MeSH (Medical Subject Headings) is a medical thesaurus used by PubMed and Medline to index records. Medical Subject Headings (called descriptors) follow a controlled and standardised vocabulary. Terminology is standardised so all articles on a particular topic are assigned a consistent subject heading. For example, articles about high blood pressure will be indexed under the MeSH descriptor, Hypertension. Most articles have more than one subject heading, e.g.:
Type a topic into the box and click ‘Find MeSH terms’. For example,
mild traumatic brain injury
Select Brain Concussion from the results.
This is the MeSH descriptor record for Brain Concussion. The Scope Note provides a succinct definition of the heading. The Entry Term(s) provide some alternative (synonymous) keywords. These are not MeSH terms, but you can use them in your search as alternative search words.
General note: MeSH uses American spelling, e.g. gynecology, not gynaecology; behavior, not behaviour.
