What are some causes of cerebrovascular accidents?

Cerebrovascular accidents, commonly known as strokes, occur when there is a sudden disruption of blood flow to the brain, which can lead to brain damage and functional impairment. Transient Ischemic Attacks (TIAs) and cerebral thrombosis play significant roles in the causation of these events.

TIAs are often referred to as "mini-strokes" and result from temporary disruptions in blood flow, serving as critical warning signs indicating that a more severe stroke may occur in the future. Cerebral thrombosis involves the formation of a blood clot within the blood vessels supplying the brain, which can lead to an ischemic stroke if the flow is not restored. Both TIAs and thrombosis are commonly recognized as direct causes of cerebrovascular accidents, emphasizing their importance in the study of stroke pathology.

In contrast, other options such as infections or tumors, dehydration and fatigue, and spinal injuries or fractures do not directly cause cerebrovascular accidents. While infections and tumors can affect the overall health of an individual and could possibly lead to complications that might indirectly influence neurological outcomes, they are not classified under the main causes of strokes. Similarly, dehydration and fatigue, although they may impact overall health, are not established causes of cerebrovascular accidents. Spinal injuries and
