RECOGNITION, SCREENING AND STRUCTURED ASSESSMENT (NO DRUG THERAPY)
Autism spectrum disorder - disease-level clinical article (autism-spectrum-referral-full.txt)
Recognition is the whole of the primary-care job here, and the article is explicit that nothing confirms it: there is no laboratory test and no imaging study that can establish a diagnosis of ASD. Screening is universal rather than triggered by a worry - the American Academy of Pediatrics asks that every child be screened, on the reasoning that intervening early may change how a child turns out.
- THE THREE EARLY RED FLAGS - a child who does not respond to their own name by 12 months, does not point at things to show you they are interested by 14 months, and is not playing pretend by 18 months.
- THE GENERAL RED FLAGS - avoiding eye contact and preferring to be alone; difficulty understanding what other people feel, or naming their own feelings; delayed speech and language; repeating the same word or phrase over and over; answers that do not fit the question; distress at small changes; narrow, obsessive interests; repetitive movements; and unusual reactions to what they see, hear, feel or taste.

- WHAT THE ASSESSMENT MUST CONTAIN - a full history: past medical, developmental, social and family, with an eye on what can bear on development - prematurity, trauma, exposure to teratogens, and developmental problems elsewhere in the family. (Autism Spectrum Disorder - StatPearls - NCBI Bookshelf, NBK525976) A complete physical examination too: growth parameters, a detailed neurological examination, dysmorphic features, and any skin sign of a neurocutaneous disorder. (Autism Spectrum Disorder - StatPearls - NCBI Bookshelf, NBK525976) Hearing and vision are tested. (Autism Spectrum Disorder - StatPearls - NCBI Bookshelf, NBK525976) And a structured behavioural observation, which needs specific training to perform. (Autism Spectrum Disorder - StatPearls - NCBI Bookshelf, NBK525976)
- TEST THE HEARING BEFORE ACCEPTING THE LABEL. Hearing and vision tests are in the article's own assessment list, and a deaf child who does not turn to his name is not autistic.
- THE DIAGNOSIS IS MADE BY SOMEONE TRAINED TO MAKE IT - it takes a clinician trained in the criteria to put the history and the observation together. (Autism Spectrum Disorder - StatPearls - NCBI Bookshelf, NBK525976) The confirming tools are specialist instruments: the ADOS-2 cannot be given or scored without specific training. (Autism Spectrum Disorder - StatPearls - NCBI Bookshelf, NBK525976)
- TOOLS THAT CAN STRUCTURE A CLINIC INTERVIEW - a questionnaire such as the Social Communication Questionnaire or the Social Responsiveness Scale gives the interview a shape, and helps draw the history out. (Autism Spectrum Disorder - StatPearls - NCBI Bookshelf, NBK525976)
- WHAT TO EXCLUDE ON THE WAY - the article's environmental and metabolic differential is poisoning by a heavy metal, mercury and lead above all; the aminoacidurias; hypothyroidism; organophosphate exposure; and seizure disorders, atypical seizures in particular. Lead and organophosphate exposure are not rare in this setting.
- SEND FOR TESTS ONLY ON A REASON - the article images the brain where there is atypical regression, a head too small or too large, seizures, an abnormal neurological examination, or a cranial abnormality (Autism Spectrum Disorder - StatPearls - NCBI Bookshelf, NBK525976), and orders an EEG for seizures, for atypical regression, for loss of language, or for other neurological symptoms.
