A new study reveals the neurobiological effects of social isolation in mice. Researchers report a neurochemical called tachykinin is overproduced during long term social isolation, leading to increased aggression and fear.
According to researchers, social isolation and loneliness significantly increase the risk for premature death.
Socially isolated individuals may have an increased risk of physical inflammation in the body. Researchers found social isolation was associated with the presence of C-reactive protein and increased levels of glycoprotein fibrinogen. The link between social isolation and physical inflammation was more common in males.
Blood samples taken from older adults who experienced social isolation had higher levels of interleukin-6 and C-reactive protein, two biomarkers of inflammation.
Lonely people are 24 percent more likely to feel tired and have a harder time concentrating, a new study reports.
Active social connection is the strongest protective factor for depression, a new study reports. Additionally, reducing sedentary activities such as watching TV or taking a nap can also help lower depression risk.
Social isolation experienced during childhood has an impact on adult brain function and behavior. Following two weeks of social isolation immediately following weaning in male mice, researchers noticed a failure in activation of medial prefrontal cortex neurons projecting to the posterior paraventricular thalamus during social exposure in adulthood. Findings suggest medial prefrontal cortex neurons required for sociability are profoundly affected by social isolation at a young age.
