American researchers proved that the feeling of loneliness, causing an extremely negative impact on the mental state of the person and in the extreme can lead to deep depression and even suicide attempts, many people have laid at the genetic level.
To such conclusion the Californian scientists from the University of San Diego published data in the journal Neuropsychopharmacology. The researchers found a correlation between loneliness and genetics. They focused on the sensations chasing a man all my life, and not arising at certain times due to varying circumstances, that is, it was determined that the development of depression are not always influenced by social factors and environmental conditions.
During the experiments, there were involved 10 760 volunteers aged 50 years and older. And, according to the study’s author, Professor Abraham Palmer,
“We found out that the genetic risk of loneliness is associated with depressive symptoms and neuroticism. Often two people with approximately the same size family and social circle one person symptoms of chronic loneliness, and the second — no. This is a genetic predisposition to loneliness, is activated under certain circumstances, some approximately equal socially of the people.”
It is worth saying that the conclusion from the experiment is the conclusion that genetic factors in 37-55% of cases are caused by the single.
