The association notes that as families gather at this time of year, changes in a loved one may create concerns.

"It's critical for family members to follow up with someone if they noticed subtle changes in family members," Peter Reed of the Alzheimer's Association said in a statement. "Early detection of Alzheimer's disease gives people the opportunity to plan for their future and take advantage of the resources that are currently available to them such as the Alzheimer's Association 24/7 help line."

The help line -- 800-272-3900 -- is available to answer questions about Alzheimer's warning signs and provide guidance in finding help.

The association says those with Alzheimer's disease benefit when information is sought early and there is an early diagnosis. Not only may symptoms be improved with treatment -- and independence maintained longer -- but there is more time to plan for the future and most importantly, the patient can not only participate in decisions about care including living options, financial and legal matters but have the opportunity to develop relationships with those who will be partnering in this care.
