Evaluation of a functional assessment tool in patients with mild cognitive impairment or Alzheimer’s disease in Lima, Peru

Functional assessment screening tools are crucial for dementia evaluations. The Alzheimer’s Disease Cooperative Study‐Activities of Daily Living (ADCS‐ADL) scale is a versatile functional assessment screening tool that can be used to monitor functional decline of patients with Alzheimer’s disease (AD). We sought to evaluate the validity and reliability of the ADCS‐ADL scale in Peruvian patients with mild cognitive impairment (MCI) or AD.
