A New Chapter: Election of the ECRA Board
Before the scientific sessions began, a pivotal moment for our community took place on Thursday. The European CMT Research Association (ECRA) held its General Assembly to elect the leadership team that will steer the scientific agenda for the coming years.
A new Board was voted in, comprising a President, Vice-President, Treasurer, Secretary, and five dedicated board members. This new leadership team is tasked with executing the 5-year ECRA Action Program, ensuring that patient priorities remain at the heart of European research funding and strategy.
