Despite its significant prevalence among adults and children, there are many myths and misconceptions surrounding attention-deficit/hyperactivity disorder (ADHD). One of them is that ADHD always gets worse with age. Here, we’ll examine this myth about ADHD, share the truth on this topic, and discuss ways that people with ADHD symptoms can seek support.

Common myths and misconceptions about children and adults with ADHD

Like many mental health conditions, attention-deficit/hyperactivity disorder tends to come with its share of misconceptions. For example, some people believe that ADHD isn't a "legitimate" medical disorder, and its symptoms aren't symptoms at all but simply character traits. This can be a harmful myth for the 129 million children and adolescents and 366 million adults diagnosed with the disorder around the globe, potentially discouraging them from seeking supportive treatment.

In actuality, ADHD is recognized as a diagnosable and treatable neurodevelopmental disorder by leading healthcare authorities, such as the American Psychiatric Association, Centers for Disease Control and Prevention, and the U.S. Department of Education. 

Another common misconception about ADHD can be that it either worsens or "goes away" with age. In most cases, both are untrue. While ADHD is typically diagnosed in childhood, ADHD symptoms often persist into adulthood. However, the severity of symptoms does not normally intensify as one grows older. In other words, ADHD may persist into adulthood, but it doesn't typically get worse with age when properly treated. 

Symptoms of attention-deficit/hyperactivity disorder

The Diagnostic and Statistical Manual of Mental Disorders (DSM-V) generally recognizes three distinct types of ADHD classified according to their predominant symptoms. These subtypes are: predominantly inattentive, predominantly hyperactive/impulsive, and a combined type.

The predominantly inattentive type of attention-deficit/hyperactivity disorder

Common symptoms in a person who has the predominantly inattentive type of ADHD can include:

  • Is easily distracted by external stimuli
  • Has difficulty concentrating on tasks
  • Is often forgetful during daily activities
  • Tends to lose things needed to complete daily tasks or activities
  • Frequently makes careless mistakes when completing tasks or activities
  • Has difficulty completing tasks or following instructions
  • Has trouble organizing tasks or activities
  • Avoids tasks or activities requiring sustained mental effort
  • Appears as if they aren't listening during conversations or when engaged by others

The predominantly hyperactive/impulsive type of attention-deficit/hyperactivity disorder

Common symptoms in a person who has the predominantly hyperactive/impulsive type of ADHD can include:

  • Is regularly impatient
  • Interrupts others in conversations
  • Has difficulty taking turns or waiting in line
  • Is unable to stay seated in appropriate situations
  • Compulsively "bounces" from one activity to another
  • Has difficulty engaging in quiet activities
  • Talks excessively
  • Fidgets or taps hands and feet
  • Compulsively fidgets with objects

Combined presentation 

ADHD may also emerge as a combination of inattentive and hyperactive-impulsive types. Individuals with combined presentation ADHD might experience symptoms from both of the lists above.

Can ADHD get worse with age? Common changes in ADHD over time

Core symptoms like inattentiveness, hyperactivity, impulsivity, and emotional dysregulation in the form of stress intolerance, mood swings, and self-esteem issues can be common throughout the life cycle of ADHD. How symptoms evolve usually depends on one's developmental level, differences in functional abilities, and responsibilities and expectations as one ages. Note that untreated ADHD symptoms may worsen in a person of any age, which is one reason why seeking treatment for ADHD traits and signs can be important.

The early stages: children and adolescents with ADHD

Individuals in late elementary to early middle school often become more independent at school and in social settings. For children and adolescents with ADHD, this can create unique academic and social challenges including, but not limited to, the following: 

  • Academic decline due to inattentive symptoms and difficulty comprehending more complex instructions
  • Frequently missed deadlines and assignments due to struggles with time management and disorganization
  • Challenges with interacting socially due to problems with recognizing social cues
  • Difficulty maintaining age-appropriate peer relationships because of problems adhering to social norms and contexts
  • Problems with interpersonal relationships because of impulsive behaviors

Can ADHD get worse with age? How teenagers and young adults with ADHD may experience symptoms

As one grows into high school and young adulthood, individuals may experience many of the same struggles, but new challenges can also emerge. For example:

  • Problems managing multiple deadlines and responsibilities at work and school due to organization and time management challenges
  • Lack of impulse control, potentially contributing to risky behaviors like substance misuse and unprotected or reckless sexual encounters without considering the consequences
  • Challenges with establishing and maintaining relationships due to emotional dysregulation, difficulty reading social cues, and impulsive speech

During this time, individuals often experience significant life transitions, like moving on from academic life into the workforce, changing jobs, going through family life transitions, and more. ADHD can present unique challenges with adapting to change, transitioning between life events, making long-term plans, and setting goals. 

Despite evolving challenges, studies suggest that with proper treatment and management, ADHD prevalence in adults often declines between ages 18 to 24. 

ADHD in adults and older adults

Years of living with ADHD may give a person more opportunities to learn about common symptoms and seek a diagnosis and support. After doing so and receiving treatment, ADHD symptoms often stabilize or even decrease. It can be important to note, however, that some research indicates even if symptoms disappear entirely, brain differences associated with ADHD usually remain as one ages

Research suggests that, in general, ADHD symptoms in older adults are similar to those experienced in younger people and don’t inherently worsen just because of age. However, the risk of comorbidities—such as anxiety, depression, and substance use disorder—may increase, which could exacerbate symptoms. Difficulties with relationships and social isolation as a result are common as well. As a person continues to age, it’s also possible for them to experience cognitive decline and/or a mild cognitive impairment, which could exacerbate symptoms too.

Other factors that can influence how ADHD might change with age

Experts have varying explanations for why ADHD symptoms may change with age. A few of these are outlined below.

Early misdiagnosis

There can be many reasons why ADHD might be misdiagnosed early on. Errors in the assessment of developmental age and relative maturity and lack of symptom recognition may play a role. Research indicates that factors like gender may also impact diagnosis. 

Age of intervention

Early intervention can be essential to effective ADHD treatment. Although updated evidence may be needed, researchers posit that not only may the developing brain be more receptive to lasting modifications, but early intervention may also "bypass" or lessen the impact of factors that might complicate treatment effectiveness, like struggles with peer socialization and poor academic performance. It may also curb the development of potentially harmful coping mechanisms as one ages.

Treatment adherence and effectiveness for one’s ADHD symptoms

ADHD treatment is often a two-way collaboration between a mental health professional and their client. A thorough, consistent, regularly monitored treatment plan typically requires effort from both parties for the most favorable long-term outcome.

Environmental support

A robust and supportive network of friends, family, doctors, therapists, and peers can be crucial for successful ADHD outcomes. Without this type of support, a person’s ADHD symptoms might worsen.

Stress

Studies repeatedly suggest that people with ADHD tend to be exposed to more everyday stress on average than neurotypical people. In other words, ADHD affects stress, and stress exposure may be strongly linked to the persistence of ADHD symptoms from childhood to adulthood.

Comorbid health conditions

Comorbidities like substance use disorder, anxiety, and mood disorders can be common in adult ADHD cases. These may have a significant impact on symptom severity and frequency.

Diagnosing ADHD

Diagnosis for ADHD typically involves several steps. It may begin with a comprehensive evaluation in which a mental health professional gathers information about the individual's experiences, behavior, and symptoms. They may also want to interview a person’s parents, spouse, or family for a broader perspective on the individual's behaviors.

Behavioral assessments, such as rating scales and questionnaires, may be used to gather information about the individual's behavior across different settings, such as home and school. In many cases, a medical history and physical examination are conducted to rule out other potential causes for the symptoms and ensure that no underlying medical conditions contribute to the behavior.

Available treatments for ADHD

To treat ADHD, the approach is often multifaceted and may require a combination of interventions tailored to the individual's unique symptoms and challenges. For example, intervention for children may include parental training and education, as well as individual education plans (IEPs) to support students with ADHD in school.

ADHD can be difficult to manage at any age

Behavioral therapy, such as cognitive behavioral therapy (CBT), can be effective in managing ADHD symptoms. These types of therapies usually focus on teaching skills to help individuals manage their behavior, improve organizational skills, and cope with challenges associated with ADHD. Often in combination with therapy, stimulant medications may also be prescribed by a doctor or psychiatrist to improve attention, focus, and impulse control. Healthy lifestyle changes are recommended in many cases as well.

Finally, support groups can be worth exploring too. They can offer individuals and families affected by ADHD the opportunity to connect with others facing similar challenges and share strategies for coping and managing symptoms.

Treatment outcomes can vary, and finding the most practical combination of strategies may take some time. Regular follow-up appointments can be essential to monitor the effectiveness of treatment and make any necessary adjustments.
