High performance older adults in a population-based sample with low education: Pietà study

Area of Science:

• Neuroscience
• Gerontology
• Cognitive Psychology

Background:

• Healthy brain aging is defined by the absence of neurological or psychiatric disorders and sustained functional independence.
• High-performance older adults (HPOA) exhibit superior cognitive test performance compared to age-matched peers.
• This study investigates HPOA in an oldest-old population with limited education.

Purpose of the Study:

• To determine the prevalence of HPOA in an oldest-old cohort with low educational attainment.
• To explore sociodemographic, clinical, and lifestyle factors associated with HPOA in this population.

Main Methods:

• The Pietà Study evaluated 132 cognitively healthy individuals.
• High-performance older adults (HPOA) were identified using delayed recall from the Rey Auditory-Verbal Learning Test.
• Associations between HPOA and various variables were analyzed.

Main Results:

• 18 individuals (14% of the sample) met the criteria for HPOA.
• HPOA participants were, on average, younger and had higher educational attainment than standard performance older adults (SPOA).
• Multivariate analysis revealed that younger age (OR=0.672) and lower Geriatric Depression Scale scores (OR=0.831) were significantly associated with HPOA.

Conclusions:

• This research identifies high-performance older adults (HPOA) within a low-education, oldest-old demographic for the first time.
• The findings support the existence of biological underpinnings for exceptional cognitive aging.
• A potential association between younger age, reduced depressive symptoms, and HPOA is suggested.
