Healthy Ageing vs Mild Cognitive Impairment vs Dementia

Misplacing your keys happens at any age. Getting lost on a familiar route, or forgetting a conversation entirely, is different. Understanding where the line sits helps families know when to seek advice.

Healthy ageing

• Thinking and responding a little more slowly
• Occasional difficulty finding a word or name that comes back later
• Taking longer to learn new technology
• Everyday independence, judgement and reasoning remain intact

Mild cognitive impairment (MCI)

MCI describes changes in memory or thinking that are greater than expected for a person's age and can be measured on testing, while they still manage most daily activities independently. Some people with MCI remain stable, some improve once a treatable cause is addressed, and some go on to develop dementia. This is why early assessment matters.

Dementia

Dementia is an umbrella term for conditions where changes in thinking become significant enough to interfere with everyday life, such as managing medications, finances, cooking or getting around safely. Alzheimer's disease, vascular dementia, Lewy body dementia and frontotemporal dementia are among the most common types.

Why a baseline helps

An assessment captures a detailed snapshot of how someone is functioning today. Repeating it in 12 to 24 months shows whether things are stable or changing, which is often the most reliable way to clarify a diagnosis.
