When you have a stress/anxiety response, three parts of your brain are involved. These are: Your brain stem – also known as your 'animal brain', 'reptilian brain' or 'survival brain' Your limbic system which includes your hypothalamus, hippocampus and amygdala – also known as your 'emotional brain'
During anxiety, it is likely that the right brain has temporarily taken over. The feelings are overwhelming, and without the full involvement of the left brain, the feelings won't necessarily make sense. A balance between the right and left are necessary to maintain normalcy.
Chronic stress and anxiety can lead to structural degeneration and decreased functionality of the hippocampus and the prefrontal cortex. This can increase the risk for psychiatric disorders, including depression and dementia.
Anxiety is what we feel when we are worried, tense or afraid – particularly about things that are about to happen, or which we think could happen in the future.

I say “not really” only because sometimes a person may come to the emergency room or doctor's office with anxiety or agitation.
One thing everyone who is having problems with anxiety has in common is that their brain is tricking them. It's telling them that they're in danger, when actually they're not. And it's tricking them into doing things that make it worse.
