rTMS Add on Value for Amelioration of Negative Symptoms of Schizophrenia
Treatment of depression with repetitive transcranial magnetic stimulation (rTMS) has shown high evidence using high-frequency left dorsolateral prefrontal cortex (DLPFC) stimulation. The treatment of negative symptoms with the same protocol in schizophrenia is considered as possible effective. Theta burst stimulation is a new protocol which is characterized by shorter sessions showing first evidence that it's efficacy is comparable to the high-frequency rTMS. In this randomized placebo-controlled study the efficacy of high-frequency rTMS and TBS are evaluated.

Add-on MEmaNtine to Dopamine Modulation to Improve Negative Symptoms at First Psychosis
Antipsychotics affects the brain's dopamine system, and the drugs reduce delusions, hallucinations, and disorganized thinking, which are cardinal symptoms of psychotic disorders. However, negative symptoms e.g. anhedonia, avolition, and social withdrawal, as well as cognitive deficits, are not sufficiently treated. Memantine is used to treat Alzheimer's disease and affects the brain's glutamate system. AMEND is a 12-week, double-blind, placebo-controlled, randomized clinical trial (RCT) testing effects of add-on memantine to initial antipsychotic treatment in never-treated patients with first-episode psychosis. The main aim is to reduce negative symptoms. Secondary outcomes are cognition, psychotic symptoms, side effects. Glutamate levels in the brain will be measured before and after 12 weeks using an ultra-high field strength (7 Tesla) magnetic resonance scanner. AMEND will apply rational drug repurposing to optimize treatment of patients experiencing their first psychotic episode.

Goals in Focus: CBT for Motivational Negative Symptoms of Psychosis
This pilot feasibility trial aims to evaluate the "Goals in Focus" intervention for motivational negative symptoms in people with psychosis. Goals in Focus interventions translate findings of basic clinical research on psychological mechanisms of motivational negative symptoms into a tailored and comprehensive novel psychological treatment program. The current single-blind randomized-controlled study aims to test feasibility and to examine first estimates of the expected effect size of Goals in Focus to inform a subsequent fully-powered RCT. The feasibility data will be used to improve on the trial design and the provision of the "Goals in Focus" intervention where necessary.
