Gerontophobia

Gerontophobia is the hatred or fear of older adults, or a fear of age-related self-degeneration (similar to gerascophobia). The term comes from the Greek γέρων – gerōn, "old man" and φόβος – phobos, "fear". Gerontophobia that stems from a fear of aging has been linked to thanatophobia, as fear of old age can be a precursor to fear of death. Gerontophobia can be caused by stereotypes of older adults displayed in the media.
