10 Signs of Dementia You Shouldn’t Ignore
Occasional forgetfulness is normal with aging. Persistent changes that interfere with everyday life are different and deserve medical evaluation. Dementia is not one specific disease; it describes problems with memory, thinking, reasoning, and daily functioning caused by various conditions.

Watch for these warning signs:
Memory loss that disrupts daily life — repeatedly forgetting recent information or asking the same questions.
Difficulty planning or solving problems — trouble managing bills, medications, recipes, or familiar tasks.
Difficulty completing familiar activities — getting confused while doing something previously routine.
Confusion about time or place — losing track of dates, seasons, or where they are.
Problems with vision or spatial awareness — difficulty judging distances, reading, or recognizing objects.
New problems with speaking or writing — struggling to follow or join a conversation or repeatedly losing words.
Misplacing things and being unable to retrace steps — particularly when objects are put in unusual places.
Poorer judgment — unusual financial decisions, unsafe behavior, or inappropriate choices.
Withdrawal from work or social activities — losing interest in hobbies and activities previously enjoyed.
Significant changes in mood or personality — increased suspicion, anxiety, fear, confusion, irritability, or unusual behavior.

Habits worth starting today
These habits cannot guarantee prevention of dementia, but they support overall brain and cardiovascular health and may reduce dementia risk:
Exercise regularly — aim toward about 150 minutes of moderate activity per week if medically appropriate.
Control blood pressure, cholesterol, diabetes, and other cardiovascular risk factors.
Don’t smoke.
Eat a nutritious diet, emphasizing vegetables, fruits, whole grains, legumes, fish, and other minimally processed foods.
Sleep well and maintain a regular sleep schedule.
Stay socially connected with family, friends, community groups, or volunteering.
Keep your brain active by learning skills, reading, doing meaningful activities, or pursuing hobbies.
Protect your hearing and use hearing aids when recommended.
Limit alcohol rather than using it as a health strategy.

Don’t assume it’s “just old age”
If these changes are new, progressive, or interfering with everyday activities, arrange a medical evaluation. Memory problems can also result from potentially treatable issues such as medication effects, depression, sleep problems, vitamin deficiencies, thyroid disorders, or other medical conditions.

One important distinction: suddenly becoming confused over hours or days is not typical dementia and can indicate delirium or another urgent medical problem requiring prompt assessment.
