Hemorrhagic stroke is a broad category of stroke and includes intracerebral hemorrhage and subarachnoid hemorrhage. Together these two conditions represent 13-20% of stroke cases with the rest being due to ischemic stroke. Intracerebral hemorrhage is more common than subarachnoid hemorrhage with the later representing approximately 5% of all strokes.
Intracerebral hemorrhage presents with sudden onset focal neurological deficit. This may be accompanied by a headache and nausea. The main differential diagnosis is ischemic stroke. Subarachnoid hemorrhage presents with sudden severe headache. In more severe cases patients with either condition may present in coma.
The conditions are separate with different etiology and management strategies. Please see dedicated sections; intracerebral hemorrhage or subarachnoid hemorrhage.
