RESUMEN
Objective: To analyze neuropsychological test identification of neurodegenerative (NMCI) and vascular (VMCI) subtypes of mild cognitive impairment. Methods: 94 normal elderly, 107 NMCI and 32 VMCI were evaluated by neuropsychological tests, such as mini mental state examination(MMSE), auditory verbal memory test (AVMT), Rey-Osterrich complex figure test (CFT), trailmaking test (TMT), Stroop Color Words Test (CWT), Verbal fluency test (VFT) and Clock Drawing Test (CDT). MMSE total score of 3 groups were 28.1?1.6, 26.9?1.8 and 26.2?1.7 , respectively. Results: There are similar global severity between NMCI and VMCI groups. VMCI group performed better than NMCI group in verbal delay memory rather than verbal short memory, or figure memory. Stroop interference effect and TMT interference effect of VMCI group were more powerful significantly than that of NMCI. VMCI group also generated fewer figure copy score on CFT. But there wasn't difference on VFT and CDT. Conclusion: These results suggest that decline in executive function is associated with cerebral vascular factors, and decline in episodic memory (such as verbal delay memory) is associated with neurodegenerative factors.
