It would be interesting to revisit some of these larger population study datasets—for example, the extensive dataset associated with the Danish study (Meng et al., 2012)—to determine whether biological sex, APOE ε4 genotype (if described in the patient files) and specific antidepressant drug usage (including for off‐label indications (Wong et al., 2016)) interact to impart greater odds of developing a dementia‐related phenotype. Here, APOE is linked to dementia.
