Psychosocial Support during the COVID-19 Outbreak in Korea: Activities of Multidisciplinary Mental Health Professionals.

As of April 18, 2020, there have been a total of 10,653 confirmed cases and 232 deaths due to coronavirus disease 2019 (COVID-19) in Korea. The pathogen spread quickly, and the outbreak caused nationwide anxiety and shock. This study presented the anecdotal records that provided a detailed process of the multidisciplinary teamwork in mental health during the COVID-19 outbreak in the country. Psychosocial support is no less important than infection control during an epidemic, and collaboration and networking are at the core of disaster management. Thus, a multidisciplinary team of mental health professionals was immediately established and has collaborated effectively with its internal and external stakeholders for psychosocial support during the COVID-19 outbreak.

Neuropsychological correlates of the proportional impact of white matter hyperintensities on mild to moderate dementia: the MRI 300 study.

BACKGROUND: White matter hyperintensities (WMH) increase cognitive impairment in patients with dementia. OBJECTIVE: We investigated the impact of WMH on the neuropsychological profiles in patients with mild to moderate dementia. METHODS: We consecutively recruited newly diagnosed patients with mild to moderate dementia across South Korea for 1 year. The participants completed neuropsychological tests, magnetic resonance imaging, and structured neurological evaluations. The patients were divided into 3 categories, i.e. minimal, moderate, and severe WMH groups, according to the proportional degree of WMH. RESULTS: 289 patients were recruited; 140 (48.3%) for the minimal WMH group, 99 (34.2%) for the moderate group, and 50 (17.5%) for the severe group. Both advanced age and low general cognitive level were significant contributors to WMH in patients with dementia. After adjusting for age, the neuropsychological correlates of the proportional impact of WMH were frontal executive, language, and attention profiles. However, the only significant neuropsychological correlate was the recognition memory profile after adjusting for both age and general cognitive level simultaneously. CONCLUSION: The results suggest that the most significant neuropsychological profile impacting the burden of WMH in patients with mild to moderate dementia was the recognition memory profile, regardless of age and general cognitive function.

Impact of white matter changes on activities of daily living in mild to moderate dementia.

The association between white matter changes and activities of daily living (ADL) in a large, well-defined cohort of patients with mild-to-moderate dementia (either Alzheimer's disease or subcortical vascular dementia) were investigated. A total of 289 patients were divided into three groups (140 mild, 99 moderate, and 50 severe) depending on the degree of white matter changes as indicated on brain magnetic resonance image scans. Further, we analyzed the three groups' performances on basic and instrumental ADL. The degree of white matter changes was associated with greater age, hypertension, previous history of stroke, higher Hachinski Ischemic Score, worse global cognitive and functional status, and an increased impairment of basic ADL and instrumental ADL. The increased impairment with regard to the severe group's performance on both the basic and instrumental ADL remained significant after adjustment for age and hypertension. Tasks involving physical activities were most significant. This was the first study investigating the association between white matter changes and ADL in a large, well-defined dementia cohort. The present study suggests that severe white matter changes may be associated with higher impairment on both basic and instrumental ADL.
