Cognitive function in aging is influenced by more than just age and education. Individual factors like work history and leisure activities significantly impact memory and executive functions in older adults.

Area of Science:

  • Neuroscience
  • Psychology
  • Gerontology

Background:

  • Normal aging is associated with cognitive changes.
  • Understanding factors influencing cognitive performance is crucial for healthy aging.

Purpose of the Study:

  • To analyze the effects of demographic and individual variables on memory and executive function.
  • To identify key factors associated with cognitive performance in normal aging.

Main Methods:

  • Sixty healthy older adults (mean age 69.66) were assessed.
  • Neuropsychological tests included Wechsler Memory Scale, AMSET, Wisconsin Card Sorting Test, and Verbal Fluency.
  • Demographic (age, education, sex) and individual (academic, work, physical activity, leisure) variables were analyzed.

Main Results:

  • Age and education significantly affected test scores; sex did not.
  • Working history and leisure activities showed significant differences in some cognitive scores.
  • Multiple regression revealed both demographic and individual variables are associated with memory and executive function.

Conclusions:

  • Cognitive performance in normal aging is influenced by a combination of demographic and individual factors.
  • Individual variables, such as work history and leisure engagement, play a significant role in cognitive aging.
  • These findings highlight the importance of lifestyle factors in maintaining cognitive health during aging.
