Early signs of dementia often include memory loss, difficulty with decision-making, changes in mood, confusion with time or place, and problems completing familiar tasks. Concerns about memory and thinking are common as you get older. Around 982,000 people in the UK have dementia, and that number is expected to grow to 1.4 million by 2040.
Dementia is not a single illness. Instead, it is a collection of symptoms caused by different brain diseases, including Alzheimer's disease, vascular dementia, and Lewy body dementia, that affect thinking, behavior, and daily life. These types of dementia can present differently, especially in the early stages, so family members might not initially suspect dementia. An early diagnosis allows you and your family to plan ahead and access the right care and support.
Spotting the early signs of dementia can help you seek medical advice, rule out other medical conditions, get dementia care services to support you at home, and make informed decisions about your own health. This guide explains the 10 most common early signs of dementia and what they may mean for you or your loved one.
Occasional forgetfulness can be part of normal aging, but repeated memory problems that interfere with everyday life may point to early-stage dementia.
Common dementia symptoms affecting memory include:
This type of memory loss is one of the most recognised common early symptoms. A person living with dementia may struggle with short-term recall but still remember distant memories clearly. Over time, these difficulties can affect daily tasks such as cooking, attending appointments, or managing medication. A person living with dementia may forget things more often or have difficulty recalling information that has recently been learned.
While Alzheimer's disease is the most common cause of dementia, similar memory symptoms can also be caused by a vitamin deficiency, thyroid conditions, infections, or even stress. That is why a proper dementia diagnosis and further investigation are essential.
Another of the early signs of dementia is difficulty with planning and organisation. You might notice challenges with abstract thinking, following instructions, or managing household budgets.
Warning signs include:
These changes reflect changes in cognitive function. Some people describe feeling overwhelmed by tasks that once felt simple. In early stages, these changes may be subtle but gradually increase as the disease progresses.
Certain conditions, such as vascular dementia, which is often linked to high blood pressure or previous strokes, can affect planning skills early on. In rare cases, stroke-like symptoms or sudden confusion may require urgent medical review.
A person may begin to struggle with familiar tasks such as preparing meals, driving, or using household appliances. These are not simply lapses in attention but signs that thinking processes are changing.
Examples include:
In the early stages, someone may still manage independently but take longer to complete activities. As dementia affects brain pathways, routine activities can feel confusing. This is often described as one of the clearer early-stage dementia signs and symptoms.
In some cases, normal pressure hydrocephalus or other neurological problems can cause dementia like symptoms, so medical assessment and further tests are important.
Losing track of dates, seasons, or locations is another one of the signs of dementia. You may notice confusion about where you are or how you arrived somewhere.
Common signs and symptoms include:
This can be distressing and may affect confidence in leaving the house alone. In Lewy body dementia, visual processing changes can also contribute to disorientation. As dementia progresses, orientation becomes more challenging.
Visual difficulties are sometimes overlooked but can be part of the symptoms of dementia. These are especially common in Lewy body dementia and some forms of early-stage Alzheimer's disease.
You may notice:
These changes can affect driving and safety. It is important to rule out eye problems, but persistent visual issues may signal changes in the brain. Visual disturbances can be among the less obvious early symptoms of dementia.
Language problems are another key feature of early-stage dementia. You might find it harder to find the right word, or you may forget simple words in conversation.
Typical patterns include:
In frontotemporal dementia, personality and language changes are particularly common. Communication challenges can cause frustration and impact mental health. Small changes in communication approaches can significantly improve interactions during the early stages of dementia, helping you stay connected.
Everyone misplaces belongings occasionally, but repeatedly losing items in unusual places may suggest your loved one is developing dementia.
Signs include:
This can create tension among family members and affect relationships. As thinking patterns change, people may struggle with logical reasoning. Using memory aids and maintaining routine can help reduce confusion.
Changes in judgment are often subtle at first. A person may ignore health concerns, give away money, or neglect their hygiene.
Warning signs include:
These issues are often linked to changes in the frontal areas of the brain. In frontotemporal dementia, personality changes can precede memory issues. A person living with dementia may not recognise that something is wrong, making early conversations with their doctor about their changing behaviour crucial.
Another of the early signs of dementia is withdrawing from hobbies, work, or social events. You may notice a loved one starting to lose interest in activities they once enjoyed.
This may include:
Emotional changes can be harder to identify because similar symptoms can be caused by other health conditions, including depression and anxiety. Support groups and family help can make a big difference during this stage.
Encouraging participation in meaningful activities can support independence and quality of life in people living with dementia. These changes form part of the broader psychological symptoms associated with dementia.
10. Noticeable Mood and Personality Changes
Behavioural changes are common in the early stages of dementia. You might see increased anxiety, irritability, or withdrawal. Changes in mood and emotions can be a harder sign of dementia to spot, as they overlap with common symptoms of depression, grief, or stress.
Common mood changes include:
These are part of the behavioral and psychological symptoms often linked to dementia. In some forms, such as young-onset dementia or early-onset dementia, personality changes can appear before clear memory decline. Behavioral and psychological symptoms of dementia can affect mood, interests, and personality. Changes in mood and emotions can be more difficult to identify as a symptom of dementia, as they overlap with common symptoms of depression, grief, or stress.
Different types of dementia can affect people differently, and no two people will experience symptoms in the same way. The emotional impact of a diagnosis can lead to fear and sadness for both the individual and their family.
Dementia is a collection of symptoms caused by damage to the brain from different diseases. Alzheimer's disease is the most common cause, followed by vascular dementia. Some people have mixed dementia, meaning more than one specific disease is involved.
An early diagnosis enables conversations about how to live as well as possible with the condition. It allows you to plan for the future, access support, and consider treatment options. In some cases, medication in the early stages may help slow the decline.
A proper dementia diagnosis often involves memory testing, scans, and assessment of risk factors such as family history, cardiovascular health, and other conditions like multiple sclerosis.
Many conditions can cause dementia like symptoms, including infections, depression, and vitamin deficiency. That is why medical assessment and further tests are essential before confirming dementia.
Spotting the early signs of dementia in your loved one does not automatically mean they have a permanent condition. Many symptoms can be caused by treatable medical conditions, so seeking professional advice should be your first step. When changes begin to affect safety or independence, early support can help maximise quality of life. Acting early allows you to plan, access the right care, and protect what matters most.
