What is Autism Spectrum Disorder (ASD)?
Autism Spectrum Disorder (ASD) is a neurodevelopmental difference that emerges in early childhood. It can affect an individual's social communication, social interaction, and regulation skills, and is often accompanied by restricted interests and repetitive behaviors.
Why is ASD Called a "Spectrum"?
ASD affects children at different levels. While some children progress more independently in daily living skills, others may require more intensive support. The term "spectrum" is used because of this wide range of characteristics and support needs.
Core Characteristics of ASD
In a diagnostic framework, ASD is addressed in two main areas:
1. Difficulties in Social Communication and Interaction
- Difficulty in initiating and maintaining reciprocal communication
- Limitations in non-verbal communication (eye contact, gestures, facial expressions)
- Challenges in establishing peer relationships and initiating play
- Responses that do not fit the context or difficulty maintaining a topic during communication
2. Restricted and Repetitive Behaviors / Interests
- Repetitive movements (rocking, hand flapping, walking on toes, etc.)
- Repetition of sounds or words (Echolalia)
- Excessive adherence to routines and difficulty adjusting to change
- Sensory differences (over- or under-reactivity to stimuli such as sound, light, or textures)
Common Signs Noticed by Families
The following symptoms do not provide a diagnosis on their own but may require consultation with a specialist:
- Avoiding eye contact or not responding to their name
- Delayed speech or regression in previously acquired skills
- Preference for being alone and lack of joint attention (not looking where someone points)
- Excessive focus on specific objects or parts of objects (e.g., spinning wheels)
- Robotic or monotone tone of voice
Diagnosis and Causes
An ASD diagnosis is made by a Child Psychiatrist or a Child Neurologist. The process involves developmental history, clinical observation, and screening tools such as the M-CHAT.
Important Information:
- There is no single cause for ASD; genetic and neurological factors are primary.
- ASD is NOT caused by parenting styles or socioeconomic conditions.
- Research has proven that there is NO link between vaccines and ASD.
The Role of the Speech and Language Therapist (SLT)
Speech and language therapy is a fundamental component in structuring communication in ASD. The SLT focuses on the following goals:
- Increasing verbal and non-verbal communication
- Supporting perspective-taking (theory of mind) and social meaning in different contexts
- Strengthening conversational skills and the exchange of ideas
- Making interaction enjoyable through play
- Working on regulation and speech intelligibility when necessary
When Should You Seek Help?
- If your child does not respond to their name
- If pointing, showing, or joint attention is absent
- If eye contact is very limited
- If there is a regression in communication skills (e.g., loss of words)
- If repetitive behaviors and extreme reactions to change are prominent
Early diagnosis and intervention play a critical role in maximizing a child's potential.
If you have any doubts, it is recommended to seek an evaluation without delay.
