Coping with dementia behaviour changes
Dementia can have a big effect on someone. They may fear the impact of the loss of memory and thinking skills, and also the loss of who they are. They may not understand what's happening around them or to them. This can affect their behaviour.
Common changes in behaviour
In the middle to later stages of most types of dementia, a person may start to experience behavioural changes.
This can be distressing for both the person living with dementia and those who care for them.
Some common changes in behaviour include:
- repeating the same question or activity over and over again
- restlessness, like pacing up and down, wandering and
fidgeting - night-time waking and sleep disturbance
- following a partner or spouse around everywhere
- loss of self-confidence, which may show as apathy or disinterest in their usual activities or appearance
If you're caring for someone who's showing these behaviours, it's important to try to understand why they're behaving like this, which is not always easy.
You may find it reassuring to remember that these behaviours may be how someone is communicating their feelings or an unmet need. It may help to look at different ways of communicating with someone with dementia.
Sometimes these behaviours are not a dementia symptom. They can be a result of frustration with not being understood or with their environment, which they no longer find familiar but confusing.
How to cope with common changes in behaviour
Although changes in behaviour can be hard to deal with, it can help to work out if there are any triggers.
For example, consider if:
- some behaviours happen at a certain time of day
- the person finds the home too noisy or cluttered
- these changes happen when a person is being asked to do something they may not want to do
Keeping a diary for one to two weeks can help identify these triggers.
If the change in behaviour comes on suddenly, the cause may be a health problem. The person may be in pain or discomfort from constipation or an infection.
Ask a GP for an assessment to rule out or treat any underlying cause.
Keeping an active social life, regular exercise, and continuing activities the person enjoys, or finding new ones, can help to reduce behaviours that are out of character.
Other things that can help include:
- reassuring them
- a quiet, calming environment
- activities that give pleasure and confidence, like listening to music or dancing
- therapies, such as animal-assisted therapy, music therapy, and massage
It's not easy being the person supporting or caring for a person with behaviour changes. If you're finding things hard, ask for support from a GP.
Repeating the same question or activity
Repeating the same question or activity may be a result of memory loss where the person cannot remember what they've said or done.
It can be frustrating for the carer, but it's important to remember that the person is not being deliberately difficult.
Try to:
- be tactful and patient
- help the person find the answer themselves, for example, if they keep asking the time, buy an easy-to-read clock and keep it in a visible place
- look for any underlying theme, such as the person believing they're lost, and offer reassurance
- offer general reassurance, for example, that they do not need to worry about that appointment as all the arrangements are in hand
- encourage someone to talk about something they like talking about, for example, a period of time or an event they enjoyed
Restlessness and fidgeting
People with dementia often develop restless behaviours, such as pacing up and down, wandering out of the home and agitated fidgeting.
Try to:
- find out why the person is restless, for example, are they trying to find the bathroom
- make sure the person has plenty to eat and drink
- have a daily routine, including daily walks
- accompany them on a walk to shops or consider tracking devices and alarm systems (telecare) to keep them safe
- give them something to occupy their hands if they fidget a lot, such as worry beads or a box of items that mean something to them
Sleep disturbance
Dementia can cause problems with the person's body clock, or sleep-wake cycle.
A person with dementia may get up repeatedly during the night, unaware that it's night time.
This can be particularly hard on carers, as their sleep is disturbed, too.
Try to:
- provide plenty of activity during the day and exposure to daylight
- make sure the bedroom is comfortable with a nightlight or blackout blinds if needed
- cut down on caffeine and alcohol in the evening
Following a partner or carer around
Dementia makes people feel insecure and anxious. They may shadow their partner or carer as they need constant reassurance they're not alone and they're safe.
They may also ask for people who died many years ago, or ask to go home without realising they're in their own home.
Try to:
- have the person with you if you're doing chores such as ironing or cooking
- reassure them that they're safe and secure if they're asking to go home
- avoid telling them someone died years ago and talk to them about that period in their life instead
Loss of self-confidence
Dementia can make people feel less confident about going out or doing other activities. This may seem like they've lost interest in people or activities they usually enjoy.
Try to:
- remember they may still be interested in an activity but feel they'll have trouble coping with it
- reassure them the activity, or getting there, will be straightforward
- explain clearly where they are going and who they may be seeing
- consider alternative activities that are simpler, or social occasions that are less crowded
Aggressive behaviour in dementia
In the later stages of dementia, some people living with dementia will develop what's known as ‘behavioural and psychological symptoms of dementia’ (BPSD).
The symptoms of BPSD can include:
- increased agitation
- aggression (shouting or screaming, verbal abuse, and sometimes physical abuse)
- delusions (unusual beliefs not based on reality)
- hallucinations (hearing or seeing things that do not exist)
These types of behaviours and psychological symptoms are very distressing for the carer and for the person with dementia.
It's very important to ask your doctor to rule out or treat any underlying causes, such as:
- uncontrolled pain
- untreated depression
- infection, such as a urinary tract infection (UTI)
- side effects of medicines
If the person you're caring for behaves in an aggressive way, try to stay calm and avoid confrontation. You may have to leave the room for a while.
If none of the coping strategies works, you should contact the person’s GP for further advice.
If you're looking after someone with dementia
Your needs as a carer are as important as the person you're caring for.
To help care for yourself:
- share your experiences with other carers on online forums, such as Alzheimer's Society's Dementia Support Forum and the Carers UK forum
- try to make some time for yourself, but if it's difficult to leave the person alone, ask if someone can be with them for a while, such as a friend, relative, or someone from a support group
- consult a GP if you're feeling low or depressed as you may benefit from counselling or other talking therapies
