Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental condition that affects millions of adults worldwide. While it is often diagnosed in childhood, many individuals reach adulthood without a diagnosis. This can lead to years of unexplained challenges in managing time, staying organized, setting goals, and maintaining relationships. If you’re wondering whether you might have ADHD, taking a self-assessment or ADHD quiz can be a helpful first step in identifying possible symptoms.

The Sterling Institute of Neuropsychology and Behavioral Health in Connecticut offers an online ADHD Assessment designed to provide you with insights into your behaviors and symptoms that may be indicative of ADHD.

It’s important to note that this quiz is not a substitute for professional diagnosis. Instead, it serves as a tool to help you understand whether your experiences align with those commonly reported by adults with ADHD. 

If you are concerned about your symptoms or wish to seek treatment, contact Sterling Institute today to learn more about our cutting-edge ADHD treatment program, accessible both nationally and internationally for children and adults.

What is ADHD?

Attention-deficit/hyperactivity disorder (ADHD) is a chronic neurodevelopmental disorder that manifests as persistent patterns of inattention, hyperactivity, and impulsiveness. This disorder affects the brain’s executive functions, critical for planning, focusing, and managing time and tasks.

ADHD is associated with structural and functional differences in the brain, particularly in areas such as the prefrontal cortex and basal ganglia. These regions are involved in executive functions and self-regulation. Neurotransmitter imbalances, especially in dopamine and norepinephrine, also play a significant role in ADHD symptoms. Genetic factors contribute significantly to the development of ADHD, with studies indicating a strong hereditary component.

Symptoms of ADHD 

Individuals with ADHD may experience a range of symptoms, including:


Individuals with ADHD often exhibit inattention, which can manifest in the following ways:

  • Lack of Focus: Difficulty sustaining attention on tasks or play activities, frequently shifting from one activity to another.
  • Careless Mistakes: Making errors in schoolwork, work, or other activities due to not paying attention to details.
  • Disorganization: Trouble organizing tasks and activities, leading to missed deadlines and poor time management.
  • Forgetfulness: Frequently forgetting daily activities, such as appointments or chores.


Hyperactivity in ADHD can present as:

  • Restlessness: Inability to stay still for extended periods, often fidgeting or tapping hands and feet.
  • Excessive Talking: Talking more than usual, often at inappropriate times.
  • Inability to Stay Quiet: Difficulty engaging in activities quietly, such as playing or reading.


Impulsiveness involves:

  • Hasty Actions: Acting quickly without thinking about the consequences can result in risky behaviors.
  • Interrupting Others: Frequently interrupting or intruding on others’ conversations or activities.
  • Difficulty Waiting: Struggling to wait for one’s turn in various situations, such as during conversations or in line.

Common Challenges Faced by Adults with ADHD

According to recent data from 2021, ADHD affects approximately 8 million adults each year, with the majority of those individuals remaining undiagnosed and untreated. For those with ADHD, whether they are aware of the diagnosis or not, related symptoms can present significant challenges in various areas of an adult’s life. Here are some of the common difficulties:

Work-Related Challenges

  • Difficulty Following Directions: Trouble understanding and executing tasks as instructed can lead to frequent misunderstandings and errors.
  • Organizational Issues: Adults with ADHD often struggle to keep track of tasks, deadlines, and responsibilities, making it hard to stay organized.
  • Procrastination: Frequently delaying tasks results in missed deadlines and incomplete work, contributing to stress and poor performance.
  • Job Performance: ADHD is well-documented to be associated with lower job performance and frequent job changes due to the inability to meet expectations. These job performance issues can significantly affect the careers of adults with ADHD.

Relationship Challenges

  • Communication Issues: Difficulty listening and maintaining conversations can strain relationships.
  • Impulsiveness: Acting without considering consequences can lead to conflicts.
  • Emotional Regulation: Difficulty managing emotions can result in mood swings and arguments.

Academic Challenges

  • Poor Academic Performance: History of underachievement and more frequent disciplinary actions in school.
  • Higher Dropout Rates: Increased likelihood of dropping out of school, repeating grades or courses, and not completing degrees at the university level.

Social Challenges

  • Low Self-Esteem: Constantly struggling to meet expectations can lead to feelings of inadequacy.
  • Substance Abuse: Research demonstrates a higher prevalence of substance abuse for individuals with non-managed ADHD. 
  • Driving Issues: Increased likelihood of driving violations and accidents.

Treating Adult ADHD

Managing ADHD in adults effectively often requires a comprehensive approach that includes therapy, medication, and lifestyle changes.


Cognitive-behavioral therapy (CBT) is particularly effective for adults with ADHD. CBT helps individuals develop practical skills for managing symptoms, such as time management, organization, and problem-solving. It also addresses related issues like low self-esteem, anxiety, and emotional regulation. Behavioral coaching is another therapeutic approach that provides structured support for creating routines, setting priorities, and breaking tasks into manageable steps.


Medications can be highly effective in reducing ADHD symptoms by regulating neurotransmitter levels in the brain. Commonly prescribed medications include:


  • Adderall
  • Ritalin
  • Vyvanse
  • Concerta


  • Strattera (atomoxetine)
  • Wellbutrin (bupropion, often used off-label)

These medications help improve focus, attention, and impulse control by increasing levels of dopamine and norepinephrine.

Lifestyle Changes

Implementing certain lifestyle adjustments can significantly enhance the management of ADHD symptoms:

  • Healthy Diet: A balanced diet rich in essential nutrients supports overall brain health and can improve concentration and energy levels.
  • Regular Exercise: Physical activity helps reduce hyperactivity and impulsiveness while enhancing mood and focus.
  • Adequate Sleep: Ensuring sufficient, quality sleep is crucial, as sleep deprivation can exacerbate ADHD symptoms.
  • Mindfulness and Relaxation Techniques: Meditation and deep breathing exercises can help improve focus and reduce stress.
  • Support Groups: Joining support groups can provide emotional support and practical advice from others with ADHD, fostering a sense of community and shared experience.

Combining these treatment approaches—therapy, medication, and lifestyle changes—often yields the best results. Working with a healthcare provider to develop a personalized treatment plan ensures effective management of ADHD symptoms and improves overall quality of life.
