title: [Neurological complications of infective endocarditis].
abstract: Infective endocarditis involves the brain in 20-40% of cases. The neurologic syndrome often is the presenting feature. The most frequent neurologic complication is cerebral ischemia. In these patients and those with intracranial hemorrhage, a heart murmur as well as systemic signs of inflammation point to endocarditis. The encephalopathy in endocarditis is mostly due to cerebral infarction. In bacterial meningitis and brain abscess an uncommon isolate arouses suspicion. The most important therapy is antibiotic treatment. Valve replacement improves outcome; in the acute phase of endocarditis, however, it is only necessary in a third of the patients. Neurologic complications interfere with the timing of the valve replacement. If it is urgently required, its risk is reasonable within 3 days after cerebral ischemia; if possible 2-4 weeks should be waited. Cases of successful valve replacement within 4 weeks after intracranial hemorrhage have been reported, but it is recommended to postpone it for 4-6 weeks. There are no data available for the other neurologic complications. Even today patients with endocarditis challenge the diagnostic and therapeutic capacity of various disciplines.
