General Conditions

The World Federation of ADHD and the Verein zur Durchführung Neurowissenschaftlicher Tagungen e. V. have commissioned CPO HANSER SERVICE with the organization and execution of the conference. Registration for the conference and confirmation therefore forms a contract between the conference attendee and the World Federation of ADHD and the Verein zur Durchführung Neurowissenschaftlicher Tagungen e. V. regarding attendance at the conference.

The contract is based on the following General Conditions:

Registration fees and payment for the 9th World Congress on ADHD

A separate registration fee will be charged for these events in addition to the conference fee. Registration for the conference and booking of services are binding for the attendee. The fees must be paid in advance on the dates specified. Any bank charges will be charged to the payer. Registration will be confirmed if payment is received.

Submission of a poster simultaneously results in binding registration of the speaker to attend the conference. The registration fee must be paid together with the submission of the contribution otherwise the poster will not be reviewed. Cancellation of conference attendance is possible at no additional cost if the poster is rejected by the scientific committee. In this case, the full registration fee will be refunded.

If the author withdraws a contribution after its acceptance by the scientific committee, registration for the conference will be maintained and there will be no refund of the registration fees.

Cancellation of Congress Attendance

In the event that you cancel your attendance at the congress and the educational seminars until 7 March 2023, the registration fee minus a processing fee of EUR 100 will be refunded.
