Brief Summary
The main purpose of this study is to determine whether intensive repetitive transcranial magnetic stimulation (I-rTMS) is effective in the treatment of negative symptoms in schizophrenia patients and whether it has a positive influence on their cognitive functions, social functions, quality of life, alpha frequency and cortical silent period changes. Also, this study should provide data about safety and tolerability this I-rTMS treatment in schizophrenia patients.

Interventions
16 sessions/4 days (4 sessions per day), 2000 stimuli per one session, 20 trains per session (train interval= 10 sec., intertrain interval= 30sec.), stimulation intensity 110 % related to the individual resting motor threshold; in total 32,000 stimuli, 20 min. pause is between every stimulation session for safety reasons.v

Eligibility Criteria
You may qualify if:
- Signed an informed consent, the patient must be able and willing to participate in a research study,
- Undergo an examination by international neuropsychiatric questionnaire MINI - PLUS to confirm the diagnosis of schizophrenia
- schizophrenic illness duration longer than one year,
- have a stable and consistent drug treatment at least two weeks prior the rTMS treatment
- persistent negative symptoms without further psychiatric comorbidity (like depression, mania, anxiety disorders, personality disorders, etc.) in the foreground of the illness
- The sum of negative scores in the range Positive and negative symptom score (PANSS) must be 20 points or higher and at least one item from the area of negative symptoms (N1-N7) must be ≥ 4 points (at least moderate, clinically significant symptoms),
- improvement in negative symptom-sum (measuring by PANSS) must be 10% or lower during the last two weeks before rTMS stimulation.
You may not qualify if:
- involuntary stay in a psychiatric clinic during the recruitment of patients;
- clinically relevant unstable medical conditions;
- factors incompatible with the use of rTMS, such as pacemakers, heart pumps and other metal implants;
- history of epileptic seizures or the presence of epileptic activity documented on the basis of EEG
- current treatment with anticonvulsant acting drugs such as anticonvulsants, benzodiazepines (10mg/D or less of diazepam or equivalent dosage of other benzodiazepines);
- lack of cognitive skills for participation;
- clinically relevant psychiatric comorbidity (any other axis 1 diagnosis) detected using MINI Plus, including the current abuse of drugs and alcohol;
- heart attack or traumatic head injury in the anamnesis
- Patient unable to undergo a brain MRI
- Acute risk of suicide;
- knowledge of Czech language at a level that does not allow fill the required test battery;
- pregnancy
