Study Notes
Stroke Definition
- Stroke is a sudden onset of localized neurological problems.
- These problems last for at least 24 hours.
Types of Stroke
- Stroke can be ischemic or hemorrhagic.
Transient Ischemic Attacks (TIAs)
- TIAs are temporary, localized interruptions in brain function caused by impaired blood flow.
- TIAs involve ischemic (reduced blood flow) brain regions.
- TIAs resolve quickly, typically in less than 24 hours.
