Behavioural and personality changes are common in people with dementia, stemming from neurological declines affecting various brain functions. Recognising these changes and responding thoughtfully is crucial for caregivers, as it can enhance the person with Dementia and their well-being.
Here are examples of behavioural and personality changes common in people with dementia:
- Aggression or Irritability
- Outbursts of anger, yelling, or physical aggression.
- Frustration over perceived misunderstandings or difficulty with tasks.
- Apathy or Withdrawal
- Lack of interest in activities or social interactions.
- Spending excessive time alone or appearing disengaged.
- Repetitive Behaviors
- Repeating the same question, story, or action (e.g., pacing, tapping).
- Fixating on specific words or phrases.
- Mood Swings
- Rapid changes in emotions, from happiness to anger or sadness.
- Increased sensitivity to environmental triggers.
- Paranoia or Suspicion
- Accusing others of stealing or hiding belongings.
- Fear or mistrust of caregivers or loved ones.
- Hallucinations or Delusions
- Seeing or hearing things that aren’t there.
- Believing in false realities, like thinking they’re in a different time or place.
- Wandering
- Walking aimlessly, sometimes leaving the house or getting lost.
- Restlessness, especially in unfamiliar environments.
- Compulsive or Inappropriate Behaviours
- Hoarding items or hiding objects.
- Saying or doing things that might seem socially inappropriate.
Recognizing and understanding these behaviors as part of the condition helps caregivers respond with patience, empathy, and appropriate strategies.
Why Do Behavioural Changes Occur?
Dementia often leads to losing neurons in brain areas responsible for memory, attention, and impulse control. For example:
- Frontal Lobe Impact: Loss of cells here can reduce focus, motivation, and impulse control, causing passivity, mood swings, or even rude behaviours.
- Emotional Response Changes: People with Alzheimer’s might struggle to follow conversations and can feel overwhelmed in crowded settings, which may trigger frustration or anxiety.
Moreover, behavioural changes may arise due to medical issues, such as pain or infections, that individuals with dementia might not articulate. Conditions like urinary tract infections or sleep disruptions can lead to sudden shifts in behaviour, as can certain medications.
Caregiver Responses to Behaviour
Caregivers play a vital role in managing and understanding these changes. Here are some practical strategies:
- Seek Medical Evaluation: Sudden behaviour changes may indicate an infection or a reaction to medication rather than progression in dementia.
- Understand Behaviour as Communication: Behaviours like anger or irritation might indicate that the person feels overwhelmed, uncomfortable, or scared.
- Identify Triggers: Recognize potential triggers, such as new routines or unexpected visitors, which can be distressing for someone with dementia.
- Evaluate Risk: Distinguish between hazardous behaviours, like attempting to wander unsafely, and less risky habits, such as pacing within a familiar area.
- Create Routines: Structured routines offer comfort, reduce confusion and help the person feel more at ease.
Adopt a Calm, Accepting Attitude: Behavioral changes result from brain function loss, not deliberate actions, so patience and acceptance are essential.
Using the DICE Tool for Behavioural Management
The DICE approach helps caregivers assess and respond to behaviour changes:
- D – Describe: Identify the behaviour, frequency, and risks involved.
- I – Investigate: Look for potential causes, including environmental factors or discomfort.
- C – Create: Devise a structured plan for managing the behaviour, keeping routines consistent.
- E – Evaluate: Continuously assess what works or requires adjustment, as each person’s needs may evolve.
With these strategies, caregivers can better understand and respond to the unique challenges of dementia, fostering a supportive environment that improves the quality of life for everyone involved.
Here’s a table outlining the DICE Method for managing dementia-related behaviour changes:
| Step | Aspect | Details |
|---|---|---|
| Describe | Patient | – What specific behaviours are observed? (e.g., pacing, yelling) – How does the patient feel? (e.g., anxious, frustrated) – Safety risks? |
| Caregiver | – How distressing is the behaviour for you? – Is it threatening your safety? – Is it causing emotional harm? – How do you usually respond? | |
| Environment | – Who else is present? (family, friends, strangers) – Where does it occur? (noisy room, crowded area) – When does it typically happen? | |
| Investigate | Medical Causes | – Physical issues (pain, infection, dehydration)? – Medication side effects? |
| Environmental Factors | – Overstimulation? (e.g., loud noises, bright lights) – Changes in environment? | |
| Emotional Needs | – Signs of loneliness, anxiety, or fear? – Trying to communicate a need? | |
| Create | Plan Adjustments | – Adjust environment (reduce noise, create a calm space) – Modify routines to increase predictability – Introduce comforting distractions |
| Physical Comfort | – Ensure access to water, comfortable clothing, suitable temperature | |
| Communication | – Use simple language, eye contact, calm tone – Offer reassurance through gestures | |
| Evaluate | Monitor Changes | – Has the behaviour decreased? – Are new behaviours appearing? |
| Adjust as Needed | – If the plan isn’t effective, revisit the “Investigate” step – Consult professionals for additional support if necessary |
Understanding that behavioural changes in dementia are a result of the condition, not the person, allows caregivers to respond with empathy, patience, and thoughtful strategies—ultimately improving the well-being of both the individual and those who care for them.
