The Alzheimer's Disease Cooperative Study - Clinical Global Impression of Change (ADCS-CGIC) is a semi-structured interview designed to assess clinically relevant changes in patients with Alzheimer's disease.
Items in the ADCS-CGIC interview provide general information, and information about cognition, behaviour, social and daily functioning.
Responses to ADCS-CGIC interview result in a global clinical judgement of severity (at baseline) and clinically relevant change at subsequent visits.
Severity rated at baseline is only used for reference.
The severity at baseline is rated on a 7-point Likert-type scale from 1(normal, not ill at all) to 7 (among the most extremely ill patients).
The ADCS-CGIC relevant change is rated on a 7-point Likert-type scale from 1 (marked improvement) to 7 (marked worsening).
