    Are My Child's Speech Delays a Sign of Autism?

    True or False: Speech Delays = Autism?

    Parents become understandably anxious when a child doesn’t meet age-expected speech development milestones.  There is a delicate balance between total panic at the sign of speech delays, and taking a step-by-step approach to understanding what might be causing such delays.  How can a parent know if a speech delay should be of concern, and if it might be a sign of Autism Spectrum Disorder?  As psychiatrist Steve Dvorin says, “There are so many possibilities,” regarding underlying causes.

    Communication disorders comprise four separate disorders, according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-V).  These include:

    • Language Disorder
    • Speech Sound Disorder
    • Childhood-Onset Fluency Disorder (Stuttering)
    • and Social/Pragmatic Communication Disorder.

    As explained in the DSM-V, 

    Speech is the expressive production of sounds and includes an individual’s articulation, fluency, voice, and resonance quality.  Language includes the form, function, and use of a conventional system of symbols (i.e., spoken words, sign language, written words, pictures) in a rule-governed manner for communication.  Communication includes any verbal or non-verbal behavior (whether intentional or unintentional) that influences the behavior, ideas, or attitudes of another individual (p. 41, DSM-V).


    Without detailing the extensive criteria for diagnoses of these four disorders, compare the above definitions of speech, language, and communication with the relevant criterion of the diagnosis of ASD (and here I am picking out only those segments that are specific to speech, language, and communication):

    • Failure of normal back-and-forth conversation
    • Failure to initiate or respond to social interactions
    • Deficits in nonverbal communicative behaviors used for social interaction
    • Poorly integrated verbal and nonverbal communication
    • Abnormalities in body language
    • Deficits in understanding and use of gestures (p. 50, DSM-V)


    Five years old boy with autism not cooperating with his psychotherapist.The first essential feature of ASD (among other features), according to the DSM-V, is “persistent impairment in reciprocal social communication and social interaction” (p. 53, DSM-V).  Note the emphasis on “social.”  This is not quite the same as Language Disorder, which is associated with a failure of acquisition of language, primarily due to lack of comprehension.  Specifically, the child with Language Disorder has a lack of word knowledge and use (vocabulary) and limited sentence structure, both of which are evident in spoken and written communication.  The “social” component is not the central feature of Language Disorder, although of course it has an impact on social interaction; with ASD the social interaction deficit is central.

    While many individuals with ASD are “slow to talk” (DSM-V p. 55), this in itself does not mean that a diagnosis of ASD is appropriate; it might be totally normal for that child.  Symptoms of ASD are typically recognized in a child between ages 1 and 2.  More subtle symptoms may require longer to recognize.  Some children have a normal developmental trajectory, then rapidly and inexplicably exhibit loss of developmental gains, such as language, prior to age 3; this may be a sign of ASD.  After age 3, such a loss of language gains could be a sign of seizures or other specific neurological conditions.  

    A thorough evaluation by a medical provider is necessary to rule out any underlying medical condition that might cause a regression in language or other development, and to also rule out other disorders that may have communication-related symptoms, such as Selective Mutism, Intellectual Disability, or the communication disorders mentioned above.  More than one condition or diagnosis may be present at the same time.  A hearing loss must also be ruled out.  And, sometimes there are other quite normal reasons why a child might begin verbal communication later or on a limited basis.  What do I mean by that?

    Environment can be addressed, and stimulating language learning materials may assist a child who is slow to develop communication skills.  It can be difficult to know when/where to start.  There is nothing wrong with using a speech language milestones chart. But caution is advised.  The American Speech-Language-Hearing Association (ASHA) states very clearly: “Children develop at their own rate.”  It is easy to become anxious, and even to panic, when your child is not on top of the developmental milestones.  Perhaps even before calling your medical provider for an evaluation, you might try some of the steps suggested by ASHA for communication development.  For your pre-school or school-age child, try the Language Builder cards provided by Stages Learning to help your child develop early language skills.  

    “The earlier the intervention, the better the prognosis will be.”

    According to psychiatrist Steve Dvorin, “The earlier the intervention, the better the prognosis will be.”  So while panic is not necessary, taking reasonable investigative steps towards understanding the cause of a speech or language delay is important, as well as corrective action.  Your medical provider should be consulted.  If there is cause for concern, a more thorough evaluation may be required.  The provider will then devise a treatment plan which will likely involve the child, parents, teachers, and potentially speech therapists or other specialists.  There are many methods for addressing speech delays in a manner that builds on your relationship with your child and helps him or her develop better communication and interaction skills.  So don’t panic, take it one loving step at a time.
