Rising Concern Over 'Digital Dementia' Linked to Excessive Screen Time

Clinical psychologist Aleyna Damla Özcan warns that uncontrolled, prolonged use of smartphones, tablets and the internet can trigger a condition she calls “digital dementia.” The syndrome is characterized by forgetfulness, difficulty focusing, impaired multitasking and overall weakening of cognitive functions, with children and adolescents especially vulnerable.

Research cited in the articles indicates that long‑term screen exposure may alter gray‑ and white‑matter volumes in the brain, reduce short‑term memory, and disrupt sleep by suppressing melatonin through blue‑light emission. A United States study found that people check their phone screens an average of 205 times a day—about 12 times per hour—leading to roughly 96 daily distractions.

Experts recommend limiting screen time, using digital‑wellbeing tools, reducing notifications, and establishing screen‑free periods to protect mental health and cognitive performance.
