Digital dementia is a newer term being used by clinicians, and while it is not an official medical diagnosis, it is becoming more widely discussed. The idea originated in South Korea, where clinicians noticed more young people showing signs of memory and attention decline linked to heavy phone and social media use.
It refers to a pattern where constant screen exposure disrupts cognitive functions that normally develop through real-world interaction. These early reports describe problems such as forgetfulness, difficulty focusing, and an overall reduction in attention span.
