Meditation could help combat loneliness in elderly
Washington, August 15 (ANI): A simple meditation program lasting just eight weeks reduces loneliness in older adults, a new study has revealed.
Further, knowing that loneliness is associated with an increase in the activity of inflammation-related genes that can promote a variety of diseases, the researchers at UCLA examined gene expression and found that this same form of meditation significantly reduced expression of inflammatory genes.
In the new study, senior study author Steve Cole and his colleagues report that the two-month program of mindfulness-based stress reduction (MBSR), which teaches the mind to simply be attentive to the present and not dwell in the past or project into the future, successfully reduced the feelings of loneliness.
Remarkably, the researchers said, MBSR also altered the genes and protein markers of inflammation, including the inflammatory marker C-reactive protein (CRP) and a group of genes regulated by the transcription factor NF-kB. RP is a potent risk factor for heart disease, and NF-kB is a molecular signal that activates inflammation.
Inflammation is a natural component of the immune system and can help fight a wide variety of bodily insults, ranging from infections to a whack by a hammer. But chronic inflammation is now known to be a primary player in the pathology of many diseases and psychological disorders.
"Our work presents the first evidence showing that a psychological intervention that decreases loneliness also reduces pro-inflammatory gene expression," Cole said.
"If this is borne out by further research, MBSR could be a valuable tool to improve the quality of life for many elderly," he said.
In the study, 40 adults between the ages of 55 and 85 were randomly assigned to either a mindfulness meditation group or a control group that did not meditate.
All the participants were assessed at the beginning and the end of the study using an established loneliness scale. Blood samples were also collected at the beginning and end to measure gene expression and levels of inflammation.
The meditators attended weekly two-hour meetings in which they learned the techniques of mindfulness, including awareness and breathing techniques. They also practiced mindfulness meditation for 30 minutes each day at home and attended a single daylong retreat.
These MBSR participants self-reported a reduced sense of loneliness, while their blood tests showed a significant decrease in the expression of inflammation-related genes.
"While this was a small sample, the results were very encouraging," Dr. Michael Irwin, a professor of psychiatry at the Semel Institute for Neuroscience and Human Behaviour at UCLA, said.
"It adds to a growing body of research that is showing the positive benefits of a variety of meditative techniques, including tai chi and yoga," he added. (ANI)
