Typically, symptoms are present from the early developmental years. However, in some cases, the symptoms may not be overserved till the child is older – when social demands exceed the child’s ability to cope. The symptoms often persist into adolescences and adulthood.
Persons with ASD may experience a range of the following challenges:
Difficulties in social communication
- Lack of social emotional reciprocity (e.g. maintaining conversations, expressing emotions and sharing of interests)
- Difficulties in the use of non-verbal communication to regulate social interaction (e.g. establishing appropriate eye contact, using appropriate gestures, tone, and facial expressions)
- Difficulty establishing and sustaining relationships
- Difficulties adjusting behaviours to different social contexts
- Individuals with ASD may also present with difficulties in other aspects such as anxiety, learning disabilities and eating problems.
Restricted, repetitive patterns of behaviours, interests and activities
- Stereotyped or repetitive behaviours (e.g. repetitive speech, motor movements or use of objects)
- Constant need to keep to rigid routines and rituals (i.e. may be distressed when routines are disrupted)
- Difficulty adjusting to changes
- Highly restricted and fixated interests
- Hyper- or hypo-reactivity to sensory experiences or unusual sensory interests (e.g. being hyper-sensitive to noise or being indifferent to pain, heat and cold)
With appropriate intervention, education and support, individuals with ASD can show marked improvement in their ability to live a full life and manage their challenges despite there being no cure for developmental disabilities.
The goals of managing ASD are to facilitate normal development in learning, language and social skills, reduce autism-specific behaviours such as rigidity, repetitive movements, hyperactivity, irritability and alleviate burden for the family.
For children with ASD, it is important to find an appropriate school and to use specific strategies to facilitate their learning of social and communication skills. Occupational therapy and speech therapy may also complement the child’s learning needs.
For preschoolers, developmental paediatricians, such as doctors at the KKH Department of Child Development and the NUH Child Development Unit would be able to assess these concerns.
