ADHDcentraal is an expertise agency in the area of ADHD and ADD. ADHDcentraal provides careful, ‘state of the art’ specialist diagnostics and treatment for adults (18 years and older). The diagnostics at ADHDcentraal contain very advanced tests and components that make it possible to tailor the treatment to the individual. For this reason, we can only treat people who have completed the diagnosis day with us. ADHD is often accompanied by other psychological problems such as mood problems, anxiety problems, substance abuse, sleep problems, negative self-image, fear of failure and personality problems. Our treatment is geared to the treatment of ADHD and ADD as the primary diagnosis. We also treat other psychological problems unless they are so serious that they are of primary importance, require specialist assistance, require 24-hour care or require a clinic.
