Yes and no, but to my understanding it's actually no. They are both lumped together, although the person who "wrote the book" on sociopathy, makes statements about it, which counter diagnostic criteria for antisocial personality disorder.
Literature on sociopathy directly indicates a lack of emotional depth as part of the disorder, and while it is implied with antisocial personality disorder, it's not in the diagnostic criteria, and is not a requirement.
Also, literature on sociopathy indicates a person can contract sociopathy later in life, while one of the criteria for antisocial personality disorder is that this behavior was also present during childhood, in the form of "conduct disorder".
I fit the criteria for antisocial personality disorder, but I do not feel I fit the criteria for a sociopath.
I have
not been diagnosed with either, so I will
not state that I have either disorder.
It is my opinion that both disorders overlap a lot, but not perfectly.
It should be noted that technically sociopathy is not present in the DSM, although a reference to it is in the entry for Antisocial Personality Disorder.
