Mark every instance of a Disease, Disease Class, Symptom or Sign/Diagnostic Sign
Eg- Ataxia is a type of movement disorder
Use the minimum span needed to encompass multiple terms of a disease, disease class, symptom, or sign/diagnostic sign. If there are multiple, nested terms, mark the minimum span that is needed in order to be able to distinguish your markings as a disease, disease class, symptom, or sign/diagnostic sign without the surrounding text.
Eg- Mark: incessant jiggling or twitching of the toes, NOT just jiggling or twitching
Mark each instance of a disease, disease class, symptom, or sign/diagnostic sign separately or in a separate span (if an instance has multiple words).
Eg- Mark: present with heart disease, high blood pressure, and high LDL levels
Not: present with heart disease, high blood pressure, and high LDL levels
Mark each instance of an abbreviation of a disease, disease class, symptom, or sign/diagnostic sign
Mark specific forms of a disease, disease class, symptom, or sign/diagnostic sign preferentially over more general forms of the disease
Eg- Familial Alzheimer Disease instead of Alzheimer Disease
Eg- Early-Onset Alzheimer Disease instead of Alzheimer Disease
