AI Article Synopsis

  • The study aimed to explore brain structure differences in newly diagnosed, drug-free patients with major depressive disorder and panic disorder compared to healthy individuals.
  • Utilizing high-resolution magnetic resonance imaging and voxel-based morphometry, researchers found significant reductions in gray matter volumes in multiple brain regions, including the anterior cingulate cortex and limbic areas among patients.
  • The results indicate that these gray matter volume deficits may be linked to the default-mode network and could have begun at the onset of the disorders.

Article Abstract

This study was designed to investigate the structural differences in the brains of first episode, drug-naïve patients with major depressive disorder and panic disorder versus healthy control subjects. High-resolution brain magnetic resonance images were performed on patients and health control subjects (age, sex and handedness matched). Structural magnetic resonance images of brain were estimated by optimized voxel-based morphometry of FSL (FMRIB Software Library). Patients had deficits of gray matter volumes over right anterior cingulate cortex, right medial frontal gyrus, left posterior cingulate cortex, right parahippocampal gyrus, limbic areas, occipital lingual gyrus and bilateral cerebellums when compared to controls. These results suggested that this group of patients has possible deficits of gray matter volumes over the default-mode network, fronto-cingulate and limbic structures. The decline of gray matter volumes might have started since the first episode.

Background: Cerebrospinal fluid (CSF) loss in spontaneous intracranial hypotension (SIH) is accompanied by volume shifts between the intracranial compartments. This study investigated tricompartimental and longitudinal volume shifts after closure of a CSF leak.

Methods: Patients with SIH and suitable pre-therapeutic and post-therapeutic imaging for volumetric analysis were identified from our tertiary care center between 2020 and 2023.

The impacts of air pollution, local climate, and urbanization on human health have been well-documented in recent studies. In this study, we combined magnetic resonance imaging (MRI) brain analysis with a questionnaire survey on the local environment in 141 healthy middle-aged men and women. Our findings reveal that a favorable environment is positively correlated with gray matter volume (GMV) in the frontal and occipital lobes, cerebellum, and whole brain, as well as with fractional anisotropy (FA) in the fornix (including the fornix stria terminalis), posterior thalamic radiation (PTR), sagittal stratum (SS), and whole brain.

Introduction: Lung function has been associated with cognitive decline and dementia, but the extent to which lung function impacts brain structural changes remains unclear. We aimed to investigate the association of lung function with structural macro- and micro-brain changes across mid- and late-life.

Methods: The study included a total of 37 164 neurologic disorder-free participants aged 40-70 years from the UK Biobank, who underwent brain MRI scans 9 years after baseline.

The brain entropy (BEN) reflects the randomness of brain activity and is inversely related to its temporal coherence. In recent years, BEN has been found to be associated with a number of neurocognitive, biological, and sociodemographic variables such as fluid intelligence, age, sex, and education. However, evidence regarding the potential relationship between BEN and brain structure is still lacking.

Background: Sudden sensorineural hearing loss (SSNHL) is associated with abnormal changes in the brain's central nervous system. Previous studies on the brain networks of SSNHL have primarily focused on functional connectivity within the brain. However, in addition to functional connectivity, structural connectivity also plays a crucial role in brain networks.
