Which type of stroke involves a ruptured blood vessel?

A hemorrhagic stroke occurs when a blood vessel in the brain ruptures, leading to bleeding within the brain or surrounding areas. This type of stroke can cause increased intracranial pressure and damage to brain tissue due to both the disruption of normal blood flow and the direct effects of the blood on the neural tissues. The burst vessel can be the result of various factors, including high blood pressure, arteriovenous malformations, or aneurysms.

In contrast, an ischemic stroke is caused by a blockage in a blood vessel, leading to insufficient blood flow to a part of the brain, which contrasts sharply with the concept of a rupture. Transient ischemic attacks, commonly referred to as transient strokes, are temporary blockages and do not involve permanent damage, while silent strokes typically do not present with noticeable symptoms but still result in brain injury due to infarcts, rather than a rupture of blood vessels.
