Bernt Harald Helleberg‘s PhD thesis is based on the Trondheim Early Neurological Deterioration Study, and indicates that even transitory neurological deteroriation following ischemic stroke impacts outcome negatively.

(1) The Trondheim Early Neurological Deterioration Study includes 368 patients with acute ischemic stroke. The study has several aims, including assessment of the relation between early neurological deterioration and functional level at three months post stroke. Other aims are to identify factors and mechanisms associated with such deteriotation, and to compare the different definitions of early neurological deterioration in the Scandinavian Stroke Scale and the National Institutes of Health Stroke Scale.
(2) So far, only the outcome study has been published in addition to the study protocol. The results show 34 times higher risk of death or dependency three months after stroke in the 14 % patients who suffered from early neurological deterioration. Furthermore, in the 28 % who experienced transitory episodes of deterioration, the risk was doubled compared to stable patients. The neurological function of each patient was assessed 12 times during the first 72 hours.
