            Maintenance ElectroConvulsive Therapy in Clozapine RESISTant Schizophrenia - the MECT-RESIST Trial

            Summary: Schizophrenia is one of the most severe and costliest mental disorders in terms of human suffering and societal expenditure. About 15-30% of patients do not respond to all known antipsychotics, including clozapine, the current gold-standard in these cases.

            A Study of the Safety and Tolerability of GA in the Treatment of Patients With Refractory Neuropathic Pain

            Summary: Previous studies have shown that the anterior cingulate cortex is involved in the regulation of pain and its associated negative emotions, that pyramidal neurons are highly excitable in chronic neuropathic pain conditions, and that silencing of pyramidal neurons can eliminate pain. The aim of this study was to evaluate the safety, tolerability, and efficacy of intracranial injection of GA (contain...

            Biomarkers in Clozapine-responding Schizophrenia

            Summary: The outline of the current project is to establish a cohort of patients with treatment refractory schizophrenia eligible for clozapine, to identify clinical and biological characteristics of clozapine responding patients. Patients will be offered treatment with clozapine according to national clinical guidelines. Before clozapine is initiated, patients will be offered a thoroughly neurobiological ...

            Accelerated Neuromodulation of Prefrontal Circuitry During Clozapine Treatment

            Summary: In this study, the investigators will examine whether a type of repetitive transcranial magnetic stimulation called accelerated intermittent theta burst stimulation (iTBS) can augment neurocognition in individuals who receive treatment with clozapine. Following a baseline evaluation and magnetic resonance imaging (MRI), participants will undergo a session of iTBS +MRI and session of sham delivery ...
