ADHD diagnosis disparities by race, gender, and income

Despite increasing awareness about attention deficit hyperactivity disorder (ADHD), research suggests that the condition is underdiagnosed among certain groups.

These disparities in ADHD diagnosis exist for many reasons, ranging from misconceptions and stereotypes about the condition to social stigma. Understanding the disparities can help people advocate for themselves or a loved one.

Read on to learn more about the disparities in ADHD diagnosis, the causes, and what professionals can do to address them.

The use of binary terms such as “male” and “female” or “men” and “women” in this article reflects the language of the sources we have used. Unless otherwise noted, it is unclear whether the research we reference included participants with expansive gender identities.

ADHD is a neurodevelopmental condition that affects several important brain functions, including focus, memory, and executive function. Executive function is the ability to plan out actions ahead of time.

Some people only have ADHD as children, while others continue to have symptoms into adulthood. Diagnosis involves an assessment from a psychologist or psychiatrist, who will perform an in-depth interview.

The assessor may also ask family members or teachers for evidence, such as rating scales for different symptoms. This can help establish that the symptoms have been consistent since childhood.

Boys are more likely than girls to receive an ADHD diagnosis. This is, in part, due to the history of ADHD research.

In the past, many researchers believed that ADHD mostly affected boys. This led to a stereotype that ADHD causes hyperactivity and “bad behavior” in boys, but does not affect girls.

However, a 2023 study mentions past research that shows while many more boys receive a diagnosis in childhood, men and women have ADHD in equal numbers as adults. This suggests that girls may be underdiagnosed.

Underdiagnosis among girls and women with ADHD can lead to a range of negative outcomes, including low self-esteem, feelings of guilt or inadequacy, and vulnerability to abusive relationships.

Similar problems also exist in the diagnosis of autism, which can coexist with ADHD.

In addition to gender disparities, there are racial and ethnic disparities in ADHD diagnosis.

A large 2023 study of elementary school children found that Black children were less likely to receive a diagnosis than white children, despite the fact that past research suggests they experience similar levels of ADHD symptoms.

A 2021 study in the United States notes an association between ADHD and economic hardship, as well as living in an unsafe neighborhood or attending an unsafe school.

Improving the disparities in ADHD diagnosis starts with education. Anyone can improve their understanding by learning about:

Because teachers observe children working on tasks for extended periods, they have unique insight that could be useful to families. They may be able to access additional training to help them understand neurodiversity and support their students.

However, it is important to note that only qualified mental health professionals can diagnose ADHD. Health professionals and organizations can reduce disparities by:

Changes in healthcare funding and policy would also make ADHD diagnosis and treatment more widely available in underserved communities.

There is strong evidence that ADHD is underdiagnosed in certain groups. However, whether it is overdiagnosed in other groups is a matter of ongoing debate.

The number of ADHD diagnoses has risen since surveys began in 1997. There are several potential explanations for this, such as:

However, because there is no reliable clinical test to diagnose ADHD, the process relies on self-reported experiences and accounts from others. This can mean the process is open to bias, cultural differences, and mistakes.

A 2021 review of past research found some evidence that ADHD may be overdiagnosed in children and teens. The authors speculate this could happen for several reasons, such as:

Some symptoms of ADHD can also resemble the symptoms of other conditions, such as bipolar disorder or anxiety, which may lead to misdiagnosis.

This review had limitations, though. For example, some of the information relied on teachers or parents reporting whether an ADHD diagnosis benefited a child, rather than asking the child themselves.

More research is necessary to determine if ADHD is overdiagnosed in any groups, and if so, whether this causes harm.

In ADHD diagnosis, there are disparities between genders, racial and ethnic groups, and people from high or low-income backgrounds.

These disparities are complex, but they are also solvable. With increased awareness, research, and access to medical expertise, healthcare professionals can begin closing the gaps in ADHD diagnoses, ensuring all with the condition have the support they need.
