Digital technology has become an essential part of modern life, transforming how individuals learn, communicate, and process information. However, its excessive and unregulated use has raised growing concerns about cognitive health. This paper examines the key causes, effects and preventive strategies related to digital dementia, with a focus on children and adolescents. The findings indicate that early exposure to screens, excessive screen time, digital amnesia, multitasking, and digital addiction contribute significantly to this condition. These behaviours reduce cognitive efforts, weaken memory retention, and limit deep information processing. This study shows that excessive digital engagement disrupts learning, attention, and sleep patterns, while also contributing to emotional instability, social isolation, and reduced psychological well-being. Continuous exposure to digital stimuli increases dependence on external memory systems, resulting in cognitive overload and mental fatigue. Preventive strategies such as digital detox, mindful technology use, cognitive engagement, physical activity, proper sleep hygiene, social interaction, parental guidance and digital literacy education can help to mitigate these effects. In conclusion, it highlights the need for a balanced approach to technology use, emphasising moderation and awareness to preserve cognitive integrity and ensure long-term well-being.
