Adult ADHD often goes undiagnosed, leading to significant challenges in daily life. At Diligence Care Plus, we understand the importance of accurate assessment and diagnosis.
Our team utilizes cutting-edge ADHD assessment tools for adults to identify and evaluate symptoms effectively. This blog post explores the various methods and instruments used in adult ADHD evaluations, helping you understand the comprehensive approach to diagnosis and treatment.
Spotting Adult ADHD Signs
Adult ADHD often hides in plain sight. Many adults struggle with symptoms without realizing they have ADHD. Recognizing these signs can be life-changing.
The Attention Puzzle
Adults with ADHD often find it hard to stay focused. They might start tasks but struggle to finish them. At work, they might miss deadlines or make careless mistakes. At home, they might forget to pay bills or lose important items.
A study by the National Institute of Mental Health found that 4.4% of adults in the U.S. have ADHD (about 10 million adults). Many of them don’t know they have it.

The Restless Mind
Hyperactivity in adults doesn’t always mean bouncing off the walls. It can show up as:
- Excessive talking
- Feeling restless or on edge
- Racing thoughts
- Fidgeting or squirming
These symptoms can make it hard to relax or sit still for long periods.
Impulsivity and Its Consequences
Adults with ADHD often act without thinking. This can lead to:
- Reckless driving
- Substance misuse
- Inappropriate comments
- Hasty decisions at work
Impulsivity and emotional dysregulation associated with untreated ADHD can lead to risky behaviors, endangering the individual and others.
Emotional Rollercoaster
ADHD can make emotions intense and hard to control. Adults with ADHD might:
- Have sudden outbursts of anger
- Feel easily frustrated
- Experience mood swings
- Have low self-esteem
These emotional challenges can impact personal and professional relationships.
Time Management Troubles
Many adults with ADHD struggle with time management. They might:
- Consistently run late for appointments
- Underestimate how long tasks will take
- Procrastinate on important projects
- Feel overwhelmed by deadlines
These difficulties can lead to stress and affect job performance.
If you notice these signs in yourself or a loved one, it’s important to seek professional help. A thorough assessment by a qualified healthcare provider (like Dr. Bolanle Oluwadara, MD) can provide clarity and open the door to effective treatment options. The next section will explore the various diagnostic tools used to assess adult ADHD.
How We Diagnose Adult ADHD
At Diligence Care Plus, we employ a multi-faceted approach to diagnose adult ADHD. Our methods are thorough and evidence-based, ensuring accurate assessments for our patients.
Comprehensive Questionnaires
We start with standardized rating scales. One example is a scale that is just six questions long: 4 for inattentive symptoms and 2 for hyperactive-impulsive symptoms. The questions are scored based on the frequency of symptoms.
Another useful questionnaire is the Conners’ Adult ADHD Rating Scales (CAARS). This tool helps us assess ADHD symptoms and their impact on daily life. It effectively identifies inattention and hyperactivity-impulsivity symptoms.
In-Depth Clinical Interviews
Our specialists, including Dr. Bolanle Oluwadara, MD, conduct thorough clinical interviews. These typically last 1-2 hours and cover medical history, family history, and current symptoms. We focus on how ADHD symptoms affect work, relationships, and overall quality of life.
Cognitive Performance Testing
We use computerized tests to measure attention, impulsivity, and processing speed. One such test is the Test of Variables of Attention (TOVA). This computerized neuropsychological assessment is designed to objectively measure a person’s attention and impulsivity.
Ruling Out Other Conditions
ADHD symptoms can overlap with other disorders. We conduct a comprehensive medical examination, which might include blood tests to check for thyroid issues or other medical conditions that could mimic ADHD symptoms.
We also screen for co-existing conditions like anxiety and depression. The National Comorbidity Survey Replication found that 47.1% of adults with ADHD have co-existing anxiety disorders, and 38.3% have mood disorders.

Diagnosing adult ADHD requires a combination of tools and professional expertise. Our commitment to providing accurate diagnoses and personalized treatment plans sets us apart. The next section will explore the ADHD assessment process in more detail, including initial screening, comprehensive evaluation, and collaboration with mental health professionals.
How ADHD Assessment Works
Initial Screening
The ADHD assessment process at Diligence Care Plus starts with a brief screening. We use the Adult ADHD Self-Report Scale (ASRS-v1.1), a self-rating scale for screening for ADHD in adults in accordance with the DSM-IV criteria A. This initial step helps identify potential ADHD symptoms and determines if a comprehensive evaluation is necessary.
Comprehensive Evaluation
If the screening suggests possible ADHD, we schedule a thorough evaluation. This in-depth assessment typically lasts 1-2 hours and includes:
- A detailed clinical interview
- Review of medical and psychiatric history
- Discussion of current symptoms and their impact on daily life
- Cognitive performance tests
Our mental health professionals use standardized rating scales like the Conners’ Adult ADHD Rating Scales (CAARS) to quantify symptoms. These tools provide scores for inattention, hyperactivity/impulsivity, and an overall ADHD index. When your T-score is less than 60, it usually means you don’t have ADHD. A score higher than 60 may indicate ADHD, and a T-score higher than 70 means your ADHD symptoms are more severe.

Multiple Information Sources
We collect information from various sources to create a complete picture of the patient’s condition. This approach includes:
- Self-report questionnaires
- Input from family members or partners
- School or work performance records
- Previous medical records
This comprehensive view helps us understand how ADHD symptoms manifest in different areas of a patient’s life.
Differential Diagnosis
Our team carefully considers alternative explanations for symptoms. We screen for conditions that may mimic or co-exist with ADHD, such as:
- Anxiety disorders
- Depression
- Bipolar disorder
- Learning disabilities
- Sleep disorders
In some cases, we recommend additional tests or referrals to rule out these conditions.
Collaborative Decision-Making
The final step involves a collaborative discussion among our mental health professionals. Our team members review all the gathered information to reach a consensus. If an ADHD diagnosis is confirmed, we develop a personalized treatment plan (which might include medication, therapy, lifestyle changes, or a combination of approaches).
