ADHD and autism share several traits including challenges with emotional regulation, impulse control issues, problems with executive function, and difficulty understanding social cues. Though similarities abound and researchers are even looking for connections between them, ADHD and autism are two different conditions. However, a person may have both ADHD and autism.
Below, we’ll discuss some of the differences between ADHD and autism, along with their causes, symptoms, diagnosis, treatment, and more.

What are ADHD and Autism?

Attention Deficit Hyperactivity Disorder is a neurodevelopmental condition that makes it difficult for people to concentrate, sit still, pay attention, and control their impulsivity.
Autism is a range of neurodevelopmental conditions that result in difficulties with understanding social cues, communicating, and thinking. Autism spectrum disorder may also feature repetitive behaviors.

What are the causes of ADHD and autism?

While there are no outright causes of ADHD there are some factors that increase the risk of developing either condition.
ADHD:
  • Genetics
  • Brain injury
  • Hazardous environmental exposures by a parent during pregnancy or at a young age
  • Use of alcohol or tobacco by a parent when pregnant
  • Low birth weight
  • Premature delivery
Autism:
The same risk factors that apply to ADHD apply to autism except for brain injury. In addition to those risk factors, autism may be caused by fetal exposure to certain drugs like thalidomide or valproic acid or certain developmental genetic disorders.

What are the symptoms of ADHD and autism?

Symptoms of both ADHD and autism usually begin in childhood and may persist throughout a patient’s life.
Symptoms of ADHD include:
  • Difficulty concentrating/focusing (inattention).
  • Blurting things out or acting without thinking (impulsivity).
Symptoms of autism include:
  • Sensory challenges that make a patient under or overreactive to stimuli like light or sound.
  • Repetitive behaviors like pacing or rocking back and forth.
  • Delays in speech, lack of verbal language, or unusual speech patterns.
  • Difficulty with social communication and interactions.
Some symptoms that both ADHD and autism share:
  • Emotional immaturity: Difficulty managing feelings like anger or frustration
  • Poor focus: People with ADHD may be distracted by external things, while people with autism may be distracted by their internal thoughts.
  • Impulsivity: Acting or speaking at inappropriate times.
  • Poor social skills and difficulty making friends.
  • Executive functioning issues: Problems organizing tasks, time, and projects.
  • Learning disabilities: Having difficulty learning new skills or information.
  • Sensory difficulties: trong or weak reactions to sensory stimuli like light and sound.
Although both ADHD and autism may share some symptoms, it’s important to note that these same symptoms often have different causes depending on the condition. For example, poor social skills and difficulty making friends may arise from a lack of body language skills and imitative speech in someone with autism. While this same symptom may be due to taking control of an ADHD person.

How are ADHD and autism diagnosed?

There aren’t any medical tests for either condition, so doctors rely on interviews, observations, and evaluations of developmental behavior to diagnose patients with ADHD or autism. Doctors will rule out other possible explanations for their behaviors by asking questions and conducting various tests.
Most people are diagnosed with ADHD and autism as children, but diagnoses may still be given into adulthood. However, this usually only happens when there are cases of mild autism or ADHD.

What is the treatment for ADHD and autism?

Treatment for autism may involve medication to help patients manage specific symptoms along with a range of therapies including:
  • Speech therapy: If severe speech delays are present, speech therapy can help improve speech development.
  • Behavioral therapy: Behavioral therapy can reduce breakdowns and improve self-control
  • Occupational therapy: Occupational therapy helps autistic patients to build skills that improve their daily lives.
  • Social skills therapy: Because lack of social skills is often a symptom with autistic patients, social skills therapy can help them better develop social skills so they can more easily understand social cues and make friends.
ADHD treatment may also include medications to help reduce impulsivity and improve concentration. Patients may also receive behavioral therapy, counseling, and skills training.
