What mnemonic is used to remember red flags for secondary headache disorders?

• A. SNOOP4
• B. VINDICATE
• C. OPQRST
• D. PQRST

Answer: (A)

Screening for secondary headaches relies on recognizing red flags that suggest a potentially dangerous intracranial process. The SNOOP4 mnemonic helps you quickly recall the major warning signs: Systemic symptoms (fever, weight loss) can point to infection or systemic illness; Neurological signs or symptoms (focal deficits, confusion, weakness) raise concern for intracranial pathology; Onset is abrupt or thunderclap, which is typical of conditions like subarachnoid hemorrhage; Older age (usually over 50) increases the likelihood of vascular or neoplastic causes; Pattern change or new headaches in someone with a prior migraine, or headaches precipitated by exertion/Valsalva, signal a possible secondary process such as a mass or raised intracranial pressure. Together these features guide urgent evaluation and imaging when present. Other mnemonics don’t fit this specific purpose. VINDICATE is a broad differential-diagnosis framework, not a focused red-flag checklist for headaches. OPQRST and PQRST are tools for describing and evaluating pain characteristics and timing, not for identifying safety flags that require immediate investigation in headache disorders.
