ABSTRACT
Objective To investigate the frequency and location of cerebral microbleeds(CMB) in dementia with Lewy bodies(DLB)versus in Alzheimer's disease(AD).Methods This retrospective study included three groups of probable AD patients (n =156),dementia with Lewy bodies (n =67) and normal controls(n=172).Frequencies and location of CMBs in the three groups were calculated and recorded.The foci of MRI signal for CMB were confirmed by two radiologists at moments of unknowingness about diagnosis.The correlations of cerebral small vessel disease and cerebral amyloid angiopathy with the development of cognitive decline in AD were analyzed.Results The incidence rate of CMBs was higher in patients with groups of DLB(22.4 ％,15/67) and AD(19.8 ％,31/156) than in normal controls (8.2 ％,14/172) (P =0.002 and 0.002),while there was no significant difference in incidence rate of CMBs between DLB and AD groups(P＞0.05).The MRI signal intensity of CMBs was the highest in the occipital lobe of the DLB group,and was higher in the deep temporal lobe or temporal lobe in the AD group.Conclusions The frequency of CMB is higher in patients with DLB or AD than in normal controls and there is no significant difference in frequency of CMB between DLB and AD groups,which suggests that the pathophysiological mechanisms of CMB may be similar between AD and DLB.
ABSTRACT
Objective To compare cognitive ,behavioral ,and psychological symptoms observed in Alzheimer's disease (AD ) and dementia with Lewy body (DLB ) in order to provide helpful information for differential diagnosis. Methods We selected 215 patients with AD (AD group)and 66 patients with DLB(DLB group)to retrospectively analyzed their general information ,family history , and disease history.The Mini-Mental State Examination(MMSE scale)was used to evaluate cognitive abilities and Neuropsychiatric Inventory ( NPI scale ) was used for analysis of behavioral and psychological symptoms of dementia in both groups. Results The prevalence of hypertension was higher in the AD group(52.6%,n＝113)than in the DLB group(40%,n＝24)(P＜0.05).The DLB group showed better general cognitive scores ,disorientation scores ,immediate recall scores ,and delayed recall scores than the AD group. Fluctuating cognitive deficiencies and Parkinson's symptoms were more prevalent in the DLB group than in the AD group with 2 patients (0.9%) showing fluctuating cognitive deficiencies in the AD group ,and 19(28.8%)in the DLB group(χ2＝8.580 ,P＝0.003) ;with 26 patients(12.1%)showing Parkinson's symptoms in the AD group and 25(37.9%)in the DLB group(χ2＝ 22.602 ,P＝ 0.000).As to behavioral and psychological symptoms ,the DLB group had higher scores in total NPI ,hallucinations and nighttime abnormal behaviors with 32 patients (14.9%)showing hallucinations and 64 (29.8%)showing nighttime abnormal behaviors in the AD group ;30(46.2%)showing hallucinations and 30 (46.2%)showing nighttime abnormal behaviors in the DLB group (all P ＜ 0.05 ) . Conclusions Hypertension is more prevalent in AD patients. Fluctuating cognitive deficiencies ,Parkinson's symptoms ,hallucinations ,and nighttime abnormal behaviors are prominent manifestations in DLB patients.
ABSTRACT
Objective To investigate the status of life quality in the elderly in Shanxi Province Changzhi City, and to analyze its influencing factors. Methods The quality of life, activities of daily living and status of community services were measured simultaneously by 36-Item Short Form Health Survey (SF-36). Activities of Daily Living Scale, Community Healthy Needs Scale and survey results were used and analyzed using t-test, correlation and stepwise regression analysis. Results According to the criterion of life quality in the elderly which were proposed by Zhang Lei, the quality of life in the elderly scored 72. 1-117.0, reached 98.5%. The quality of life in the elderly was impacted by the ability of caring oneself, marital status, degree of culture, economic situation and so on. The demand rate for health guidance and periodic physical examination was higher. Conclusions The quality of life in the elderly is at a medium level. There is a wide gap between the demand of community healthy services and the utilization of community healthy services.
ABSTRACT
Objective To investigate the quality of life of elderly caregivers and its factors. Methods Elderly caregivers living in Changzhi City were enrolled in this study. 36-item short-form (SF-36) health survey and Activity of Daily Living Scale ( ADL) were used as study tools. The data was analyzed by statistical description,t test or multiple regression. Results Those with score of quality of life reaching 72. 1 to 117. 0 accounted for 98. 8%. The total score and score of eight dimensions of SF-36 showed statistically significant difference between different daily living activity groups ( P < 0.05) . The state of health and self-care ability of the elderly imposed a major impact on eight dimensions of SF-36. Age, sex, level of education, marital status and wage had different impact on each dimension of SF-36. Conclusion The quality of life of elderly caregivers is at a medium level. The main factors of quality of live of elderly caregiver are their state of health and self-care ability of the elderly.
