Dementia behaviour management steps: a caregiver’s guide

The core steps for managing dementia behaviours

About 90% of people with dementia experience behavioural and psychological symptoms at some point. These are known clinically as BPSD (behavioural and psychological symptoms of dementia), and they include agitation, aggression, wandering, and mood changes. The good news is that structured, evidence-based steps make a real difference.

NICE guideline NG97 sets the standard for UK dementia care: assess first, try non-pharmacological approaches before any medication, and keep care personalised. Here are the core dementia behaviour management steps every caregiver should know:

Recognise that challenging behaviours communicate unmet needs, such as pain, fear, or boredom
Conduct a structured assessment to identify triggers before intervening
Rule out physical causes: pain, infection, medication side effects, or delirium
Apply non-pharmacological interventions first, such as mobility aids and environmental changes, routine, and activities
Consider medication only when other approaches have failed and distress is severe
Build a personalised care plan and share it with everyone involved
Support yourself as a carer through respite, training, and talking therapies

Step 1: How to assess the causes of dementia behaviours

The most effective dementia behaviour management steps begin with understanding why a behaviour is happening, not just reacting to it.

The ABC method (Antecedents, Behaviour, Consequences) is the clinical tool of choice. You note what happened before the behaviour, what the behaviour looked like, and what followed. Keeping a diary for 1–2 weeks often reveals patterns that are easy to miss in the moment, such as agitation always occurring at mealtimes or during personal care.

Before trying any intervention, rule out physical causes. Pain, urinary tract infections, constipation, and medication side effects can all trigger distress in someone who cannot clearly express discomfort. A GP assessment is the right first step when behaviour changes suddenly.

Pro Tip: Ask the GP to review all medications, including non-prescription ones. Anticholinergic drugs in particular can worsen confusion and agitation in older people.

Structured multidisciplinary assessments involving family members and care staff reduce unnecessary prescribing and address root causes more effectively. Consistency matters too: differing approaches across carers increase confusion and prolong difficult behaviours.

How to de-escalate an acute behavioural episode

When a person with dementia becomes agitated or aggressive, your response in that moment shapes what happens next.

Stay calm and give them space. Avoid testing memory or correcting the person, as this causes frustration. Use simple, closed questions and mirror their body language gently. If they are sitting with their hands in their lap, do the same. It signals that you are with them, not against them.

Acknowledge their feelings directly. Saying “I can see this is difficult for you” costs nothing and often reduces distress faster than any explanation. If the behaviour continues, try redirecting their attention to something familiar or enjoyable, such as music they like. Physical activity and sensory approaches like hand massage or aromatherapy can also help calm acute episodes. For more urgent situations, the dementia emergencies guide from Kells-care covers what to do when standard approaches are not enough.

Why monitoring behavioural changes over time matters

A single observation tells you little. A pattern tells you everything.

Keep a written record of what works, even when it does not work every time. Note the date, time, setting, and who was present. Share this record with everyone who supports the person, including family members and health professionals. It can be added directly to their care notes.

Treatment and strategies should be reviewed regularly, with medication for BPSD reviewed at six weeks as standard. Monitoring also helps you spot new physical problems early, since a sudden change in behaviour often signals something medical rather than a progression of dementia itself. For practical guidance on proven dementia care strategies, Kells-care’s resources offer London-specific support.
