10 Early Signs of Dementia You Shouldn’t Ignore
Dementia isn’t a normal or inevitable part of aging. It describes problems with memory, thinking, language, or behavior that become significant enough to interfere with everyday life. One symptom alone doesn’t mean someone has dementia—many treatable conditions can cause similar changes.
-
Memory problems that affect daily life
Frequently forgetting recently learned information, important appointments, or conversations—and repeatedly asking the same questions. -
Difficulty performing familiar tasks
Struggling with activities that were previously routine, such as following a familiar recipe, managing household appliances, or handling finances. -
Problems finding words or following conversations
Losing track of a conversation, using unusual words for familiar objects, or having increasing difficulty expressing thoughts. -
Getting lost in familiar places
Becoming confused about where they are, how they got somewhere, or how to return home. -
Difficulty with planning or problem-solving
Trouble following a familiar sequence of steps, managing a budget, paying bills, or making ordinary decisions. -
Misplacing things in unusual ways
Putting objects in inappropriate places and being unable to retrace their steps to find them. -
Changes in judgment
Making decisions that are markedly out of character—for example, becoming unusually vulnerable to scams or neglecting important responsibilities. -
Changes in mood, personality, or behavior
New or persistent withdrawal, anxiety, irritability, suspiciousness, apathy, or personality changes can sometimes accompany cognitive decline. -
Difficulty understanding visual or spatial information
Problems judging distance, navigating spaces, recognizing objects, or coordinating movements can occur with some forms of dementia. -
Losing interest in previously familiar activities
Someone may increasingly withdraw from hobbies, social activities, work, or other activities because they are having difficulty following or participating in them.
When should you seek medical advice?
The key warning sign is progressive change that interferes with everyday functioning. If you or someone close to you is experiencing several of these changes, arrange an evaluation with a doctor. They can check memory and thinking and look for potentially reversible causes such as medication effects, depression, sleep problems, vitamin deficiencies, thyroid disorders, or infections.
Sudden confusion is different. If confusion develops abruptly over hours or days—especially with weakness, difficulty speaking, severe headache, fever, or other neurological symptoms—seek urgent medical attention rather than assuming it is dementia.
