Is it possible that psychiatric meds harmed my brain? If yes, how to assess it?

Hello everyone. I was misdiagnosed and took the following meds for 3 years: Sertraline, Lithium, Perphenazine, Quetiapine, Clonazepam, Propranolol, Fluoxetine, Flurazepam, Melatonin.

I still feel like something's off in my brain.

Could this combo have caused lasting brain damage?

And if so, how can I actually check for it? I've heard MRIs don't always show functional or structural damages made by meds.

P.S.

I've actually shared my full story including my complete med history and treatment journey - in my earlier posts. I won't repeat it all here to avoid overwhelming you, but if you're curious or feel like it might help provide context, I'd genuinely appreciate you taking a look. Thanks for your time andattention.
