Body ownership is not impaired in schizophrenia. Schizophrenia patients often experience an altered sense of self, for example, as if someone else is controlling their actions. This impairment is described as a deficit in the “sense of agency”, and while it has been well established and linked to problems with sensorimotor brain signals, another category has been left unexplored: the “sense of body ownership” by which we feel that our bodies belong to ourselves. Using a full-body illusion experiment, EPFL scientists have now determined that body ownership is not affected in schizophrenia. Source 3n.
Schizophrenia, memory deficits: Solving the mystery behind a most stubborn symptom. Disruptions to the brain's internal GPS result in some of the severe memory deficits seen in schizophrenia. The new study in mouse models of the disorder marks the first time that schizophrenia's effects have been observed with such precision and clarity. The findings offer a promising entry point for attacking a near-universal and debilitating symptom of schizophrenia, memory deficits, which has thus far withstood all forms of treatment. Source 3h.
Schizophrenia disrupts the brain's entire communication system, researchers say. Some 40 years since CT scans first revealed abnormalities in the brains of schizophrenia patients, international scientists say the disorder is a systemic disruption to the brain's entire communication system. The study sets the stage for future research on the debilitating mental illness that affects more than 21 million people worldwide. It is the largest analysis of 'white matter' differences in a psychiatric disorder to date. Source 2i.
Avatar therapy may help to reduce auditory hallucinations for people with schizophrenia. An experimental therapy which involves a face-to-face discussion between a person with schizophrenia and an avatar representing their auditory hallucination may help reduce symptoms, when provided alongside usual treatment, according to a study.

Resilience counteracts effects of childhood abuse and neglect on health. Researchers have determined that psychological resilience has a positive effect on health outcomes for people living with schizophrenia. This is the first study to quantitatively assess the effects of both childhood trauma and psychological resilience on health and metabolic function in people living with schizophrenia. Source 6a.
