Introduction
- hypothesis that a symptom & disorder do not cause one another, but result from a common cause
- for example, hearing loss & dementia both result from a common neurodegenerative process in the aging brain
- hearing loss may result from degeneration of the stria vascularis, loss of hair cells & loss of afferent neurons in the central auditory pathways, but these are not the same neurodegenerative process underlying dementia[1]
