The brain imbalance narrative really is a double-edged sword.
On the one hand, it can help people understand that a condition is real and not imagined, especially other than the sufferer. "Look at this brain scan, it looks different from a healthy person's" is quite tangible and convincing.
On the other hand, it can lead to a sense of helplessness, and notions that because there's a physical element to the mental illness, it's a permanent disability, or to be exclusively treated with pills and injections. That just doesn't follow. Sometimes it's true, but in many cases, lifestyle interventions can help, talk therapy can help.
That's just your projection. A proper neurological diagnosis can absolutely help a patient find a viable path to recovery, as well as enable them to find support groups.
And not every neurological disorder is fixable. And the question of whether this is "sometimes" or "in many cases" is still in the air, unless you can provide solid citations proving otherwise. So there is no need for this kind of judgement.
I'm addressing the words you wrote, mainly this idea that learned helplessness is a significant concern when diagnosing chemical imbalances. Learned helplessness is tangential to a proper diagnosis, there is still CBT and other techniques for developing coping mechanisms around mental health issues, but those cannot be utilized without first receiving a diagnosis.
For example, in the case of ADHD, it s clear that patients have a reduced dopamine receptor count. It's not just a chemical imbalance, it's structural. Medication is the only effective solution for severe cases, and the result is night and day. Knowing this helps me make better decisions around my diagnosis, and also alleviates the great shame and anxiety that come hand in hand with ADHD.
I don't wish to devolve into an argument and I apologize if my initial comment was too aggressive.
