BOSTON - Memory problems that are often dismissed as a normal part of aging may not be so harmless after all.

Noticing you have had a decline beyond the occasional misplaced car keys or forgotten name could be the very earliest sign of Alzheimer's, several research teams are reporting.

Doctors often regard people who complain that their memory is slipping as "the worried well," but the new studies show they may well have reason to worry, said Maria Carrillo, a senior scientist at the Alzheimer's Association.

One study found that self-reported memory changes preceded broader mental decline by about six years. Another tied these changes to evidence on brain scans that dementia is setting in.

"Maybe these people know something about themselves" that their doctors don't, "and maybe we should pay attention to them," said Dorene Rentz, a Massachusetts General Hospital psychologist. She helped run one of the studies, which were discussed Wednesday at the Alzheimer's Association International Conference in Boston.

About 35 million people worldwide have dementia, and Alzheimer's disease is the most common type. It causes a slow decline in thinking and reasoning ability. Memory trouble that disrupts daily life is one symptom.

Don't panic, though: The researchers are not talking about "senior moments," those small, temporary lapses most everyone has, said Creighton Phelps, a neuroscientist with the U.S. National Institute on Aging. They are talking about real memory loss, in which the information doesn't come back to you later, not even when people remind you of what you forgot, he explained.

A true decline is a change in your normal pattern. "You're starting to forget things now that you normally didn't - doctor appointments, luncheon engagements, the kids are coming over ... things that a year or two ago you wouldn't," said Dr. Ronald Petersen, director of the Mayo Clinic's Alzheimer's Disease Research Center.

Pati Hoffman, of Carol Stream, Ill., used to design menus and organize events for restaurants but began forgetting where she filed things in her computer.

"I really just kind of started struggling. Something wasn't right. I would have to bring my work home, spread it all over the floor, sort it and then try to get it done so that nobody at work would know I was having this difficulty," she said. Driving to familiar places, "I would think, 'I know where I am, but I don't know how to get out of here.'"

Two neurologists said it was just stress and anxiety, and one prescribed an antidepressant. A third finally diagnosed her with early-onset Alzheimer's disease four years ago. She was 56.

Warning signs

The Alzheimer's Association lists 10 warning signs of the disease:

• Memory changes that disrupt daily life.

• Challenges in planning or solving problems.

• Difficulty completing familiar tasks at home, at work or at leisure.

• Confusion with time or place.

• Trouble understanding visual images and spatial relationships.

• New problems with words in speaking or writing.

• Misplacing things and losing the ability to retrace steps.

• Decreased or poor judgment.

• Withdrawal from work or social activities.

• Changes in mood and personality.
