Seems like research you would probably need to take with a grain of salt. While being socially isolated obviously isn't good for anyone I'd sceptical if someone who is isolated yet is active, eats well and keeps their minds active would show similar results. My guess would be those that are socially isolated are less likely to be physically active, less likely to eat well and less likely to engage in activities that stimulate their minds. I'm thinking of people like my Gran who in last decade of her life after the passing of her husband did little more than watch TV and walk to shop once a week. People who live like this noticeably change. I've seen it in myself during periods of depression and social isolation. I'm not sure it's the isolation that does the damage, more everything else that often goes along with people who are living isolated.
