eli5: why do we have panic attacks?

223 views

I know this may be a dumb question, but i’ve always wondered what the biological reason for panic attacks was. Is it because our brains are tricked into going into fight or flight modes? If that’s the case then wouldn’t you just feel adrenaline? And I know i’m not speaking for everyone, but for myself at least- panic attacks do not feel like bursts of adrenaline. They feel like i’m having a heart attack and I can’t shake the scary feeling of impending doom :/

It’s an extremely basic brain signalling system that goes back hundreds of millions of years. It’s meant to preserve your life.

In most people and most animals that’s when it tends to activate. But animal brains have become complex enough where brains can rewire perception of what is and isn’t important, so you can end up with this pathway triggering for mostly useless reasons.
