Survey of brain cell junctions shows striking similarities between schizophrenia and bipolar disorder

Although bipolar disorder and schizophrenia are diagnosed as distinct psychiatric conditions, both are considerably heritable with molecular roots that are poorly understood. Some people diagnosed with one disorder have symptoms and clinical features in common with the other, supporting the notion that the conditions lie on a spectrum. And human genetics studies have suggested that the junctions between brain cells, known as synapses, play a key role in both conditions.
