    Is Schizoid personality disorder "Asperger/Autism"?

    "Schizoid personality disorder
    People with SPD are seen as aloof, cold and indifferent, which causes some social problems. Most individuals diagnosed with SPD have difficulty establishing personal relationships or expressing their feelings in a meaningful way, and may remain passive in the face of unfavorable situations. Their communication with other people at times may be indifferent and concise. Because of their lack of communication with other people, those who are diagnosed with SPD are not able to have a reflection of themselves and how well they get along with others. The reflection is important so they can be more aware of themselves and their own actions in social surroundings."

    "Autism"

    Autism is a disorder of neural development characterized by impaired social interaction and communication, and by restricted and repetitive behavior. These signs all begin before a child is three years old.[1] Autism affects information processing in the brain by altering how nerve cells and their synapses connect and organize; how this occurs is not well understood.[2] It is one of three recognized disorders in the autism spectrum (ASDs), the other two being Asperger syndrome, which lacks delays in cognitive development and language, and Pervasive Developmental Disorder-Not Otherwise Specified (commonly abbreviated as PDD-NOS), which is diagnosed when the full set of criteria for autism or Asperger syndrome are not met.[3]

    No, it is not, and there are fMRI scans to show that it has a distinct DMN signature, even in asymptomatic relatives. The symptoms are very different in the experience of the patient, and the prognosis is different.

    In mentioning asymptomatic relatives, would this apply to a spectrum? Are there similarities?

    No, it just seems to be a peculiarity of schizophrenia, schizophreniform disorders and schizoid personality disorder. Especially first order relatives will be appparantly asymptomatic, but fMRI shows some similar activity in their Default Mode Network. There was an excellent study which touched on this, out of Harvard, in 2009... I'll see if I can find it.
