Unit 06: Understand behaviour in the context of dementia

This unit explores behaviour in the context of dementia and, importantly, how behaviour is often a form of communication. When someone’s brain is processing information differently, words may not come easily or may not match what the person is trying to express. Behaviour can become the message. Understanding that shift helps you respond with curiosity and compassion rather than judgement.

In practice, behaviours that challenge are rarely “out of the blue”. They often have causes that can be spotted when you slow down and look for patterns. Pain, discomfort, fear, confusion, noise, tiredness, hunger, changes in routine, and unfamiliar faces can all influence how a person reacts. Past experiences matter too. Someone who lived through war, worked night shifts, or has a history of trauma may respond strongly to certain sounds, uniforms, or being approached from behind.

The links on this page guide you through common factors that shape behaviour and why it is important to search for meaning behind what you see and hear. That might mean asking: What happened just before? What has changed today? Is the person trying to tell us something? Even a small detail can be key. A person repeatedly trying to stand may be looking for the toilet, searching for someone they love, or trying to regain control in a situation that feels confusing.

You will also cover “insight impairment”, which is about a person’s reduced ability to recognise their own condition or limitations. This can affect how they respond to support. For example, someone may insist they can manage stairs alone even though they are unsteady, or they may not understand why staff are offering help with washing. When you recognise insight impairment as part of the condition, it becomes easier to respond without arguing or “correcting”, and instead focus on safety, reassurance, and dignity.

Some behaviours are linked to changes in perception and processing. Conditions such as apraxia can affect a person’s ability to carry out familiar movements, while visual agnosia can make everyday objects hard to recognise. If a person cannot identify a cup or cannot work out how to use cutlery, frustration can show up as refusal, anger, or distress. The issue is not stubbornness. It’s a genuine difficulty that needs practical adjustments.

Delusions and hallucinations are also covered in this unit, alongside the best ways to respond. These experiences can feel completely real to the person. A supportive response avoids dismissing or mocking, and instead focuses on reassurance and safety. You may need to acknowledge feelings (“That sounds frightening”) and gently redirect, rather than trying to win an argument. Calm matters. So does tone of voice.

Sleep difficulties and repetitive questions can be particularly challenging in care settings. Night-time confusion, waking frequently, or calling out can have many causes, including pain, medication effects, needing the toilet, anxiety, or a disrupted body clock. Repetitive questions are often about reassurance, not information. The person may be asking “When are we going home?” but what they need is comfort, familiarity, and a sense that they are safe.

This unit also addresses behaviour considered “inappropriate”. It’s important to approach these situations professionally and respectfully, balancing the person’s dignity with the wellbeing and safety of others. The behaviour may be linked to unmet needs, disinhibition, embarrassment, misunderstanding social cues, or feeling threatened. In a busy day centre, for example, a person might shout or use sexualised language when they feel crowded or confused. A skilled response might involve moving to a quieter space, offering a simple choice, and ensuring colleagues are supported too.

Emotional wellbeing is a key theme. Depression, anger, and anxiety can sit alongside dementia, and the changes a person experiences can be frightening. A person may grieve their independence or feel ashamed when tasks become harder. Others may become angry when they feel out of control. Recognising these emotions early, taking concerns seriously, and offering consistent reassurance can reduce distress and improve quality of life.

Support is never just about one technique. It’s about knowing the person, using clear communication, reducing triggers, and responding in a way that keeps everyone safe. For example, in a school nursery where a grandparent with early dementia comes to pick up a child, staff might notice the person becomes flustered by noise and movement. A simple adjustment—meeting them at the door, speaking slowly, and giving one instruction at a time—can prevent embarrassment and ease anxiety.

As you work through the links on this page, keep returning to one idea: behaviour is information. When you treat it as communication, you become more effective and more human in your response. That is the foundation of good dementia care—seeing the person behind the behaviour, and offering support that fits their needs in that moment.

1. Understand that behaviour is often used as a means of communication

2. Understand how to respond to behaviours associated with dementia

3. Understand why some people with dementia will need additional emotional support
