Epilepsy encompasses medical, psychological, social and demographic fa
ctors which are best studied in large populations. The Canadian Epilep
sy Database and Registry (CEDAR) is a comprehensive English language,
multicentre epilepsy database which has been developed to study the im
pact of these and other factors on epilepsy in Canada. In addition, it
can be used locally in the clinic for office record keeping, automate
d printout of a referral letter or graphing seizures and other data ov
er time. The data in CEDAR are similar to what is found in the patient
's chart. There are 20 participating centres across Canada which have
entered data on over 8000 adult and pediatric epilepsy patients. The i
nformation in CEDAR will be available for research purposes to centres
entering data as well as to academic researchers, the pharmaceutical
industry and government agencies.
