Therefore, in this pilot study, we aimed to examine the feasibility and acceptability of the informant AD8 for case finding of cognitive impairment in a primary healthcare setting in Singapore.
Eligible patients are those who (1) were aged 60 and above, (2) provided consent, (3) and had an informant with sufficient language skills in English, Chinese, or Malay to complete the AD8. Reasons for declining participation were collected.
Overall, the AD8 has proved more useful than the Mini Mental State Examination in picking out patients with the very earliest signs of cognitive impairment, Dr.
Because it provides a picture of change related to baseline, the AD8 avoids the problem of a "snapshot" test, which could, for example, falsely identify cognitive problems in someone who has never had a good memory.
The AD8 asks informants to answer yes, no, or don't know to whether the patient has changed in eight areas: problems with dally judgment and decision making; decreased interest in hobbies or activities; repeating things over and over; trouble learning how to use a new tool or appliance; forgetting the month or year; trouble with financial affairs; trouble recalling appointments; and daily problems with thinking and memory.
The AD8 sounds good on the surface, but how it will fit into a busy primary care day is still unclear, said Dr.
Although family complaints have been viewed as valid in at least 1 commonly used screening instrument, the AD8 (with more than 2 of 8 complaints likely to aid in dementia detection) (18) does not reflect severity of impairment, nor does it provide a score to follow a patient's course over time.
Numbers are easily recorded and compared, while impressions or even a positive (>2) AD8 score are less precise.
"The AD8 gives us a brief and very low-cost alternative that takes a few minutes of the informant's time to screen for dementia and thus identify those individuals who need follow-up evaluations to determine if there truly are signs of Alzheimer's," said John C.
"Based on our results, the AD8 appears to be superior to conventional testing in its ability to detect signs of early dementia.
One recent study found that the AD8
, an 8-question, 2-minute screening test given to a close friend or family member, was superior to conventional testing in its ability to detect signs of early dementia.
