Study Finds Digital Technology Use Reduces Cognitive Decline in Older Adults
A meta-analysis of over 411,000 participants challenges the 'digital dementia' hypothesis, showing technology use may protect brain health in later life.
- A meta-analysis of 57 studies, published in *Nature Human Behaviour*, found a 58% lower risk of cognitive decline among older adults who regularly use digital technology.
- The study refutes the 'digital dementia' hypothesis, which suggested that lifetime technology use weakens cognitive abilities, instead showing potential cognitive benefits.
- The protective effects of technology use were consistent across studies, even after controlling for factors such as age, education, income, health, and lifestyle.
- Researchers propose that digital technology fosters cognitive resilience by promoting memory, organization, and social engagement, though the exact mechanisms remain uncertain.
- Experts emphasize that while moderate technology use appears beneficial, excessive use, particularly of social media, may yield inconsistent or negative effects.
