Dementia is not a single condition, but a group of disorders that affect how the brain processes memory, thinking and communication. The symptoms depend on the underlying cause, but what links them is a gradual decline in cognitive function that starts to affect everyday life.
Early changes are often mild and inconsistent, which is why they’re easy to overlook or attribute to stress, ageing or poor sleep. The key difference with dementia is that symptoms become more noticeable over time and begin to interfere with routine tasks.
What are the early symptoms of dementia?
Early symptoms of dementia usually show up across more than one area of thinking and behaviour. It’s not just about memory, it’s the combination of changes, and the impact they have on daily life, that matters.
Common early signs include:
- Memory problems that affect daily life: Not just forgetting names occasionally, but repeatedly asking the same questions, relying heavily on notes or reminders, or struggling to recall recent events.
- Difficulty following conversations or finding words: Losing track mid-sentence, pausing frequently to find the right word, or finding it harder to engage in group conversations.
- Reduced concentration and slower thinking: Taking longer to process information, follow instructions, or complete familiar tasks such as cooking or managing bills.
- Problems with planning and decision-making: Difficulty organising steps, solving simple problems, or making decisions that would previously feel straightforward.
- Changes in orientation or awareness: Becoming confused about dates, times, or places, even in familiar environments.
What separates these symptoms from normal ageing is consistency and progression. Occasional forgetfulness is common. Dementia-related symptoms tend to happen more frequently, worsen over time, and start to impact independence.If you’re noticing a combination of these changes, particularly if they’re affecting everyday tasks, it’s worth seeking a professional dementia assessment early. This helps rule out other causes (such as vitamin deficiencies, stress or medication side effects) and, if needed, allows for earlier support and treatment planning.
Early signs of dementia in men vs women
Research and clinical observation suggest that the earliest signs of dementia are broadly similar in men and women, but the way symptoms present can differ slightly between individuals. These differences are not absolute and will vary depending on the type of dementia, overall health, and personal history.
Some studies published in journals such as The Lancet Neurology have indicated that symptom patterns can differ by sex, particularly in early stages. This includes variation in how cognitive decline is expressed through behaviour, mood, and social functioning. However, dementia diagnosis is not based on gender-specific criteria, it is based on overall cognitive change and functional impact.
In practice, this means early signs may be noticed differently rather than being fundamentally different conditions in men and women.
Early signs of dementia in men
Early signs of dementia in men are more likely to present through changes in behaviour and executive function. This can sometimes be mistaken for personality change, stress, or irritability rather than a neurological issue.
Common early indicators in men can include:
- Increased irritability or frustration
- More noticeable changes in behaviour or social interaction
- Reduced ability to manage tasks that require planning or organisation
- Difficulty adapting to changes in routine or environment
Early signs of dementia in women
In women, early signs are more frequently reported through mood and emotional changes, which can sometimes overlap with symptoms of depression or anxiety.
Common early indicators in women can include:
- Low mood or persistent feelings of sadness
- Increased anxiety or emotional sensitivity
- Withdrawal from social activities or reduced confidence
- Memory concerns alongside emotional changes
It’s important to note that mood-related symptoms in women are often initially treated separately, which can delay recognition of underlying cognitive changes.
Key differences in presentation
| Area | Men | Women |
| Behaviour | More likely to show irritability or behavioural change | Less commonly behavioural in early stages |
| Mood | Mood changes may be less prominent early on | Low mood or anxiety more commonly reported |
| Functioning | Difficulties with planning and routine tasks | Memory concerns often appear alongside emotional symptoms |
| Recognition risk | Behaviour changes may be misattributed to personality | Symptoms may be attributed to stress, anxiety or menopause |
What this means in practice
While there may be patterns in how symptoms present, dementia should always be assessed based on overall cognitive change rather than gender. Early assessment is important because symptoms can overlap with other conditions such as depression, vitamin deficiencies, thyroid issues or medication side effects.
Recognising changes early, regardless of whether they appear emotional, behavioural or cognitive, allows for earlier investigation, clearer diagnosis, and more appropriate support planning.
10 common early warning signs of dementia
Early dementia rarely presents as a single obvious symptom. In most cases, it is a pattern of small but consistent changes across memory, thinking, communication and behaviour that gradually begins to affect everyday life.
Clinically, diagnosis is not based on one or two isolated incidents, but on whether these changes are persistent, progressive, and interfere with normal functioning.
If several of the signs below are present together, and particularly if they are worsening over time, it is important to seek a medical assessment.
1. Short-term memory problems that affect daily functioning
One of the earliest and most recognised signs is difficulty retaining recent information, while older memories remain relatively intact.
This can include:
- Repeating questions without realising
- Forgetting recent conversations or events
- Misplacing items in unusual places
- Needing frequent reminders for routine tasks
The key indicator is not occasional forgetfulness, but repetition and reliance on prompts in everyday life.
2. Changes in communication and finding words
Early dementia can affect the brain’s ability to retrieve and organise language.
This may appear as:
- Pausing mid-sentence to find words
- Using incorrect or vague terms
- Difficulty following group conversations
- Struggling to express complex ideas clearly
These changes often become more noticeable in social settings or when under pressure.
3. Noticeable changes in mood and personality
Mood and personality shifts can be early indicators, particularly when they are out of character and persistent.
Examples include:
- Increased anxiety, low mood or emotional sensitivity
- Reduced confidence in familiar environments
- Personality changes that seem unusual for the individual
While depression can occur independently, persistent mood changes alongside cognitive symptoms may indicate an underlying neurological cause.
4. Increased confusion in familiar situations
Confusion that appears in environments or routines that were previously familiar is a key warning sign.
This can include:
- Losing track of time or dates
- Becoming unsure about where they are
- Forgetting the purpose of an activity mid-task
- Difficulty recognising familiar surroundings
The concern is when confusion becomes frequent rather than occasional.
5. Difficulties completing normal tasks
People in the early stages of dementia may begin to struggle with tasks they have done for years without issue.
This might involve:
- Trouble following recipes or instructions
- Difficulty managing finances or bills
- Struggling to use familiar devices
- Taking significantly longer to complete routine activities
This reflects a decline in executive function (planning, sequencing, and problem-solving).
6. Loss of interest and social withdrawal
Apathy is a recognised early feature in some forms of dementia.
Signs can include:
- Reduced interest in hobbies or activities
- Avoiding social interaction
- Appearing emotionally “flat” or disengaged
- Spending more time alone without clear reason
This is often mistaken for stress, depression or tiredness.
7. Difficulties following conversations or storylines
Processing complex information can become harder, particularly when multiple pieces of information are involved.
This may appear as:
- Losing track of conversations
- Difficulty following TV programmes or books
- Forgetting key details mid-story
- Asking for repeated explanations
This reflects changes in working memory and attention processing.
8. Repetitive behaviour or questioning
Repetition is often linked to short-term memory impairment.
This can include:
- Asking the same questions multiple times
- Repeating stories within a short period
- Re-doing completed tasks (e.g. tidying, checking items repeatedly)
The individual may not remember that the behaviour has already occurred.
9. Struggling to adapt to change
Early dementia can make unfamiliar situations harder to process.
This may present as:
- Anxiety in new environments
- Resistance to changes in routine
- Difficulty learning new tasks or systems
- Increased reliance on familiar habits
A growing preference for rigid routine can be an early behavioural signal.
10. Problems with orientation and navigation
Spatial awareness can begin to decline, affecting both familiar and unfamiliar environments.
This may include:
- Getting lost in familiar places
- Difficulty following directions or routes
- Confusion when moving between locations
- Struggling with step-by-step instructions
This is linked to changes in the brain areas responsible for navigation and spatial memory.
What is the difference between dementia and typical age-related changes?
It’s important to note that memory problems don’t automatically point to dementia, as these are normal parts of ageing. There are many other conditions that have symptoms similar to dementia, such as fatigue, stress, strokes, depression, hormonal disorders, and more.
Therefore, exhibiting these symptoms does not necessarily mean you have dementia. However, if you experience several dementia symptoms, you should consider consulting with a doctor.
We have outlined some differences between the early signs of dementia and typical age-related symptoms below:
| Early signs of dementia | Typical age-related symptoms |
| Problems with communication and having a conversation | Forgetting which word to use on some occasions |
| Consistent poor judgment and decision-making | Making poor decisions occasionally |
| Frequently losing items and being unable to retrace your steps to find them | Occasionally losing things |
| Losing track of the date, season, or time of year | Temporarily getting confused about what day of the week it is, but remembering later |
What should you do if you notice the first signs of dementia in yourself or someone else?
If you or your loved one is experiencing several of the signs we have listed, and they are not improving, we recommend that you speak to a doctor.
Your doctor can refer you to a neurologist who will examine you or your loved one’s physical and mental health to determine whether the symptoms result from dementia or another cognitive problem.
A neurologist may order:
- A series of memory and mental tests
- A neurological exam
- Blood tests
- Brain imaging tests
Dementia is more common in people over the age of 65, but it can also affect younger people. Early-onset dementia can begin in the 30s to 50s.
Early diagnosis and treatment can help slow the progression of the disease and maintain mental function. Treatments may include medications, cognitive training, and therapy.
