In Fuzhou, Fujian Province, a 25-year-old woman has reported an alarming decline in her memory and cognitive function, which she attributes to her excessive smartphone use. Spending over ten hours a day on her device, she has experienced increasing forgetfulness over the past six months. In severe instances, she has found herself unable to recall which floor she lives on. Doctors have diagnosed her with what they refer to as “digital dementia.”
According to a report from local sources, the young woman, identified as Ms. Wang, works in online sales. Her job requires constant communication with clients and managing various tasks through her smartphone. After work, she indulges in binge-watching short videos and dramas, further contributing to her already excessive screen time.
Initially, Ms. Wang brushed off the signs of cognitive decline, believing they were merely a consequence of a busy work life. However, as her forgetfulness escalated, the situation became more concerning. She frequently experienced lapses in memory, often forgetting what she intended to say mid-conversation. Additionally, she began to forget simple information, such as her own address, leaving her anxious and confused enough to seek medical advice.
Dr. Lin Xikang, the head of the neurology department at a rehabilitation hospital in Fujian, conducted tests and found a notable reduction in both Ms. Wang’s memory and attention span. Although other health assessments yielded normal results, Dr. Lin concluded that her cognitive decline was linked to her lifestyle, giving rise to the term “digital dementia,” colloquially known as “smartphone dementia.”
Dr. Lin elaborated on this diagnosis, explaining that “smartphone dementia” refers to a condition where the brain becomes “lazy” due to an over-reliance on digital devices. This condition does not equate to true dementia but manifests through diminished memory, scattered attention, and reduced communication abilities.
Previous reports from the Ningbo Evening News highlighted concerns raised by Dr. Li Guangxue, an associate chief physician in the pediatric and adolescent psychology department at the affiliated hospital of Ningbo University. Dr. Li pointed out that excessive smartphone usage encroaches on time dedicated to activities such as reading, deep thinking, and face-to-face interactions—activities that are essential for enhancing memory and logical reasoning. The fragmented nature of information exchange on smartphones can disrupt the consolidation and formation of memory.
In light of these findings, Dr. Lin recommended several strategies for mitigating the adverse effects of smartphone use. He advised reducing aimless scrolling and encouraged proactive memorization of tasks. When faced with simple questions, he suggested thinking independently before resorting to search engines for answers. Additionally, he emphasized the importance of engaging in physical exercise, reading, and setting boundaries by avoiding phone usage an hour before bed and not bringing devices into the bedroom.
The situation has sparked discussions among internet users who reflect on their own smartphone habits and experiences of forgetfulness. Many shared their own stories, with one individual noting their tendency to walk from the kitchen to the living room only to forget what they intended to retrieve from the refrigerator, often needing to stand and think for a moment.
Another user commented on frequently forgetting tasks they meant to accomplish shortly after leaving home, like whether they remembered to shut the door, particularly after a visit to the local supermarket where they couldn’t recall the items they planned to buy.
Concerns about the addictive nature of short video content emerged in the conversations as well, with some expressing worry that “short video addiction” is likely to increase, further contributing to cognitive issues among smartphone users.
This alarming case serves as a vital reminder of the potential cognitive consequences associated with excessive digital device dependence, urging individuals to assess their technology habits and prioritize their mental well-being.
