Today’s typo might look like a classic case of dyslexia, but letter or word reversal is just one symptom of this learning disability that the Mayo Clinic defines as “an impairment in your brain's ability to translate written images received from your eyes into meaningful language.” Other symptoms include late talking, difficulty rhyming or spelling, delayed reading ability, problems understanding what is heard, trouble remembering the sequence of things, inability to sound out unfamiliar words, and difficulty with foreign language acquisition.
Dyslexia is the most common learning disability in children, and it usually occurs in those with average or above-average intelligence. Although a dyslexic may have trouble understanding spoken or written language, his or her own speech is most often unaffected.
Dsylex* is a low-probability typo. There are currently 2 occurrences of it in the OhioLINK database, and keyword search of WorldCat yields only 8 results. Most are for versions of the film Just Another Stupid Kid–which is how others might mistakenly judge someone with dyslexia. The variants Dylex* and Dylsex* each bring up a single hit.
