What is dementia?
Dementia is a term used to describe a group of symptoms that affect the brain. It is not a single disease, but a set of changes that can make everyday life more difficult.
The symptoms usually develop gradually and become worse over time. They can affect memory, thinking, language, behaviour, and the ability to do normal activities.
Common memory symptoms
One of the best-known signs of dementia is memory loss. A person may forget recent conversations, appointments, or where they have put things.
They may also repeat questions or stories without realising they have already said them. Over time, they may find it harder to remember names, dates, or familiar information.
Problems with thinking and concentration
Dementia can make it harder to concentrate or follow a conversation. Tasks that once felt simple, such as paying bills or making a cup of tea, may become confusing.
Some people struggle with planning, organising, or making decisions. They may take much longer to do things or find it difficult to solve everyday problems.
Changes in language and communication
People with dementia may have trouble finding the right words. They might pause often, use the wrong word, or lose track of what they are trying to say.
Following what others are saying can also become difficult. In some cases, this can lead to frustration or withdrawal from conversations and social activities.
Behaviour and mood changes
Dementia can affect mood and personality. A person may become anxious, low in mood, irritable, suspicious, or unusually upset.
They may also lose interest in hobbies, feel restless, or seem less confident than before. These changes can be distressing for the person and their family.
Difficulty with everyday tasks
As dementia progresses, day-to-day routines can become harder to manage. This may include getting dressed, cooking, shopping, or using the phone.
Some people may also feel confused about time or place. They might get lost in familiar areas or struggle to recognise people or surroundings.
When to seek help
Everyone forgets things from time to time, especially when tired or stressed. But if symptoms are happening often, getting worse, or affecting daily life, it is important to speak to a GP.
Early assessment can help identify the cause and rule out other conditions that may be treatable. If you are worried about yourself or someone else, do not wait to ask for advice.
