There is no specific cure or particular medical treatment for autism, but much can be done to maximise a child’s potential and this is key to managing the condition.
Appropriate specialist education, speech, language and behavioural therapy are all important. There are many different approaches, some of which are based around theories about possible causes of autistic spectrum disorders.
While many people feel they've achieved good results with some of these interventions, none of them is a cure-all, and many lack scientific evidence to demonstrate their benefits.
Medication is sometimes recommended when it's felt to be of benefit to the child, for example to control seizures, depression or other symptoms.
We do know that certain strategies can go along way in supporting people with ASD:

• Autistic children gain huge security from visuals, schedules and routines.
• Autistic children respond to one instruction at a time
• Autistic children only 'lock into' instructions when they are specifically addressed to them by name.
• Autistic children need to be told how to do things the 'right way', even if it seems obvious to us.
• Autistic children need somewhere to go when overwhelmed.
