Experimenteel: Safety of rTMS in schizophrenia patients
Participants will receive repetitive transcranial magnetic stimulation via MagPro x100 device to the vermis of cerebellum twice a day over 5 days
|
Participants will receive 10 repetitive transcranial magnetic stimulation sessions to the vermis of cerebellum using the MagPro x100 TMS device. These 10 rTMS sessions will be administered from Monday to Friday in five days, twice a day with a minimum of 4-hour gap between the sessions. Repetitive TMS will be applied with the intermittent theta burst pattern (iTBS). These parameters are known to cause excitation in brain activity. Anatomically precise localization of rTMS will be achieved using a frameless stereotactic system. |

Positive and Negative Syndrome Scale (PANSS) - Positive Subscale
Tijdsspanne: Baseline, 5 days (post-treatment), 1 week post treatment
|
Potential therapeutic efficacy was evaluated with the Positive and Negative Syndrome Scale (PANSS) Positive Subscale, a 7 item subscale measuring the presence/absence and severity of positive symptoms of schizophrenia.
The minimum score is 7 and the maximum score is 49, with higher values representing greater symptom severity.
Therapeutic efficacy was assessed at baseline, after 5 days of treatment, and 1 week post treatment.
The overall PANSS total score (minimum = 30, maximum = 210) is computed by summing the positive, negative, and general subscales; and higher values represent more severe schizophrenia psychopathology.

Positive and Negative Syndrome Scale (PANSS) - General Subscale
Tijdsspanne: Baseline, 5 days (post-treatment), 1 week post treatment
|
Potential therapeutic efficacy was evaluated with the Positive and Negative Syndrome Scale (PANSS) General Subscale, a 16 item subscale measuring the presence/absence and severity of general psychopathology of schizophrenia.
The minimum score is 16 and the maximum score is 112, with higher values representing greater psychopathology severity.
Therapeutic efficacy was assessed at baseline, after 5 days of treatment, and 1 week post treatment.
The overall PANSS total score (minimum = 30, maximum = 210) is computed by summing the positive, negative, and general subscales; and higher values represent more severe schizophrenia psychopathology.
