How to tell if a patient has Alzheimer’s or Lewy body disease

Gait impairment shows distinct patterns in Alzheimer’s disease and Lewy body disease patients, a UK study suggests.
Evidence is mounting that particular types of gait impairment are associated with impairment in distinct cognitive domains, say the authors from Newcastle University Institute of Ageing in Newcastle Upon Tyne, UK.
However, most studies have only measured gait speed.
In this study, researchers enrolled 45 individuals with mild cognitive impairment or dementia due to Lewy body disease, 36 with Alzheimer’s disease, and 29 functionally independent controls without cognitive impairment or dementia diagnoses.
