Autism and obstacles to medical diagnosis and treatment

The title of this post reflects the title of the paper by Marcia Datlow Smith and colleagues* which was given to me by Natasa (many thanks) a few days back. The paper is from 2012 so I don't think we can consider this a post about new research. Nevertheless the subject matter of the paper is potentially very important: "describing individuals with autism whose catastrophic illnesses were misdiagnosed due, at least partially, to their autism".

@ Wikipedia
It is indeed a pity that the Smith paper is not open-access (at the time of writing anyway) because it contains two very powerful accounts of how symptoms and medical diagnoses were "overlooked and misread" partially as a result of the presentation of autism. I don't say this to somehow 'blame autism' or anything like that; merely that extra vigilance and a greater degree of acceptance that people with autism are just as prone as everyone else to potential issues affecting health and wellbeing, should be an intrinsic part of the message when it comes to ensuring appropriate healthcare coverage. Think person first, autism diagnosis second; a theme which was also part of the recent NICE Quality Standard and another very important document which is well worth a read.

The authors document the lives of two people diagnosed with autism, Dana, a 54-year old man and Shannon, a 27-year old woman. I'm not often moved by the contents of a peer-reviewed 'science' paper with it's focus on cold, hard objectivity, but reading the account of how Dana was subsequently diagnosed with amyotrophic lateral sclerosis (ALS) (also known as Lou Gehrig's disease or motor neurone disease) and his eventual death 3 weeks after receiving his diagnosis was powerful. Likewise the description of how Shannon eventually came to receive a diagnosis of multiple sclerosis (MS) and the difficult path she had to navigate to arrive at that diagnosis makes for some pretty uncomfortable reading.

I'm not going to post all the details of these case reports because (a) that might be tantamount to plagiarism and (b) I don't want this post to turn into some sort of medical spectacle. Suffice to say that for each person, issues such as the "lack of expressive speech" and a "history of occasional bouts of oppositional behavior" did little to aid the art of medicine in arriving a suitable diagnosis for their symptoms. That however the descriptions include certain professionals suggesting that such symptoms were as a result of "major depressive disorder" with accompanying recommendations for "medication adjustment" is however, a slightly worrying trend and brings to mind that issue of the use of antipsychotics in dementia care (see here). Even further that electroconvulsive therapy (ECT) was one of the treatment choices implemented prior to Shannon being diagnosed with MS (and indeed correlated with "two grand mal seizures") is a further worry.

The common theme of these accounts is, in the authors words, one of caution in how: "stories of Dana and Shannon serve to motivate health practitioners to take care before attributing functional decline or other physical symptoms to a patient's mental illness". I think the authors were being quite general in their description of 'mental illness' over and above trying to specifically describe autism with those words. Their implication however on how dogma about autism somehow just being seen as a stand-alone conditions occurring in a diagnostic vacuum alongside how concepts like 'challenging behaviours' have built up over the years, might not necessarily serve people with autism best is an important part of the stories of Dana and Shannon.

I don't want to drag out further discussion about the Smith paper in this post. I would like to think that some readers might themselves try and locate the full-text paper and read about how good modern-day healthcare really should be able to overcome barriers such as a person's lack of language when it comes to a label for their symptoms and onwards any appropriate care if available and required. Think visual issues and autism as one example. Understanding that people with autism may have medical comorbidity and needs which may surpass the presentation of the core behavioural symptoms as per other examples, is also an important part of how we view the spectrum and indeed, how improvements in quality of life may be made by patching up any health inequality.
