What you need to know about ADHD

ADHD is commonly called a neurodevelopmental disorder by the CDC and the American medical community as a whole. ADHD symptoms & traits begin in childhood and usually last into adulthood. Among the most common neurodevelopmental disorders in childhood, ADHD affects millions of children worldwide.

Common ADHD misconceptions

Many people with ADHD are not hyperactive

The medical community currently diagnose 3 types of ADHD based on the Diagnostic and Statistical Manual of Mental Disorders (DSM) 5:

-ADHD Impulsive / Hyperactive Type
-ADHD Inattentive / Distractible Type (used to be called Attention Deficit Disorder or ADD)
-ADHD Combined Type

People with the Inattentive presentation of ADHD can show little to no signs of impulsivity or hyperactivity.

ADHD is not always obvious!

There is no clear-cut one-size fit all (or even three-sizes, one per type) way to encompass everyone with ADHD. We all have variations in the symptoms we have and their severity.

Additionally we all develop an ability to manage some of our ADHD traits. Some of us become masters at masking our ADHD tendencies, so much so the people close to us would not even know we have them.

ADHD is a real disorder

The first reference to ADHD in a medical publication was authored by Adam Weikard in 1775. More than 10,000 clinical and scientific papers on ADHD have been published since then.

Years of extensive research have already proven that there are major differences between persons with and without ADHD. It has been reported ad nauseam that ADHD can cause significant social, emotional, academic, and work-related impairments.

Most Frequently Asked Questions

What is ADHD exactly?

ADHD stands for attention deficit hyperactivity disorder. In 1987, the APA changed the name from ADD to ADHD. The brain of a person with ADHD is different from those without the condition. This brain diversity entails a lot of differences both good and bad. ADHD as a medical condition focuses on these impairments. That's why the medical community defines ADHD as a mental health disorder characterized by inattention and/or hyperactivity.

Do I have ADHD?

I have ADHD, but I've only been diagnosed at age 29! Ever since my diagnosis I've been striving to learn as much as I can about ADHD. Throughout my journey, I've uncovered that I'm far from the only one that has been misdiagnosed and/or dismissed from getting the answers I was looking for. That is why I wrote the workbook "Could It Be ADHD?" to assist people who currently are in the position I used to be in.

Is ADHD a disability?

In the United States, ADHD is considered a disability under both the Americans with Disabilities Act (ADA) and another legislation known as the Rehabilitation Act of 1973.

Because ADHD is such a complicated issue, it's not feasible to cover everything comprehensibly in one page for our ADHD brains to keep up (we do have an attention problem). We, therefore, created one page per key subject about ADHD.
