From this abstract, it sounds as if it is the co-morbid disorders which so commonly occur with Tourette's and are the cause of sudden rage attacks and intermittent explosive episodes reflex a high level of psychosocial morbidity.
Even though the children studied here had only mild tic activity, they exhibited a high level of neurological disturbance. To me, that means that possibly this young woman's hiccups were caused by a mild form of Tourette's and along with Tourette's she suffered other neuro-differences. Sadly, it appears that rage or an explosive episode was an outcome.
