Paediatric Acute-onset Neuropsychiatric Syndrome (PANDAS) misdiagnosed as autism: some implications

Credit: BBC Website 25 January 2019
The BBC website recently ran with an interesting story headed under the title: "Mother's appeal after boy diagnosed with autism when he just needed antibiotics." It was an interesting piece that drew attention once again to an increasingly important condition known as Paediatric Acute-onset Neuropsychiatric Syndrome (PANDAS) also called PANS.

Classically triggered by Streptococcal infections, PANDAS/PANS is typically characterised by quite an abrupt change in behaviour to include things like "clinically significant obsessions, compulsions and/or tics" alongside things like anxiety, sensory issues, aggression and a corresponding loss of academic abilities. Treatment is often multi-disciplinary; but in the most part intervention includes the use of various types of antibiotics clinically indicated to treat strep infections. This also follows a wider research-based thread suggesting that strep infections *might* have some important links to various neuropsychiatric conditions (see here).

The BBC piece specifically focused on how the young boy highlighted was "repeatedly diagnosed as having autism and severe anxiety" and how following a PANDAS diagnosis, and after just two days of antibiotic treatment, the mother of the young boy "felt like Jack was back." I'll also mention that the mum of Jack was herself a medic, a psychiatrist, and so was perhaps more attuned than most people about clinical diagnoses like autism and anxiety. It also emphasises how she kept on questioning...

Mention of the label autism in the BBC story got me thinking about quite a few things. Although still relatively sparse, there are some isolated reports in the peer-reviewed science literature observing that something like PANDAS/PANS can be "misdiagnosed as autism spectrum disorder" [1] in some circumstances. Such a notion complements some still emerging views that: (i) there may be many different routes to a diagnosis of autism (pertinent to the notion of 'the autisms'), (ii) autism is not universally an inborn genetic condition/state/diagnosis present from birth or early infancy, and (iii) autism for some people, is not necessarily a lifelong condition or label or state. Having discussed those views quite a bit on this blog (see here and see here and see here respectively) and noted some 'resistance' in some quarters to them, it is important that stories such as the one about Jack are continually highlighted. Not least because for him at least, his mother's determination and tenacity ultimately led to a new [accurate] diagnosis and subsequent treatment tailored to his particular circumstances. I daresay that other children (and even adults) who perhaps share Jack's clinical picture remain undiagnosed and untreated out there; something which represents a significant health inequality for them and their families. I might also add that the autism-anxiety diagnostic mix discussed in the BBC piece also complements the idea that the word 'comorbidity' may not be entirely accurate for the experience of [some] anxiety in the context of [some] autism (see here).

Jack's story begs the question: just how many people have been diagnosed with autism yet are 'suffering' with undiagnosed PANDAS/PANS? There's a research study there for someone brave enough there; alongside further study on whether elucidating the mechanisms of PANDAS/PANS when seemingly mimicking the signs and symptoms of autism & anxiety *could* be beneficial for at least some other parts of the wider autism spectrum...

Continue questioning and continue investigating seem to be the key lessons, as once again we are reminded that a diagnosis of autism should be a starting point and not 'the finishing line'.

  1. i think multiple thousands of children have infact had/still got and were given this problem via vaccine diseases into the bloodstream..vaccines in other words "causing" this ,,immune system dysfunction and brain encephalitis..which is why we see children regress after a vaccine,,most noticable with the MMR "simply" because of the childs age...
    And that is why early intervention sometimes works well..because if you treat early the PANS/PANDAS response is suppressed by building up the immune system and any inflammation brought down.( whether the parents realise or not that is what they are doing with , diet, high dose vitamins, disgaurding foods etc that cause the immune system to be impaired .
