Association Between Laptop use and Cognitive Functioning: An Observational Study.

Abstract

Introduction: Cognitive decline and dementia are major global health concerns. Pursuant to the premise behind the concept of "computer-related dementia," an excessive use of internet-connected gadgets and online resources might accelerate the progression of dementia in its early stages and result in cognitive deficits such as short concentration as well as memory span.
Objective: This study explores the association between prolonged computer use and cognitive decline, emphasizing the potential risks of “computer-related dementia.”
Methods: An online observational survey was conducted among 1004 participants from Uttar Pradesh and Uttarakhand between January and March 2025, in compliance with the Declaration of Helsinki and reported in accordance with the CHERRIES (checklists for reporting results of internet E-surveys) guidelines. Results: Participants included 64.4% males, 30.05% females, and 5% transgender individuals, with most (59.6%) aged 15–25 years. Laptop usage varied: 48.7% did not use one, 29.1% used <1 hour/day, 17.6% used 3–5 hours/day, and 4.7% used >8 hours/day. Statistical analysis (F = 3.501, p = 0.15) revealed significant group differences, suggesting a link between extended screen time and impaired cognitive functioning.
Conclusion: As digital dependency grows; clinical pharmacists play a vital role in promoting cognitive health and mitigating technology-related cognitive risks.
