Restless legs syndrome (RLS) is a common disorder for which agents that enhance dopaminergic activity, including dopamine agonists and levodopa, are the treatment of choice. However, long-term use of dopaminergic drugs can cause unwanted effects such as rebound, tolerance, and augmentation. Bupropion, an inhibitor of dopamine and noradrenalin reuptake, is(More)
BACKGROUND The association between methylenetetrahydrofolate reductase (MTHFR) c.677C>T (A222V) polymorphism and Alzheimer's disease (AD) is controversial. The objectives of the study were to investigate the association between MTHFR c.677C>T polymorphism and AD in Korean elders and to the extent to which it is modified by the major components of one-carbon(More)
BACKGROUND Restless legs syndrome is a common neurologic disorder, and there is increasing evidence for a dopaminergic link between Parkinson's disease and restless legs syndrome. However, most previous studies did not take into account the effects of dopaminergic medication. We conducted a nation-wide, cross-sectional study to determine the prevalence and(More)
OBJECTIVES Dementia has rapidly increased with the prolongation of life expectancy and aging in Korea. This study was conducted to estimate the prevalence of, and find related factors for, dementia in an urban elderly population, using a newly developed screening method. METHODS Seven hundred and six people, aged over 65 years-old, in Dong district of(More)
OBJECTIVES The Quality of Life-Alzheimer's Disease (QOL-AD) scale is a reliable and valid tool for assessing the quality of life (QOL) in the elderly with dementia. This study aimed to develop the Korean version of Quality of Life-Alzheimer's Disease (KQOL-AD) scale for the demented elderly living in the community. METHODS KQOL-AD was administered to two(More)
OBJECTIVE Depression is common after acute coronary syndrome (ACS) and has adverse effects on prognosis. There are few evidence-based interventions for treating depression in ACS. This study investigated the efficacy and safety of escitalopram in treating depressive disorders identified 2-14 weeks after a confirmed ACS episode. METHOD A total of 217(More)
BACKGROUND Acetaldehyde, the first product of ethanol metabolization, is a biologically active compound, but the behavioral properties of acetaldehyde in humans are largely undefined. We investigated the acute effects of both alcohol and acetaldehyde on psychomotor functions related to automobile driving skills. METHODS Twenty-four men were selected(More)
BACKGROUND This study investigated the acute effects of ethanol and acetaldehyde on physiological responses in healthy men according to ALDH2 genotype by measuring them directly in human blood. METHODS Twenty-four men, 12 with the ALDH2*1/*1 genotype and 12 with the ALDH2*1/*2 genotype, were selected. In a double-blind placebo-controlled crossover design,(More)
BACKGROUND Caregiver strain was investigated in a community sample of Korean elders with cohabiting caregivers, and factors associated with this were compared between groups classified by cognitive and functional impairment. METHODS The study sample consisted of 484 elders and their cohabiting caregivers resident in Kwangju, South Korea. Caregiver burden(More)
OBJECTIVE Cross-sectional studies have shown that the dysregulation of one-carbon metabolism is associated with cognitive impairment. However, the findings of longitudinal studies investigating this association have been inconsistent. This study investigated the prospective associations between cognitive decline and the levels of folate, vitamin B(12) and(More)
