^ There have actually been studies done that show that MDMA has little to no effect on cognition. So memory, writing skills and all that should be mostly unaffected.
I have it on a good source that this isn't true. As far as memory goes, a neurotoxic dose of MD, like chronic weed, (damages at least) both the striatum and the hippocampus, the latter which should repair themselves in the course of a few months. As far as language center goes, it is one of the few cognitive damages that takes a couple of years to heal - more if subject is/was a chronic weed smoker. I am currently on month 6 of my recovery and I have to say that I have experienced both of these damages. My first couple months my short term memory was TERRIBLE, but it has since come back. My language abilities are still not up to par. It is difficult for me to read, I have to get into what I'm reading for it to "sink in". Speaking, I sometimes stop in the middle of a sentence to search for the next word I am going to use - again. something that chronic marijuana users experience. Time, however heals all wounds, I guess. And to echo Show, exercise is crucial to healing your brain. Shit sucks but you gotta pull through it - it only gets better from day one.
