Recent drinking in alcohol use disorder as a modifiable risk factor of postural tremor and instability in mild cognitive impairment: An initial study

Age, irrespective of diagnosis, imbues liability onto postural stability, evidenced by longer sway paths and greater tremor velocity, especially under challenging conditions. Although the MCI group showed no evidence for disturbed balance metrics beyond those observed in controls, MCI participants comorbid for AUD exhibited deficits at similar levels to those shown by AUD participants in quiet standing, indicating recent drinking in individuals with a history of AUD as a modifiable risk factor for postural instability, a liability for falls and dementia.
