Understanding ADHD Without Hyperactivity

Can someone have adult ADHD without being hyperactive and without being diagnosed as a child? The answer is yes, and it is a phenomenon that many adults are only now realizing they may be experiencing. In the 1960s, when I was a child, there were no assessments for ADHD or autism. I often found myself excluded and placed in a special educational needs school. Fast forward to now, as an adult, I am finally seeking a diagnosis, though I am almost 70 and have a few years left.

The Misunderstood Symptom of Hyperactivity

The term 'hyperactivity' is often misinterpreted as children who are constantly running around uncontrolled and unable to sit still. However, for many adults, hyperactivity manifests in a different form. Their mind is restless, impulsive, and jumping from one thought to another at an extraordinary speed. This 'hyperactive' mind makes it hard to concentrate, and they often struggle to follow the conversation or understand the train of thought of others. They may talk rapidly, causing others to feel overwhelmed and unable to keep up. They also find it challenging to fall asleep and relax mentally, even when tired.

Diagnosis in Adulthood vs Childhood

It is not uncommon for ADHD to go undiagnosed until adulthood. Situational or emotional challenges during childhood, such as major illnesses, drug problems, a parent in prison, sibling issues, or even family dysfunction, can overshadow the signs of ADHD. However, it is important to clarify that ADHD cannot develop in adulthood. It is a condition present from early childhood.

The Diagnostic Criteria for Adult ADHD

Doctors can diagnose ADHD in adults if there is clear evidence that the problems were present, severe, and impairing during childhood. This includes studying school reports, letters from school transcripts, and evidence of school suspensions or expulsions. Interviews with individuals who knew the patient in childhood, such as siblings or friends, are also crucial. ADHD is only considered if the following criteria are met:

Classic symptoms of ADHD, including hyperactivity, impulsivity, lack of self-control, major focus issues, and extreme distraction. Severe and obvious symptoms that are visible to those who work with or around the individual. Continuous presence of symptoms from childhood, clearly evidenced through records and observer reports. Significant life impairment and severe impact on the person's ability to function.

If any of these criteria are not present, the symptoms are more likely to be a result of other issues such as sleep problems, food intolerances, high stress, or a typical outgoing personality rather than ADHD.

My Personal Journey

When I was young, there were no assessments for ADHD or autism. I was excluded and placed in a special educational needs school. Today, I am almost 70 and am only now seeking a diagnosis. The opportunity to be assessed has recently arisen. When I am asked why I need a diagnosis at this age, my response is often met with curiosity. The answer is that ADHD can present differently in adults, and a diagnosis can provide much-needed understanding and support.

Adults with ADHD without hyperactivity often have a different set of challenges. Their condition can go unnoticed, leading to years of struggle without the proper supports and interventions. My journey is a testament to the fact that ADHD can develop and be recognized well into adulthood, even when it does not manifest with high levels of hyperactivity.
