AEIOUTIPS is used to recall what clinical concept?

• A. Causes of altered LOC
• B. Neurological imaging findings
• C. Types of coma
• D. Levels of consciousness assessment

Answer: (A)

AEIOUTIPS is a mnemonic to remember the major categories that can cause an altered level of consciousness. When a patient presents with confusion or reduced responsiveness, this framework helps you quickly consider a broad differential instead of missing key reversible causes. Each letter points to a group you should evaluate: Alcohol (intoxication or withdrawal), Epilepsy or metabolic/endocrine disturbances, Insulin-related hypoglycemia, Opiates, Uremia, Trauma, Infection, Poisoning, and Stroke. This organization guides immediate steps—check glucose to rule out hypoglycemia, assess for toxin exposure, look for signs of infection or stroke, and evaluate for metabolic or renal causes—while avoiding missing common, treatable etiologies.
