Could You Be Living With Undiagnosed ADHD as an Adult?

Many misunderstandings surround what it means to live with attention deficit hyperactivity disorder. Often, people imagine a hyperactive young boy who struggles to stay seated, believing that ADHD is something children outgrow. However, ADHD is a multifaceted condition that frequently continues into adulthood, with symptoms that go beyond mere inattention or restlessness. Consequently, numerous adults who have exhibited ADHD symptoms since childhood remain undiagnosed and untreated.

“The term ADHD can be somewhat misleading,” explained Lidia Zylowska, a psychiatrist at the University of Minnesota Medical School. “Difficulty focusing is only one part of the ADHD experience.”

If you suspect you might have adult ADHD, it’s crucial to seek an evaluation promptly, as untreated ADHD can lead to various personal and professional challenges. Make sure to consult a healthcare provider who specializes in adult ADHD, as many misconceptions about the disorder persist even among medical professionals.

With this perspective, here’s a broad outline of ADHD, along with some indicators that might suggest you have an undiagnosed condition.

Struggling to create plans and follow through with them

ADHD is better understood as a disorder of executive functioning. Executive function, often referred to as the “brain’s management system,” enables us to set objectives, prioritize tasks, devise strategies, and see them through to completion, even when challenges arise.

Executive function consists of three core elements: working memory, cognitive flexibility, and inhibitory control. These components allow us to focus, prioritize, establish goals, create and adapt plans based on feedback, and ultimately achieve them. This process demands foresight, adaptability to change, and the perseverance to overcome obstacles. Individuals with ADHD often face difficulties with these aspects of executive function.

You constantly seek out new activities or experiences

ADHD is believed to stem from a shortage in the neurotransmitters dopamine and norepinephrine. To compensate, individuals with ADHD often engage in behaviors that stimulate dopamine production, leading to either physical or mental restlessness.

“Even if you don’t exhibit outward hyperactivity, I’ve yet to encounter someone with ADHD who doesn’t have a hyperactive mind, constantly seeking and craving new knowledge,” said Terry Matlen, a psychotherapist and author of The Queen of Distraction: How Women With ADHD Can Conquer Chaos, Find Focus And Get More Done, who received an ADHD diagnosis in adulthood.

ADHD is categorized into three subtypes: hyperactive-impulsive, inattentive-disorganized, and combined.

Individuals with hyperactive-impulsive ADHD often seek physical stimulation, while those with inattentive-disorganized ADHD look for mental stimulation. Those with combined ADHD experience a mix of both.

These behaviors can disrupt focus, as individuals with ADHD are either preoccupied with seeking stimulation or exhausted from suppressing their impulses. Another aspect of ADHD is hyper-focus, where a person becomes intensely absorbed in one task, neglecting other responsibilities. While this might seem advantageous, hyper-focus is hard to regulate and can result in overlooking essential tasks.

ADHD is a condition present from birth, unlike anxiety or depression, which can fluctuate over time. “ADHD is inherently a constant state; it defines how your brain operates,” Zylowska explained.

A key diagnostic criterion for ADHD is that symptoms must have been evident before the age of 12. However, due to the broad spectrum of symptoms and widespread misunderstandings, even among medical professionals, many individuals go undiagnosed during childhood.

Chronic disorganization and procrastination are common struggles

Adult responsibilities, such as maintaining a job, managing finances, raising children, and addressing personal well-being, demand strong executive functioning. For those with ADHD, challenges with organization, multitasking, procrastination, and task completion can lead to difficulties both professionally and personally.

Consequently, adults with ADHD often find themselves either underemployed relative to their skills or struggling to meet expectations in roles that align with their abilities. “We encounter individuals in their ideal careers who feel overwhelmed,” Matlen noted. “They struggle to keep up due to difficulties with multitasking, meeting deadlines, and staying focused amid distractions like phone calls or emails.”

Individuals with ADHD often encounter relationship challenges, as they may forget or find it difficult to complete essential tasks like paying bills, maintaining a clean home, or picking up their children on time. “This can create significant strain in a marriage, particularly if the non-ADHD partner is unaware of the condition or its impact,” Zylowska noted.

You might exhibit addictive tendencies

Adults who remain undiagnosed often develop various coping strategies, some of which are constructive, while many are not.

Those without treatment are at an elevated risk of engaging in addictive behaviors, often as a form of self-medication. This can include high-risk activities like car racing or extreme sports, substance abuse, or eating disorders such as binge-eating. Compulsive behaviors like excessive TV watching, prolonged gaming, or overuse of social media are also common.

As Matlen highlights, individuals with ADHD may also be drawn to highly stimulating careers. These could range from high-adrenaline roles like firefighting or emergency room work to intellectually demanding jobs that involve constant learning and problem-solving.

You might also experience anxiety or depression

Adults with undiagnosed ADHD are also highly likely to develop other mental health conditions like anxiety and depression, which can make diagnosis more challenging. In some cases, these conditions arise as a consequence of ADHD, while in others, they develop independently.

“It’s beneficial to consult a specialist familiar with adult ADHD, as they can help unravel these complexities,” Zylowska advised. A key indicator is if, after addressing anxiety and depression, an individual continues to have difficulty focusing and completing tasks.

Another consideration is when ADHD symptoms first appeared, as well as a family history of the condition, given its strong genetic component. There are instances where one sibling is diagnosed in childhood, while another, who functions more effectively, may not receive a diagnosis until adulthood.

Diagnosis and treatment are crucial 

If any of this resonates with you, it’s crucial to seek an evaluation as soon as possible. Delaying diagnosis and treatment can lead to additional challenges. With clarity, you’ll feel better and can start addressing your struggles more effectively.

Given the misconceptions surrounding adult ADHD, it’s essential to consult a specialist experienced in diagnosing adults. “If you feel that ADHD describes your experiences, it’s important to advocate for yourself and seek the right support,” Zylowska emphasized.
