Predictores de enfermedad de Alzheimer en pacientes con deterioro cognitivo leve

Abstract

The goal of this research was to identify clinic markers as Alzheimer's disease (AD) predictors in patients with mild cognitive impairment (MCI). A longitudinal study was accomplished including patients ranging from 50 year's olds and older, which were divided in two groups (MCI=40 and Controls=26). These patients were recruited from memory clinic-based sample at Dr. Carlos J. Finlay Hospital in a period that lasted from November/2003 to July/2006. Mini Mental State Exam (MMSE) and three subtest of Wechsler memory scale were applied to all of them. A 20.5% of patients with MCI exhibited conversion to AD. The average time for conversion was 18.12 month. The average age was higher in those that made conversion. Educational level was significantly lower in patients with MCI that made conversion to Alzheimer. Family pathological records were found in 75% of converters patients. Results of MMSE were similar in patients that converted as those that not converted. Mean punctuation of Wechsler subtest was lower in converters patients. Logical memory A, Hard Associative Learning, and Total Score were distinguished as those with bigger predictive value.
