The Hereditary Nature of ADHD

The Hereditary Nature of ADHD

More and more, women are finding out they have ADHD as adults, most often after their child is diagnosed with ADHD.  When a child is diagnosed with ADHD, the doctor will often ask if the mother or father has ADHD or recommend they get tested.

ADHD in Families

ADHD is highly hereditary and if a child has ADHD, experts say there's a 30-40% chance a parent has ADHD a well. If you're wondering what the difference is between ADHD and ADD, the terms have changed over the years.

The Evolution of ADHD Terminology

During the 1980s, the name “Attention Deficit Disorder” (ADD) was defined as attention deficit disorder with or without hyperactivity by the American Psychiatric Association (APA) in the 3rd edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM III)

In 1987, there was a revised edition of DSM III and the diagnosis changed to “Attention-Deficit Hyperactivity Disorder” (ADHD) which includes these symptoms - inattentiveness, impulsivity, and hyperactivity, but there were no sub-types of ADHD.

Many continued to use the ADD term (and still do), but it hasn't been an official term in the US since 1987.

In 2000, the DSM-IV included 3 types of ADHD

  • Inattentive Type

  • Hyperactive-Impulsive Type

  • Combined Type

The Genetic Component of ADHD

Doctor Russell Barkley, says if a child has ADHD, there’s a 25% to 35% probability that a sibling has ADHD. The genetic link is even stronger in twins- between 78% to 92%.

25-35% of parents of ADHD children are adults with ADHD, 25-50% of siblings of children with ADHD have ADHD, and 70-92% of identical twins of a child with ADHD have the disorder.


ADHD can definitely run in families.

Researches indicate that approximately 20% of mothers and nearly one-third of fathers of kids with ADHD may also have ADHD.
