Copper is a metal element which plays a pivotal role in the pathology of various neurological disorders including cognitive disorders. Previous studies have shown different relationships between serum levels of copper and cognitive impairment. This study aimed to investigate the relationship between serum levels of copper and cognitive disorders in the elderly in Amirkola.

FINDINGS: In this study, of 1616 elderly people, 1004 people in the age group 60-90 years were examined. 518 men and 486 women were existed with a significant difference in serum level of copper between the sexes (p The results showed that cognitive impairment is associated with serum levels of copper
