Obtaining Proper Diagnosis

Obtaining a diagnosis for Autism Spectrum Disorders (ASD) is a complex task that is achieved in collaboration of the child, the parents and the healthcare professionals. Sadly, there is no sole diagnostic test that can identify childhood autism. It includes different screening processes, medical tests and evaluations that seem to never end and can easily take a toll on the child and the child’s parents and caregivers.

Diagnosing autism early is important. Parents and care givers alike should keep in mind that symptoms of autism are very hard to identify since they develop gradually and could evidently be seen only when the child reaches school age. Observation of the parents is an essential part in diagnosing autism. In all tests, these observations will be repeatedly studied and asked from the parents.

According to the Center for Disease Control (CDC), there are 2 steps in obtaining autism diagnosis. These are the developmental screening process and the comprehensive diagnostic evaluation

Developmental Screening

Developmental screening begins when the child is brought to the pediatrician for a well baby check-up. It is recommended that developmental screenings be done when the child is 9, 18 and 24 or 30 months old and screenings specifically for ASD should be done when the child is 18 and 24 months old.

The developmental screening process involves answering questionnaires or filling up checklists that serves as a guide for pediatricians. These checklists are compared to the normal developmental milestones a child. Developmental milestones are a set of functional skills or age-specific tasks that most children can do at a certain age range (Boyse, K., 2010). Any deviations or delays in the manifestation of these milestones can be an early sign of autism.  

Comprehensive Diagnostic Evaluation

Comprehensive diagnostic evaluation is done when the results of developmental screening shows cause for concern such as delays in speech and communication skills or an alteration in social development is present. In this step, a hearing and vision screening, genetic testing, neurological testing, and other medical testing may be included and performed by a multi-disciplinary team of health professionals. As the results of these different tests arrive, your pediatrician may refer you to a specialist that is more equipped to handle ASD like a pediatric neurologist, psychologist, psychiatrists and different types of certified therapists appropriate for the area of concern so that your child can get the utmost care he or she deserves.

It is important to bear in mind that Autism Spectrum Disorders are still ongoing studies. Diagnostic tools and treatments are still being discovered and proven. One clinician may recommend a test while another may suggest a different type of diagnostic procedure. It is best to find a clinician who can refer you to other specialists if he finds the need for it.

Remember that a formal diagnosis is essential for a parent to be able to start helping his or her child to improving their developmental skills and behaviors and understanding autism.
