The main contrast between Autistic Disorder and Asperger’s Disorder is severity. Those most unfortunate tend to suffer with autism. The main features of both disorders are impaired social relations, impaired social communication, and stereotyped/repetitive behaviors. While many readers may be thinking of those they know who meet these criteria, it is not likely your friends suffer with either disorder. Autism is a severe impairment leaving most sufferers institutionalized after adolescence. Most, but not all, autistic patients become aggressive after childhood. The aggression seldom has a precipitant; a root stimuli that escalated the frustration to violence. Most autistic patients have very noticeable impairments of cognition and language development. A huge difference between those who are classified as Asperger’s or Autistic Disorder is the normal cognitive and linguistic development of Asperger’s patients.
Both disorders suffer with social impairment, though at a different level of severity. There is difficulty using nonverbal (bodily) communication to regulate social interaction. Eye contact is poor or eerily constant, and facial expressions are bizarre and not appropriate to the situation. Bodily gestures are bizarre and inappropriate as well. Both disorders exhibit a lack of age appropriate peer relationships. It is rare that either disorder spontaneously desires to share their experiences for the enjoyment or interest of others. There is an aspect of poor emotional reciprocity, where one fails to note and respond appropriately to the emotional needs of others.
Many child and adolescent schizophrenic patients share some of the social impairment of the autistic spectrum disorders, but they rarely share the stereotyped and repetitive movements. These movements are bizarre and intense, such as hand flapping and twisting, finger flapping, and flipping objects. There are often whole body stereotyped movements; e.g., an autistic patient of mine constantly put his arms around his head. He sometimes twisted or grimaced while performing this wrapping of arms around his head. Once one is exposed to autistic movements, they are hard to mistake for nearly any other disorder. Asperger’s sufferers experience similar movements, but rarely so bizarre and intense as Autistic Disorders. I have witnessed many forms of neurological movement disorders over the last 20 years, and none mimic those of the autistic spectrum disorders.
There is an occasional diagnostic confusion with Obsessive-Compulsive Disorder. Both Asperger’s and autism share an intense preoccupation with routines and rituals. These restricted interests focus narrowly and to the exclusion of necessary routines one needs to accomplish each day. It is difficult to label this as something other than a compulsion, though the diagnostic criteria for the autistic spectrum disorders make no mention of obsessions. In my limited work with autistic patients, primarily while in training, every patient I observed suffered with severe obsessions. The significant difference I noted was that the in the O-C, the cognitive obsession was strongly linked to the compulsive behavior. For the autistic, the repetitive thoughts might result in nearly any behavior; related or not to the automatic repetitive thoughts.
While I have had to diagnose children with Autistic Disorder in institutions, I’ve never diagnosed someone with Asperger’s Disorder in my outpatient practice. It is not uncommon to be referred a new patient with a diagnostic question regarding Asperger’s, but none have met the published diagnostic criteria. Many people have difficulty with social relationships, and fortunately for them, it is rarely secondary to an autistic spectrum disorder. A hallmark of these disorders is the bizarre and nonfunctional stereotyped/repetitive movements. All the other symptoms overlap with other conditions.
In terms of treatment, most Autistic Disorders require institutionalization by mid-adolescence. Those that are not aggressive, typically with nearly normal cognition, may be kept within the community. Asperger’s Disorder is not generally treated on an inpatient basis. The typical treatment is social skills training; making the patient aware of behaviors that distance or offend others. These patients will never be socially comfortable or smooth, but the quality and success of their social interactions may be significantly improved.
