Digital dementia: How excessive screen time threatens memory

By Ahmet Taş | Wise News Press

ISTANBUL, TURKIYE — Clinical Psychologist Aleyna Damla Özcan warns that the excessive and unconscious use of digital technologies is leading to a condition known as "digital dementia," characterized by memory loss and impaired cognitive function.

As smartphones and tablets become inseparable from daily life, their uncontrolled use is increasingly linked to symptoms similar to early-stage dementia, particularly among children and adolescents. According to Özcan, a specialist at Moodist Psychiatry and Neurology Hospital, long-term screen exposure significantly increases the risk of developing cognitive impairments, as digital devices often provide information too effortlessly, bypassing deep mental processes.

Impact on brain structure and mental health

Excessive screen time does more than just cause forgetfulness; it may physically alter the brain. Özcan notes that studies have observed reductions in gray and white matter volume in individuals with high screen exposure, which can weaken the ability to form new memories and learn effectively. Furthermore, the blue light emitted from screens suppresses melatonin, disrupting sleep quality and further taxing cognitive reserves. Beyond cognitive decline, digital dementia is often accompanied by emotional instability, including increased stress levels and irritability.

Preventive measures and digital detox

To combat the onset of digital dementia, Özcan emphasizes the necessity of controlling digital consumption through a "Digital Detox". She recommends several key steps to maintain a healthy distance from digital devices:

• Daily screen time should be strictly limited to prevent cognitive overload.

  
  

• Specific hours should be established for digital device use to create a structured routine.

• Smartphones and tablets should be charged outside of the sleeping area to protect sleep hygiene.

Strengthening cognitive resilience

Beyond limiting technology use, engaging in activities that actively challenge the brain is crucial for strengthening cognitive reserves. Özcan suggests solving puzzles, reading books, learning new skills, and performing memory exercises without digital assistance. She also advises focusing on a single task rather than multitasking and turning off unnecessary notifications to reduce mental load and increase productivity. If individuals find it impossible to reduce their screen time despite these efforts, Özcan stresses that seeking professional psychotherapy is a vital step in managing the situation healthily.
