Scientists investigated whether online conversations could improve brain function in older adults experiencing social isolation.
The study (known as I-CONECT) included 186 adults aged 75 or older who were socially isolated. Some had normal brain function, while others had mild cognitive impairment.
Half the participants engaged in structured video chats four times a week for six months, followed by twice-weekly chats for another six months. The other half had brief weekly phone calls.
After the initial six months, those who frequently video chatted had better overall cognitive scores, especially those with mild cognitive impairment. Their attention-related brain networks were also stronger. Even those only receiving short phone calls saw emotional improvement.
Regular digital conversations could be an effective way to fight the negative mental effects of social isolation and potentially reduce the risk of dementia for older adults.
This research was conducted at Massachusetts General Hospital and published in the journal The Gerontologist.
