June 11: Unique forms and components of autism spectrum

June 3, 2014

In the middle hour we shared our unique forms and components of autism spectrum (dis)order (ASD). The DSM 5 lists restricted, repetitive patterns of behavior  of which we need to have at least 2 of 4 to meet the criteria of ASD:

  1. Stereotyped or repetitive speech, motor movements or use of objects
  2. Excessive adherence to routines, ritualized patterns of behavior, excess resistance to change
  3. Highly restricted, fixated interests that are abnormal in intensity or focus
  4. Hyper or hypo-reactive to sensory input or unusual interest in sensory aspects of the environment

Tics are repetitive involuntary movements or speech but not all tics are related to ASD.

Tourette syndrome: is an inherited neuropsychiatric disorder with onset in childhood, characterized by multiple physical (motor) tics and at least one vocal (phonic) tic. Rarely do they exclaim obscene words or socially inappropriate and derogatory remarks (coprolalia). But this is not ASD.

Rett syndrome: patients have repetitive stereotyped hand movements, such as wringing and/or repeatedly putting hands into the mouth. This is a pervasive developmental disorder of women but not ASD.

We also discussed mania, obsessive compulsive behavior and attention deficit hyperactivity disorder and we were reminded that as persons on the autism spectrum many of us have these other tendencies but they are not diagnostic of ASD.
