Objective: Reduced hippocampal volume and alterations in white matter tracts have been frequently reported in adults having the history of emotional maltreatment. We investigated whether these structural change occur in adolescents with previous verbal abuse (VA) experiences.
Methods: Hippocampal subfield volume and white matter structural connectivity measures were assessed in 31 first year male high school students with various degrees of exposure to parental and peer VA.
Results: The high VA group showed significant volume reduction in the left cornu ammonis (CA) 1 and left subiculum compared to the low VA group (<0.05). Volumes of left hippocampal subfields CA1 and subiculum were negatively correlated with previous VA experiences (<0.05). Increased mean diffusivity (MD) of the splenium of the corpus callosum was related to high VA score across all subjects (<0.05). There was an inverse relationship between volume of the CA1 and subiculum and MD of the splenium (<0.05).
Conclusion: Exposure to parental and peer VA may affect development of the left hippocampal subfields and the splenium of corpus callosum. These structural alterations can be discernible during adolescence.

Background: Previous studies indicate that hippocampal (subfield) and amygdala volumes may correlate with specific cognitive functions, coping strategies and emotion regulation. Here, we investigated associations between emotional processing and volumes of hippocampal subfields and amygdala. We focused on depressed patients since emotional dysregulation and hippocampal volume shrinkage are characteristic of them.

Background: This study investigates structural abnormalities in hippocampal subfield volumes and shapes, and their association with plasma CC chemokines in individuals with major depressive disorder (MDD).
Methods: A total of 61 patients with MDD and 65 healthy controls (HC) were recruited. All participants underwent high-resolution T1-weighted imaging and provided blood samples for the detection of CC chemokines (CCL2, CCL7, and CCL11).

Background: The hippocampus plays a critical role in psychosis, with reduced volume observed across the psychosis continuum. These structural changes are associated with cognitive deficits, symptom severity, and increased risk of psychosis progression. Elevated hippocampal perfusion and glutamate/GABA (gamma-aminobutyric acid) imbalance further suggest metabolic dysregulation as a key mechanism.

Alterations in hippocampal structure and function are established in schizophrenia. However, the specific patterns of hippocampal activity along the schizophrenia course remain unknown. Eighty-five study participants [34 schizophrenia probands (SZ), 32 first-degree relatives (REL), 19 healthy controls (HC)] underwent 3Tesla ultra-high resolution brain MRI (Vascular Space Occupancy); relative cerebral blood volume (rCBV)-an index of regional activity-was estimated across hippocampal subfields: dentate gyrus (DG), CA3, CA1, and subiculum (SUB).

Background: High blood pressure (BP) is a known risk factor for cognitive decline and dementia, but the underlying mechanisms are largely unknown. We investigated the associations of cumulative BP exposure with hippocampal subfield volume and cognitive function and determined whether hippocampal subfield atrophy mediates the association between cumulative BP exposure and cognitive decline.
Methods: Between December 2020 and March 2023, participants were prospectively included from the Kailuan study.
