Tranisnt Ishemia

Question 1

Initial event - transient blood flow obstruction

Answer 1

A brief interruption of blood supply -
Thromboembolism,
Atherosclerotic narrowing
Vasospasm
Hypoperfusion

Lack of oxygen & nutrients causes a temporary energy crisis in affected neurons

Question 2

Compensating mechanisms

Answer 2

Collateral circulation,
Neurochemical adaptation
Reperfusion

Question 3

Resolution

Answer 3

Within minutes or hours, normal blood flow normalises
Unlike a stroke, the transient nature stops permanent cell death

Question 4

What is it?

Answer 4

Transient ischemic attack (TIA), often referred to as a “mini-stroke,” is a temporary disruption of blood flow to part of the brain, spinal cord, or retina, typically lasting less than 24 hours and leaving no permanent damage. It is a warning sign of potential future strokes
