Abstract
Objective To investigate whether there are changes in the ability of intertemporal choices in migraine sufferers. Method Thirty migraine sufferers and thirty healthy controls were investigated by Delay-discount Test. Results (1)The ratio of later-large (LL) choice in migraine suffers((18.15±17.53)%) was significantly lower than that in the healthy controls((35.37±20.70)%), and the difference was statistically significant(t=3.31, P<0.05). Under the immediate option for now selection conditions and no immediate option for not-now selection conditions, the ratio of later-large (LL) choice in migraine suffers((18.33±21.00)% , (17.96±18.09)%) was also significantly lower than that in the healthy controls((35.56±21.52)%, (35.19±22.05)%), and the difference was statistically significant(t=3.31, P<0.05; t=3.14, P<0.05). (2) Pearson correlation analysis showed that the Stroop Test of migraineurs was positively correlated with LL selection ratio under now conditions (r=0.49, P=0.006) and total LL selection (r=0.42, P=0.021) . Conclusion The ability of intertemporal choices in migraine sufferers has been impaired, which is correlated with executive function.
