**Autism Spectrum Disorder (ASD) vs. Attention-Deficit/Hyperactivity Disorder (ADHD): Key Differences*
Autism Spectrum Disorder (ASD) vs. Attention-Deficit/Hyperactivity Disorder (ADHD): Key Differences
1. Core Symptoms :
- ASD :
- Social Communication Challenges : Difficulty with social interactions (e.g., understanding nonverbal cues, maintaining eye contact), atypical speech patterns (e.g., echolalia), and delayed language development.
- Restricted/Repetitive Behaviors : Repetitive movements (e.g., hand-flapping), strict routines, intense focus on specific interests, and sensory sensitivities (e.g., aversion to textures or sounds).
- ADHD :
- Inattention : Distractibility, forgetfulness, poor task organization.
- Hyperactivity/Impulsivity : Restlessness, excessive talking, interrupting others, impulsive decisions.
2. Attention Patterns :
- ASD : May exhibit hyper-focus on specific interests, often excluding other activities.
- ADHD : Difficulty sustaining attention, especially on non-preferred tasks; attention is scattered.
3. Social Interaction :
- ASD : Struggles stem from misunderstanding social norms or nonverbal cues.
- ADHD : Social challenges may arise from impulsivity (e.g., interrupting) or inattention during conversations.
4. Executive Functioning :
- ASD : Challenges with flexibility (e.g., adapting to routine changes).
- ADHD : Issues with organization, time management, and impulse control.
5. Repetitive Behaviors vs. Hyperactivity :
- ASD : Repetitive behaviors (e.g., rocking) are self-soothing or routine-driven.
- ADHD : Hyperactivity manifests as excessive movement or fidgeting, not ritualistic.
6. Sensory Sensitivities :
- ASD : More prevalent and intense (e.g., overwhelming reactions to sensory input).
- ADHD : Less common; if present, not a core diagnostic feature.
7. Diagnostic Criteria :
- ASD (DSM-5) : Requires early-onset social-communication deficits and restricted/repetitive behaviors.
- ADHD (DSM-5) : Requires symptoms of inattention/hyperactivity-impulsivity causing impairment, present before age 12.
8. Treatment Approaches :
- ASD : Behavioral interventions (e.g., ABA), speech/occupational therapy, and support for sensory needs.
- ADHD : Stimulant medications (e.g., methylphenidate), behavioral therapy, and organizational strategies.
9. Comorbidity :
- Co-occurrence is possible, requiring careful differential diagnosis to tailor interventions.
10. Gender Presentation :
- ASD : Girls may mask symptoms through social imitation.
- ADHD : Girls often present with inattentive symptoms rather than hyperactivity.
Summary :
While both ASD and ADHD are neurodevelopmental disorders with overlapping features (e.g., executive dysfunction), ASD is defined by social-communication deficits and repetitive behaviors, whereas ADHD centers on inattention, hyperactivity, and impulsivity. Accurate diagnosis is crucial for effective treatment, especially given the potential for comorbidity.
