Abnormal functional connectivity of the anterior cingulate cortex subregions mediates the association between anhedonia and sleep quality in major depressive disorder

Zenan Wu et al.

Summary: The study found that there are functional connectivity changes between the ACC subregions and certain brain regions in patients with major depressive disorder. In MDD patients, there is a correlation between sleep quality and anhedonia, and the ACC subregions play a mediating role in the relationship between anhedonia and sleep quality.

Poor sleep accelerates hippocampal and posterior cingulate volume loss in cognitively normal healthy older adults

Che Liu et al.

Summary: Poor sleep quality is associated with accelerated volume loss in cognitively-critical brain regions, particularly in the right hippocampus and right posterior cingulate cortex, in healthy older adults. These findings emphasize the importance of addressing sleep quality in cognitive interventions for older adults.

Abnormal Default Mode Network Homogeneity in Major Depressive Disorder With Gastrointestinal Symptoms at Rest

Meiqi Yan et al.

Summary: This study found that patients with major depressive disorder (MDD) who have gastrointestinal (GI) symptoms experience more severe depressive symptoms compared to those without GI symptoms. Distinct patterns in the default mode network (DMN) were also observed in MDD patients with GI symptoms, which can potentially serve as a brain imaging marker for differentiating patients with GI symptoms from those without GI symptoms.

Abnormal regional homogeneity and functional connectivity in major depressive disorder patients with long-term remission: An exploratory study

Zouqing Lin et al.

Summary: This study is the first to explore whether abnormal spontaneous neuronal activities exist in patients in the long-term remission stage of major depressive disorder (MDD). The findings indicate that there are disruptions in regional homogeneity and functional connectivity in the brains of MDD patients, which may contribute to depression relapse.

Summary: This study found that brain functional abnormalities at rest in patients with OCD and showed that anatomical distance has an effect on the whole-brain functional connectivity patterns in OCD. Additionally, lower short-range positive functional connectivity in the left precentral/postcentral gyrus may be used to distinguish OCD from healthy controls.

Abnormal regional homogeneity in right caudate as a potential neuroimaging biomarker for mild cognitive impairment: A resting-state fMRI study and support vector machine analysis

Yujun Gao et al.

Summary: The aim of this study was to explore neuroimaging biomarkers for predicting mild cognitive impairment (MCI) using support vector machine (SVM) classification. Resting-state functional magnetic resonance imaging (rs-fMRI) was performed on 53 MCI patients and 68 healthy controls. The results showed decreased regional homogeneity (ReHo) in the right caudate of MCI patients compared to healthy controls. SVM classification achieved an overall accuracy of 68.6%, sensitivity of 62.26%, and specificity of 58.82%.

Progressive gray matter hypertrophy with severity stages of insomnia disorder and its relevance for mood symptoms

Shumei Li et al.

Summary: The study revealed gray matter volume changes in patients with insomnia disorder at different severity stages, which were related to sleep, mood, and cognitive measures. Increase in gray matter volume was observed in insomnia patients, with slight differences between subthreshold and clinical groups. In the clinical group, mood- and cognitive-related measures were positively correlated with GM volumes, while sleep-related measures showed a negative correlation.

Shared and distinct homotopic connectivity changes in melancholic and non-melancholic depression

Xiaoxiao Shan et al.

Summary: The study revealed common and distinct homotopic connectivity patterns between melancholic and non-melancholic patients. Decreased VMHC in the PCC may be a state-related change for depression, while reduced VMHC in the precentral gyrus and postcentral gyrus may be a distinctive neurobiological feature for melancholic MDD. VMHC in the precentral gyrus could be used as potential imaging markers to differentiate melancholic patients from non-melancholic MDD patients.

Summary: This study used EEG data to investigate differences in brain activity between patients with MDD and healthy adults, finding brain hyperactivity in the right prefrontal lobe and PCC in MDD patients, which are also related to emotion regulation. In future studies, inhibiting high-beta activity or restoring delta and theta activity to the normal range may be possible through z-score neurofeedback protocols.

Summary: MDD patients with GI symptoms show more severe symptoms compared to those without GI symptoms. Increased ReHo values in specific brain regions, particularly related to anxiety/somatization, weight loss, and sleep disturbances, were found in patients with GI symptoms. Increased default-mode network activity may be associated with GI symptoms in MDD patients.
