As we age, our bodies and brains go through a number of changes. It can be difficult to tell if the changes that we are experiencing can just be put down to general ageing, or if they may be a sign of something more serious. This article explains the differences between normal ageing and dementia.
How Is Dementia Different From Normal Ageing?
It’s completely normal to become a bit more forgetful as we age. Changes are likely to develop around middle age, from our 40s and into our 50s and 60s. For example, as we get older, most of us will take a bit longer to remember things. We may also get more easily distracted and become less able to multi-task the way we used to in our younger years. While these changes may be frustrating, they are completely normal and nothing to worry about. These symptoms alone are not a sign of dementia.
‘Dementia’ is the term for a group of symptoms that occur when the brain becomes damaged by diseases, such as Alzheimer’s disease, or diseases of the blood vessels that can cause a stroke.
The Signs and Symptoms of Dementia
A person with dementia is likely to experience significant decline in their mental abilities, such as memory, thinking and reasoning. In order for dementia to be diagnosed by a medical professional, they will have to see that the person’s symptoms have developed enough to have a significant impact on their everyday life. For example, a person with dementia may experience problems with driving, difficulties paying bills, using their mobile phone, or remembering how often and when to take their medication.
The below table shows some of the changes for the most common types of dementia: Alzheimer’s disease, vascular dementia and mixed dementia. Other, less common types of dementia may have symptoms that are not shown below.
The table shows the possible changes that may occur due to both normal ageing and early dementia. Remember that everyone is different, and not everyone with dementia will have all of these changes. Similarly, if you are experiencing some of these symptoms, it does not necessarily mean that you have dementia; other conditions can be the reason for certain symptoms.
Speak to a medical professional if you are worried about symptoms that you are experiencing or symptoms that a loved one has. Dementia can only be diagnosed by an experienced health professional.
