Abstract:
Objective To explore the clinical characteristics of the cognitive disorder in patients with small vessel disease(SVD).Methods A total of 60 patients with SVD and 50 age,gender-matched healthy subjects were recruited consecutively from the Department of Neurology,Beijing Chaoyang Hospital. All the participants were performed by a battery of neuropsychological tests.The Fazekas scale was used to as-sess the severity of white matter lesions,and the scale of medial temporal lobe atrophy(MTA)was used to e-valuate the severity of medial temporal lobe.Results Patients with SVD were associated with global cogni-tive function deficits,including the general tests of MMSE((25.9±2.4)vs(28.1±1.7))and MoCA((23.0 ±3.7)vs(26.2±3.0)),and also with performances of AVLD-I((5.0±1.0)vs(8.2±2.0)),AVLT-D((3.7± 1.0)vs(9.3±1.9)),AVLT-R((7.6±1.5)vs(11.7±1.6)),TMT-B,Stroop B,Stroop C and DST(P<0.05). The score of MOCA was related negatively with Fazekas scale(r=-0.361,P=0.04).The severity of Fazekas had a positive relationship with the scores of MTA(r=0.449,P=0.032).Conclusion Patients with SVD are closely correlated to general cognitive impairment,especially with memory decline,attention and executive function,which may be attributed to the impairment of frontal-subcortical circle.
