Homosistein Plasma dan Perubahan Skor Fungsi Kognitif pada Pasien Pasca Stroke Iskemik

Abstract

Plasma homocysteine and cognitive function score change in post ischemic stroke patients Background: Increase of total homocysteine level is a strong risk factor for cerebrovascular disorder and is correlated with decrease of performance in sort of cognitive tests, including mini mental state examination (MMSE) and clock drawing test (CDT). The aim of this study was to prove the correlation between plasma homocysteine level and change in cognitive function score in postischemic stroke patients. Methods: The design was cross-sectional. The subjects were post-ischemic stroke patients, treated at B1-ward Dr. Kariadi Hospital Semarang from January-June 2010. Plasma homocysteine levels were measured on the first week post onset of ischemic stroke using venous blood at GAKI Laboratory Dr. Kariadi Hospital and cognitive function score was examined using MMSE and CDT on the first and 12th week post onset. Datas were analyzed using descriptive analysis and Spearman\u27s rho correlation test. Results: Of 30 patients, there were 13 patients with homocysteinemia (43.3%) and 17 with hyperhomocysteinemia (56.7%). There was significant difference of MMSE and CDT score decrease in the first and 12th post onset, with p=0.000 and p=0.001 respectively. Spearman\u27s rho showed correlation between plasma homocysteine level and cognitive function score based on MMSE with r=-0.837; p=0.000, and based on CDT with r=-0.655; p=0.000. Conclusions: There is strong negative correlation between plasma homocysteine level and change in cognitive function score on the first week post onset of ischemic stroke
