This is particularly important for at-risk populations such as Apolipoprotein E (APOE) ε4 allele carriers (Harris, 2024), those with a family history of dementia (Lee et al., 2022), and those at an early stage of cognitive decline, known as Subjective Cognitive Decline (SCD) (Jessen et al., 2014). Here, APOE is linked to dementia.
