Increased oxidative stress and free radicals can cause neuron cell damage. Serum 8-hydroxy-2-deoxyguanosine (8-OHdG) concentration is the result of free radical interactions with cluster C8 guanine bases, which is used to assess the degree of neuron cells damage and the oxidative stress levels. Increased serum 8-OHdG concentration indicating brain cells damage is reflected in neurological deficits based on the The National Institutes of Health Stroke Scale (NIHSS). The aim of this study was to determine the correlation between serum 8-OHdG concentration and the degree of neurological deficit by NIHSS. This was an observational cross-sectional study. Seventy-two patients with acute ischemic stroke who visited Dr. Hasan Sadikin General Hospital Bandung during the period of August 2013 to January 2014 were enrolled. Statistical analysis was performed using Kruskal-Wallis test and rank Spearman’s correlation test. The mild neurological deficit median serum 8-OHdG concentrations was 3.9 ng/mL (3.3–12.0 ng/mL), moderate was 23 ng/mL (8.0–51.0 ng/mL), and severe was 77.5 ng/mL (54.0–97.0 ng/mL). Correlation of serum 8-OHdG concentration with neurological deficits in acute ischemic stroke rs=0.912 (p<0.001). In conclusion, serum 8-OHdG have a strong meaningful positive correlation with neurological deficits. Serum 8-OHdG concentration may be considered to be use in the assessment of discrepancy between CT scan and clinical symptoms and in health facilities with no CT scan facility.
