Cerebrospinal fluid MR dynamics and risk of falls in the elderly.

Rationale And Objectives: To investigate the relationship between CSF dynamics and risk of falls of unknown origin in the elderly.

Population And Methods: Phase contrast MR studies allowed CSF aqueductal flow quantification on 23 community-dwelling older people initially explored for mild cognitive impairment. Mobility assessment included report of falls, talking walking test, stance test, one leg standing test, up and go test, and measurement of fast gait speed.
