Where AMA Title Case Is Used
AMA title capitalization is the standard for Medicine, Health Sciences, Biology, Nursing writing. When your work will be reviewed, published, or cited within these fields, using the correct capitalization shows attention to detail and compliance with professional standards. If your publication specifies a house style, follow that preference over the base standard.
How AMA Style Works in Practice
AMA title case is defined by the AMA Manual of Style, 11th edition, published by the American Medical Association. It is the standard for medical journals, health sciences research, biology, nursing, and allied health fields. AMA's defining feature is its all-capitals rule: every word in a title is capitalized, including articles, prepositions, and conjunctions. This means "A Study of the Effects of Sleep on Memory" becomes "A Study Of The Effects Of Sleep On Memory." While this rule is simpler to apply than the conditional rules of other styles, it makes titles look more heavily capitalized than any other major style.

Common Edge Cases in AMA Style
- There are essentially no exceptions to the all-capitals rule — every word, including "a," "an," "the," "of," "in," and "and," is capitalized.
- Hyphenated compounds: each part is capitalized (e.g., "Self-Report," "Evidence-Based").
- "To" in infinitives is capitalized: "How To Write A Manuscript" — unlike all other major styles.
- Proper nouns and abbreviations follow their own capitalization rules, unaffected by the all-caps rule.
- AMA style is used almost exclusively in the medical and health sciences — use APA or Chicago for other academic fields.
How AMA Differs From AP
AMA and AP both capitalize more words than Chicago or MLA, but they differ significantly. AP capitalizes words of 4 or more letters, leaving short articles and prepositions lowercase. AMA capitalizes every single word with no exceptions. In practice, AMA titles look more heavily capitalized than AP titles, particularly for words like "a," "an," "the," "of," "in," and "and," which AP lowercases but AMA capitalizes. AMA is appropriate for medical publishing; AP is the standard for journalism.
