What should you know about first signs of dementia?

The first signs of dementia are persistent changes in memory, thinking, language, or daily tasks that gradually affect everyday life. A person may repeat questions, lose track of familiar routines, struggle to find words, mismanage money, or become disoriented in a known place. Forgetfulness alone does not establish dementia, and sudden confusion needs urgent medical attention.

Dementia describes a decline in cognitive abilities that interferes with independence. Family may notice missed appointments, difficulty following a recipe, misplaced objects in unusual places, changes in judgement, or withdrawal from familiar activities. Sleep problems, depression, medicine effects, thyroid disorders, infection, hearing loss, and other conditions can affect thinking, so a structured assessment is useful.

Keep a brief record of changes, when they started, and examples from daily life. Bring a current medicine list and, if the person agrees, ask someone who knows them well to join a GP consultation. Support regular meals, hydration, sleep, hearing and vision care, and safe routines. Avoid arguing over a forgotten detail; offer calm prompts and practical help.

Arrange a medical appointment when changes persist, progress, or interfere with medication, finances, cooking, travel, or personal safety. Seek urgent help for sudden confusion, new weakness, trouble speaking, severe headache, a fall with head injury, fever, or a rapid change in behaviour. New urinary incontinence with walking or thinking changes also deserves prompt assessment.

Ask which reversible causes should be checked, whether a memory or mental health assessment is suitable, and how results will be explained. Discuss driving, work, medication organisation, home safety, consent, and who should attend follow-up. Ask what changes should trigger earlier review.
