MRI Studies

During the 1990s, researchers using MRI technology discovered that antipsychotics shrink the frontal lobes and cause an enlargement of the basal ganglia. In the “Follow-up Magnetic Resonance Imaging” study, researchers reported that the enlargement of the basal ganglia was associated with a worsening of both the positive and negative symptoms of schizophrenia. This was powerful evidence of how the drugs cause chronic illness over time.
