Abstract:

While the pathophysiology of schizophrenia and bipolar disorders are poorly understood, researchers have used functional brain imaging in healthy volunteers and individuals with schizophrenia and BPD to map interrelationships between five brain networks. Brain networks are regions that function together and are responsible for its higher activities. Two networks showed diminished interactions in schizophrenia and BPD. On this platform of existing knowledge it was decided to chart the neural pathways on a dissected human brain and relate this to the pathophysiology of schizophrenia and BPD. After sagittally dividing a formalinized human brain, five components of basal forebrain, ventral tegmental area and cingulate gyrus were located on the model. Next, the meso-cortical and meso-limbic pathways were charted out on the brain model. Then the most probable locations of pathology in Types-I and II schizophrenia were pinpointed in these pathways. While obviously speculative, this approach enhances understanding of schizophrenia and BPD in several ways. Networks that are out of balance in both illnesses may be related to certain psychotic symptoms seen in both, such as delusions. This model provides the location of antipsychotic intervention on Dopamine-2 and 5HT-2 receptors for the amelioration of schizophrenia and possibly BPD symptoms. It also enables the neurologist to envisage the pathophysiology of schizophrenia and BPD in a more tangible way. Preliminary feedback from viewers of this model has been very positive. Finally, this brain model paves the way for focused imaging studies for more accurate localization of the pathological brain networks in both conditions.
