Etymologically, the entry records: Originally named after Julius Hallervorden and Hugo Spatz but renamed to pantothenate kinase-associated neurodegeneration after Hallervorden and Spatz's Nazi party ties were discovered and the eponymous distinction was revoked. Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is Hallervorden-Spatz disease, spelled H-A-L-L-E-R-V-O-R-D-E-N---S-P-A-T-Z- -D-I-S-E-A-S-E, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
