The previous decline of the incidence of stroke is now less apparent. Most of this decline was in ischaemic stroke; the changes in haemorrhagic stroke are less certain. We have documented on our stroke data bank in Toronto the stroke frequency. We collected retrospective data of 182 admissions for cerebral haemorrhage. 126 (69%) were direct admissions to emergency and 56 (31%) were referral. In hospital mortaility rate was higher in the emergency group than in the referral group (52% vs 19.6%). Moreover, patients from the referral group were found to have predominant lobar haemorrhage and less proportion of central lesion. In 1976, 10.1% of strokes admitted rate in the week was 47%. In 1997, 10% of strokes were haemorrhagic but the mortality rate was 37% ( P > 0.05). Although some of these differences probably represent referral bias, these data indicate a decline in mortality but not incidence.
