Dementia affects people in different ways and changes in the behaviour or emotional state of someone living with dementia are common. Aggressive behaviours can be: verbal, including swearing, screaming, shouting and making threats physical, including hitting out, damaging property or physical violence towards another person. These can be distressing for the person with dementia, their family, carer and friends.
