Trial Outcomes & Findings for The Effect of rTMS Treatment on Alzheimer's and Sleep Quality (NCT NCT01894620)

Results Overview

We anticipate to see a cognitive improvement as measured by the Montreal Cognitive Assessment (MoCA) after two weeks of applying rTMS. This assessment tool gives a score from 0 to 30 points, with higher scores representing better cognitive ability.

Measure	rTMS Real-sham rTMS real-sham and rTMS sham-real interventions. Each patient will receive both real and sham treatment in two different blocks of time. The assessments after the sham treatment will serve as placebo effect compared to those after real treatment. rTMS real-sham: In this intervention patients receive 4 weeks of rTMS treatment with real coil and then 4 weeks of treatment with sham coil; there will be 4 weeks of break between the two blocks of treatment. rTMS sham-real: In this intervention patients receive 4 weeks of rTMS treatment with sham coil and then 4 weeks of treatment with real coil; there will be 4 weeks of break between the two blocks of treatment.	rTMS Sham-real rTMS real-sham and rTMS sham-real interventions. Each patient will receive both real and sham treatment in two different blocks of time. The assessments after the sham treatment will serve as placebo effect compared to those after real treatment. rTMS real-sham: In this intervention patients receive 4 weeks of rTMS treatment with real coil and then 4 weeks of treatment with sham coil; there will be 4 weeks of break between the two blocks of treatment. rTMS sham-real: In this intervention patients receive 4 weeks of rTMS treatment with sham coil and then 4 weeks of treatment with real coil; there will be 4 weeks of break between the two blocks of treatment.

PRIMARY outcome

Timeframe: Change between baseline and 2 weeks after the start of treatment

Population: Results are divided into the two treatment type groups (real vs. sham).

We anticipate to see a cognitive improvement as measured by the Montreal Cognitive Assessment (MoCA) after two weeks of applying rTMS. This assessment tool gives a score from 0 to 30 points, with higher scores representing better cognitive ability.

Cognitive Improvement Measured Using Montreal Cognitive Assessment (MoCA)	-0.667 MOCA score change at 2 weeks Standard Error 1.116	1.8 MOCA score change at 2 weeks Standard Error 0.633

SECONDARY outcome

Timeframe: After four weeks after the start of treatment

Population: Note that this aspect of the study was not performed. Therefore, no data is available.

We anticipate to see an improvement on the sleep quality of the patients (assessed by EEG waves during sleep) after 4 weeks of rTMS treatment.
