Condition
Schizophrenia
Intervention
Functional Magnetic Resonance Imaging (MRI) will be applied to investigate brain functions of 60 patients with schizophrenia, 30 of whom will undergo cognitive behaviour therapy. All patients will be scanned twice, 8 to 9 months apart, during a series of tasks known or likely to be sensitive to symptoms of schizophrenia.
Control data will also be obtained from 20 patients with schizophrenia who have shown a good response to their antipsychotic medication and 20 healthy subjects.
