New research suggests children may inherit brain traits from their anxious parents that make them susceptible to the same mental health condition.
Patterns of anxiety in families have long been observed by psychologists.
But, most research suggests that the similarities are due more to ‘nurture’ than genetic ‘nature.’
Meanwhile, a new examination of brain structures in anxious families of monkeys was conducted by the University of Wisconsin.
It identified at least 1 inherited brain circuit that plays an important role in the development of anxiety, according to Daily Mail.
They found anxious parents and their children shared inherited connections.
And, uncommonly close connections between brain parts that generate a fear response.
What became clear for mental health conditions is most develop through a combination of genetic and environmental factors.
Dr Fox of the University of California and his collaborators at University of Wisconsin decided to look for the brain structures that might distinguish young Rhesus monkey’s temperament from others.
He and his team estimate that the paralyzing shyness and ‘anxiety temperaments’ of the baby monkeys were about 30% inherited from their parents.
Furthermore, he cautions that this doesn’t mean they have found the root of all anxiety, or even the root of some anxiety.
