Loneliness is often linked to Physical and Mental health. But now a recent study says that this Loneliness is partially due to genetics. Genetic risk for loneliness is also associated with neuroticism -- long-term negative emotional state -- and depressive symptoms, said the study published in the journal Neuropsychopharmacology.
Abraham Palmer, Professor of Psychiatry at University of California - San Diego School of Medicine in the US said, "For two people with the same number of close friends and family, one might see their social structure as adequate while the other doesn't. And that's what we mean by 'genetic predisposition to loneliness' -- we want to know why, genetically speaking, one person is more likely than another to feel lonely, even in the same situation."
The researchers also determined that loneliness tends to be co—inherited with neuroticism and a scale of depressive symptoms. Right now team works to find the right Genetic predictor. This will give a specific genetic variation that would allow researchers to gain additional insights. This may also help the researches to find the molecular mechanisms.
