The features below are based on observations of a number of individuals with ACC of varying intellectual level. Therefore this information may not be applicable to everyone. The problems that family, friends or teachers notice can change or become more apparent later in childhood. The presence of seizures or other changes in the brain structure, such as cysts or cerebellar abnormalities, may alter an individual’s abilities. If an individual has a specific diagnosis, such as Aicardi syndrome, then it may be more appropriate to look at the characteristics of other individuals with the same condition.
- Delay in achieving motor, language, and cognitive milestones
- Poor motor coordination (movement e.g. walking or throwing a ball)
- Increased sensitivity to stimulation such as food textures and touch
- High tolerance to pain
- Difficulty with complex tasks, such as using language in social situations, complex reasoning, creativity, and problem solving
- Limited sophistication of humour
- Difficulty imagining the potential consequences of behaviour
- Immature play for age
- Problems in social situations such as making inappropriate comments
- A lack of awareness of the thoughts and feelings of others
- Difficulty starting conversations and keeping conversation flowing
- Difficulty identifying what a speaker is feeling from their tone of voice or facial expressions
- Difficulty distinguishing between lies and sarcasm
- Difficulty in relationships with others, such as emotional give and take
- Limited insight into their own behaviour
A number of children with corpus callosum abnormalities will have a diagnosis of autistic spectrum disorder or Asperger’s syndrome. Some children who have problems with motor coordination may be diagnosed with dyspraxia.
