What causes aggressive dementia behaviours?
Dementia can cause behaviour changes in ways that are physically or verbally aggressive.
Although many people believe that these aggressive behaviours are a symptom of dementia, there are many factors that contribute to such change. Therefore, it’s important to see beyond the behaviour and think about what may be causing it.
As a person with dementia, it can be difficult to have their basic needs met. Basic human needs such as physical, psychological and social needs are what makes a person feel valued. But when this is missed, a person can lose sense of self and independence, triggering aggressive behaviours. Here are some examples of the needs they may be seeking:
1. Physical Needs
- Pain and discomfort: thirsty, need the toilet
- Side effects from medication
- Loss of memory (e.g. not remembering the layout of home)
- Sight or hearing Loss (e.g. mistaking things they see or hear can lead to confusion and frustration)
- Delusions and hallucinations
2. Psychological Needs
- Loss of independence (e.g. not being able to do things they used to do)
- Depression
- Feeling threatened or unsettled in an environment that appears strange or unfamiliar.
- Misunderstanding the intentions of the carer can make the person with dementia feel threatened or their personal space invaded.
3. Social Needs
- Loneliness or Isolation (e.g. not feeling included in a group)
- Lack of social skills
- Boredom
- Interruption to regular routine due to visits
There are many contributing factors to aggressive behaviours in people with dementia. Therefore it is important to know the person, their preference, routine and history to support them appropriately.
In our next blog, we will discuss how to prevent aggressive dementia behaviours.
