APOE ϵ4, rated life experiences, and affect among centenarians.

Objectives: The purpose of this study was to assess the relationship between apolipoprotein E (APOE), life events and engagement, and subjective well-being (as measured by positive and negative affect) among centenarians. Based on the life stress paradigm, we predicted that higher levels of stress would allow APOE to influence positive and negative affect.

Method: 196 centenarians and near-centenarians (98 years and older) of the Georgia Centenarian Study participated in this research.
