A recent interview last month on crime time again with James Fallon on relation to sociopathy and given even more information if you have not seen it already. enjoy,
These might be out of place but ill try to hit main points. 3rd trimester for a pregnecy for a person like Fallon who has all these alleles, has there brain flooded with seritonin, desensitizing the amygdalas, prefrontalobe and other random areas. People often mistake Malignant Narcissists with ASPD as Sociopaths, for example: Manhunter movie's hannibal is a sociopath while the later ones in the 90's played by Hopkins show more of a malignant narc with ASPD on drugs. Main point is sociopaths are smooth, less uncanny or creepy to notice. Fallon had some weird period in his late teens were he had some sort of severe depression for some reason, not sure if it was seritonin related or not. Fallon had extreme OCD in his early teens were he would make up sins to be able to go to confession because he craved that clensing sensation. He had lots of random panic attacks at night in his teen years as well, not anxiety relate apparently.
I think that mainly sums up for that episode.
