What are the first signs of dementia?

Dementia is a group of symptoms caused by changes in the brain that affect thinking and everyday function. Early changes may be subtle: a person may repeat questions, lose track of bills, struggle with a familiar recipe, misplace items in unusual places, or find conversations harder to follow. Occasional forgetfulness happens to many people, but dementia-related problems tend to persist, progress, or interfere with independence. Memory Problems can have other causes, including sleep problems, medication effects, mood disorders or medical illness, so a symptom alone does not establish dementia.

Keep a short record of examples, when they began, and how they affect work, driving, medicines or household tasks. Invite a trusted relative to share observations if the person agrees. Arrange a GP Consultation for a history, physical review, medication check and brief thinking assessment. The clinician may recommend blood tests or further assessment, including a Mental Health Assessment when mood or anxiety could be contributing. Bring a list of medicines and relevant medical history.

Arrange a routine appointment when memory or thinking changes are recurring, worsening, or affecting safety and independence. Seek urgent medical help for sudden confusion, a new severe headache, weakness on one side, trouble speaking, fainting, or a rapid change after an injury or illness; these patterns need prompt evaluation rather than being assumed to be dementia.

Could another health problem or medicine explain these changes? Which examples should we record? What assessments are appropriate now? How should we handle driving, medicines and daily safety while the cause is being explored?
