An analysis of brain scans from more than 300 patients suggests two distinct neuroanatomical subtypes of schizophrenia. Researchers published the findings online in the journal Brain.
“In the future, we’re not going to be saying, ‘This patient has schizophrenia.’ We’re going to be saying, ‘This patient has this subtype’ or ‘this abnormal pattern,’ rather than having a wide umbrella under which everyone is categorized,” said principal investigator Christos Davatzikos, PhD, the Wallace T. Miller Professor of Radiology in the Perelman School of Medicine at the University of Pennsylvania in Philadelphia… Continue reading.
Schizophrenia is a complex neurological condition characterized by disorganized thinking, difficulty concentrating, hallucinations, and delusions. Affecting up to 1% of people worldwide, the cause and disease mechanisms of schizophrenia are not well understood.
The present study, led by principal investigator Christos Davatzikos, PhD, the Wallace T. Miller professor of radiology in the Perelman School of Medicine at the University of Pennsylvania, examined the brain anatomy of people with schizophrenia. Davatzikos’s team used a large, diverse sample of volunteers that spanned three continents. Working with researchers in Germany, Italy, and the UK, they analyzed the brains of 307 schizophrenia patients and 364 healthy people included as controls… Continue reading.
Adolescence marks not only the period of physical maturation bridging childhood and adulthood, but also a crucial period for remodeling of the human brain. A Penn study reveals new patterns of coordinated development in the outer layer of the cerebrum of the human brain and describes how these structural patterns relate to functional networks.
The team found the convergence between structural and functional networks was inversely related to functional complexity. Motor, sensory, visual and functional networks aligned to distinct structural networks. This unique representation of maturation may open new opportunities for future studies into many psychiatric disorders that might begin during this age. A team from the Perelman School of Medicine at the University of Pennsylvania publishes the findings this week in the Proceedings of the National Academy of Sciences… Continue reading.
