Padraig O'Suilleabhain, M.D.

Half way through his medical education in Dublin Ireland, Padraig O’Suilleabhain came to Mayo Clinic in Rochester Minnesota for an elective rotation in neurology. Hugely impressed with the training program, he returned 1992-1998 for neurology residency and for fellowships in movement disorders and clinical research. He then joined the faculty of UT Southwestern Medical Center, where in due course he was promoted to Professor. His duties encompass teaching, administration, patient care, and research. Some high points of each are noted here:

• Dr. O’Suilleabhain is a mentor within UT Southwestern’s colleges program. He is assigned a group of 6 incoming medical students most years, and meets with them frequently during the course of their 4 years of study, training them in clinical skills and professional ethical behaviors.
• Elected to Executive Committee of the Board of the UT Southwestern Medical Group - which is the faculty practice plan – he participates in strategic planning for the Group.
• Caring for patients remains the primary identity and passion of Dr. O’Suilleabhain. He has particular focus on treatment of Parkinson disease, Progressive Supranuclear Palsy, and dystonia. Most of his time is face to face with someone struggling with a brain disease, trying to help the person and the caregivers get the best treatment and outcomes currently available.
• There is need and opportunity for better treatments in the future. His primary research project currently involves sifting through the magnetoencephalographic signals generated during skilled activities such as writing, and how this is altered in dystonia and movement disorders. He also investigates new treatments for parkinsonism and other diseases of the basal ganglia.

Dr. O’Suilleabhain is a member of the American Academy of Neurology, the American Neurological Association, the International Parkinson and Movement Disorder Society among others.
