What is Stroke? Symptom and management ,treatment, complication, physiotherapy

Introduction ;

               A stroke occurs when the blood supply to part of your brain is interrupted or reduced, preventing brain tissue from getting oxygen and nutrients. Brain cells begin to die in minutes.

A stroke is a medical emergency, and prompt treatment is crucial. Early action can reduce brain damage and other complications.The type of stroke you have affects your treatment and recovery.

The three main types of stroke are:

• Ischemic stroke.
• Hemorrhagic stroke.
• Transient ischemic attack (a warning or “mini-stroke”).

Learn about the health conditions and lifestyle habits that can increase your risk for stroke.

Ischemic Stroke

Most strokes (87%) are ischemic strokes.1 An ischemic stroke happens when blood flow through the artery that supplies oxygen-rich blood to the brain becomes blocked.

              
                               

Blood clots often cause the blockages that lead to ischemic strokes.

Hemorrhagic Stroke

A hemorrhagic stroke happens when an artery in the brain leaks blood or ruptures (breaks open). The leaked blood puts too much pressure on brain cells, which damages them.

High blood pressure and aneurysms—balloon-like bulges in an artery that can stretch and burst—are examples of conditions that can cause a hemorrhagic stroke.

There are two types of hemorrhagic strokes:

• Intracerebral hemorrhage is the most common type of hemorrhagic stroke. It occurs when an artery in the brain bursts, flooding the surrounding tissue with blood.
• Subarachnoid hemorrhage is a less common type of hemorrhagic stroke. It refers to bleeding in the area between the brain and the thin tissues that cover it

symptoms

• Sudden numbness or weakness in the face, arm, or leg, especially on one side of the body.
•                        
• Sudden confusion, trouble speaking, or difficulty understanding speech.
• Sudden trouble seeing in one or both eyes.
• Sudden trouble walking, dizziness, loss of balance, or lack of coordination
• .Treatment;
• An IV injection of recombinant tissue plasminogen activator (tPA) — also called alteplase (Activase) — is the gold standard treatment for ischemic stroke. An injection of tPA is usually given through a vein in the arm with the first three hours. Sometimes, tPA can be given up to 4.5 hours after stroke symptoms started
