Dementia is not a normal part of getting older, and early symptoms can be subtle. However, having one of these signs does not automatically mean someone has dementia—depression, medication effects, vitamin deficiencies, sleep problems, thyroid disorders, infections, and other conditions can cause similar changes.
10 early signs to pay attention to
-
Memory problems that interfere with daily life — repeatedly forgetting recently learned information, conversations, or appointments.
-
Difficulty planning or solving problems — trouble following a familiar recipe, managing bills, or completing previously routine tasks.
-
Difficulty doing familiar activities — getting confused while performing tasks that were once automatic or well practiced.
-
Confusion about time or place — losing track of dates, seasons, or where they are.
-
Problems with visual or spatial understanding — difficulty judging distances, recognizing objects, or navigating familiar places.
-
New problems with speaking or writing — struggling to find ordinary words, follow conversations, or express thoughts.
-
Frequently misplacing things — putting objects in unusual places and being unable to retrace steps to find them.
-
Poor judgment or decision-making — noticeably unusual financial, safety, or personal decisions.
-
Withdrawal from activities and social situations — losing interest in hobbies or interactions that were previously enjoyable.
-
Changes in personality or behavior — unusual irritability, anxiety, apathy, suspicion, or other persistent changes.
One important distinction
Normal aging: occasionally forgetting a name but remembering it later, or occasionally misplacing something.
More concerning: memory or thinking problems that are progressively worsening and interfere with everyday independence.
If these changes are new or progressing, it’s worth arranging a medical evaluation rather than trying to diagnose dementia from symptoms alone. Early assessment can identify treatable causes and, when dementia is present, provide opportunities for planning and treatment.
If someone develops sudden confusion, difficulty speaking, facial drooping, weakness/numbness on one side, or sudden vision/balance problems, don’t assume it’s dementia—seek emergency medical care, because these can be signs of a stroke.
