Recognizing early signs of dementia allows for timely medical evaluation, lifestyle interventions, and care planning. Occasional forgetfulness—such as misplacing keys or forgetting a name temporarily—is a normal part of aging. However, persistent changes that interfere with daily life warrant professional medical evaluation.
-
Disruptive Short-Term Memory LossForgetting recently learned information, asking the same question repeatedly, or relying heavily on memory aids for tasks previously handled independently. Unlike typical age-related changes, the forgotten information rarely comes back to mind later.
-
Difficulty Planning or Solving ProblemsStruggling to follow a familiar recipe, balance a checkbook, or keep track of monthly bills. Everyday tasks requiring sequential steps or working memory become unusually challenging and take much longer to complete.
-
Trouble Completing Familiar TasksFinding it hard to drive to a location visited for years, operate basic household appliances, or remember the rules of a favorite game.
-
Confusion with Time or PlaceLosing track of dates, seasons, or the passage of time. Someone with early dementia may forget where they are or how they arrived there, or struggle to understand events that are not happening immediately.
-
Trouble Understanding Visual Images and Spatial RelationshipsExperiencing vision changes unrelated to cataracts, such as difficulty judging distance, determining contrast, or identifying colors. This can lead to balance issues or difficulty reading and driving safely.
-
New Problems with Words in Speaking or WritingStruggling to join or follow a conversation, stopping mid-sentence with no idea how to continue, or repeating themselves. They may struggle to find the right word or call things by the wrong name (e.g., calling a watch a “hand-clock”).
-
Misplacing Things and Losing the Ability to Retrace StepsPutting items in unusual places (such as keys in the refrigerator) and being unable to go back over their steps to find them. As the condition progresses, they may accuse others of stealing.
-
Decreased or Poor JudgmentDemonstrating poor decision-making with finances (such as giving large sums to telemarketers), neglecting personal hygiene, or wearing inappropriate clothing for the weather (e.g., a heavy coat on a hot summer day).
-
Withdrawal from Work or Social ActivitiesPulling away from hobbies, social engagements, sports, or work projects. This often happens because holding conversations or tracking complex social dynamics feels overwhelming or embarrassing.
-
Changes in Mood and PersonalityBecoming easily confused, suspicious, depressed, fearful, or anxious. A person may become upset quickly in familiar settings or when pushed outside their comfort zone.

| Making a occasional mistake when balancing a checkbook | Inability to manage daily finances or follow a familiar plan |
