Although research linking internet use to resistance to dementia does build on earlier findings, a healthcare charity has said the theory remains unproven.
Timothy Parry, a spokesperson for the Alzheimer’s Research Trust, said maintaining a healthy diet and regular exercise offer the most compelling evidence for slowing the onset of dementia.
Researchers from the University of California recently revealed that browsing on the internet could be a more effective way of keeping the brain active than reading.
Responding to the findings, Mr Parry said the study added to previous work supporting a "use it or lose it" theory.
He added that further research would need to be done before more detailed guidance could be offered.
The trust explains that dementia occurs when nerve cells in the brain deteriorate and die, while two proteins – amyloid plaques and tau tangles – begin to build up.
