A “repeated” symptom while walking could be a warning sign of dementia. According to experts, people with the cognitive condition could be especially prone to this habit.

Dementia is a syndrome, or a group of associated symptoms, linked to the ongoing decline of the brain. Most common in people over the age of 65, it leads to problems with memory, behavioural changes, and even mobility issues.

While there is no cure yet for the condition, there is support and treatment out there to help those affected. Therefore, spotting the potential signs sooner rather than later is important.

The Alzheimer’s Society has warned that one such sign could appear when someone is walking. They might walk around “repeatedly” and could even leave the house during the night.

“A person with dementia might want to spend time walking,” the charity says. “This isn’t always a cause for concern, but it can sometimes become a problem. 

“There are ways to help the person walk safely and manage any risks. Like most people, a person with dementia may want to spend time walking. 

“Walking is good exercise and can help relieve stress and boredom. However, a person with dementia may walk repeatedly around at home or leave the house during the day or night.”

This phenomenon is sometimes referred to as “dementia wandering”. But the society has branded this an “unhelpful term” because it suggests the person is walking with no purpose.

“In fact, there will often be a reason or belief behind it,” it says. In some cases this walking could become a problem, especially if the person has difficulties with memory or can’t find their way home. 

The charity adds: “A change in walking habits can also be a sign that a person has a need that is not being met. It can be difficult to understand why the person you are caring for is walking about. 

“By exploring the reasons, you can support them with their needs and help them to remain independent and safe.” It listed the following reasons why a person with dementia might be walking about:

• Memory loss
• Confusion about the time
• Relieving pain and discomfort
• Restlessness, agitation and anxiety
• Relieving boredom
• Lack of physical activity
• Continuing a habit or interest
• Searching for a person or something from the past
• Feeling lost.

Other symptoms of dementia to look out for include:

• Memory loss
• Difficulty concentrating
• Finding it hard to carry out familiar daily tasks, such as getting confused over the correct change when shopping
• Struggling to follow a conversation or find the right word
• Being confused about time and place
• Mood changes.

The NHS says: “These symptoms are often mild and may get worse only very gradually.” If you or someone you know is displaying signs of dementia, you should speak to a GP.
