Measure Description |
Time Frame |
---|---|---|
CDR score of cognition deteriorating group and stable group
Time Frame: through study completion, an average of 1.5 year
|
The CDR is a 5-point scale (0、0.5、1、2、3) used to characterize six domains of cognitive and functional performance applicable to Alzheimer disease and related dementias: Memory, Orientation, Judgment & Problem Solving, Community Affairs, Home & Hobbies, and Personal Care. The necessary information to make each rating is obtained through a semi-structured interview of the patient and a reliable informant or collateral source (e.g., family member). Global score 0 = Normal、0.5 = Very Mild Dementia、1 = Mild Dementia、2 = Moderate Dementia、3 = Severe Dementia. The cognition deteriorating group is defined as CDR score declines from 0 or 0.5 at Month 3 to >=1 at Month 18. The cognition stable group is defined as CDR score remains at 0 or 0.5 at Month 18. |
through study completion, an average of 1.5 year
|
Imaging positive and negative conditions
Time Frame: through study completion, an average of 1.5 year
|
PET images are visually assessed by independent raters, who are nuclear medicine doctors and blinded to all clinical and diagnostic information.
The raters classify each scan as 0-1 (no significant uptake)、2 (suspicious uptake)、3-4 (significant uptake).
The score >= 2 is deemed as positive condition.
