For those who have had a relationship with anxiety, even temporarily, it may seem surprising how others manage to live their lives so calmly. Why are some people protected while others are more likely to experience it? As with most aspects of our behavior, genetics as well as environmental pressures and lifestyle choices Science also has an influence. Thankfully, with a deeper understanding of how they interact, we can find new ways to minimize the problem.
Let’s start with your genes. Research shows that approximately 30 percent of the variation in generalized anxiety disorder in the general population is due to Caused by genetics. This is not due to any particular gene, but rather to a large number of interacting genetic factors.
For some people, it may be a gene related to the hormone serotonin, which carries messages to the brain. A study of marmosets found that the level of anxiety the animals perceived Gene responsible for protein that removes serotonin An area of the brain called the amygdala processes memories associated with fear. When serotonin was blocked from entering cells in the amygdala, the animals’ anxiety appeared to decrease.
This suggests that some people may have a genetic predisposition to absorb too much serotonin into cells in this area. As a result, less serotonin passes between neurons, disrupting the messages that help us…
