%X Background: The aim of this study is to detect serum homocysteine increase (Hcy) and paraoxonase decrease together with methylenetetrahydrofolate reductase (MTHFR) and paraoxonase 1 (PON1) gene polymorphisms in Alzheimer's patients and to evaluate the correlation with clinic in these patients. Material and Methods: In our study; total 103 individuals were included and 51 of them had Alzheimer's disease (AD) diagnosis clinically according to DSM-IV criteria and 52 of them did not have AD. In patient and control group; Hcy levels and paraoxonase activity, MTHFR C677T ¨C A1298C and PON1 L55M - Q192R gene polymorphisms were investigated. Results: Average age of the patients in our study was found as 73.67¡À7.91 years. In patient group; Hcy level was significantly high (p:0,024) and paraoxonase activity was found low in patient group (p:0,047). In patients with MTHFR C677T and A1298C polymorphism, Hcy levels were high but there was no significant difference between groups (p>0,05). In PON1 L55M polymorphism PON levels were low (p<0,009). In patients with Q192R polymorphism PON levels were significantly high especially in heterozygote group (p:0,024). Conclusion: It was seen that Hcy levels were high and PON activity was low in Alzheimer's disease. MTHFR C677T and A1298C polymorphism could not be associated with AD but it was observed that the polymorphism could increase Hcy levels. As a result; PON 1 L55M polymorphism was thought to be a risk factor in AD and on the other hand Q192R polymorphism was thought to be a protective factor
