ADHD testing is a structured assessment that looks at attention, focus, history and daily function to determine whether ADHD is present, and what else may be contributing. At Sphosh Health, Dr. Koichi Tanji, ND, LMHC provides comprehensive ADHD testing for adults and children that goes beyond a checklist, weighing sleep, nutrition, stress and medical factors so the diagnosis and plan reflect the whole person.


We take a full history, use validated ADHD assessment tools, and consider the sleep, nutrition and medical factors that can mimic or worsen symptoms, then explain the results in plain language and outline next steps, whether that is treatment, support or further evaluation.
Good ADHD testing is not a five-minute questionnaire. Here is how the process usually unfolds at Sphosh Health, whether you come in to our Bellevue office or meet Dr. Tanji by secure video from anywhere in Washington.
Our clinic is at 2135 112th Ave NE, Suite 201 in Bellevue, minutes from downtown Bellevue and the Spring District, just off I-405, and a short drive from Kirkland, Redmond, Issaquah and Sammamish. Many patients choose telehealth instead, completing the whole evaluation from home anywhere in Washington, a real advantage when focus and scheduling are already the challenge.
