Question on psych meds effecting brain function and capacity

I originally posted this question in the bipolar forum, but I realize I should of posted it here. So my question is does meds like lithium and seroquel or any psych med effect your brain capacity or functioning in any negative way. I seem to be having a lot of dull brain moments and brain fog, also I find it hard to think critically and creativity. It has caused me to have confidence issues and is hindering me in a way that I know I can overcome but is just making it a bit difficult for me. Any input would be great thanks!

In my experience psych meds do cause cognitive impairment. This is especially true of benzos and the more sedating meds.
