Our History

The National Neuroscience Institute (NNI) is the national centre for referrals in neurosciences. It was the last of the three national centres to be established as part of the government’s blueprint for enhanced specialist healthcare. 


As the national and international centre of excellence in the neurosciences; our mission and goals rest upon our tripod of strengths – patient care, research and education. 

The establishment of NNI in 1999 resulted in the transfers of the Departments of Neurology and Neurosurgery from Tan Tock Seng Hospital (TTSH) to form the foundations of clinical service.  NNI officially started operations on 1 June 1999. At that time, we occupied part of the new Tan Tock Seng building and functioned as the neuroscience division of TTSH. A new department of Neuroradiology was later initiated to provide the specialised diagnostic imaging and interventional services for neurological diseases. These were supported by dedicated bench research laboratories, as well as administrative and education resources.

In 2001, the NNI integrated the TTSH campus clinical Neurology and Neurosurgery services and research resources with the Department of Clinical Neurosciences at Singapore General Hospital. 

NNI Today

Today, NNI operates directly from both campuses, as well as provides specialty services to most other hospitals in Singapore.  We are a member of the SingHealth (Singapore Health Services) Group, an integrated healthcare delivery network which offers a complete range of multi-disciplinary and integrated medical care. The Group comprises hospitals, national specialty centres and a network of polyclinics.
