What was done
The author synthesized literature on nonpathological neuropsychological aging, summarizing theoretical models (speed-of-processing, common cause, and frontal aging hypotheses), cognitive reserve, neuroplasticity, and implications for psychiatric nursing practice.
What was found
No quantitative findings or numbers were reported in the abstract. The review qualitatively describes normal age-related declines in executive functioning, processing speed, memory, language, and psychomotor ability, alongside increases in vocabulary and crystallized intelligence.
Why it matters
It provides clinicians and psychiatric nurses with a foundational framework to distinguish normal cognitive changes from pathological decline and to encourage interventions supporting positive neuroplasticity.
Limits
As a narrative review, it lacks primary empirical data, quantitative effect estimates, and systematic literature search methodology. Sample sizes and study selection criteria were not reported in the abstract.
