Normative data for the Boston Naming Test and the Pyramids and Palm Trees Test in the elderly Spanish population

Area of Science:

• Neuropsychology
• Cognitive Aging
• Gerontology

Background:

• Normative data for cognitive tests are essential for accurate clinical assessment.
• Existing cognitive test norms may not adequately represent diverse elderly populations, such as Spanish speakers.
• Semantic memory and naming abilities are crucial cognitive functions affected by aging and dementia.

Purpose of the Study:

• To establish normative data for the Boston Naming Test (BNT), Semantic Fluency Test (Sem-Flu), and Pyramids and Palm Trees Test (PPT) in an elderly Spanish population.
• To investigate the influence of demographic factors like education and gender on these cognitive tests.
• To explore the relationship between naming and semantic memory performance in this cohort.

Main Methods:

• 121 Spanish-speaking seniors participated in the study.
• Participants completed the Boston Naming Test (BNT), Semantic Fluency Test (Sem-Flu), and Pyramids and Palm Trees Test (PPT).
• Statistical analyses were performed to determine mean scores, standard deviations, and the influence of education and gender.

Main Results:

• Mean scores were BNT: 49.6 (SD=5.6), PPT: 49.6 (SD=2.2), Sem-Flu: 16.9 (SD=4.9).
• Education significantly impacted all semantic memory tests (p < .01), and gender influenced the BNT.
• A significant positive association was observed between naming and semantic memory test performance (p < .01).

Conclusions:

• The study successfully generated normative data for key naming and semantic memory tests in elderly Spanish speakers.
• These normative data are valuable for the accurate neuropsychological assessment of cognitive function in this demographic.
• The findings support the utility of these tests in identifying cognitive decline and dementia in Spanish-speaking elderly individuals.
