Since Alzheimer’s attacks the brain, the major visible changes to a person descending into Alzheimer’s are changes in behavior. So it is certainly no surprise that in general, the people who can most knowledgeably speak to a person’s behavioral changes are that person’s family and friends. Because of this, the “AD8, A brief informant interview to detect dementia” was developed at Washington University for use in interviewing family and friends. It contains eight yes-no questions dealing with issues such as:
Less interest in hobbies/activities
Trouble handling complicated financial affairs (e.g., balancing checkbook, income taxes, paying bills)
Trouble remembering appointments
A pdf of the complete AD8 is available here; Permission to use the AD8 can be obtained here.
(It would seem that a combination of the AD8 with the UPSIT “scratch and sniff” test would make a moderately good inexpensive screening combination.)
