Therefore, the relationship between dementia and gait velocity as a marker for mobility and falls in a cohort of frail elderly (mean age of 77.3 years) inpatients was assessed. Patients with dementia were expected to walk slower than patients without dementia. A trend was indeed observed: absolute gait velocity of 0.59 m/s in patients with dementia (n = 63) versus 0.65 m/s in patients without dementia (n = 62; p = 0.19). After adjustment for parkinsonism and walking aids, however, patients with dementia walked 0.44 m/s faster than patients without dementia (p = 0.02). Probable explanations are frontal lobe disinhibition and lack of insight, causing patients with dementia to walk relatively too fast in the context of their frailty. Therefore, the high risk of falls in dementia may be partially explained by the loss of control of gait velocity.
