Abstract Objective The association between the APOE ε 4 allele and depression was investigated in a retrospective study of 323 AD patients. Methods Patients were divided into demographically comparable groups based on the presence or absence of depression. Results Results showed that the frequency of APOE ε 4 allele was significantly higher in the depressed vs non‐depressed AD patients (72% and 58%, respectively), and an interaction revealed that women possessing the APOE ε 4 allele were almost four times more likely to be depressed than those without the ε 4 allele. Conclusion Results are consistent with recent suggestions that the APOE ε 4 genotype may be over‐represented among depressed women with AD and highlight the need for additional research investigating the links between APOE genotype, mood, and gender.
