What type of stroke is characterized by bleeding in the brain?

The type of stroke characterized by bleeding in the brain is known as a hemorrhagic stroke. This occurs when a blood vessel in the brain ruptures, leading to bleeding either in the brain tissue itself or in the space surrounding the brain. This bleeding can cause increased pressure in the skull and damage brain cells, which is the hallmark of a hemorrhagic stroke.

In contrast, an ischemic stroke is caused by a blockage in a blood vessel that supplies blood to the brain, resulting in a lack of oxygen and nutrients. A transient ischemic attack (TIA) is often referred to as a mini-stroke and occurs when there is a temporary decrease in blood flow to the brain without permanent damage. Transitional stroke, while not a standard medical term, may reference the movement between different types of strokes but does not specifically pertain to brain bleeding.

Thus, hemorrhagic stroke stands out clearly due to its defining feature of bleeding, making this the correct choice.
