A history of hypertension, trauma, illicit drug abuse, or a bleeding diathesis may be elicited.
Acute onset, with rapid clinical deterioration (within minutes-hours)
Alteration in level of consciousness (approximately 50%)
Nausea and vomiting (approximately 40-50%): but rarely at the onset
Headache (approximately 40%)
Seizures (approximately 6-7%)
Anisocoria
Focal neurological deficits
