Autism Spectrum Disorder (ASD)

What is Autism Spectrum Disorder (ASD)?

ASD is a developmental disorder characterised by challenges in communication, social interactions, and repetitive or restrictive behaviours. It affects individuals differently, with symptoms ranging from mild to severe. While the exact cause of autism is unknown, it is believed to result from genetic and environmental factors​.

Key Characteristics of ASD

1. Communication Challenges:

• Delayed speech development or inability to speak.

• Difficulty understanding nonverbal cues like facial expressions or tone of voice.

• Repeating phrases or echolalia (repetition of others’ words).

2. Social Interaction Differences:

• Difficulty forming or maintaining friendships.

• Limited eye contact or emotional reciprocity.

• Preference for solitary activities over group play.

3. Repetitive Behaviours and Restricted Interests:

• Repeated body movements, such as hand flapping or rocking.

• Intense focus on specific topics or objects.

• Resistance to changes in routines or environments.

4. Sensory Sensitivities:

• Overreaction or underreaction to sensory inputs like lights, sounds, textures, or smells.

Symptoms Across the Spectrum

ASD symptoms often appear in early childhood and vary widely in severity. Some individuals may excel in memory, art, or mathematics but struggle with everyday communication. Symptoms are usually evident by age 2 or 3, although subtle signs may emerge earlier​.

Diagnosing ASD

1. Developmental Screenings: Conducted during paediatric check-ups to monitor developmental milestones.

2. Comprehensive Evaluations: Involve specialists like child psychologists, neurologists, or developmental paediatricians in assessing behaviour and cognitive skills.

3. Standardized Tools: Tools like the Autism Diagnostic Observation Schedule (ADOS) are commonly used for diagnosis.

Early diagnosis allows for timely interventions, which can significantly improve long-term outcomes.

Treatment and Support for ASD

While there is no cure for ASD, early interventions and therapies can help individuals thrive:

1. Behavioural and Developmental Interventions:

• Applied Behaviour Analysis (ABA): Focuses on improving communication, learning, and adaptive skills.

• Speech Therapy: Enhances communication abilities, including understanding and using language effectively.

• Occupational Therapy: Develops skills for daily living and sensory integration.

2. Educational Support:

• Individualized Education Programs (IEPs) ensure tailored learning plans in schools.

• Specialized classrooms or learning tools cater to unique needs.

3. Family and Community Support:

• Training programs for parents to aid in reinforcing therapy at home.

• Support groups to connect families with shared experiences.

4. Medication:

• While no medication treats autism itself, certain symptoms like anxiety, irritability, or hyperactivity can be managed with prescribed drugs.

What Can You Do If You Suspect ASD?

1. Consult a Healthcare Provider: Paediatricians can provide initial assessments and referrals.

2. Seek Early Intervention Services: Programs like Early Start in the U.S. are vital for children under three.

3. Educate Yourself: Learn about autism and available resources to support your loved one effectively.
