Summary
Every page on HeadInjury.com is built from published, credible sources. We cite nearly every factual statement, attribute guidance to the organization that issued it, avoid diagnosing readers, and record when each page’s sources were last checked.
Sources we use
We rely on sources in roughly this order of preference:
- U.S. government health agencies, such as the Centers for Disease Control and Prevention (CDC), the National Institute of Neurological Disorders and Stroke (NINDS) and MedlinePlus from the National Library of Medicine
- Clinical consensus statements and guidelines from recognized professional bodies
- Peer-reviewed research and systematic reviews, generally accessed through PubMed or PubMed Central
- Peer-reviewed clinical references, such as StatPearls on the NCBI Bookshelf
- Statutes, regulations and official government sites for legal and policy topics
We do not use sources that sell treatments, devices or legal services as support for medical facts.
How we cite
- Factual statements carry a numbered reference that links to the full citation at the bottom of the page.
- Each citation includes the publisher, title and a direct link to the source.
- Statistics are reported with the population, time period and source they come from, because figures differ between studies.
- Where sources disagree or definitions vary, we say so rather than picking a single number.
How we write
- We describe what sources say, and attribute guidance to the organization that issued it.
- We do not tell readers whether they have a condition or what care they personally need.
- We use plain language and explain medical terms when they first appear.
- Differences by age group are covered within each condition page.
Updates and corrections
Each page shows the date its sources were last checked. We revisit pages when major guidance changes, such as a new consensus statement or updated agency data. If we find an error, we correct it and update the page date.
Legal information
Legal pages follow the same standard as our medical pages: every factual statement is cited, and the law is quoted rather than paraphrased wherever practical.
- Statutes and regulations are quoted from official code sites (such as state legislature websites, ssa.gov and the U.S. Code) or from the Legal Information Institute at Cornell Law School, and linked at the point they are quoted.
- Agency guidance comes from the agency that administers the program, such as the Social Security Administration, the Department of Veterans Affairs, the Department of Labor, the Office for Victims of Crime and HHS.
- Court rules and cases are cited to the rule text or the published opinion. When a page describes how courts have treated an issue, it names the court.
- Insurance information comes from state insurance regulators, statutes and the Insurance Information Institute.
- Dollar amounts and limits, such as Social Security payment amounts, are given with the year they apply to.
Laws change. We recheck legal pages after each state legislative session and when benefit amounts are adjusted each year, and every page shows the date its sources were last checked. Legal information on this site is general and is not legal advice. See our legal disclaimer.
