What is a 'brain attack' or a stroke?

• A. the process of any interruption of the normal blood supply to a part of the brain or the entire brain, resulting in damaged brain tissue.
• B. A temporary loss of consciousness due to low blood sugar
• C. A brain tumor
• D. A spinal stroke

Answer: (A)

A stroke, or brain attack, is when the brain’s blood supply is suddenly interrupted, and brain tissue begins to die from lack of oxygen and nutrients carried by the blood. This disruption can be due to a blocked artery (ischemic stroke) or bleeding into the brain (hemorrhagic stroke), but the common outcome is damage to brain tissue and sudden neurologic changes such as weakness, trouble speaking, or facial droop. The other options describe different problems: low blood sugar causing temporary loss of consciousness, a brain tumor, or a stroke affecting the spinal cord rather than the brain.
