaction time standard deviation, measured at intervention. |
Secondary outcome measures | Measured at intervention: 1. Attentional performance 2. Reaction time 3. Tapping speed 4. Tracking precision 5. Electroencephalogram (EEG) mean frequency variability 6. Frequency of occurrence of stimulus independent thoughts |
