|Official Title:||Impact of Transcranial Slow Oscillating Stimulation on Memory Consolidation During Slow Wave Sleep of a Daytime Nap in Patients With Mild Cognitive Impairment(MCI)|
|Study Start Date :||April 2013|
|Actual Primary Completion Date :||August 2016|
|Estimated Study Completion Date :||December 2017|
Experimental: 0,75 Hz stimulation
transcranial slow oscilliating stimulation (tSOS)during periods of SWS
Device: 0,75 Hz stimulation
Other Name: oscillating direct current brain stimulation
Sham Comparator: SHAM stimulation
SHAM stimulation during periods of SWS
Device: SHAM stimulation
- Retention of declarative memories after 0.75 Hz stimulation during SWS, vs after sham stimulation during SWS [ Time Frame: 4 Weeks ]Retention between stimulation conditions (0.75 Hz during SWS, vs sham stimulation during SWS) in the declarative memory task.
- Amount of Slow wave Sleep, spindels, eeg-correlates, further memory systems [ Time Frame: 4 Weeks ]
- Amount of slow wave sleep assessed by standard polysomnographic criteria in 0,75 Hz vs SHAM stimulation during SWS.
- Spindel activity during sleep indicated via several spindel parameters like number, duration, frequency of spindles; compared between 0,75 Hz and SHAM stimulation during SWS.
- Neuronal correlates (EEG-power in slow oscillation frequency bands induced by 0,75 Hz vs SHAM stimulation during SWS; EEG-correlates of encoding and retrieval of a declarative memory task).
- Performance in further memory systems (procedural), compared between 0,75 Hz and SHAM stimulation during SWS.
