BACKGROUND: The burden on caregivers of patients with dementia has an impact on medical, economic, and social areas. However, not enough attention is given to this burden in Korea. There are also very few reports comparing the burden experienced by caregivers of patients with Alzheimer's disease (AD) and vascular dementia (VD). METHODS: One hundred and forty four Alzheimer's and vascular dementia patients were recruited by nine medical centers in the metropolitan city of Busan and the Gyeongnam province. We evaluated the global dementia state of patients in terms of cognitive functions, behavioral and psychological symptoms of dementia, and the activity of daily living along with caregiver burden with the length of care time per day. The Burden Interview, Caregiver Burden Inventory (CBI), Life Satisfaction Index-Z, Beck Depression Inventory, and Beck Anxiety Inventory were conducted by face-to-face interviews with the caregivers. We compared the differences of caregiver burden related to the cause of dementia and according to dementia severity. RESULTS: There were 98 AD patients (68.1%) and 46 VD patients (31.9%). There were 89 females (61.8%) and 55 males (38.2%). Most of the global dementia states did not differ between AD and VD except for the Barthel index (p<0.05). Most of the caregiver burden tests were scored worse in VD. The differences of CBI-time dependent burden and CBI-developmental burden were statistically significant in all the patients (p<0.05). CONCLUSIONS: Our study suggests that VD patients have more caregiver burden than AD patients and that the physical activity of daily living influences caregiver burden.

BACKGROUND: Behavioral and psychological symptoms (BPSD) are common in dementia. These may be helpful for clinical differentiation between Alzheimer's disease (AD) and vascular dementia (VD). Most previous studies have reported the prevalence and severity of BPSD regardless of severity of progression. However, we evaluated the differences of BPSD by grading dementia progression and including severe cases only. METHODS: 141 dementia outpatients from clinics of Busan-Gyeongnam Dementia Association in Korea were analyzed. All patients were administered the Korean version of the Neuropsychiatric Inventory (K-NPI), the expanded version of Korean Clinical Dementia Rating Scale (CDR), and the Korean version of Mini-Mental State Examination (K-MMSE). RESULTS: There were 95 patients with AD and 46 patients with VD. AD patients revealed higher frequency of manifested BPSD symptoms and most of subscales showed higher composite scores also. But apathy was more severely and frequently manifested in VD. AD patients had more frequent night-time behavior and aberrant motor symptoms above 3 point in CDR 0.5 and VD patients had more frequent apathy symptom above 3 point in CDR 1. CONCLUSIONS: These results suggest that generally AD patients revealed more frequent and severe BPSDs than VD patients. Apathy was a more dominant symptom in VD. It seemed that some of the symptoms were valuable clues for the differential diagnosis even though a better designed study was required.

OBJECTIVES: The purpose of this study is to examine the state of demographic findings with clinical characteristics, cognitive impairment and behavioral psychological symptoms of demented elderly in Busan-Gyeongnam Province. METHODS: Patients with dementia who were registered at nine medical centers in Busan Metropolitan City and Gyeongnam Province were the major subjects of this study. Data was collected by face-to-face interview. The final sample consisted of 144 cases after eliminating several incomplete questionnaires. Based on the collected data, the authors evaluated demographic findings, clinical characteristics, and cognitive impairment and behavioral psychological symptoms of the patients with dementia using statistical analyses. All of the patients were taken the Korean version of Mini-Mental State Examination(K-MMSE), the Clinical Dementia Rating Scale(CDR) and the the Korean version of Neuropsychiatric Inventory(K-NPI). RESULTS: Approximately 61% of the patients with dementia in Busan-Gyeongnam Province were women, and their mean age was 72.9(SD=8.3) years old. Their average education level was 2.3(SD=1.3) years. Among the demented elderly, Alzheimer's disease accounted for 68% compared with vascular dementia(32%) and the proportion of mild stage of dementia was above 50%. The mean K-MMSE score was 16.7(SD=6.2), the mean CDR score was 1.3(SD=0.8), and the Barthel Index with K-IADL score were 16.7(SD=5.4) and 1.5(SD=0.9). The average score of K-NPI was 22.6(SD=22.5) and the number of manifested K-NPI was 4.9(SD=2.8). The K-NPI score has increased in demented elderly as the severity of dementia getting worse according to the CDR score. The number of manifested K-NPI was significantly more prevalent in patients with AD than that of patients with VD. CONCLUSION: This study is a meaningful approach to the state of demographic findings, clinical characteristics, cognitive impairment and behavioral psychological symptoms associated with the dementied elderly who were comprehensively examined in Busan-Gyeongnam Province. Based on this study, we found that the demographic information was comparable with other epidemiologic study in Korea and our study patients were relatively mild stage of demenitia according to the assessment of cognition and behavioral symptom scales.

BACKGROUND: The purposes of this study were to examine the state of depression and life satisfaction of family caregivers and to find out which factors would be significant in determining depression and life satisfaction of caregivers for the elderly with dementia. METHODS: Caregivers of patients with dementia who were registered at nine medical centers in Busan Metropolitan City and Gyeongnam Province were the major subjects of this study. Data was collected by face-to-face interviews. The final sample consisted of 144 cases after eliminating several incomplete questionnaires. Based on the collected data, the authors evaluated demographic findings, general characteristics, and factors influencing depression and life satisfaction of the caregivers using statistical analyses. RESULTS: The severity of depression and the degree of life satisfaction in family caregivers were low. We found that caregiver's anxiety, monthly income, caregiver burden, non-relative network, self-confidence of caregiving, and the degree of the Barthel index of activity of daily living (B-ADL) were significant factors in determining depression of the caregivers (p<0.05). The following two variables were significant factors in determining the caregiver's level of life satisfaction: burden of caregiving costs and patient's Korean mini-mental state examination (K-MMSE) score (p<0.05). CONCLUSIONS: Our results showed that the level of anxiety, caregiver burden and social support, rather than the conditions of dementia patients, influenced depression and life satisfaction for the caregivers of patients with dementia. Therefore, in order to improve the quality of life for caregivers, we should consider psychosocial factors as well as patient's medical factors in influencing depression and life satisfaction.

BACKGROUND: The differences in clinical features are important when differentiating between Alzheimer's disease (AD) and vascular dementia (VD). There have been many studies comparing the severity of progression in both diseases. They have assessed individual symptoms but have not explained the differences and global change of progression comprehensively. We have evaluated the cognitive and non-cognitive functions at the same time and evaluated the differences between AD and VD. METHODS: One hundred and thirty-eight dementia patients from Busan?Gyeongnam Dementia Association outpatient clinics were analyzed. All of the patients underwent the Korean version of the Mini-Mental State Examination (K-MMSE), the expanded version of the Korean Clinical Dementia Rating Scale (CDR), the Korean version of the Neuropsychiatric Inventory (K-NPI), the scales for activity of daily living, and the Short form of the Samsung Dementia Questionnaire (S-SDQ). RESULTS: There were 93 patients with AD and 45 with VD. VD patients revealed more severe Barthel Index of Activity of Daily Living (B-ADL) deficits. AD patients had more severe memory and orientation deficiency in CDR 1 and CDR 2. VD patients revealed much faster decline of K-MMSE score between CDR 2 and CDR 3. CONCLUSIONS: These results suggest that VD patients display more severe B-ADL difficulty, while AD patients display more severe memory difficulty and disorientation. B-ADL progresses in the earlier stages in VD and in the later stages in AD. Global cognitive dysfunction progression is the opposite: in the earlier stages in AD and in the later stages in VD.
