Cardial diseases are common causes of neurological emergencies.On the other hand, acute neurological disorders go along with systemicabnormalities, in particular they show cardial and pulmonary complications.This review is focused on the cardial consequences of cerebral lesions. Independenton the etiology of the brain disorder, the central activation ofthe adrenergic system plays a key role in the pathophysiology. The adrenergicstimulation modulates cardial function. ECG-changes, elevated cardialenzymes, arrhythmias, and sudden cardial death can be the consequences.In these cases, the adequate treatment of the neurological disorderis essential for the improvement of systemic symptoms. The cardialdisorders (apical ballooning cardiomyopathy, neurogenic pulmonaryedema) then have a favourable prognosis. For future studies on treatmentof neurogenic-cardial disorders, the classification of the differentlydefined disorders based on their common pathophysiology will beessential.
