Forgetting something from time to time is common. Losing your keys or temporarily blanking on someone’s name does not automatically signal a serious problem. Memory can be affected by stress, exhaustion, illness and certain medications. However, difficulties that continue, become more frequent or begin to disrupt daily life should be discussed with a doctor. If you are worried about your own memory—or changes in a loved one—your GP is a sensible place to start.
What is dementia?
Dementia describes a collection of symptoms linked to diseases that damage the brain. These conditions can affect memory, reasoning, communication and behaviour, making ordinary tasks harder to manage. Alzheimer’s disease is the leading cause, while vascular dementia develops when the brain’s blood supply is affected.
About one million people in the UK currently live with dementia. The condition is more likely as people get older, but younger adults can also be affected. Symptoms differ widely, as does the speed at which they develop.
What changes should you look out for?
Memory problems are frequently among the first signs, especially difficulty recalling recent conversations or events. A person may ask the same question repeatedly, overlook appointments or increasingly depend on reminders for things they once remembered easily.
Other possible signs include struggling to keep up with conversations, finding the right words, handling finances or carrying out familiar activities such as cooking. Some people may become confused in places they know well, or experience changes in their mood, judgement or behaviour. Memory loss is not necessarily the earliest or most prominent symptom.
What matters most is whether there has been a noticeable change from a person’s normal abilities. A rare lapse is not the same as a recurring pattern that affects everyday life. Even so, these symptoms do not always point to dementia; depression, anxiety and other medical conditions can produce similar difficulties.
What happens when you see your GP?
During an appointment, your GP is likely to ask what has changed, when you first noticed it and whether it is affecting daily activities. They may also review your overall health and any medicines you take. If you are comfortable doing so, consider bringing a trusted relative or friend who knows you well. They may be able to share useful observations and help you recall the advice given.
Initial checks can include a physical examination, a brief cognitive or memory assessment and blood tests to identify other explanations, including thyroid conditions. If dementia is still a possibility, your GP may arrange a referral to a memory clinic or specialist team.
Specialist investigations may involve more comprehensive cognitive testing and, when suitable, a brain scan to provide further information.
How can treatment and support help?
There is no cure for dementia at present, but treatment and support can make a meaningful difference. For some types of dementia, medicines may ease or temporarily stabilise certain symptoms. These
effects are not the same for everyone, and reducing symptoms does not necessarily mean that the underlying disease has been slowed. Managing additional health problems, such as depression or high blood pressure, is also an important part of care.
Care should be planned in partnership with you, with family members or carers involved if you want them to be. The plan should set out what support is available, how to obtain it and which professionals will coordinate your care. Regular reviews can help ensure that changing needs are recognised.
Simple adjustments can make daily life easier, including keeping familiar routines, using reminders and adapting the home environment. Some people may benefit from group sessions focused on memory and thinking skills. Staying connected with friends, pursuing interests and making time for enjoyable activities are also valuable.
Dementia generally progresses over time, although the experience and pace vary from one person to another. Many people continue to enjoy active lives and close relationships after receiving a diagnosis. Talking about future preferences early can help ensure that the person remains involved in decisions about their care for as long as possible.
Relatives and carers also deserve support. This may include practical guidance, opportunities to take a break and help with protecting their own physical and emotional wellbeing.
Can you reduce your risk?
No method can guarantee that dementia will be prevented. The likelihood of developing it is influenced by age, genetics and broader social factors. However, taking care of your health may help lower the risk.
Avoiding smoking, staying active, eating a varied and balanced diet and keeping alcohol within recommended limits can all support long-term health. Choose realistic activities you enjoy, such as walking, dancing or gardening. Small changes that can be maintained over time are often the best place to begin.
Have conditions including high blood pressure and diabetes checked and treated appropriately. Support is also available for depression and hearing problems, while maintaining social contact can benefit overall wellbeing.
These habits benefit both the body and the brain. They are worthwhile at every stage of life, even though they cannot eliminate the possibility of developing dementia.
Where to turn for help
If changes to memory, thinking or behaviour are causing concern, arrange an appointment with your GP. Before you go, note down specific examples, when they began and the ways they are affecting everyday life.
If you are concerned about someone else, such as a relative, raise the subject gently and offer to accompany them to an appointment.
The Alzheimer’s Society and Dementia UK provide information and support for people with dementia and those close to them. Seeking help can be difficult but it allows understanding what is happening to you and finding support for your health and care needs.
