From 3 to 7 July, Barcelona hosted the 6th World Parkinson's Congress. This is the first time this congress has been held in Spain and was visited by more than 5,000 people from all over the world. The attendees were people with some kind of relationship with the disease: scientists, neurologists, nurses, specialists in movement disorders, physiotherapists and occupational therapists, phoniatricians, speech therapists and social workers, along with people with Parkinson's, their families and caregivers.

During the event, conferences and talks were given on advances in research and clinical practice, such as updates on the status of cures and new models of health care for Parkinson's patients. On the part of Vall d'Hebron, apart from presenting more than a dozen posters, the most outstanding interventions were given by researchers from the Neurodegenerative Diseases research group:

• The role of syncline and Lewy bodies, by Dr. Miquel Vila, head of the research group and co-chair of the local organising committee of the Congress. He also participated in a round table
• The science behind sex differences, by Dr. Ariadna Laguna, principal investigator and scientific ambassador of the Congress.
• Clinical fluctuations and dyskinesias, by Dr. Oriol de Fàbregas, neurologist in charge of the Movement Disorders Unit of the Neurology Service of the Vall d'Hebron University Hospital and principal investigator.
