What happens when the brain swells after a stroke?
Brain swelling, referred to as cerebral edema, is one of the immediate short-term dangers of stroke. Large strokes, in particular, may cause significant swelling that can rapidly worsen, leading to serious consequences including severe brain damage, a permanent state of unresponsiveness, or even death.
How long does it take for brain swelling to go down after a stroke?
The swelling is composed of a mix of fluid and inflammatory cells. Brain edema begins to develop during the first 24 to 48 hours and reaches its peak three to five days after the onset of a stroke. 2 Afterward, the edema decreases gradually over the following weeks.

What causes brain swelling after a stroke?
Brain swelling is an urgent clinical problem that frequently accompanies ischemic stroke, brain hemorrhage and traumatic brain injury, and it increases morbidity and mortality associated with them. It occurs due to failure of membrane transporters and the blood-brain barrier (BBB), resulting in combination of cytotoxic, ionic and vasogenic edema.
What causes a hemorrhagic stroke?
They’re caused by a weakened vessel that ruptures and bleeds into the surrounding brain. The blood accumulates and compresses the surrounding brain tissue. The two types of hemorrhagic strokes are intracerebral (within the brain) hemorrhage or subarachnoid hemorrhage. A hemorrhagic stroke occurs when a weakened blood vessel ruptures.
What is the difference between a stroke and hemorrhage?
As the brain responds, swelling occurs. Hemorrhagic strokes: Hemorrhage refers to blood leaking from a blood vessel in the brain (intracerebral). Hemorrhagic strokes are the most common type of stroke. They occur when blood vessels anywhere in the brain rupture. As blood leaks and the body responds, pressure builds inside the brain.
What are the symptoms of a hemorrhagic stroke?
