Educational Workshop: How to Interpret the Neuropathology Sign-Out Report

Alzheimer’s Disease Pathology Under the Microscope and How to Report It (for Clinicians and Scientists)

Friday, July 12, 2019
8 a.m. – 5 p.m.
Intercontinental Los Angeles Downtown Hotel, Roosevelt


This workshop is intended to provide the participant with an understanding of the basic neuropathological features of age-associated neurodegenerative diseases. This will include neuropathological hallmark lesions that are seen in Alzheimer’s disease, primary tauopathies, α- synucleinopathies, diseases displaying inclusions with transactive DNA binding protein and various vascular lesions. Common consensus criteria applied during case assessment will also be discussed.

The workshop will consist of both interactive lectures and practical sessions. Numerous scanned histological slides will be assessed to provide information on how the observed lesions are interpreted (i.e. identify certain lesion, assess its extent and state its clinical relevance). A number of cases will be presented and discussed, including their clinical phenotype, the neuropathological observations, classification applied and the interpretation leading to a final diagnosis. The participant should gain a solid and lasting knowledge of the basics covered (i.e. various neuropathological lesions listed in a sign-out report and the classifications applied).

The organizers believe that the basic principles of neuropathology in neurodegeneration need to be understood by non-neuropathologists physicians and scientists. This understanding is vital in the interpretation of neuropathological data while reading sign-out reports and in the planning and conducting of scientific studies.
