- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: TRIPLE
- Phase: None
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~1. Participants who meets criteria of probable Alzheimer's disease defined by NINCDS-ADRDA research criteria.~2. Participants who meets criteria of depression in Alzheimers defined by NIMH criteria.~3. Participants who have been on fixed dose (including participants without any prescription) of antidepressants for at least two weeks on the screening visit.~4. Participants who have been on fixed dose (including participants not prescribed) of antidementia drugs (donepezil, rivastigmine, galantamine, and memantine) for at least for weeks on the screening visit.~5. Ambulatory participants with or without any aiding device~6. Participants who have one caregiver, who must live with the patient at least ten hours a week and must report the patient's behavior.~7. A study partner who can report how the participant is doing is needed.~8. Eligible family member must sign and give consent on behalf of participants, whereas participants can give assent.~Exclusion Criteria: Following potential participants will be excluded~1. In case their cognitive deficits are better explained by another disease (e.g., cerebral infarction, Parkinson disease, multiple sclerosis, normotensive hydrocephalus).~2. In case they have history of epilepsy~3. In case they need treatment by antipsychotics due to significant psychotic symptoms~4. In case they have urgent risk of suicide or severe depression and any doctor require their hospitalization to psychiatric units.~5. In case they have history of ineffectiveness with electroconvulsive therapy (ECT) or transcranial direct current stimulation (tDCS)~6. In case ECT or tDCS is clinically contraindicated~7. In case they are taking benzodiazepines or antiepileptic drugs on the screening visit~8. In case they scored less than ten on Mini Mental State Exam (MMSE) or scored 3 or more on Clinical Dementia Rating (CDR)~9. In case his/her GDS score is lower than 6 at baseline~10. In case he/she is unable to agree video recording on evaluation interview
