He is certified in Neurosonology by the Amercian Society of Neuroimaging.

RESEARCH INTERESTS

Dr Ramani's present research interests include clinical trial of medications in acute stroke, neuroepidemiology and neurosonology. He is the hospital Principal Investigator of a number of Phase II and II international trials, as well as an NMRC-funded community survey on the prevalence of neurological diseases in Singapore.

CURRENT RESEARCH PROJECTS

• Community survey on the prevalance of neurological diseases in Singapore
  
  This study will include 15000 Singaporeans above 50 years old residing in central Singapore. They will be screened for neurological diseases using a questionnaire, followed by a clinical examination. the target diseases are dementia, epilepsy, parkinsonism and stroke. The study is scheduled to run from early 2001 to end 2002.
