2. Challenges in Planning or Solving Problems
Some people experience changes in their ability to develop and follow a plan or to work with numbers. This may look like an inability to follow a familiar recipe, trouble keeping track of monthly bills, or difficulty concentrating on tasks that used to be straightforward. These tasks may also simply take much longer than they used to.
The normal-aging version of this is making an occasional error balancing a checkbook or needing a second look at a recipe used rarely. The Alzheimer's-related version is a broader, more persistent breakdown in the ability to follow multi-step processes at all.
3. Difficulty Completing Familiar Tasks
People with dementia often find it hard to complete everyday tasks so familiar that most of us never think about how we do them — not knowing the steps to prepare a familiar meal, operate a household appliance, or engage in a lifelong hobby.
Normal aging might mean occasionally needing help figuring out the settings on a brand-new microwave. The warning sign is struggling with an appliance or task that's been part of someone's routine for years.
4. Confusion with Time or Place
People with Alzheimer's disease can become lost on their own street, forget where they are and how they got there, and not know how to find their way back home. They may also lose track of dates, seasons, and the passage of time in a way that goes beyond simply forgetting what day it is.
Normal aging: getting confused about the day of the week but figuring it out shortly after. The warning sign: genuine disorientation in a familiar, well-known environment.
5. Trouble with Visual Images and Spatial Relationships
For some people, vision-related problems are an early sign of Alzheimer's. This can create difficulty with balance or reading, and problems judging distance or determining color and contrast, which can in turn cause issues with driving. It's worth noting that vision changes related to cataracts or other common age-related eye conditions are not, by themselves, a sign of Alzheimer's — this is one of the signs most easily confused with an unrelated and far more common medical issue.
6. New Problems with Words in Speaking or Writing
People living with Alzheimer's may have trouble following or joining a conversation. They might call something by the wrong name, repeat themselves during a conversation, or struggle noticeably to find the right word.
Everyone occasionally has a word on the tip of their tongue. The difference is frequency and severity — persistent word-finding struggles that meaningfully disrupt communication, rather than the occasional, momentary blank.
