Looking at comorbidity through the glasses of neuroscientific memory research: a brain-network perspective

As psychiatric illnesses have correlates in the brain, it is surprising that Cramer et al. make almost no reference to the brain's network character when proposing a network approach to comorbidity of psychiatric diseases. We illustrate how data from combined neuropsychological and functional and structural brain-imaging investigations could inform theoretical models about the role played by overlapping symptoms in the etiology of psychiatric comorbidity and the pathways from one disorder to another.
