I read an interesting article
called “Loneliness can kill you.” The article looks at the neurological effects
of loneliness. This is a perspective that I had not thought that much about,
but the article and the research is interesting to those who are concerned
about loneliness in seniors. I have taken some of the ideas from this report
and hopefully, you find them interesting as well.
Among the many consequences
of loneliness on body and mind, the lack of social contact encourages drug
compensation and substance-use behaviour, such as alcoholism.
As people grow older, the social network typically becomes smaller – naturally diminishing the cognitive
stimulation through frequent and intense social interaction daily, thus
potentially reducing the neural reserve. Over the past century, the average
human lifespan in developed nations has increased by nearly three decades.
However, older people are also reported to show a decline in their capacity to
take other people’s point of view, as demonstrated in three separate
mentalizing tasks.
These authors of these
studies showed that social cognition deficits were related to decreased neural
activity responses. This capacity is likely to be particularly important when seniors
are thinking about other people who are not physically present – where social
cues such as facial expressions, mimics, and gestures are missing.
Both limited social
stimulation and weakening social reflection capacities relate to the sense of
loneliness in complex and important ways. Once lonely, bias for negative
information processing of cues from others hinders social rehabilitation in a
downward cycle. Many recent studies have corroborated the evidence that
feelings of loneliness escalate the risk of certain neurological diseases in
later life, especially Alzheimer’s disease.
We are social creatures.
Social interplay and cooperation have fuelled the rapid ascent of human culture
and civilization. However, we struggle when forced to live in isolation. The
expansion of loneliness has accelerated in the past decade. As one consequence,
the UK has launched the ‘Campaign to End Loneliness’ – a network of over 600
national, regional, and local organizations that aim to create the right
conditions for reducing loneliness in later life. Such efforts speak to the
growing public recognition and political will to confront this evolving
societal challenge. These concerns are likely to be exacerbated if there are
prolonged periods of social isolation imposed by national policy responses to
extraordinary crises such as COVID-19.
