Populærvitenskapelig sammendrag av avhandlingen/ Summary of the thesis:

Wake-up stroke is a stroke that occurs during sleep and is discovered when the patient wakes up. Because stroke treatment is highly time-dependent, treatment decisions in wake-up stroke are challenging since the exact time of symptom onset is unknown.
In this thesis, we used data from the Norwegian Stroke Registry to study how often wake-up stroke occurs, the effects of treatment and survival rates after stroke.
We found that about one in five strokes are wake-up strokes. In many respects, these strokes resemble strokes with a known time of onset. Long-term survival was similar in patients with wake-up stroke and those with known onset, but poorer in patients with strokes of unknown onset for other reasons than sleep. We also examined the effectiveness and safety of clot-dissolving treatment (intravenous thrombolysis). The treatment was associated with better functional outcomes and appeared to be safe in patients with wake-up stroke in our real-world population.
