Objective To identify the differences inneuropsychological characteristics between amnestic(AMCI)and vascular mild cognitive impairment(VMCI).Methods Totally 297 old community residents with mild cognitive impairment(MCI)were divided into amnestic MCI(AMCI)and vascular MCI(VMCI)subgroup from Guangzhou MCI prevalence survey.The elderly with MCI were interviewed and tested with the Chinese version of Montreal Cognitive Assessment(MoCA),the Mini-Mental state examination(MMSE),Auditory Verbal Learning Test(AVLT),the Clinical Dementia Rating scale(CDR),Functional Activity Questionnaire(FAQ),the Modified Hachinski Ischemic Scale(M-HIS),Center for Epidemiologic Studies(CES-DC)to evaluate neuropsychological characteristics.Results AMCI versus VMCI group showed that the total scores of MoCA were(9.63±5.17 vs.9.98±6.02),total scores of MMSE were(16.90±4.84 vs.16.90±6.19),AVLT immediate memory was(2.35±1.39 vs.2.91±1.84),AVLT delayed recall was(2.23±2.09 vs.2.47±2.20),AVLT delayed recognition was(7.33±3.98 vs.6.85±4.02)and total scores of CDR(0.5 vs.0.5),with no differences between the 2 groups(all P>0.05).Based on MoCA survey,AMCI versus VMCI group showed statistically significant differences(all P<0.05)in parameters of visual space and execution(0.71±1.02 vs.0.92±1.26),language function(0.34±0.56 vs.0.50±0.80)and abstract thinking(0.25±0.49 vs.0.15±0.43),but based on MMSE survey,no difference was found in the various cognitive domains between the two groups.The AMCI versus VMCI group showed statistically significant differences(all P<0.05)in parameters of CES-DC scale(1.75±4.27 vs.2.76±6.72),FAQ scale(4.42±4.66 vs.8.71±7.03),M-HIS scale(0.40±0.64 vs.7.59±3.53).Conclusions There is no significant difference in general cognitive impairment between AMCI and VMCI,but the visual space and execution,language function are more impaired in AMCI than VMCI,and the abstract thinking,social function are more impaired with more depressive symptoms in VMCI than in AMCI.

Objective To investigate the difference in behavioral and psychological symptoms among Al-zheimer's disease(AD)patients with different severity of white matter hyperintensity(WMH). Methods A total of 37 AD patients were enrolled and were followed-up for 4 weeks. They were checked by 3.0 T MRI at baseline, including T1,T2-weighted phase and fluid-attenuated inversion recovery sequence(FLAIR phase).The image pro-fessionals analyzed the images and process data.The Fazekas scale was used for WMH rating.Assessment tools in-cluded the Neuropsychiatric Inventory(NPI)、MMSE and ADAS-cog. Results There were 14 patients in none-mild WMH group and 23 patients in moderate-severe WMH group. The age of two groups were 71.3 ± 12.5 and 78.7 ± 6.1 years old respectively(P<0.05).The comparison of NPI,MMSE and ADAS-cog assessment results be-tween two groups show that there is significance difference in NPI baseline scoring and 4-week scoring.The score in moderate-severe group w is higher than that in the none-mild group(P < 0.05). However,the changed value of baseline-4-week NPI is not statistically significant. There is no significant difference between MMSE and ADAS -cog score and changed value.Conclusion Taken together,the severity of WMH may be related to behavioral and psychological symptoms of patients with Alzheimer's disease.
