Neuropsychological Testing to Define Normal Cognitive Limits in Non-Institutionalized Adults Aged 80 and Older

What this Trial Is About

Researchers are evaluating cognitive performance in the oldest-old population, those aged 80 years and above, as current neuropsychological tests are not well adapted for this age group. This observational study aims to establish normal limits for 18 neuropsychological tests to improve diagnostic evaluations for this population. The research is sponsored by Consorci Sanitari de lAlt Peneds i Garraf and involves subjects without cognitive-affecting pathologies. The study will include 120 non-institutionalized participants aged 80 or older from the Comarca del Garraf area, divided into four age groups 80-84, 85-89, 90-94, and 95 or more. Participants will undergo 18 neuropsychological tests typically used in memory clinics. Test results will be adjusted for age and education level using linear regression, and normal limits will be defined by percentiles. Participants will be evaluated at a Memory Clinic Unit after enrollment, where cognitive performance will be assessed in about 60 minutes. Researchers will collect data through these tests to define normal cognitive function ranges for this age group. The study excludes individuals with certain mental illnesses, central nervous system diseases, severe sensory deficits, or dementia. Participation involves attending scheduled assessments and cooperating with test procedures until study completion in March 2026.
