The classic clinical presentation includes the onset of a sudden focal neurological deficit while the patient is active,which progresses over minutes to hours. This smooth symptomatic progression of a focal deficit over a few hours is uncommon in ischemic stroke and rare in subarachnoid hemorrhage. Headache is more common with ICH than with ischemic stroke, although less common than in subarachnoid hemorrhage. Vomiting is more common with ICH than with either ischemic stroke or subarachnoid hemorrhage. Increased blood pressure and impaired level of consciousness are common. However, clinical presentation alone, although helpful, is insufficient to reliably differentiate ICH from other stroke subtypes. The early risk of neurological deterioration and cardiopulmonary instability in ICH is high. Identification of prognostic indicators during the first several hours is very important for planning the level of care in patients with ICH. The volume of ICH and grade on the Glasgow Coma Scale (GCS) on admission are the most powerful predictors of death by 30 days. Hydrocephalus was an independent indicator of 30-day death in another study. Conversely, cortical location,mild neurological dysfunction, and low fibrinogen levels have been associated with good outcomes in medium to large ICH. Because of the difficulty in differentiating ICH from ischemic stroke by clinical measures, emergency medicine personnel triage and transport patients with ICH and ischemic stroke to hospitals similarly. As described below, patients with ICH often have greater neurological instability and risk of very early neurological d
