I don’t disagree with your theory at all. The brain has amazing neuroplasticity to repair faulty neural pathways. I believe the solution would be more holistic and would encompass tackling it from different angles. Think about it this way. If you rewire a faulty electrical circuit that’s burnt out, it will work again as designed, however, if the source of current is still pushing excessive electricity, then that new circuit will eventually faulter too. The root cause of the problem is the source of the excessive current. In our case, the dysregulated dopamine will always be there, firing hyperactively, because it’s at the root of our genetic makeup. Until scientists come up with a drug that fine tunes the balance of all these neurotransmitters involved in the speech motor networks, the issues will always be there.
