How to Notice Early Signs of Dementia and Know What to Do

Start by asking whether the change is occasional or whether it disrupts daily life. The CDC explains that some memory changes can happen with age, but dementia is not a normal part of aging and affects remembering, thinking clearly, or making daily decisions.

Notice patterns such as asking the same question again and again, forgetting recent conversations, missing appointments, or misplacing items in unusual places. Mayo Clinic lists repeated questions, trouble with familiar tasks, getting lost, and mood or behavior changes as early warning signs that should be evaluated.

Pay attention if a person starts struggling with tasks they used to manage, such as following a familiar recipe, shopping, handling change, paying bills, or organizing steps in order. The NHS notes that difficulty concentrating and carrying out familiar daily tasks can be common early dementia symptoms.

Look for new difficulty following a conversation, finding the right word, naming familiar objects, or expressing thoughts clearly. The National Institute on Aging includes trouble speaking, understanding, reading, writing, and using unusual words for familiar objects among possible dementia symptoms.

Take note if someone gets lost in a familiar neighborhood, cannot explain how they arrived somewhere, or seems repeatedly confused about dates, seasons, or location. The CDC lists getting lost in a familiar neighborhood as a sign that may point to dementia.

Early dementia can sometimes show up as becoming more withdrawn, anxious, suspicious, irritable, or less interested in usual activities. The NHS includes mood changes and becoming more withdrawn or anxious among possible dementia symptoms, but these changes can also have other causes.

Keep a simple dated list of what happened, how often it happened, and whether it affected daily life or safety. The NHS recommends bringing someone who knows the person well to an appointment because they can describe changes and help remember what was discussed.

See a doctor if memory, thinking, behavior, or daily tasks are changing, especially if the changes are repeated or getting worse. Memory problems do not always mean dementia; medical evaluation can check for other causes such as depression, anxiety, delirium, thyroid problems, or medicine side effects.

A dementia evaluation may include medical history, medicine review, cognitive testing, lab tests, brain imaging, or referral to a specialist. Cleveland Clinic explains that diagnosis can take time because clinicians often need to rule out other conditions before deciding what is causing the symptoms.
