The medical literature is inconsistent in the words and terms used to refer to the same concept. For example, one author may refer to a "cerebrovascular accident," while another may refer to the same condition as "acute stroke." For consistency, a controlled vocabulary is used when indexing each journal article. For more focused searching and more exact search results, you can use the Thesaurus to determine the valid IDIS controlled-vocabulary term for a drug, disease or condition.
