Difference Between ADHD and Autism (With Table)

Autism and ADHD are both neurodevelopmental disorders. A lot of the physical signs of autism and ADHD are the same. It might be challenging to recognize and notice these traits in children.

Autistic individuals have difficulty understanding verbal language, which is called receptive language, and expressing their thoughts, which is called expressive language. In contrast, symptoms of ADHD include inattention and hyperactivity-impulsivity, which can interfere with functioning or development. These symptoms can be mild or severe:

ADHD vs Autism

The main difference between ADHD and Autism is that ADHD patients are frequently distracted and have difficulty focusing on one task for long periods. On the other hand, autistic patients may have a narrow variety of interests.

Difference Between ADHD and Autism

ADHD (attention deficit hyperactivity disorder) is a neurological ailment marked by chronic inattention or impulsive conduct that hinders performance and growth. Studies indicate that ADHD can run in families; it isn’t developed from environmental factors such as parenting, poverty, psychology, or social status.

Most people with ADHD have the combined subtype of ADHD, meaning they display symptoms from all three categories: inattentiveness, impulsivity, and hyperactivity.

Autism is thought of as a disorder that needs to be cured. However many autistic adults have come together to change this view. They believe that autism is not a disorder but rather an alternate way of seeing the world—a difference.

Children with autism need special care and attention. They need help developing their language, play, and social skills and finding ways to express themselves better. There are no medications for autism.

What is ADHD?

People with attention deficit hyperactivity disorder (ADHD) have trouble managing emotions. They may act impulsively, make risky decisions, have mood swings, and display aggression.

Because of their poor impulse control, some people with ADHD are at greater risk for substance abuse problems. And the symptoms of ADHD can make it harder to complete tasks that involve memory or organization — such as schoolwork and household chores.

However, many people with ADHD overcome these difficulties and succeed in school, work and relationships. Part of the reason for this is that ADHD varies significantly from person to person. Some people have predominantly inattentive ADHD; others have hyperactive-impulsive ADHD essentially. Some people have a combination of both types.

While there’s no cure for ADHD, treatment can help relieve many of the disorder’s most burdensome symptoms. These include medications, behavioral interventions, and counseling.

If you have inattentive ADHD, you might seem zoned out and can’t get your mind back on track. If you have hyperactive and impulsive ADHD, you might find sitting still or waiting your turn hard.

Children with ADHD don’t just grow out of these behaviors. They may begin to show signs early and continue to struggle throughout life. But some treatments can help.

Attention deficit disorder was once thought to affect only children. Today, we know that many adults also have attention deficit disorder. Attention deficit disorder affects an estimated 4% to 5% of the adult U.S. population.

What is Autism?

Autism is a group of neurodevelopmental disorders that involve difficulties with social interaction, communication and thought. Autism spectrum disorder (ASD) is used to describe these disorders. 

The earliest indicators of autism may appear as early as six months old, with signs such as avoiding eye contact, lack of response to their name, difficulty understanding other people’s emotions, trouble expressing their own emotions, and delayed speech development.

Autism affects each child differently. Some children have only mild symptoms, while others have more severe symptoms. There are three levels of autism spectrum disorder:

Level 1 Autism Spectrum Disorder – Requiring support: The individual has mild symptoms that interfere with everyday life but can do routine tasks independently. They may need assistance in areas such as social interaction or handling change. 

Level 2 Autism Spectrum Disorder – Requiring substantial support: The individual has moderate symptoms and needs help with most regular activities. They may be able to care for themselves but need supervision. Level 3 Autism Spectrum Disorder – Requiring very substantial support: The individual has severe symptoms affecting almost all daily life. They may require constant care and supervision.
