Explore asterixis, often called the 'liver flap,' a critical neurological sign indicating toxic-metabolic encephalopathy. Learn why this 'negative myoclonus' isn't a tremor, how to spot its distinctive 'flapping' motion, and its diverse etiologies, from liver and kidney disease to hypoglycemia and medications. We demystify its strong historical link to hepatic issues and emphasize why this finding is key to a complete diagnostic assessment.
