Autism Spectrum Disorder

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by persistent deficits in social communication and social interaction, alongside restricted, repetitive patterns of behavior, interests, or activities. It is a lifelong condition manifesting in early childhood, with a wide spectrum of severity and functional ability.

The etiology is multifactorial. Genetic factors play a significant role, with heritability estimates ranging from 60% to 90%. De novo mutations, copy number variations (CNVs), and polygenic risk scores contribute to susceptibility. Environmental factors include advanced parental age, maternal immune activation, prematurity, and prenatal exposure to certain medications (e.g., valproate).

ASD involves atypical neurodevelopment, particularly in synaptogenesis, axonal connectivity, and neural pruning. Dysregulation in the prefrontal cortex, amygdala, and cerebellum is often observed. Altered neurotransmitter pathways, specifically GABAergic inhibition and glutamatergic excitation imbalances, are implicated in sensory and social processing deficits.

Global prevalence is estimated at 1 in 36 children (CDC, 2023). It is diagnosed four times more frequently in males than females, though this may reflect sex-based diagnostic biases.

• Family history of ASD
• Advanced maternal or paternal age
• Extremely low birth weight
• Genetic syndromes (e.g., Fragile X, Tuberous Sclerosis)

A. Early Symptoms

• Failure to respond to name by 12 months


• Poor eye contact


• Delayed speech/babbling


• Lack of social smiling B. Common Symptoms


• Difficulty with peer relationships


• Difficulty with social cues


• Echolalia


• Fixated interests


• Sensory sensitivities C. Advanced Symptoms


• Challenges in social pragmatics


• Difficulty with executive function


• Rigid adherence to routines


• Social withdrawal D. Emergency Symptoms


• Acute self-injurious behavior


• Severe aggressive outbursts


• Status epilepticus

Physical exams are typically normal but may reveal subtle dysmorphic features in syndromic cases, macrocephaly, or signs of self-harm. Vital signs are generally stable unless comorbid conditions exist.

A. Clinical Assessment: DSM-5-TR criteria and ADOS-2 testing.
B. Laboratory Testing: Rule out metabolic conditions.
C. Imaging Studies: MRI if neurological regression occurs.
D. Functional Tests: Hearing and vision screening.
E. Biopsy Findings: N/A.
F. Genetic Testing: Chromosomal microarray (CMA) and fragile X testing.
G. Differential Diagnosis: ADHD, Social Communication Disorder, Intellectual Disability.

Test Name: Chromosomal Microarray Analysis
Type: Blood Test
Purpose: Identify genetic abnormalities
Expected Findings: Normal or variations in copy number
Interpretation: Diagnostic for underlying genetic cause

• MRI: Used to rule out structural anomalies in cases of neurological regression.

• ADHD (difficulty with focus vs. social deficits)
• Social Communication Disorder (lacks repetitive behaviors)
• Intellectual Disability (cognitive deficits without specific ASD patterns)

Anxiety, depression, sleep disorders, gastrointestinal distress, epilepsy, and intellectual disability.

A. Lifestyle Modifications: Structured environment, visual schedules.
B. Preventive Measures: Early intervention services.
C. Medical Treatment: - Antipsychotics (Risperidone, Aripiprazole) for irritability.
D. Surgical Treatment: N/A.
E. Interventional Procedures: ABA therapy, Speech/Occupational therapy.
F. Rehabilitation: Social skills training.
G. Emergency Management: De-escalation techniques; chemical sedation if necessary for severe aggression.

Prognosis varies; early intervention (before age 3) significantly improves long-term outcomes in adaptive behavior and communication skills. Many individuals require lifelong support.

No primary prevention. Secondary prevention via universal developmental screening at 18 and 24 months.
