Morphology

senile + dementia

The meaning 'a form of dementia occurring in elderly people' is directly and compositionally derived from 'senile' (relating to age-related mental decline) + 'dementia' (a disorder causing memory loss and personality changes). This adjective+noun combination follows a regular, cross-linguistic pattern, so a B1 learner who knows both constituents should be able to infer the MWE's meaning.

Etymology

Senile dementia puts together senile (a word meaning 'old') and dementia (a word for losing memory and clear thinking). Imagine someone's memories and thinking slowly fading as they get older — that's why it means serious 'memory loss' in elderly people.
