Key Facts about Aggression
- Aggression in Angelman syndrome
-
- There have been reports for many years of aggression in Angelman syndrome.
- What is the prevalence of aggression in Angelman syndrome?
- Previous research has estimated that 7 out of 10 individuals with Angelman syndrome showed aggression. This research also revealed that an individual with Angelman syndrome is over three times more likely to display aggression compared to individuals of the same age, gender and degree of disability who does not have the syndrome. Individuals who displayed aggression were more likely to score highly on a measure of impulsivity and overactivity.
- What are the forms of aggression in Angelman syndrome?
- Common forms of aggression seen in Angelman syndrome seem to be hair pulling and grabbing, although many other forms may occur such as hitting, kicking, scratching and biting. An example of aggression in Angelman syndrome can be seen in the clip in the box above.
- When is aggression most likely to occur?
- Aggression in Angelman syndrome is more likely to occur when levels of adult attention are low. This may be because individuals are engaging in the behaviour to reinstate attention that they find rewarding or enjoyable. It may also be related to separation distress.
- Some research has indicated that individuals with Angelman syndrome are more likely to display aggression when levels of adult contact are high (i.e. during one-to-one interaction). It has been argued that aggression seen at these times may serve to maintain social contact.
