This is a medical case study however, not a journalistic piece and you two are being at least a little bit unfair, I think. Since seizures and sudoku are not a common combination, upon seeing the title, I assumed it was something conditional. This sort of Crucifix Glitch—ahem, environmental epilepsy—is also very uncommon and usually genetic, which makes this all the more interesting.
Here, it seems inhibitory circuits in a section of the right parietal lobe were damaged; without dampening, as with any feedback system, the system quickly goes out of whack. What's interesting here is that in this patient, the only activity that seems to generate a pattern resulting in such over-excitation is playing sudoku. But surely that's not the only Visuospatial task he partakes in, so why? All we're left with is: "Our patient stopped solving sudoku puzzles and has been seizure free for more than 5 years".
