Statistics are variable, however, right now statistics in South Africa elude to a 1:88 incidence. The incidence of Autism Spectrum Disorder seems to be increasing rapidly. Although the new DSM diagnosis does not indicate treatment for Autism, it does provide diagnostic guidelines that enable the identification of the disorder early on in order for a prompt optimisation plan to be devised. Where developmental delays are concerned, early intervention is crucial.
The DSM V (Diagnostic and Statistical Manual), fifth edition, published in 2013 by the American Psychiatric Association, is the manual used by clinicians to diagnose psychiatric disease, including Autism. The DSM V classifies Autism as Autism Spectrum Disorder with 3 levels of severity. The criteria for the diagnosis of Autism Spectrum Disorder are categorised as follows and all criteria must be met:
Social and communication deficits *(all listed symptoms)
Repetitive behaviours (at least 3 out of 4 listed symptoms)
Paediatric Autoimmune Neuropsychiatric Disorders associated with Streptococcus (PANDAS) present as an acute onset of Obsessive Compulsive Disorder (OCD) in children.
Research led by Susan Swedo resulted in a publication in the American Journal of Psychiatry in 1998 (Swedo, Leonard, Garvey, Mittleman, Allen, et al. Pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections: clinical description of the first 50 cases. Am J Psychiatry 155: 264-271)
There are 5 criteria for the diagnosis of PANDAS:
Treatment involves immune regulation and antibiotic prophylaxis. Further work has led to the development of a concept, called Pediatric Acute-Onset Neuropsychiatric Syndrome (PANS) with a more acute onset of symptoms and not related to any particular infection.
The criteria for PANS would include:
Abrupt, dramatic onset of Obsessive-Compulsive Disorder or severely restricted food intake
Concurrent presence of additional neuropsychiatric symptoms, with similarly severe and acute onset, from at least two of the following seven categories (see text for full description):
Note: The diagnostic work-up of patients suspected of PANS must be comprehensive enough to rule out these and other relevant disorders. The nature of the co-occurring symptoms will dictate the necessary assessments, which may include an MRI scan, lumbar puncture, electroencephalogram or other diagnostic tests.
