Regrets9995, It sounds like you are just dealing with one of the many symptoms that comes along with DP and DR. In the first 6 months or so, I felt like my memory was completely shot, and to some degree it still does, but is much better now a year and a half in.
Saying this, even when I was in the pits of hell with this thing, I had to remember large amounts of information and multiple studies for exams at uni. One exam required me to essentially recite 12 studies from memory and I managed to get a high grade despite my situation. It really does feel like our minds are truly messed up but you'll be surprised what you can do when you are given the chance, and time will certain show improvements for you, even if you did not recover 100%
Socrilus, there is some speculation and a number of studies showing that curcumin extract can have an impact on DHT levels. BUT this is curcumin extract not turmeric. Curcumin makes up about only 3% of turmeric by weight and even then has a very limited bioavailability unless combined with something like pepper. Curcumin makes for an effective anti-depressant treatment for MDD but otherwise it shouldn't really be used in extracted form. In fact, as a nutrition graduate, I always say to anyone that under most circumstances, that use of extracts or concentrations taken from whole foods are generally a bad idea. Unless there is a some sort of allergy or food intolerance to turmeric, it should be consumed daily, with it being one of the worlds healthiest foods.
I highly recommened those with a depression based LTC try implementing golden milk as part of their daily routine before they consider SSRIs
