This can be physical, such as hitting out, or verbal, such as using abusive language. Aggressive behaviour is usually an expression of anger, fear or frustration. Remember that:

• The aggression may be due to frustration. For instance, locking the door may prevent wandering, but may also result in frustration.
• Aggressive behaviour may be a way for the person to try to get what they want.
• Activity and exercise may help prevent some outbursts.

Ways to manage aggression
Suggestions to manage aggression include:

• Approach the person slowly and in full view.
• Explain what is going to happen in short, clear statements such as: ‘I’m going to help you take your coat off’. This may help to avoid the person feeling they are being attacked and becoming aggressive in self-defence.
• Try to anticipate and respond to the person’s needs.
