tDCS(Transcranial Direct Current Stimulation) Efficacy in Bipolar Depression : RCT Study

Augmentative Transcranial Direct Current Stimulation (tDCS) in Patients With Bipolar Depression: RCT, IIT Study.

The purpose of this study is to determine whether transcranial direct current stimulation (tDCS) is effective and safe in the treatment Bipolar depression.

Randomized, double-blind Controlled Clinical Trial. Subjects Adults (between 19 and 65 years of age) with Bipolar depression who meet the inclusion criteria and who agree to participate in the study Will recruit from clinical referrals.

• Active tDCS Anode - left DLPFC Cathode - right DLPFC Electric current is 2mA - Current is applied for 30 min
• Sham tDCS Same assembly is used Current is applied for 1 min

Both groups 30~42 stimulation sessions on consecutive days.

Baseline(visit 1), 2 week(visit 2), 4 week(visit 3), 6 week(visit 4), and 12 week(visit 5) Check compliance with mobile application(MINDD-CONNECT) connections.

Assessment:

Depression rating scale: HAM-D(Hamiltion Depresiion Rating Scale), HAM-A(Hamilton Anxiety Rating Scale) Maniac rating scale: YMRS(Young Mania rating scale) CGI-BP(Clinical Global Impression-Bipolar) Q-LES-Q-SF(Quality of Life Enjoyment and Satisfaction Short form) Q-LES-Q-Q(Quality of Life Enjoyment and Satisfaction Questionnaire) qEEG(Quantitative Electroencephalography)

Check compliance with mobile application(MINDD-CONNECT) connections.

Inclusion Criteria:

• A person who is determined to be excluded for using tDCS medical device for other reason (e.g. metal plate is inserted on head, etc.)

• A person who is determined to have problems with scalp deformation, inflammatory response or brain wave and attachment of direct current because of other dermatological problem

• A woman who disagree with medically allowed contraception* until 24 weeks after the application of investigational device among woman subject who is possible to get pregnant

  * Medically allowed contraception: condom, oral contraception for at least 3 month, injection or insert contraception, Intrauterine Device, etc.
