Dementia Care Research and Psychosocial Factors.

Background: Understand individuals' self-perception of aging is crucial for promoting a positive aging experience, better health with good quality of life, addressing activities participation, and can help by advocating policies and interventions that support the diverse needs of an aging population. This study aims to examine the validity and reliability of the Chinese version of BAPQ (C-BAPQ) for the healthy older people by assessing the content validity, test-retest reliability, and correlational analyses with mental health by Depression, Anxiety, and Stress Scale (DASS-21), quality of life by the Short Form 36 Health Survey (SF-36) and activity participation by the Model of Human Occupation Screening Tool (MOHOST). Moreover, to study the factor structure of the Chinese version of BAPQ (C-BAPQ) by using exploratory factor analysis.

Dementia Care Research and Psychosocial Factors.

Background: Understanding how caregivers perceive their own aging process is essential for addressing their well-being and the quality of care they provide. This study aimed at exploring the relationship between caregivers' self-perception of ageing in relation to their strain experienced in caregiving, and their perceived physical and mental health symptoms. Moreover, to examine if the strain experience and perceived health condition were key predictors to their self-perception of ageing.

Protective effect of Lycium Barbarum polysaccharides on dextromethorphan-induced mood impairment and neurogenesis suppression.

Dextromethorphan (DXM) is one of the common drugs abused by adolescents. It is the active ingredient found in cough medicine which is used for suppressing cough. High dosage of DXM can induce euphoria, dissociative effects and even hallucinations.

Repeated, high-dose dextromethorphan treatment decreases neurogenesis and results in depression-like behavior in rats.

Abuse of cough mixture is increasingly prevalent worldwide. Clinical studies showed that chronic consumption of cough mixture at high dosages may lead to psychiatric symptoms, especially affective disturbances, with the underlying mechanisms remain elusive. The present study aims at exploring the effect of repeated, high-dose dextromethorphan (DXM, a common active component of cough mixture) treatment on adult hippocampal neurogenesis, which is associated with pathophysiology of mood disturbances.
