If your loved one has started wandering, you're not alone. Wandering is actually a very common part of dementia, affecting around 60% of people with the condition according to the Alzheimer's Society. Understanding why it happens can help you feel more confident about managing it and, importantly, help you realise that this behaviour isn't a reflection of your care or something you could have prevented.
When we talk about wandering in dementia, we're not referring to someone simply going for a walk or having a clear destination in mind. Dementia-related wandering is when someone moves about in a way that seems aimless, repetitive or potentially unsafe. It might involve pacing around the house, trying to leave home at inappropriate times, or becoming confused about where they are when they're out and about.
To understand wandering, it helps to think about what's happening in the brain when someone has dementia. The condition affects different areas of the brain that control memory, reasoning, spatial awareness and impulse control. These changes create a perfect storm of circumstances that can lead to wandering behaviour.
Memory and time confusion
People with dementia often experience what experts call "time shifting" - they might think they're living in an earlier period of their life. Your mum might believe she's 30 years old again and needs to collect the children from school, or your husband might think he's late for a job he retired from years ago.
Loss of spatial awareness
The brain changes in dementia can affect someone's ability to recognise familiar places or navigate their environment. Even their own home might suddenly feel unfamiliar or threatening, prompting them to search for somewhere that feels "right" to them. This explains why people sometimes wander looking for a childhood home or a place they haven't lived in for decades.
Unmet needs and discomfort
Sometimes wandering is the brain's response to physical or emotional needs that the person can no longer express clearly. They might be looking for a toilet, feeling too hot or cold, experiencing pain, or simply feeling restless and needing physical activity. The wandering becomes their way of trying to solve a problem they can't articulate.
Following old patterns
Our brains are creatures of habit, and these patterns can persist even when memory fails. Someone who walked to work every day for 30 years might still feel compelled to make that journey, even if they retired years ago. These deeply ingrained routines can be incredibly powerful drivers of wandering behaviour.
Not all wandering looks the same, and recognising the different patterns can help you respond more effectively.
Purposeful wandering
This is when someone has a clear goal in mind, even if that goal doesn't make sense in the current context. They might be convinced they need to go to work, collect children from school, or visit a parent who died years ago. To them, this wandering has a very clear purpose, and trying to stop them can cause distress and agitation.
Restless wandering
This type of wandering often stems from anxiety, boredom or excess energy. The person might pace around the house, walk the same route repeatedly, or seem unable to settle. It's often worse in the late afternoon or evening - a phenomenon known as "sundowning" that affects many people with dementia.
Exit-seeking behaviour
Some people become fixated on doors, windows or gates, constantly trying to leave their current environment. This might be because they don't recognise where they are or because they're responding to an internal need to find somewhere that feels more familiar or safe.
Trailing or shadowing
This involves following a particular person (often the main carer) everywhere they go. Whilst not traditional wandering, it can be exhausting for carers and often stems from anxiety about being left alone or forgotten.
Wandering behaviour doesn't usually appear overnight. There are often subtle signs that can help you prepare and put safety measures in place before the behaviour becomes more pronounced.
Changes in sleep patterns
People who later develop wandering behaviour often start showing disrupted sleep patterns first. They might wake frequently during the night, get up very early or seem restless when they should be sleeping.
Increased anxiety about time or schedules
You might notice your loved one becoming more concerned about being late, missing appointments or needing to be somewhere at a particular time. This anxiety can be a precursor to the restless movement that characterises wandering.
Confusion about familiar places
Getting lost in previously familiar environments - even their own home - can be an early sign. They might ask where they are when they're in their own living room or seem unsure about which door leads to the bathroom.
Restlessness and pacing
Before wandering extends outside the home, you might notice increased pacing indoors, difficulty sitting still or a general sense of agitation and the need to keep moving.
Understanding when wandering is most likely to happen can help you plan your day and put additional safety measures in place during high-risk periods.
Late afternoon and early evening
Many people with dementia experience increased confusion and agitation during these hours - a phenomenon healthcare professionals call sundowning. The changing light and approaching end of the day can trigger memories of needing to go home from work or collect children from school.
During routine disruptions
Changes to normal routines can be particularly unsettling for people with dementia. Hospital visits, having visitors, or even something as simple as rearranging furniture can trigger wandering behaviour as they try to make sense of their changed environment.
When basic needs aren't met
Hunger, thirst, needing the toilet or physical discomfort can all trigger wandering as the person tries to address their needs in the only way they can. Our information on routines offers practical tips that can help reduce these triggers.
It's important to understand that wandering behaviour isn't static - it often changes as the condition progresses. In the early stages, wandering might be more purposeful and goal-directed. Someone might successfully walk to familiar places but struggle to find their way home.
As dementia progresses, wandering might become more random and aimless. The person might lose the ability to recognise danger, making their wandering more risky. They might also become more easily confused by their environment, leading to increased anxiety and more frequent wandering episodes.
In later stages, physical limitations might reduce wandering behaviour, but the urge to move might manifest in other ways, such as constant fidgeting or attempting to get up from chairs repeatedly.
Watching someone you love develop wandering behaviour can be emotionally exhausting. Many carers describe feeling like they're constantly on edge, afraid to take their eyes off their loved one or leave them alone for even a few minutes.
It's completely normal to feel frustrated, scared, guilty, or overwhelmed by wandering behaviour. These feelings don't make you a bad carer - they make you human. Many families find it helpful to connect with others going through similar experiences through support groups or online communities.
Remember that wandering isn't something your loved one is doing deliberately to upset you. They're responding to changes in their brain that they can't control. Understanding this can help reduce feelings of frustration and guilt, though it doesn't make the practical challenges any easier to manage.
Understanding why wandering happens doesn't make it less challenging to manage, but it can help you respond with more patience and develop more effective strategies. Every person with dementia is unique, and what works for one person might not work for another.
The key is to observe your loved one's patterns, try to understand what might be driving their wandering, and work with healthcare professionals to develop a management plan that keeps everyone safe whilst preserving as much dignity and independence as possible.
If you're dealing with wandering behaviour, consider setting up a Herbert Protocol form as a precautionary measure.
Remember, you're doing your best in a challenging situation and understanding the reasons behind wandering behaviour is an important step towards managing it effectively.
