In the first part of this series, we explored the process of diagnosing ADHD in children, adolescents, and adults. This article will delve into common conditions that can mimic ADHD symptoms. This is not an exhaustive list but aims to highlight some prevalent issues that may lead individuals to believe they have ADHD, emphasizing the importance of evaluation by a trained professional.
ADHD, a brain development disorder, typically begins in childhood, but often goes unnoticed until the individual can no longer manage the challenges associated with it. ADHD symptoms include difficulties with attention, concentration, organization, executive function, hyperactivity, restlessness, and impulse control. These symptoms can impact academic and professional performance, as well as interpersonal relationships.
Common Conditions That Mimic ADHD
Anxiety disorders often mimic ADHD. For instance, concentration issues or a mind going blank are core features of generalized anxiety. Social anxiety can cause individuals to struggle with thinking of what to say during meetings, performances, or exams. Obsessive-compulsive disorder can lead to concentration difficulties due to obsessive thoughts. Anxiety can also cause restlessness and fidgetiness, similar to ADHD.
Depression can also resemble ADHD, with concentration problems being a core feature of major depressive disorder. Individuals with depression may also exhibit low motivation, which can mimic the executive function challenges experienced by those with ADHD.
Autism, another brain development difference, can appear similar to ADHD. Individuals with autism often struggle with impulse control, and their behaviors can seem superficially similar to those of individuals with ADHD. For instance, both might find it challenging to know when it's their turn to speak and may struggle with socialization.
Cannabis (i.e., marijuana, "weed") use can also cause symptoms similar to ADHD, such as concentration and memory problems. Individuals who use cannabis and suspect they might have ADHD may benefit from ceasing cannabis use and observing if symptoms improve over a few months. Alcohol and other recreational substances can also cause symptoms that mimic ADHD.
Hearing problems may also be mistaken for ADHD. If someone struggles to hear speech, they may have difficulty attending to and understanding it, leading to perceived inattentiveness.
Insufficient sleep often leads to attention and concentration problems. This could be due to a sleep disorder or lifestyle factors. In my practice area, where school and work demands are high, patients often stay up late studying or working. This can be counterproductive, as work can take longer for those who are sleep-deprived and have impaired concentration. The optimal amount of sleep for an adult or a young person might surprise you.
Other brain differences: Some individuals have brain differences that affect them in very specific ways, unlike the more general impact of ADHD. Examples include isolated executive function disorders, auditory processing disorders, receptive language disorders, or learning challenges with specific types of tasks and subjects. It's important to understand these differences rather than default to an ADHD diagnosis, as ADHD medications generally do nothelp with these specific challenges, with very few exceptions.
Problems with the environment: Sometimes, the issue lies in the environment, not the individual. All humans have limits to our attention and concentration capacities, and sometimes our environment's demands exceed those limits. A common example emerged during the COVID-19 state of emergency, where a parent had to perform a detail-focused job in a noisy home environment while also attending to childcare. Another example, which is very common where I practice in Silicon Valley, is schools placing excessive academic demands on young people. While academics are important, it's no surprise that a young person might struggle with attention and concentration if required to focus on school all day and then do homework until late at night.
The Side Effects of ADHD Medications
ADHD medications can be life-changing for those living with ADHD. However, they come with risks. For instance, people can become addicted to ADHD medications. In individuals who truly have ADHD, this risk is less significant because studies show that treating ADHD may actually reduce the odds of developing a substance use disorder. However, individuals who are erroneously treated for ADHD may develop a stimulant use disorder without receiving significant benefit.
Conclusion
ADHD is one of many causes of problems with attention, concentration, executive function, hyperactivity, and impulsivity. ADHD treatment can be very helpful, but if ADHD is not the problem, then treatment can pose unnecessary risks. Especially when seeking a diagnosis later in life, it is crucial to seek help from a trained professional such as a psychiatrist with expertise in ADHD or a neuropsychologist.
