@leokitten I'm having trouble understanding your idea on how abilify works. As far as I understand it, you are saying that dopamine is very costly energetically to the brain so abilify has the dopamine hang around longer. It does this by blocking presynaptic autorecepters?
Remember too that the aripipirazole molecule itself is like a partial dopamine molecule and has instrinsic activity and binding affinities between 15-90% of endogenous dopamine depending on dopamine receptor type and brain area. So it’s not only affecting the flow of dopamine in synapses etc and where but it itself functions as a neurotransmitter.
Running the dopamine system of the brain appears to be an energy intensive process compared to other neurotransmitter systems and it’s has to create dopamine and put into vmat2 vesicles near ends of neurons, unpackage dopamine and push into the synapse, bind to pre and post synaptic receptors, perform neurotransmission, collect dopamine back into neuron, package into vmat2 or mao oxidize, etc etc very frequently compared to other neurotransmitter systems (it’s controlling all fine and gross muscle movements, arousal and desire, reward, etc, you get my drift your dopamine system is at the very center of what we are)
I think you are just looking at the synaptic neurotransmission part, but I’m guessing at some other points in the entire cycle reduced ATP and/or increased ROS generation due to cellular metabolism and mitochondrial dysfunction can driving overall dopamine system dysfunction too.
For example reduced ATP generation and increased ROS generation due to dysfunction of mitochondrial complex I is implicated in Parkinson’s disease.
