We employed a fundamentally different approach and investigated how much the brains of individual patients diagnosed with schizophrenia and bipolar disorder differ from one another. For this purpose, we selected brain scans from healthy individuals to model a norm reflecting the healthy range, subsequently we compared the brain scans of patients with schizophrenia and bipolar disorder to this norm on the level of the individual.
The main outcome was that individuals with schizophrenia and bipolar disorder differ substantially from one another, thus, considering only the ‘average patient’ has little to say about what might be occurring in the brain of an individual patient. Continue reading
