Preliminary Goals & Objectives
Scientific Abstract Presentations

Review of current clinical and basic science research pertaining to neuropathology with a focus on Canadian centres, but overall international participation. Also a platform for Canadian residents and trainees to present their recent work.

Diagnostic Case Presentations

Interactive discussion of rare and challenging neuropathological cases encountered by participants in their recent practice. Electronic slides and imaging results are distributed prior to meeting. Often includes case presentation by residents and illustrates advances in disease classification and diagnostic technique.

Overall learning objectives for the meeting

At the end of the meeting participants will:

  1. Describe recent developments in several areas of neuropathology with particular emphasis on the neuropathology of epilepsy and neoplasms.
  2. Discuss original research and challenging diagnostic cases with colleagues.
  3. Compare the practice of neuropathology on an individual and departmental level across Canadian centres.


Please note, all times are in CDT.
