How bad can memory be with peri-menopause?

I'm 41 and started my peri-menopause around 37, possibly a little earlier. I smoked until late 30s so that's why I started so early I think.

I've had an 'ear infection' for 3 years now. I've been going to a Ear Nose Throat specialist and he sent me for a brain MRI in March but I've heard nothing since despite ringing and leaving messages requesting an update. It gives me headaches that make my brain feel hot.

My question is this: How bad did your memory get during or after peri-menopause? There are a few things over the last few months that I didn't just forget, I completely erased the memory and there's no recalling them. Normally (i believe) when we forget something, it can usually be recalled if someone tells you about it, but I've been told things and I still can't remember them at all.

I'm somewhat paranoid that it's not due to hormones but a brain tumour or something.

Unfortunately, going to a dr about this doesn't seem feasible right now. (No money, feels like paranoia anyway, kinda just need reassurance or advice from other women).
