Clinical distinction of cerebral haemorrhage and cerebral infarction

Abstract

The clinical features of 62 cases of computerized axial tomography scan-proved cerebral haemorrhage and 81 cases of cerebral infarction in the carotid territory have been compared in a retrospective case note survey. The clinical features which can help in making the distinction between haemorrhage and infarction at the bedside are discussed and compared with those of classical teaching which referred only to post-mortem proved cases.

Siriraj stroke score and validation study to distinguish supratentorial intracerebral haemorrhage from infarction.

“…In For the validation study it was evident (fig 4) that the accuracy of the diagnosis would be optimised when the cut off points were set at -1 and 1. The Siriraj stroke score was thus set at that level to differentiate between haemorrhage and infarction.…”

Differential Diagnosis of Acute Stroke: A Review

“…Studies of patients with acute stroke in whom the diagnosis was made in life have largely confirmed the old observations that there are clinical features which are more common in one type of stroke than another (Harrison 1980, Allen 1983 (von Arbin et al 1981, Allen 1983). However, since about 80% of all patients have infarctions, the overall predictive accuracy of clinical diagnosis can be as high as 90%.…”

“…It has been reported that 59-80% of patients with haemorrhage have blood or xanthochromia in their CSF (Krabbe & Jorgenson 1931, Aring & Merritt 1935, Weisberg 1979, Harrison 1980, Britton et al 1983. Therefore the CSF examination as a test for haemorrhage may be specific (about 95%, Britton et al 1983) but has a false-negative rate of 20-40%.…”

Mri Study of Cerebrovascular Stroke

“…This is slightly higher than the study by Harrison et al, where maximum cases were between 50-59 years (33.33%). 11 In a review of stroke epidemiology by Feigin; they concluded that the average age of patients affected by stroke is 70 years in men and 75 years in women. Our statistics show a similar age reflection.…”
