ADHD vs Autism: Overlapping Symptoms, Different Conditions
ADHD and autism spectrum disorder (ASD) have significant symptom overlap — attention difficulties, impulsivity, sensory sensitivities, social challenges. They co-occur in 50–70% of autistic individuals. Getting both diagnosed has major treatment implications.

ADHD
ADHD — F90.9
ADHD involves dysregulation of attention, impulse control, and hyperactivity driven by dopamine and norepinephrine deficits in the prefrontal cortex. Social difficulties in ADHD stem from impulsivity and inattention — not from lack of social interest or difficulty reading social cues.
Best for
- Inattention across multiple settings (school, work, home)
- Impulsivity — acting before thinking
- Hyperactivity or chronic restlessness
- Social difficulty caused by interrupting, not listening, forgetting social commitments
Not ideal if
- Primary difficulty reading social cues, understanding intentions, or relating to peers
- Restricted, repetitive interests as a core feature
Autism Spectrum Disorder
ASD — F84.0
ASD involves persistent differences in social communication, restricted/repetitive behaviors, and sensory processing. Unlike ADHD, social difficulties in ASD stem from differences in social cognition — difficulty reading facial expressions, understanding sarcasm, theory of mind differences.
Best for
- Persistent difficulty understanding social cues and nonverbal communication
- Intense, restricted interests in specific topics
- Repetitive behaviors, routines, and sensory sensitivities
- Prefer sameness and have difficulty with transitions
Not ideal if
- Attention difficulties primarily from distraction and boredom rather than social cognition differences
Our Clinical Verdict
ADHD is about attention dysregulation; autism is about social cognition and sensory processing differences. 50–70% of autistic people also have ADHD — both can be true.
The co-occurrence of ADHD and ASD was only recognized in DSM-5 (2013) — previously they couldn't be dual-diagnosed. Many adults are still living with an unrecognized ASD diagnosis after only being diagnosed with ADHD. A comprehensive psychiatric evaluation screens for both and identifies the right treatment approach for each condition's contribution to your symptoms.
Frequently Asked Questions
Can adults be diagnosed with autism?
Yes. Many adults receive ASD diagnoses in their 20s, 30s, 40s, and beyond — particularly women, who are more likely to mask autistic traits. A psychiatric evaluation that includes structured autism screening is required for adult ASD diagnosis.
What's the treatment for ADHD vs autism?
ADHD: stimulant or non-stimulant medication plus behavioral strategies. ASD: there's no medication for core ASD features, but co-occurring conditions (ADHD, anxiety, depression) are treated medically. Applied Behavior Analysis (ABA), occupational therapy, and social skills training address core ASD features.
Does insurance cover autism evaluation in Texas?
Yes. Insurance covers psychiatric evaluation for ASD. Lyte Psychiatry can screen for ASD and co-occurring ADHD as part of a comprehensive evaluation. Formal neuropsychological testing may be referred out depending on the complexity.
How do I get evaluated for ADHD or autism in Texas?
Book a comprehensive psychiatric evaluation at Lyte Psychiatry. We screen for both ADHD and ASD features alongside depression, anxiety, and other co-occurring conditions. Same-week telehealth appointments statewide.
Can stimulant medication help if I have both ADHD and autism?
Yes — stimulants treat the ADHD component in people with both conditions. They don't affect core ASD features but can significantly improve attention, impulse control, and executive function in autistic individuals with co-occurring ADHD.
