Dementia affects over 900,000 people in the UK — and that number is rising. Yet early diagnosis rates remain stubbornly low, partly because the earliest signs are subtle, easy to explain away, and often attributed simply to ageing or stress. Knowing what to look for can make a meaningful difference to outcomes.
Why Early Detection Matters
While there is currently no cure for dementia, early diagnosis allows for: access to medications that slow progression in some cases, time to make important legal and financial plans, access to support services, participation in clinical trials, and — crucially — the ability to make informed choices about care while the person still has full capacity to do so.
1. Memory Loss That Disrupts Daily Life
Forgetting where you put your keys occasionally is normal. Forgetting entire conversations that took place the same day, asking the same questions repeatedly within hours, or relying heavily on reminder notes for things that previously required no notes — these patterns warrant attention.
2. Difficulty Finding Words
Tip-of-tongue moments increase naturally with age. But frequently pausing mid-sentence, substituting unusual words, or having difficulty following or participating in conversation — particularly if this represents a noticeable change — can indicate early language-area involvement.
3. Confusion in Familiar Places
Briefly losing bearings in an unfamiliar city is entirely normal. Getting confused in your own neighbourhood, your usual supermarket, or your own home is not — and should prompt a GP conversation.
4. Difficulty with Complex Tasks
Managing finances, following recipes, planning a journey, or operating familiar equipment — when these tasks that were previously routine become unexpectedly difficult or anxiety-provoking, it may indicate working memory or executive function changes.
5. Personality or Mood Changes
Increased irritability, unusual passivity, social withdrawal, increased anxiety, or uncharacteristic behaviour — particularly when they represent a clear departure from a person's longstanding character — can be among the earliest indicators of frontotemporal dementia.
6. Getting Lost on Familiar Routes
Visuospatial difficulties — the inability to judge distances or navigate familiar environments — are common in early Alzheimer's. A person who has driven the same route for 20 years suddenly becoming unable to navigate it deserves medical attention.
7–10: Further Signs
- Repeating questions or stories within the same conversation, or telling the same stories to the same people repeatedly without recognising the repetition
- Misplacing items in unusual locations — not just forgetting where you put something, but finding items in illogical places (remote control in the freezer)
- Withdrawal from hobbies without clear reason — particularly lifelong interests that previously gave joy
- Poor judgement — making uncharacteristically bad financial decisions, being unusually trusting of strangers, or neglecting personal hygiene
The presence of any one of these signs in isolation may mean nothing. A pattern of several, representing a change from previous functioning, warrants a conversation with your GP. Please don't delay.
