Those taking care of the elderly may be interested to hear that using internet search engines could help to maintain the mental health of older people, according to the Alzheimer's Research Trust.
Timothy Parry, a spokesperson for the charity, commented that the activity exercises a range of mental processes, which could be good for the elderly in terms of preventing dementia.
His comments were made following research by Professor Gary Small at the University of California, Los Angeles, in which it was found that internet searches used up more brain function than reading.
Mr Parry said: "The idea that internet search carries a cognitive benefit adds to previous studies supporting a 'use it or lose it' theory."
However, he also stressed that more research needs to be carried out to be sure of any significant benefits.
In his opinion, leading a healthy lifestyle and eating a balanced diet are still the best proven defence against the onset of dementia in the elderly.
