Background: Aging has been defined as a persistent deterioration in the age-specific fitness components of an organism, attributed to internal physiological degeneration. Cognitive abilities, encompassing attention, memory, executive cognitive functions, language, and visuospatial capacities, are distinctive domains affected by aging. Numerous studies have documented measurable effects on these cognitive domains, indicating a discernible decline in their functionality with advancing age. Cognitive impairment often unfolds insidiously, remaining clinically silent for extended periods. Age, as a critical factor, exerts a notable influence on P300 measures. Result: Spearman rank correlation was calculated between age and P300 measures. In group 1A (age range of 10–20 years), we found a strong positive correlation between age and amplitude of P300 (r = 0.96, p < 0.001), while a weak correlation was found between latency and age. In group IB (age range: 21–40 years), a moderate negative correlation (r = − 0.43, p < 0.05) was found between age and amplitude of P300, while a strong positive correlation (r = 0.87, p < 0.001) was obtained between age and latency. In group 2A (age: 41–60 years), it was found that amplitude has a strong negative correlation (r = − 0.97, p < 0.001) with age, while latency has a strong positive correlation (r = 0.89, p < 0.001). In group 2B (age: 61–80 years), it was found that amplitude has a strong negative correlation (r = − 0.93, p < 0.001) with age, while latency has a strong positive correlation (r = 0.95, p < 0.001). Conclusion: In this study, it is concluded that amplitude of P300 decreases and latency increases with increasing age. [ABSTRACT FROM AUTHOR] |
