Risk score of memory disturbance and dementia in acute ischemic stroke patients
Keywords:
Acute ischemic stroke, risk score, memory disturbance, dementiaAbstract
This study was a cohort study design. That aims to provide the total risk score for predicting memory disturbance and dementia in 401 acute ischemic stroke patients treated at Srinakarin Hospital, Khon Kaen Hospital, and Chum-phae Hospital between January 1 - December 31, 2017. Data were collected by questionnaire and review of medical records three times include before discharge from the hospital, three months, and six months after a diagnosis of acute ischemic stroke. Factors associated with memory disturbance and dementia have been analyzed by logistic regression statistic, and the risk score was defined from β Coefficients of each factor. The sensitivity, specificity, and Receiver operating characteristic (ROC) of the risk score have been calculated. The results of this study demonstrated the factor as gender, age, education level, and severity of stroke can be used to calculate the risk score for predicting the memory disturbance and dementia in acute ischemic stroke patients during three times were 5 points. ROC curve was 0.81, 0.83, and 0.85, respectively. Sensitivity was 76.2%, 80.9%, and 84.1%, respectively. Specificity was 71.8%, 68.7% and 68.6%, respectively. Hence, the risk score obtained from this study can be used to screen patients with acute ischemic stroke for the risk of memory disturbance and dementia.
