What ADHD Looks Like
ADHD stands for attention deficit hyperactivity disorder. It affects attention, activity level, and impulse control. ADHD starts in childhood, though many people learn about it later as adults.
Clinicians describe the presentation of ADHD based on two groups of symptoms listed in the DSM-5:
- Inattentive
- Hyperactivity and impulsivity
A person can have one group or both.
Common ADHD symptoms include:
- Trouble staying focused
- Difficulty finishing tasks
- Losing items often
- Feeling restless
- Acting without thinking
Symptoms must appear in more than one place, such as home and school or work, and they must affect daily life.

What Autism Spectrum Disorder Looks Like
Autism spectrum disorder (ASD) affects communication, behavior, and how a person understands the world. Autism appears in early childhood, but some people get a diagnosis later.
According to the DSM-5, autism includes:
- Ongoing challenges with social communication
- Repetitive behaviors, routines, or sensory differences
Common autism signs include:
- Trouble understanding social cues
- Limited eye contact
- Sensory sensitivities (noise, texture, lights)
- Strong routines and focused interests
- Differences in how they communicate or play
Some individuals also have an intellectual disability, but many do not. Autism is a spectrum, which means each person is different.

Some people wonder, “is ADHD autism?” because the symptoms can sometimes look similar. ADHD and autism can show similar signs, but they affect the brain in different ways.
Attention:
People with ADHD struggle to stay focused. People with autism may focus deeply on certain topics but have trouble shifting attention.
Social Interaction:
People with ADHD usually understand social rules but may interrupt or appear impulsive.
People with autism may find social rules confusing or hard to read.
Communication:
Autism can affect language development and understanding of tone or body language. ADHD usually does not affect language skills.
Behavior:
Autistic individuals often rely on routine.
People with ADHD may avoid routine or struggle to keep one.
These differences help professionals separate ADHD from autism during an evaluation.

Where ADHD and Autism Overlap
Some traits can appear in ADHD vs autism. Both ADHD and ASD are neurodevelopmental disorders, and they often affect emotional regulation, planning, and social comfort.
Shared traits may include:
- Feeling overwhelmed in busy places
- Difficulty with time management

Many children with ADHD also show signs seen in autism. When both conditions appear together, it is sometimes called disorder ADHD and autism or co-occurring ADHD and ASD.
