Brain & Neuroplasticity

Functional Neurology Made Easy and Understandable

A few years ago we launched a series of accredited modules with the intention to introduce fellow chiropractors to the world of functional neurology. Each model we put together consists of a day session during which we discuss (in a simplified manner) the main centres of the nervous system and show the practical therapeutic applications of a functional neurologic approach. Courses take place mainly in Leiden (Netherlands) and are held in English.

We believe functional neurology has made us better chiropractors and are very excited to share our knowledge whether you are a seasoned chiropractor looking for a functional neurologic approach, or a new graduate looking for a stepping stone towards a full degree in functional neurology.
Our lecturers are chiropractors trained by the Carrick Institute and are Diplomates of the American Board of Functional Neurology (DACNB). Furthermore, they all have ample experience as chiropractors, teachers, lecturers and leaders.

All modules can be taken independently and each one of them has been granted European Academic Council (EAC) accreditation equal to 8 CPDs per module. You are welcome to step in at any time.

Each module has an important practical component, to ensure you can start applying new knowledge the very next day. Therefore we keep our groups small and guarantee a personalised approach. So, don’t wait another minute and sign up today!
