Microvessel length density, total length, and length per neuron in five subcortical regions in schizophrenia.

Recent studies (Prabakaran et al. in Mol Psychiat 9:684-697, 2004; Hanson and Gottesman in BMC Med Genet 6:7, 2005; Harris et al. in PLoS ONE 3:e3964, 2008) have suggested that microvascular abnormalities occur in the brains of patients with schizophrenia.

Volume, neuron density and total neuron number in five subcortical regions in schizophrenia.

Several studies have pointed to alterations in mean volumes, neuron densities and total neuron numbers in the caudate nucleus (CN), putamen, nucleus accumbens (NA), mediodorsal nucleus of the thalamus (MDNT) and lateral nucleus of the amygdala (LNA) in schizophrenia. However, the results of these studies are conflicting and no clear pattern of alterations has yet been established in these subcortical regions, possibly due to differences in quantitative histological methods used as well as differences in the investigated case series. The present study investigates these subcortical regions in both hemispheres of the same post-mortem brains for volume, neuron density and total neuron number with high-precision design-based stereology.
