Abstract:

Abstract Introduction Socio - demographic and genetic factors have been involved in the development of cognitive impairment and its progression to dementia . Method The present study evaluates socio - demographic characteristics and the ApoE genotype in individuals older than 55 years with mild cognitive impairment ( MCI ) and Alzheimer's disease ( AD ) , attending a memory clinic . Results 155 individuals ( 36% ) out of the total population who attended the memory clinic in a four - year period met the inclusion criteria . The study population was classified in diagnostic groups according to the _Diagnostic and Statistical Manual of Mental Disorders_ ( DSM - IV - TR ) and to the National Institute of Neurological and Communicative Disorders and Stroke and Alzheimer's Disease and Related Disorders Association ( NICNCDS - ADRDA ) criteria . More AD and MCI individuals worked in mainly manual occupations throughout their lifetime compared to cognitively unimpaired individuals ( _p_ =0 .014 ) . A high percentage of individuals with MCI and of cognitively unimpaired individuals ( 43% ) left their primary occupation or changed it for a mainly manual occupation after their retirement . No other factors associated to the cognitive impairment , including ApoE genotype , were found . Conclusion These results support a correlation between the primary occupation during lifetime and the development of cognitive impairment in individuals older than 55 years .
