Cognitive function and plasma somatostatin level in patients with leukoaraiosis / 临床神经病学杂志

ABSTRACT

Objective To explore the relationship between the cognitive function and plasma somatostatin(SS) level in the patients with leukoaraiosis(LA).Methods According to the clinical findings and CT imaging,the subjects were divided into three groups26 patients with LA and dementia, 47 patients with LA but without dementia, and the normal controls for 38 cases. The three groups were determined by means of Hasegawa's Dementia Scale(HDS)and SS levels in plasma.Results As compared with the control group,HDS score and plasma SS level in patients with LA (including dementia group and non dementia group) decreased remarkable(P0.05).Conclusion LA might be the cause of cognitive impairment,the concentrations of plasma SS had declined before dementia did not occur,the cognitive impairment in patients with LA might relate to the decrease of SS levels in the body.
