When to worry about memory problems with dementia

Dementia can gradually affect remembering recent conversations, finding words, following familiar routines, or managing medicines and money. A person may repeat questions or lose track of time. Day-to-day variation can happen, especially with fatigue, but a marked change over hours or a few days may have another cause, such as an infection, medication effect, dehydration, or a stroke.

Write down when the change began, what happened, and whether sleep, eating, drinking, medicines, pain, or illness changed at the same time. Keep medicines in their usual labelled containers and reduce hazards such as an unattended cooker. Calm reminders, a familiar routine, good lighting, and one question at a time can support communication. Arrange a review if memory changes are gradually affecting dressing, meals, appointments, or personal safety.

Seek urgent help for sudden confusion, new weakness or numbness, facial drooping, trouble speaking, a severe new headache, seizure, collapse, fever with a sharp mental change, or immediate danger of wandering or self-harm. Contact a clinician promptly when decline is faster than expected, falls begin, hallucinations appear, or the person cannot take essential medicines safely.

Ask what change would be expected from the dementia, whether medicines or illness could be contributing, and which assessment is appropriate. Ask how to make the home safer and who to contact outside appointments if confusion worsens.
