Autism spectrum disorder
🧩 Autism Spectrum Disorder (ASD) is a neurodevelopmental condition affecting how people communicate, interact, and experience the world.
🌈 It is called a spectrum because every individual’s presentation is unique — ranging from subtle social differences to profound support needs.
💡 Recognising both strengths and challenges is central to good care.
🔑 Key Features of ASD
- 🤝 Social Communication Differences: Difficulty with eye contact, non-verbal cues, or back-and-forth conversations.
- 🔄 Repetitive Behaviours: Hand-flapping, echolalia, lining up objects, or rituals.
- 🎯 Restrictive Interests: Intense focus on specific topics (e.g., trains, dinosaurs, numbers).
- 🎧 Sensory Sensitivities: Over/under sensitivity to light, sound, touch, smell, or taste.
📌 For Clinicians
- 🧬 Heterogeneous condition → no single presentation, no single treatment.
- 👩⚕️ Multidisciplinary assessment (paediatrics, psychiatry, speech & language therapy, psychology).
- ⚖️ Management is tailored: therapies > medication. Drugs only for comorbidities (anxiety, ADHD, irritability).
🧪 Diagnosis
- 🧒 Developmental Screening: Routine checks in early childhood; early recognition = better outcomes.
- 🔬 Comprehensive Assessment: Clinical history, observation, caregiver input, and tools like ADOS (Autism Diagnostic Observation Schedule).
- 📖 DSM-5 Criteria:
- Social communication deficits across contexts.
- Restricted/repetitive behaviours or interests.
- Symptoms present early in development.
- Functional impairment in daily life.
🛠️ Management
- 🧠 Behavioural Interventions: Applied Behaviour Analysis (ABA), social skills training.
- 🏫 Educational Support: Individualised Education Plans (IEPs) under the UK SEND framework.
- 🗣️ Speech & Language Therapy: To build communication skills (verbal & non-verbal).
- 🖐️ Occupational Therapy: Focus on daily living skills, motor skills, sensory regulation.
- 💊 Medications: Not for ASD itself — but may help with ADHD, anxiety, aggression, or sleep issues.
🤝 Common Comorbidities
- ⚡ ADHD
- 😟 Anxiety or depression
- 🧮 Intellectual disability
- ⚡ Epilepsy (20–30%)
- 🌙 Sleep problems
- 🍽️ GI issues (constipation, reflux, abdominal pain)
📈 Prognosis
🌟 Outcomes are highly variable:
- Some individuals live independently and excel in areas of strength (e.g., maths, art, technology).
- Others require lifelong structured support.
🚀 Early recognition + tailored interventions → best chance of independence, wellbeing, and quality of life.
💡 Teaching Pearls
- 👀 "Red flag": lack of response to name, poor joint attention, or absence of pointing by 18 months → consider referral.
- 🎨 Strength-based approach: many individuals show exceptional skills in memory, pattern recognition, or creativity.
- 📣 Listen to the voice of the individual and family — they are experts in their own needs.
- 🛡️ Clinicians’ role is to support, not 'normalise' behaviour.
