Depression in the elderly population has shown increased likelihood of neurological disorders due to structural changes in the subcortical area. However, further investigation into depression related subcortical changes is needed due to mismatches in structural analysis results between studies as well as scarcities in research regarding subcortical connectivity patterns of subclinical depression populations. This study aims to investigate structural differences in subcortical regions of aged participants with subclinical depression using 3Tesla MRI. In structural analysis, volumes of each subcortical region were measured to observe the volumetric difference and asymmetry between groups, but no significant difference was found. In addition, fractional anisotropy (FA) and apparent diffusion coefficient (ADC) did not show any significant differences between groups. Structural analysis using probabilistic tractography indicated that the connection strength between left nucleus accumbens-right hippocampus, and right thalamus-right caudate was higher in the control group than the subclinical depression group. The differences in subcortical connection strength of subclinical depression groups, have shown to correlate with emotional and cognitive disorders, such as anxiety and memory impairment. We believe that the analysis of structural differences and cross-regional network measures in subcortical structures can help identify neurophysiological changes occurring in subclinical depression.

Background: Climate distress is a psychological reaction to adverse weather events and climate change. These events can increase people's vulnerability to develop psychiatric disorders like anxiety, depression, and PTSD particularly in disaster-prone regions like India.
Aim: To explore the relationship between climate distress and psychological impact with a particular emphasis on women, elderly, and other at risk populations who owing to their health vulnerabilities, lack of resources or social roles that make them dependent on others, experience stress in the face of climate change.

Psychotic-like experiences (PLEs) -subclinical experiences or symptoms that resemble psychosis, such as hallucinations and delusional thoughts-often emerge during adolescence and are predictive of serious psychopathology. Understanding PLEs during adolescence is crucial due to co-occurring developmental changes in neural reward systems that heighten the risk for psychotic-related and affective psychopathology, especially in those with a family history of severe mental illness (SMI). We examined associations among PLEs, clinical symptoms, and neural reward function during this critical developmental period.

Introduction: Receiving an Alzheimer's disease (AD) diagnosis can be a distressing experience, for both the individual with the condition and the family. This cross-sectional study explored whether the disclosure of AD diagnosis generated post-traumatic stress symptoms (PTSSs) in caregivers and how this affected their psychological well-being.
Methods: Seventy-nine caregivers completed the Impact of Event Scale to assess any PTSSs related to the memory of AD disclosure and clinical scales to assess current psychological distress.

Background: Cancer survivors often experience depression and stigma associated with chronic diseases, which may increase the risk of subclinical hikikomori.
Aims: This study examined the prevalence of subclinical hikikomori and its nonlinear associations with depression and stigma among cancer patients.
Methods: A cross-sectional survey was conducted among 1951 cancer survivors.

The prevalence of postpartum mental illness is steadily increasing, a tendency that was exacerbated by the COVID-19 pandemic. Recent studies show that maternal depression is no longer confined to the perinatal period, and this necessitates long-term assessment and support for maternal mental health. It is critical to identify the factors that are related to depression among mothers, and this requires the development of integrated mental and physical health care encompassing both psychological aspects and intestinal microbiota, physical conditions, and dietary habits.
