Assoc. Prof. Ali Zirh is a world renowned neurosurgeon from Turkey. He was born on October 8, 1960 in Ankara, Türkiye and completed his primary and secondary education in the same city. He graduated from Ankara Atatürk High School with first place, and he entered the Hacettepe University Faculty of Medicine. He graduated from Hacettepe University Faculty of Medicine on August 31st, 1983 as a medical doctor. Between the years 1983 and 1985, he carried out his state service obligation in Gaziantep and was rewarded with a commendation by the Provincial Authority for his work in this period. He completed his military service in Istanbul in 1987 and was discharged.

In 1988, he started his specialization at Marmara University Faculty of Medicine, Department of Neurosurgery. In 1990, he attended the British Council in Glasgow and Edinburgh; the European Neurosurgery Association (EANS) in Warnemünde, Germany in 1989; Zaragoza, Spain in 1991; Jerusalem, Israel in 1992; Brudge, Belgium in 1993; and in 1994, he attended the World Neurosurgery Association (WFNS) training courses in Antalya, Turkey.

He became a neurosurgeon in February 1994. He completed his master's degree in neurophysiology at Marmara University Health Sciences Institute in March 1994. In September 1994, he completed the fifth of the European Neurosurgery Association's (EANS) training courses in Izmir, took the exams, and received his EANS diploma. On the same date, he participated in the European Board of Neurosurgery Primary Examination, passed successfully and certified.

In line with his field of interest, Stereotactic and Functional Neurosurgery, he attended training courses on "Stereotactic Target Calculation" and "Neurostimulation for Pain" in Çeşme İzmir in September 1994. "Stereotactic Neurosurgery Hands-On" in New-Orleans USA in November 1994, "Augmentitative Procedures for Pain" in San Francisco USA in October 1995, "Stereotactic Neurosurgery Hands" in New Orleans-USA in November 1995 , "Deep Brain Stimulation for Treating Parkinson's Disease" in Minneapolis-USA in May 1996, "Interventional Therapies Workshop: Implantable Spinal Cord Stimulation and Drug Infusion Systems" in Washington-USA in May 1996, "Surgical Treatment for Movement Disorders" and" Interventional Therapies in Chronic Pain Management" in Montreal-Canada in October 1996, "Management of Patients with Deep-Brain Stimulators, Expert Course and Workshop"  in Kiel-Germany in June 2001.

Dr. Ali ZIRH returned from the United States in 1997 and started to work at the VKV American Hospital, performing functional neurosurgery interventions and DBS insertion with the Microelectrode Recording and Stimulation technique at the single cell level, which is available in only a few centers in the world.

He started to work at Medicalpark Bahçelievler Hospital as of January 2009 and implemented these initiatives in a health institution where Social Security Institution patients could also benefit. He continues his surgical interventions at Medipol Bağcılar Hospital as of January 2015.

As of September 2018, he continues his academic and clinical studies at Medipol University's Parkinson's Disease and Movement Disorder Center (PARMER).

Over 30 years of clinical and surgical experience in the field of functional neurosurgery, more than 1900 surgical interventions for Parkinson’s and other movement disorder diseases and more than 1400 DBS surgeries that he has successfully performed, made Dr. Ali ZIRH the first name that comes to mind in movement disorder surgery in Turkey and the adjacent geography. He enabled the center where he performs these surgeries to become a Training and Reference Center in the international arena.
