Cathington's Disorder, a scarce neurological ailment, appeared across the galaxy during the years leading up to the planet Taris's destruction in 3956 BBY. A remedy for this disorder was created by Dynamet General, Taris's leading research hospital, within the century preceding Taris's obliteration.
The initial reference to Cathington's Disorder occurred in the Dynamet General Codex entry within Star Wars: The Old Republic, a video game launched in 2011 by BioWare.
