Ask HN: How to restore cognition after years of trauma? I feel slow and dumb

From impaired long-term and working memory, clarity of thought, mental agility, to executive function, it feels like the depression and anxiety caused by trauma have completely blunted my mind to a debilitating degree. Acquiring, integrating, and productively applying information is an enormous challenge. In meetings, I feel like a mental sloth. I've tried a variety of antidepressants, psychedelics, and supplements, to no avail. Talk therapy has done little.

Has anyone been able to cognitively recover?
