Can acute stress be fatal? A systematic cross-disciplinary review.

This article compares different conditions in humans and in other animals, where it appears as if the human or animal dies with no other reason than being submitted to an extreme condition of mental stress. The conditions examined via a literature search are excited delirium syndrome, malignant catatonia and takotsubo cardiomyopathy in humans, and a capture myopathy in different mammals. The article theoretically suggests that one can die solely from acute stress, but that different forms sensitization probably goes ahead of such a fatal stress reaction. E.g. in cocaine addicts, some psychiatric patients, and in wild animals formerly subjected to stress an extreme sympathetic stress response might be immediately fatal. The article also theorizes that excited delirium syndrome, malignant catatonia, and capture myopathy could be more severe and acute variants of the temporary condition seen in takotsubo patients, also known as patients with broken heart syndrome.
