Brief Summary:
This study aims at investigating the neuroplastic potential and the possible factors affecting rehabilitation in chronic schizophrenia patients on stable medication, by investigating the cumulative pattern of serum BDNF representing the neuroplasticity in the brain, through quantitative stimulus such as rTMS.

Condition or disease Intervention/treatment Phase
Schizophrenia Device: CR Technology, TAMAS for repetitive TMS Not Applicable

Detailed Description:
Subjects who have been enrolled for this study will take baseline evaluation for sociodemographic data and serum level of BDNF, plasma Prolaction, and magnesium, etc. And then, weekday regular stimulation through rTMS will be applied on DLPFC of brain. After the completion of stimulation for 2 weeks, the change or response of serum BDNF will be analyzed and compared.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 21 participants
Intervention Model: Single Group Assignment
