I've been looking up stuff on Google Scholar and it turns out that excessive stress hormones for too long damages the hippocampus, which is involved with memory. So, it makes sense that stress ==> memory problems. Studies done with people with PTSD (runaway stress reaction) and tumors that cause excessive secretion of stress hormones end up with the same impairment in verbal memory. So, were talking major stress levels here for that to happen (or else ASD folk have a lower threshold for such damage).
This is interesting (since I'm also having memory problems, age 42). But maybe it's not the hippocampus. Some research has shown people with autism have a less developed hippocampus. But newer research is showing something different. Maybe it's the amygdala:
Quote:
"There was a significant group difference in aging of left amygdala; controls, but not individuals with Asperger syndrome, had a significant age-related increase in volume (r = 0.486, P<0.01, and r = 0.007, P = 0.97, z = 1.995). There were no significant group differences in volume or age-related effects in hippocampus. Individuals with Asperger syndrome have significant differences from controls in bulk volume and aging of the amygdala."

http://www.ncbi.nlm.nih.gov/pubmed/21948742The amygdala is also involved in memory so that makes sense. What's more:
Quote:
"We found that amygdala volume correlates with the size and complexity of social networks in adult humans. An exploratory analysis of subcortical structures did not find strong evidence for similar relationships with any other structure, but there were associations between social network variables and cortical thickness in three cortical areas, two of them with amygdala connectivity. These findings indicate that the amygdala is important in social behavior."

Also, there's evidence the left amygdala is involved in the positive reinforcement mechanism of the brain. That might explain why many of us have such low self esteem and never feel like we're moving in the right direction. And why in my case no matter how much I'm rewarded and praised I still feel like a worthless piece of s**t that's just doing everything wrong.
Is modern research finally getting closer to understanding what causes Aspergers?
