I have poor memory when I am kinda depressesed
and good memory on elevated mood
and mania
and my intelligence , creativity etc also improves.
Doctor told me that I have Fluctuating mood and he gave me a Tetracyclic Antidepressant (Mirtazapine) and an antipsychotic Risperidone. Yes, I had psychosis . But now I am avoiding my doctor's advice and taking only antidepressant and my memory/cognition is improved. But I am very little mania type now.
