Automated Detection of Early Autism May Improve Outcomes

Presently, there is no medical test to diagnose autism spectrum disorder. The disorder is usually diagnosed around 36 months based on behavior although sometimes the diagnosis occurs later in life, often in relation to learning, social, or emotional difficulties.

New research suggests genetic detection of this brain disorder could mean more timely interventions that improve life for the patient and their families.

Investigators suggest that in the near future, machine learning might be used to analyze genetic data that points to an ASD diagnosis before symptoms become obvious.

A new study describing this approach is published in the International Journal of Data Mining and Bioinformatics.

Fuad Alkoot of PAAET in Kuwait, and Abdullah Alqallaf, Ph.D., of Kuwait University, Kuwait, said that unlike other conditions, such as cancer, little attention has focused on the possibility of early genetic detection of autism.

In the study, investigators report that they have developed a four-stage computerized neural network system for testing simplified genetic data.

The system traces between 150 and 500 features present on different chromosomes and known to be associated with ASD when certain genetic patterns are present.

The team points out that symptoms in ASD increase as the child gets older and so earlier diagnosis can offer the opportunity of treatment that might ameliorate some problems associated with the condition.

At present, diagnosis relies only on expert assessment by a medical specialist. However, ambiguous symptoms in the early stages may well preclude a definitive diagnosis.

In contrast, the inclusion of genetic characteristics strongly correlated with ASD in the diagnostic process might offer a stronger diagnosis or help rule out autism in a given case.

This approach could also have implications for a better understanding of how ASD arises, particularly as current theory suggests a mixture of genetic and environmental factors are involved.

“The implementation of such a system will lead to early intervention and enable us to detect if a subject has the potential to develop autism using the subjects’ gene data, even before any behavioral symptoms start to appear,” the team reported.
