The idea that too much screen time and digital dependence might harm our cognitive abilities-
often called“digital dementia(呆)”一has been debated since psychiatrist Manfred Spitzer
coined the term in 2012.Critics argue that outsourcing memory (like relying on smartphones for
contact details)and passive media consumption,such as endless scrolling,could weaken mental
sharpness.But is this really true,especially for older adults who have witnessed the digital revolution
firsthand
A major 2024 study published in Nature Human Behaviour analyzed data from over 411,000
adults aged 50 and above.Surprisingly,it found that regular use of computers,smartphones,and the
Internet was associated with a 58%lower risk of cognitive decline-a stronger protective effect than
even physical exercise or maintaining healthy blood pressure.
This doesn't mean technology directly prevents dementia,but it suggests that staying digitally
engaged may help keep the brain active.Learning new apps,resolving tech issues,and even online
socializing could function like mental workouts,strengthening cognitive resilience ()In
fact,technology aids instead of harming because it offers mental stimulation,enhances social
connection,and boosts independence via problem-solving.
While this study is a relief,not all tech use is equal in its effects.Passive activities,like binge
-watching TV,may not offer the same benefits as interactive tasks,such as video calls or online
learning.Additionally,too much screen time in younger people has been linked to attention problems
and poor sleep-which could have long-term effects.
As AI and brain-computer interfaces advance,older adults may gain even more tools to support
cognition,from memory aids to virtual social companions.However,balance remains key.The best
approach Use technology actively -learn,connect,and problem-solve-rather than just
consume.
For now,older adults shouldn't fear "digital dementia."Instead,thoughtful tech use might be
one of the best ways to keep their minds sharp in the digital age.
32.What does the 2024 study reveal about "digital dementia"compared with the popular idea
A.It draws a contrary conclusion.

33.Why can active digital use reduce the risk of cognitive decline
A.It can prolong our life.
B.It can activate our brain.
C.It can solve tricky issues.
D.It can enhance our ability.
34.What does paragraph 4 mainly talk about
A.Reliability of the new study.
B.Negative effects on the young.
C.Downsides of passive tech use.
D.Contrast between two tech uses.
35.What does the author suggest the elderly do in the last two paragraphs
A.Relieve their fear quickly.
B.Get more tools to sharpen cognition.
C.Consume technology simply.
D.Make considered use of modern tech.
