Context Magnetic resonance imaging studies have identified hippocampal volume
reductions in schizophrenia and amygdala volume enlargements in bipolar disorder …

Using magnetic resonance imaging of the brain, we examined volumetric measurements of
total brain, hemispheres, lateral ventricles and the hippocampus/amygdala complex in male …

Cross-sectional studies suggest that hippocampal volume declines across stages of
psychosis. In contrast, longitudinal studies indicate that hippocampal volume is stable in the …

Background It has been proposed that the hippocampus is a potential site for a
neurodevelopmental lesion in schizophrenia. While smaller hippocampal volumes have …

Background Although many quantitative magnetic resonance imaging studies have found
significant volume reductions in the hippocampi of patients with schizophrenia compared …

Brain abnormalities have been identified in patients with schizophrenia, but what is unclear
is whether these changes are progressive over the course of the disorder. In this longitudinal …

BACKGROUND: Hippocampal volume (HV) reduction is well documented in schizophrenia.
However, it is still unclear whether this change is a pre-existing vulnerability factor, a sign of …

Volumes of the mesiotemporal structures (hippocampus-amygdala complex) were
measured in 19 men who were chronic multipisode schizophrenics and 18 age-matched …

Previous research using MRI scans has shown reduced hippocampal volumes in chronic
schizophrenia and first-episode psychosis compared to well subjects. There are few MRI …

Although the hippocampus is a key brain region in the pathophysiology of schizophrenia, it
is unclear whether structural or biochemical abnormalities predate illness onset. In this …
