This early-phase pilot study will test whether a nasal spray containing exosomes from human dental stem cells is safe and feasible for people with treatment-resistant schizophrenia who have persistent negative symptoms like social withdrawal and lack of emotion. Fifteen long-term…

This study tests whether aerobic exercise, alone or with a gentle brain stimulation technique called tDCS, can improve thinking and memory in people with treatment-resistant schizophrenia. About 160 participants will be assigned to exercise, tDCS plus exercise, or a control group…

This study tests whether a type of talk therapy called narrative exposure therapy (NET) is practical and helpful for people with psychosis who have experienced trauma. One participant will receive NET sessions and complete questionnaires about their symptoms and experiences. The …

This study aims to see if peer support can help pregnant and postpartum veterans who have serious mental illness. Researchers will develop a program where trained peer specialists offer support, then test it with 24 veterans to see if it is helpful and practical. The goal is to i…

Researchers at King's College London are studying what happens in the brain when people hear voices or sounds others cannot hear, known as auditory hallucinations. The study compares people with schizophrenia, schizoaffective disorder, or related psychotic conditions to people wi…
