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 clinical Neurology and Neurosurgery services and research resources with the Department of Clinical Neurosciences at Singapore General Hospital. 

NNI Today

Today, NNI operates out of 7 hospitals in Singapore – Changi General Hospital (CGH), KK Women’s and Children’s Hospital (KKH), Khoo Teck Puat Hospital (KTPH), Sengkang General Hospital (SKH), Singapore General Hospital (SGH), TTSH and Woodlands Health (WH).  We are a member of the Singapore Health Services (SingHealth) – a public healthcare cluster which manages four hospitals, five specialty centres, eight polyclinics and a network of community hospitals – and the SingHealth Duke-NUS Academic Medical Centre.
