As far as the incremental value of copeptin compared with ABCD2 score is concerned, De Marchis et al. [41], having studied 302 TIA patients, demonstrated that plasma baseline copeptin levels were strongly correlated with recurrent stroke within 3 months after TIA, while similar association between copeptin concentration and TIA recurrence during follow-up was not observed. The gene discussed is AVP; the disease is transient ischemic attack.
