Council of Nations
The Council of Nations (CoN), established at the WON/ESNCH Conference in Lisbon in 2022, is a network dedicated to strengthening international collaboration and advancing Neurosonology worldwide.
Each national representative, appointed as a WON/ESNCH Ambassador, promotes Neurosonology in their country by supporting educational activities, scientific meetings, and new memberships in the Society.
Ambassadors are nominated by the CoN Coordinators among recognised experts in Neurosonology, with preference given to colleagues actively involved in scientific and educational activities within their national communities. The activity of each Ambassador is reviewed every two years for possible renewal.
Below you will find the list of countries currently represented - if your country is not yet included, you can contact us to propose a qualified Ambassador.

History
As Neurosonology became essential in neurovascular care, the European Society of Neurosonology and Cerebral Hemodynamics (ESNCH) was born.
Proposed by Professor David Russell in December 1993, the first official meeting of the society took place in Munich, Germany, in 1996. The first statutes of the ESNCH were later approved by general assembly during the second meeting, in 1997.
With its growing impact and worldwide recognition, ESNCH evolved into the World Organisation of Neurosonology (WON) in 2024, reflecting its global reach and continued commitment to advancing Neurosonology.
