Objective Although a few reports suggested that cognitive function impairment could be found in adult patients with moyamoya disease(MMD),there were still many aspects that are unclear.The aim of our study was to assess the cognitive function of adult patients with MMD and its clinical subtypes.Methods 49 patients with MMD and 23 healthy controls were asked to take cognitive function tests.Cognitive function tests included IQ,prospective memory(PM),immediate memory(IM),verbal fluency(VF),visual breadth,attention,retrospective memory(RM),Stroop test,Wisconsin Card Sorting Test,Trail-Making Test Part A(TMT-A)and Continuous Performance Test(CPT).Independent t-analysis,one-way analysis of variance and Pearson correlation were used to seek for differences between subgroups and the correlation between cognitive variables.results Compared with healthy controls,adult patients with MMD had a comprehensive cognitive impairment,including IQ,PM,VF,attention,RM,Stroop,CPT and TMT-A,with more serious impairment in PM and attention.PM and RM were separated,indicating that they were independent of each other.Pattern of attention was significantly different from healthy controls.Female patients were better than male patients,where significant differences in PM,IM,Stroop and WCST could be found.The haemorrhagic patients exhibited poorer in the dimension of PM and RM than the ischaemic.The headache subtype exhibited poorer than healthy controls.PM,RM,attention and executive function were moderately correlated with each other.Conclusions Adult patients with MMD had a wide range of cognitive impairment with more serious impairment in memory and attention.Differences in cognitive function existed between the different subtypes of adult MMD.
