Not Applicable
Active, not recruiting
Conditions
Schizophrenia
Interventions
Device: iTBS
Device: Shame stimulation
Registration Number
NCT04714970
Lead Sponsor
Central South University
Brief Summary

The weight gain and metabolic dysfunction has been vital conditions for individuals with schizophrenia. rTMS is a promising novel intervention, which have strong potentials on moderating increased appetite and cognitive deficits in schizophrenia, as it has been proved for the treatment of depression.

Therefore, the investigators designed this randomized controlled clinical trial to evaluate the efficacy and safety of rTMS, using iTBS pattern, on prevention and treatment for elevated appetite and cognitive deficiency in individual with schizophrenia.

Detailed Description

The weight gain and metabolic dysfunction has been vital conditions for individuals with schizophrenia. The cognitive function deficit has also been a major symptom for schizophrenia. However, metabolic dysfunction could further impair the cognition. rTMS is a promising novel intervention, which have strong potentials on moderating increased appetite and cognitive deficits in schizophrenia, as it has been proved for the treatment of depression.

Therefore, the investigators designed this randomized controlled clinical trial to evaluate the efficacy and safety of rTMS, using iTBS pattern, on prevention of the elevated appetite and cognitive deficiency in individual with schizophrenia. The intervention will last for 5 continuous days and the follow-ups are scheduled at baseline, 6days and 36days. The primary outcomes include the change of MCCB score, TFEQ score and EEG data. Secondary outcomes include the change of serum metabolic indexes and anthropometry indexes.
