If you have an anxiety disorder, you can blame your parents using data from a new study. Although it won't be for the reasons you think.

A new study in The Journal of Neuroscience found that monkeys tend to pass on anxiety from generation-to-generation, meaning there's likely a genetic component to their anxiety. The scientists also believe this trait is likely passed from generation-to-generation in humans as well.

So if you suffer from anxiety, you probably got it from your parents' genes.

The researchers conducted stress tests on monkeys in a lab and found that certain parts of the brain lit up when doing so. They found similar brain responses to stress in previous generations of the monkeys, indicating a genetic component to their brain's response to stress. 

Since monkeys and humans are very similar at the genetic level, the researchers believe these results are probably true for us as well. This isn't to say that all stress and anxiety is genetic and there certainly are environmental factors as well. 

This study is particular important because it can help researchers in the future figure out how to address the causes for anxiety instead of attempting to simply focus on the symptoms of it.
