Experimental group received 20 minutes of frequent Transcranial Magnetic Stimulation (rTMS) as daily 20 minutes of 1 Hertz in Dorsolateral Prefrontal Cortex of right hemisphere and stimulatory Teta breast in Dorsolateral Prefrontal Cortex of left hemisphere. Multivariate Covariance (Mancova) was used for analyzing data.Results : Results showed that frequent Transcranial Magnetic Stimulation (rTMS) is useful for improving cognitive and emotional flexibility of patients with Bipolar II Disorder.Conclusion : After medical interference, there were some meaningful changes about cognitive and emotional flexibility and improvement of Bipolar II Disorder between experimental and control groups.
