Comprehensive ADHD Testing for Adults: Get the Clarity and Support You Need

Attention-deficit/hyperactivity disorder (ADHD) is a common neurological condition that affects up to 4% of adults. Children with ADHD often have trouble focusing, may be very active, and can act impulsively, which can make everyday tasks challenging. These symptoms can impact work and friendships, so getting an accurate diagnosis and the right support can make a big difference.

Living with undiagnosed ADHD as an adult can feel isolating, especially when symptoms interfere with everyday tasks others seem to handle with ease. You might struggle with focus, lose track of deadlines, or feel overwhelmed by organizing and planning, all while wondering why these things seem so much harder for you. Conversations might drift as your attention slips, and simple routines—like paying bills or keeping up with commitments—can feel like constant battles. It can be frustrating and lonely, especially when you see others moving forward smoothly while you’re grappling with what feels like an invisible barrier. This isolation can deepen when those around you don’t understand or think you’re just being “forgetful” or “disorganized.” But you’re not alone; many adults with ADHD experience these same struggles, and with proper support, you can find practical ways to manage symptoms and reconnect with what matters most.  

Psychological testing is one of the most helpful ways to identify ADHD. This type of evaluation gives a full picture of someone’s attention, behavior, and emotional health. Testing usually includes interviews, checklists, observations, and sometimes special cognitive/intelligence and neuropsychological tests.  Neuropsychological tests are specialized tools designed to assess different cognitive abilities, such as attention, memory, executive functioning, and processing speed. These tests are especially useful in ADHD evaluations, as they can reveal the underlying brain processes that may contribute to ADHD symptoms.  Intelligence testing usually involves standardized assessments that measure different cognitive skills, including verbal comprehension, perceptual reasoning, working memory, and processing speed. These tests offer a detailed view of an individual’s cognitive strengths and weaknesses, helping to identify any specific challenges that might contribute to ADHD symptoms or affect daily functioning. 

At Calibrate, a typical ADHD evaluation consists of an initial diagnostic interview (telehealth, about 1-1.5 hours), in-person testing (2.5-3.5 hours at my Bellevue, WA location), and a feedback session to hear the results and discuss next steps (telehealth, about 1-1.5 hours).  This of course can vary depending on each individual.
