Anyone have a scientific explanation for the OCD? I don’t mean why some people get it, I know that’s unknown, but I mean as in what happens to the brain during an attack or why we get stuck on obsessions and can’t react logically like most people would?

I learned at McLean that the neurobiological smoking gun is the Amygdala . It senses fear incorrectly.

Basically as I understand it, the wordless fear center of the brain "amygdala" misfires and sends out a signal for fear/terror with all the physical symptoms that go with that. Then, the thinking brain tries to come up with a reason why there is this wordless terror, since it doesn't like to think that emotions are random or without purpose. I don't think we know which one comes first though, the thought or the terror.

I’d love to know the answer too

??wow that makes sense. For me it’s defo the terror, and then I have my go to obsession. When I’m not anxious my obsession is silly!

I broke my obsession last night I had the better of it and the relief was tremendous, best feeling ever, I was laughing and smiling and I thought, right let’s live life! I was so excited and this morning,boom! Back to square one! Crazy!

Personally I think mine developed into the way it does from traumatic experiences regarding being trapped in an abusive household my whole life that never changes so my brain developed to obsess over the same old and things I already know, replaying them over again and digging more into it.

i can relate to that... somedays i'm king of the world and other days i'm being dragged through the mud. I just try to continue forward in my life despite my feelings. Keep doing my hobbies and chores etc.

yeah it helps me to think of my brain as just another organ, and that helps me have more self-compassion and forgiveness for these thoughts that I "have" (more accurately they're just thoughts that appear and have nothing to do with me or what I value).

Me too. My brain is definitely trying to replay a traumatic incident trying to find the meaning. I have a million times! And it’s never good enough. The same thoughts and feelings occur as that night fueling the anxiety fire and my brain thinks the same outcome will happen. It never does, ever, because it’s not logical. It truly is an obsession. I hope to finally break it someday but I wonder will I ever be able to?
