Autism vs ADHD: Understanding the Difference

Attention-Deficit/Hyperactivity Disorder, or ADHD, is a disorder that interferes with brain function. Despite the label, having ADHD does not imply that you are not paying attention. Instead, it indicates that you have difficulty to controlling your focus or focusing it on particular tasks. Symptoms of ADHD include impulsive behavior, trouble focusing, and an inability to sit still. But it also gives you the capacity to “get in the zone”—that is, to focus intently on things that you truly appreciate.

ADHD symptoms can last till adulthood and usually start in childhood, often between the ages of three and six. But in other people, the disorder is not identified until much later in life. Although there isn’t a cure for ADHD, therapies including medication and behavioral therapy can help control its symptoms.

Approximately one in ten children between the ages of three and seventeen in the United States have been diagnosed with ADHD. If your child has ADHD, spend some time learning about the realities concerning the disorder and dispelling some prevalent myths about it. You can find new ways to support your child by making connections with other parents whose children have ADHD.

ADHD Symptoms in Children

Attention-Deficit/Hyperactivity Disorder symptoms are generally divided into two main categories: Inattention and Hyperactivity/Impulsivity. Every child may show different signs, and symptoms can vary from mild to severe depending on age, environment, and daily activities.

Inattention Symptoms

Children with inattentive symptoms often struggle to stay focused, organized, and attentive during tasks or conversations. These challenges can affect school performance, daily routines, and social interactions.

You may notice your child:

• Avoids tasks that require focusing for a long time
• Doesn’t pay attention to details or makes careless mistakes
• Forgets to do things they’re supposed to do
• Gets easily distracted by surrounding activities or even their own thoughts
• Has difficulty organizing toys, school supplies, or project steps
• Struggles to stay focused while listening, reading, or studying
• Frequently loses important items like school papers, books, or eyeglasses
• Appears distracted or daydreaming when someone is talking directly to them
• Starts tasks but quickly gets sidetracked and leaves them unfinished, such as homework or chores

These symptoms are often more noticeable in classrooms or structured environments where sustained attention is required.

Hyperactivity and Impulsivity Symptoms

Children with hyperactive or impulsive symptoms typically struggle to control their actions, wait patiently, or think before acting. Compared to other children their age, they may appear more energetic or restless.

You may notice your child:

• Fidgets or constantly moves their hands and feet
• Gets up when they’re expected to remain seated
• Finds it difficult to play or work quietly
• Has trouble waiting for their turn during activities or conversations
• Interrupts others or jumps into games without permission
• Runs, climbs, or jumps excessively when expected to stay calm
• Seems constantly “on the go” or overly active
• Speaks out of turn or finishes other people’s sentences
• Talks more than expected and struggles to stay quiet

A child with ADHD may frequently lose school items, interrupt others during conversations, or struggle to remain seated during class.
