A neurosurgeon from the Université de Sherbrooke examines scientific data on the impact of digital technologies on young people's brains, in the context of Quebec's recent ban on cell phones in classrooms.
Neuroplasticity, the Key to Understanding
The brain constantly changes based on environment and experiences, a phenomenon called neuroplasticity. This capacity peaks during childhood, then gradually declines. Disruptions occurring at a young age therefore have more pronounced and lasting impacts.
Observed Effects in Studies
Scientific literature documents several associations between intensive screen use and brain development:
- Delays in language and reading development, accompanied by structural changes in brain white matter in intensively exposed children.
- A correlation between prolonged use (more than three hours a day) and the appearance of ADHD symptoms, observed in all age groups.
- An alteration of the central executive network, responsible for concentration and cognitive task management.
- A decrease in social and empathic skills, as well as a feeling of social isolation despite hyperconnection.
Since 2019, the WHO has recommended less than one hour of screen time per day for children under five years old.
