There are no medical markers for screening or diagnosis of Autism Spectrum Disorder (ASD). There are no medical tests, like a blood test or MRI to screen for the condition. Doctors observe the child’s behavior, responses note overall development and then make recommendations or diagnose.
Autism may become noticeable as early as 15 to 18 months. However, children do not receive a final diagnosis until they are around 3 years of age. Children below the age three years are usually screened for the possibility of Autism instead of a diagnosis of Autism. The purpose of the screening is to start the training and therapies. Adapt the home environment and enhance parenting style to enable the child to learn. Early identification and intervention can enable a more natural way of learning in the child.
Some people are not diagnosed until much later, especially if they speak. They may even receive a diagnosis when they are adolescents or adults. Delay may mean that people with ASD might not get the early help and support they need.
Diagnosis is important but can be reviewed from time to time. Diagnosis allows all those associated with a child to make accommodation at home and school (however such accommodation in schools may not be available uniformly). Family has time to plan for any necessary therapies and training. Families also have to make previsions financially and plan for future support systems.
