The Unit’s research strategy is clinical and patient-centred, with the primary objective being to further improve the outcome and the quality of life of patients, and to develop new therapies for functional brain disorders. Additionally, translational research projects with external collaborators are aimed at testing new strategies to treat Parkinson’s disease and other functional brain disorders. The approach is multidisciplinary, multicentre, national and multinational. Disciplines involved include neurology, neurosurgery, neuroradiology, physics, neuropsychology, neurophysiology, neuropsychiatry, neurogenetics, neurorehabilitation, and neuro-engineering.
The principal research aims are:
Evaluate novel surgical and non-surgical therapies that do not involve electrical brain stimulation.
Expand DBS to the treatment of other disorders of the brain, in particular through national and international multicentre studies.
Improve the visualisation on imaging and targeting accuracy of existing brain targets by use of high field MRI.
Better understand how DBS works and what it affects, through the use of diffusion MRU, functional MRI, recording of local field potentials,
Magnetoencephalography (MEG) and Transcranial Magnetic Stimulation (TMS).
Improve the delivery of DBS in patients with Parkinson´s disease by investigating closed loop stimulation based on physiological feedback from brain targets, and by evaluating new models of electrodes delivering directional electric current.
Document the impact of DBS and understand the mechanisms of its effects on cognition, mood and behaviour.
Develop and validate alternative methods for management of mobility and cognitive problems in PD.
Perform in-depth evaluation of the effects of DBS on quality of life.
Exploration and studies of gender-related aspects in patients with movement disorders.
Explore novel applications of DBS and stereotactic lesional surgery in psychiatry, in particular in depression, obsessive compulsive disorders and anorexia.
Explore MRI-based biofeedback training of patients with Parkinson´s disease
