So imma explain some shit maybe poorly with what’s been happening in the psychiatric world.
Recently some huge studies have been published showing that what’s really going on in depression or anxiety isn’t neurotransmitter related it’s synapse related. Let me explain. As you go from being a baby to being 25 years old your brain goes from roughly 200M neurons to 100M neurons. Tf how do you not get stupider?? Well bitches it’s because of something called synaptic pruning. This reinforces the good synapses and eliminates useless synapses/neurons. Okay with all that being said for every neuron in your brain you have ~1000 synapses if you’re healthy. In depression or anxiety you have ~500. So they’ve found by stimulating synapses regeneration you can effectively treat depression from its root biological cause. A drug called Auvelity which is extremely new does this and it’s fucking amazingly effective. I’m talking like a week until you’re feeling better.
Now with all that being said, I’m betting the reason these psychedelics work as treatment is because they stimulate axonal regeneration. But they have the side effect of tripping tf out which can backfire and cause retraumatization.
I hope this makes sense or is cool to others, because it’s fucking awesome to me. Tons of people are about to get waaaaay better mentally because of this research.
Just to add to your point: in PTSD your brain will prioritize certain synapses over others that may help you survive through the trauma, but will result in a continued focus on the trauma after the event has passed. So those ~500 synapses in depressive PTSD aren't just lower than a healthy brain, but they're also the wrong synapses for your current situation. Psychedelics can help you develop new synapses that are more relevant to your current life. As someone who experienced this therapy, it's amazing how quickly it can happen, too. It's a total game changer and should be available to anyone who wants to try it.
