For example, someone might repeatedly ask what time a family gathering is, even after receiving the answer several times.
By contrast, occasionally forgetting a name but remembering it later is generally considered a normal part of aging.
2. Difficulty Planning or Solving Problems
Some people begin having trouble with tasks that once felt routine.
They may find it difficult to:
-
Follow familiar recipes
-
Balance a household budget
-
Manage monthly bills
-
Keep track of appointments
-
Follow multiple-step instructions
-
Organize daily responsibilities
These changes may reflect difficulties with attention, reasoning, or executive function.
Everyone makes occasional mistakes, but persistent difficulty with familiar tasks deserves evaluation.
3. Confusion About Time or Place
Another possible early sign involves becoming disoriented.
A person may:
-
Forget the date or season
-
Lose track of time
-
Become confused about where they are
-
Have difficulty following directions in familiar places
-
Miss scheduled events because they lose track of time
Some individuals may become lost while driving routes they have used for years.
Because disorientation can increase the risk of injury, it should never be ignored.
4. Changes in Judgment, Personality, or Social Behavior
Alzheimer's disease can affect more than memory.
Some individuals experience noticeable changes in:
-
Decision-making
-
Social interactions
-
Mood
-
Motivation
-
Personal hygiene
-
Financial judgment
