<p>Schizoid personality disorder is characterized by a lack of interest in social relationships. However, with asperger syndrome, it's a limited empathy and understanding of other's situations. In other words, asperger syndrome deals with the inability to empathize while schizoid personality disorder deals with apathy toward other's emotions. Additionally, people with apserger syndrome tend to be less withdrawn than people with schizoid personality disorder. People who have asperger syndrome show repetitive behavior and interests, while schizoid personality disorder does not show this fixation toward repetitive behavior. Asperger syndrome is probably genetically linked somehow and is placed on the autism spectrum. However, schizoid personality disorder is not on the autism spectrum. I hope this response helped!</p>

<p>Schizoid Personality Disorder has nothing to do with psychosis.  A personality disorder is an enduring pattern of inner experience and behavior that deviates from the norm of the individual’s culture. The pattern is seen in two or more of the following areas: cognition; affect; interpersonal functioning; or impulse control. The enduring pattern is inflexible and pervasive across a broad range of personal and social situations. It typically leads to significant distress or impairment in social, work or other areas of functioning. The pattern is stable and of long duration and its onset can be traced back to early adulthood or adolescence.</p>

<p>It is difficult to distinguish between these two because tests and criteria are not perfect. Still, one is a form of autism, one is related to schizophrenia, so they should be different. I would look at autistic traits: tendency to see patterns, interest in numbers, inability to read emotions. If these are normal, then probably it is not asperger or any form of autism. As for schizoid personality disorder, there is a question if we are dealing with a disorder or a personality type. If it is not damaging to the quality of life of the person or others, it should not be evaluated as a disorder. There is an introvert personality type which resembles schizoid and is connected with many difficulties in life, but is still not a personality disorder. So make these three distinctions, separate autistic spectrum by its specific signs, then disorder by evaluating if is counts as a disorder (to be treated). If not, it is simply a possibly rare personality type. </p>

There is a good discussion of the issue at Scott Barry Kaufman A Call for New measures for Asperger's and Schizotypy, Scientific American, Aug 17. 2011. While is is of schizotypy, not schizoid, the problem is similar. In my answer I do not have good sources to refer to. Assuming that diagnostics criteria, like DSM IV 299.80 are filled for asperger and also schizoid criteria are filled, which can be so, then I would look for
