Summary: Body integrity dysphoria (BID) is a severe condition that affects nonpsychotic individuals. In the amputation variant of BID, a limb may be experienced as not being part of the body. Altered patterns of white matter structural connectivity were identified in individuals with BID, suggesting involvement in the processing of sensorimotor representations and body image.

Summary: Financial decision-making and financial awareness are both crucial for preventing financial mistakes. Our study found that financial decision-making was negatively correlated with the average mean diffusivity of the temporal-parietal and temporal-frontal tracts, while financial awareness was positively correlated with the average mean diffusivity of the right temporal-frontal tract. These preliminary findings support the unique role of right hemisphere temporal connections in supporting financial awareness.

Summary: This study examined the association between late-life depressive symptoms and white matter structural integrity in 297 older Black participants without dementia. The results showed that higher levels of depressive symptoms were associated with reduced white matter integrity in specific brain regions.

Summary: Research has shown that individuals with obesity tend to have lower white matter integrity, particularly in the genu of the corpus callosum, a tract linking areas involved in executive function. Further studies are needed to explore the mechanisms linking obesity with loss of white matter integrity.

Summary: This longitudinal study found a dynamic relationship between whole-brain white matter microstructural integrity and anxiety symptoms in girls with pathological anxiety. The findings suggest that targeting white matter development could be a viable approach in the treatment of anxiety-related psychopathology.

Summary: A study revealed that in CSVD patients, disrupted DMVs cause an increase in interstitial fluid, leading to white matter damage. This link is independent of arterial perfusion variations and warrants further investigation.

Summary: This study reveals the pathophysiological mechanisms of bipolar disorder patients with suicide attempts (BD + S). The results show abnormalities in peripheral plasma inflammatory cytokines and brain white matter integrity in BD + S patients. Increased levels of IL-6 were found in the plasma, and decreased fractional anisotropy (FA) values were observed in specific regions of the brain in BD + S patients.

Summary: Nicotine addiction is a neuropsychiatric disorder that affects the function of brain cortices and white matter. This study used the small-world model to compare white matter functional connectivity between nicotine addiction participants and healthy controls. The results showed that the nicotine addiction group had decreased small-worldness index and normalized clustering coefficient compared to controls. These findings suggest that WM functional changes and small-world properties could be potential biomarkers in nicotine addiction.

Summary: This study explores the relationship between obesity and brain health, specifically focusing on the differences between males and females. The findings suggest that there are sex differences in the association between adiposity and intelligence as well as white matter microstructure. This highlights the importance of considering sex-driven differences when studying the impact of obesity on brain degeneration.

Summary: This study investigates the specific characteristics of the structural brain network in patients with panic disorder (PD) using diffusion tensor imaging (DTI) and graph theory analysis. The results show that PD patients have higher network efficiency, lower shortest path length, and lower clustering coefficient at the global level compared to healthy controls. At the nodal level, PD patients exhibit higher nodal efficiency and lower average shortest path length in regions such as the prefrontal cortex, sensorimotor cortex, limbic system, insula, and cerebellum. These findings suggest that alterations in the fear network's information processing may contribute to the pathophysiology of PD.

Summary: This study aimed to investigate the relationship between skeletal muscle energy metabolism and body composition in healthy adults. The results suggest that increased adiposity is associated with reduced muscle energetic efficiency and more reliance on glycolysis.
