Objective: To investigate the relationship between distribution of TCM syndromes and changes of cerebral image in patients with cognition disturbance after stroke and determine clinical assay values for congitive impairment so as to provide basis for interfering TCM risk factors of cognitive impairment after stroke and for treatment based on syndrome differentiation. Methods: Inpatients of apoplexy were assessed by neuropsychology and skull CT examination

and assessement of scores for TCM syndromes and analysis of correlativity were conducted. Results: The occurrence rate of the syndromes in patients of cognitive disturbance after stroke in the order of the probability was as following

i. e. deficiency of kidney-essence

retention of phlegm in orifices

stagnation of blood stasis in collaterals

hyperactivity of liver-Yang

retention of indigested food in the bowels

excessive pathogenic heat in the interior and deficiency of Qi and blood. Retention of turbid in bowels for cognitive impairment after basal ganglion infarction

excessive pathogenic heat in the interiror for cognitive impairment after infarction accompanied by encephalatrophy

deficiency of kidney-essence for cognitive impairment after left hemisphere or bilateral infarction had higher relative risk

but the effect of deficiency of Qi and blood on cognitive impairment after infarction in corona radiata showed negative correlation. Conclusion: There is significant correlativity of image alterations of apoplexy position and property of apoplexy with TCM syndromes

suggesting that kidney deficinecy

phlegm turbit

blood stasis and retention in bowels and pathogenic heat are possibly risk factors of cognitive impairment after stroke

but it is not closely related to deficiency of Qi and blood.
