What makes it different?
No permanent damage — but a major warning sign for future stroke.
A stroke happens when blood flow to part of the brain is blocked or when a blood vessel in the brain bursts. Without oxygen, brain cells begin to die within minutes.
A stroke can occur in two main ways:
Blocked artery (ischemic stroke)
Burst or leaking blood vessel (hemorrhagic stroke)
A transient ischemic attack (TIA) happens when blood flow is briefly blocked.
The major stroke types include:
Ischemic stroke (most common)
Thrombotic stroke
Embolic stroke
Hemorrhagic stroke
Intracerebral hemorrhage
Subarachnoid hemorrhage
Transient ischemic attack (TIA)
Each type affects the brain differently.
A simple way to remember the signs is FAST:
Face drooping
Arm weakness
Speech difficulty
