Clinical Trial Summary

Safety and performance study of the MemoWave electroencephalographic and sound recording device to increase slow brain waves during sleep to improve memory consolidation in subjects with mild cognitive impairment

Description:

24 subjects aged between 40 and 85 years, presenting a mild cognitive disorder of the amnesic type (ie a memory complaint, a Mini Mental State ≥ 24 and a score ≤26 on free recall or ≤45 / 48 on total recall of the RLRI16 test) will be included;

Each patient spends 3 polysomnography nights at hospital: 1 night of habituation without Memowave device and next 2 nights with Memovave.

The device emits sounds to increase slow brain waves but Memowave emits sounds during only one of the two nights of test (night placebo vs night "verum"). The attribution of the night is randomized.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	accuracy of Electroencephalography signals of Memowave	number of slow waves of Memomave divided by number of slow waves of Gold standard should be under 1	3 days
Secondary	Quality of the sleep	Score of 1 to 4 (where 4 is a good sleep and 1 a very bad sleep)	3 days
Secondary	efficiency on mnesic consolidation	memory grid .More the score is high, more the efficiency is better	3 days
Secondary	efficiency on mnesic consolidation	scale WAIS (Weschler Adult Intelligence scale). The score should be more than 100.	3 days
