From the Guidelines

A full ADHD evaluation for adults should begin with the patient completing part A of the Adult ADHD Self-Report Scale (ASRS-V1.1) to screen for symptoms, followed by a comprehensive clinical interview and assessment by a psychiatrist, psychologist, or specialized mental health professional. The evaluation process should include a review of medical, psychiatric, and educational history to rule out other conditions that might explain symptoms, as well as neuropsychological testing to assess executive functioning, attention, and memory 1.

Key components of the evaluation include:

  • A clinical interview to explore current symptoms, developmental history, family history, and how symptoms impact daily functioning across different settings
  • Standardized rating scales like the ASRS or Conners' Adult ADHD Rating Scales to measure symptom severity
  • Collateral information from family members or partners who have observed the person's behavior
  • Screening for co-occurring conditions like anxiety, depression, or substance use disorders, which frequently accompany ADHD

The evaluation should result in a clear diagnosis and treatment recommendations if ADHD is confirmed, taking into account the patient's overall health, potential comorbidities, and the potential benefits and risks of treatment, as outlined in recent guidelines 1.

It's essential to prioritize the most recent and highest quality study, which in this case is from 2024, to ensure that the evaluation and diagnosis are based on the latest evidence and best practices 1.

The entire evaluation process typically requires 2-3 sessions, allowing for a thorough assessment and diagnosis, and should be conducted by a qualified healthcare professional with experience in ADHD diagnosis and treatment.

From the Research

Full ADHD Evaluation in Adults

A full ADHD evaluation in adults is crucial for accurate diagnosis and effective management. The following points highlight the key aspects of a comprehensive evaluation:

  • A systematic diagnostic procedure should be followed, including a comprehensive clinical interview, rating scales for past and present symptoms, and collateral information from multiple informants 2, 3.
  • The evaluation should assess medical conditions associated with ADHD, such as sleep disorders, substance-use disorders, and other psychiatric disorders, to provide personalized care 2.
  • A range of structured interviews and standardized self-report questionnaires are available to evaluate core and associated ADHD symptoms, comorbidities, and functional impairment 2, 4.
  • The assessment should also include an evaluation of executive function and cognitive tests to understand the symptom patterns and develop targeted treatment programs 3, 4.

Diagnostic Challenges

Diagnosing ADHD in adults can be challenging due to:

  • The presence of comorbid psychiatric disorders, such as mood disorders, anxiety disorders, and personality disorders, which can mask or mimic ADHD symptoms 2, 3.
  • The internalization of hyperactivity and the masking of inattention symptoms by anxiety or obsessive-like compensation strategies 2.
  • The lack of objective, laboratory-based tests to establish the diagnosis, making clinical interviews and rating scales essential for diagnosis 3.

Treatment Options

Treatment for adult ADHD is multimodal and aims to relieve symptoms, limit the burden of the disease, and manage comorbidities. The following treatment options are available:

  • Medications, such as psychostimulants (e.g., methylphenidate) and nonstimulants (e.g., atomoxetine), which have been shown to be effective in treating ADHD symptoms 5, 6.
  • Psychological approaches, including psycho-education, cognitive-behavioral therapy, and "third wave therapies" with a focus on emotional regulation 2.
  • Combination pharmacotherapy, which may be necessary in certain situations, such as partial response, dose-limiting side effects, associated disorders, or comorbid diagnoses 6.
