10 Early Signs of Dementia
Dementia isn’t a normal part of aging. Early symptoms can be subtle, and occasionally forgetting something doesn’t necessarily mean dementia. What matters is persistent or progressive change that begins interfering with everyday life.
-
Memory loss that affects daily life — repeatedly forgetting recent conversations, appointments, or information.
-
Difficulty doing familiar tasks — struggling with cooking, managing finances, using familiar appliances, or following a usual routine.
-
Problems with planning or problem-solving — difficulty following a recipe, paying bills, or handling tasks that previously seemed routine.
-
Getting confused about time or place — losing track of dates, seasons, or where they are.
-
Difficulty finding words — frequently losing the right word or having trouble following or joining conversations.
-
Misplacing things unusually often — putting objects in inappropriate places and being unable to retrace steps.
-
Poor judgment — noticeably unusual decisions involving money, safety, hygiene, or other everyday matters.
-
Withdrawal from activities — losing interest in hobbies, social activities, or work that the person previously enjoyed.
-
Changes in mood or personality — unusual anxiety, suspicion, irritability, apathy, or other persistent changes.
-
Difficulty recognizing visual or spatial information — problems judging distance, navigating familiar places, reading, or recognizing objects.
🧠 Simple habits that support brain health
There isn’t a single habit that guarantees prevention of dementia, but several behaviors are associated with better brain and cardiovascular health:
-
Exercise regularly: Aim for about 150 minutes of moderate physical activity per week, if medically appropriate.
-
Keep blood pressure, cholesterol, and blood sugar under control.
-
Don’t smoke, and avoid excessive alcohol.
-
Eat a balanced diet emphasizing vegetables, fruit, whole grains, legumes, nuts, fish, and other minimally processed foods.
-
Stay socially connected and keep your brain engaged through learning, reading, games, music, or meaningful activities.
-
Get adequate, regular sleep.
-
Protect your hearing and use hearing aids when recommended.
-
Prevent head injuries, including by using seat belts and appropriate protective equipment.
When to talk to a doctor
If you or someone close to you has progressive memory or thinking changes that interfere with everyday activities, arrange a medical evaluation. Many conditions—including medication effects, depression, sleep problems, thyroid disorders, and vitamin deficiencies—can cause cognitive symptoms and may be treatable.
A sudden change in memory, confusion, speech, strength, or behavior is different and can indicate an emergency such as a stroke or infection; it warrants prompt medical attention.
