How Loneliness Affects Our Health

For those of us who spend a fair amount of time around people who are health challenged the article below is obvious.
What I learned early into my work with HIV/AIDS patients is that many of them were suffering from lonliness, isolation and abandonment.
This realization was the main reason we helped various organizations create “Care Teams” that brought supportive people together to offer social support to teminally ill people. The occasional phone call, note, coffee, group meal, or a movie could make a huge difference in a persons journey. The ravages of AIDS has lessoned but the same specter of lonliness stands in the corner always ready to spring forward with darker thoughts.
Princess Diana said “The biggest disease today is the feeling of being unwanted. People need to be loved, without love, people die.”
One way we help combat this is by giving people rides to their doctor apppintments. Such a simple thing that eliminates so much stress.
The American Cancer Society, through their program Road to Recovery, offers free transportation to those wrestling with Cancers. There are no charges to the patients nor any reimbursement to us for our expenses. One of the ways we fund our participation is through public support, sale of our books and gifts through our project on Universal Giving.

“The potentially harmful effects of loneliness and social isolation on health and longevity, especially among older adults, are well established. For example, in 2013 I reported on research finding that lonliness can impair health  by raising levels of stress hormones and inflammation, which in turn can increase the risk of heart disease, arthritis, Type 2 diabetes, dementia and even suicide attempts.

Among older people who reported they felt left out, isolated or lacked companionship, the ability to perform daily activities like bathing, grooming and preparing meals declined and deaths increased over s six year study period relative to people who reported none of these feelings. Writing for The New York Times’s department The Upshot last December, Dr. Dhruv Khullar, a physician and researcher at Weill Cornell Medicine in New York, cited evidence for disrupted sleep, abnormal immune responses and accelerated cognitive decline among socially isolated individuals, which he called “a growing epidemic.”
As research moves forward on these topics, scientists are gaining a more refined understanding of the effects of loneliness and isolation on health. They are also looking into factors such as who is likely to be most seriously affected, and what kinds of interventions may reduce the associated risks.

There are some surprising findings. First, though equivalent in risk, loneliness and social isolation don’t necessarily go hand-in-hand, Julianne Holt-Lunstad and Timothy B. Smith, psychologist-researchers at Brigham Young University, have pointed out.

“Social isolation denotes few social connections or interactions, whereas loneliness involves the subjective perception of isolation — the discrepancy between one’s desired and actual level of social connection,” they wrote in the journal Heart last year.

In other words, people can be socially isolated and not feel lonely; they simply prefer a more hermitic existence. Likewise, people can feel lonely even when surrounded by lots of people, especially if the relationships are not emotionally rewarding. In fact, Dr. Carla Perissinotto and colleagues at the University of California at San Francisco reported in 2012 that most lonely individuals are married, live with others and are not clinically depressed.

“Being unmarried is a significant risk,” Dr. Holt-Lunstad said, “but not all marriages are happy ones. We have to consider the quality of relationships, not simply their existence or quantity.”

As Dr. Nancy J. Donovan, a geriatric psychiatrist and researcher in neurology at Brigham and Women’s Hospital in Boston, said in an interview, “There is a correlation between loneliness and social interaction, but not in everyone. It may be simplistic to suggest to people who are lonely that they should try to interact more with others.”

Perhaps equally surprising is the finding that older adults are not necessarily the loneliest among us. Although most studies of the effects of loneliness have looked only at older people, Dr. Holt-Lunstad, who with colleagues has analyzed 70 studies  encompassing 3.4 million people, said that the prevalence of loneliness peaks in adolescents and young adults, then again in the oldest old.

According to Louise Hawkley, senior research scientist at the National Opinion Research Center at the University of Chicago, “If anything, the intensity of loneliness decreases from young adulthood through middle age and doesn’t become intense again until the oldest old age.” Only 30 percent of older adults feel lonely fairly often, according to data from the National Social Life, Health and Aging Project.

“We found stronger risks for those under 65 than for those over 65,” Dr. Holt-Lunstad said. “Older adults should not be the sole focus of the effects of loneliness and social isolation. We need to address this for all ages.”

Furthermore, she said, while it is not certain whether loneliness or social isolation has the stronger effect on health and longevity, “if we recognize social connections as a fundamental human need, then we can’t discount the risks of being socially isolated even if people don’t feel lonely.”

Equally intriguing is a recent finding suggesting that loneliness may be a preclinical sign for Alzheimer’s disease. Using data from the Harvard Aging Brain Study of 79 cognitively normal adults living in the community, Dr. Donovan and colleagues found a link between the participants’ score on a three-question assessment for loneliness and the amount of amyloid in their brains. Amyloid accumulation is considered a main pathological sign of Alzheimer’s disease.

In this study, loneliness was not associated with the extent of people’s social network or social activity or even with their socioeconomic status. However, in another study of adults 50 and older, published earlier this year in the International Journal of Geriatric Psychiatry, Dr. Donovan and co-authors reported that loneliness was linked to worsening cognitive function over a 12-year period, whereas initially poor cognitive function did not lead to increased loneliness.

When the researchers examined their findings more closely, they discovered that depression, even relatively mild depression, had a greater effect than loneliness on the risk of cognitive decline.

“There is now strong evidence relating greater depressive symptoms to increased progression from normal cognition to mild cognitive impairment and from mild cognitive impairment to dementia,” Dr. Donovan and colleagues reported, citing their findings and those of others. They suggested that loneliness as well as low-grade and more serious depression may have similar pathological effects on the brain.

All of which raises the question of how loneliness and social isolation might be countered to help ward off cognitive decline and other adverse health effects.

Suggestions for lonely or socially isolated adults have included taking a class, getting a dog, doing volunteer work and joining a senior center. A British program, called Befriending, involves one-on-one companionship by a volunteer who meets regularly with a lonely person. While such programs may show modest improvement on measures of depression and anxiety, their long-term significance is unknown. In a study of 14 trails of befriending, no significant benefit overall was found on measures of depression, quality of life, degree of loneliness, self-esteem and well-being.

Another program called Listen, developed by Laurie Theeke at the School of Nursing at West Virginia University, is a form of cognitive behavioral therapy to counter loneliness. It entails five two-hour sessions of small groups of lonely people who explore what they want from relationships, their needs, thought patterns and behaviors.

It is doubtful, however, that such an approach would be practical on a scale large enough to meet the need for cognitive restructuring of lonely adults nationwide.”
