                     BRAIN STROKE
Causes, Symptoms, and Prevention
A guide to recognizing, treating, and preventing one of the leading causes of disability worldwide.
What is a Brain Stroke?
● Occurs when blood supply to part of the brain is interrupted or reduced, 
depriving tissue of oxygen and nutrients
● Brain cells begin to die within minutes — making it a medical emergency
● Also called a “brain attack,” similar in urgency to a heart attack
~2 million
neurons lost every minute a stroke goes untreated

Types of Stroke
Ischemic Stroke
Caused by a blocked or narrowed artery, cutting off blood flow — usually from a 
0%
clot
87%
Hemorrhagic Stroke
are ischemic strokes
Caused by a blood vessel rupturing and bleeding into or around the brain
1%
TIA (Mini-Stroke)
Temporary symptoms that often warn of a future major stroke

Risk Factors
High Blood Pressure Diabetes & Cholesterol
The single biggest risk factor Damages blood vessels over time
Smoking & Alcohol Obesity & Inactivity
Heavy or regular use raises risk Linked to blood pressure & heart disease
Heart Disease Age & Family History
Especially atrial fibrillation Risk increases sharply after 55
Stress & Poor Sleep
Contributes to high blood pressure

Recognizing the Signs
Act F.A.S.T. — every second matters
F A S T
Face Arms Speech Time
Drooping on one side One arm drifts down Slurred or strange Call emergency now
Other warning signs: sudden confusion • vision problems • severe headache • loss of balance
Brain Stroke: Causes, Symptoms & Prevention 5
Why Speed Matters
“Time is brain” — every minute of delay costs neurons and function
0 24 hrs
Symptoms Mechanical clot
begin removal window
3–4.5 hrs Beyond
tPA clot-busting Higher risk of
window lasting damage
~2 million neurons are lost every minute a stroke goes untreated

Global & Regional Impact
Leading cause of death & disability
Stroke remains one of the top causes of death and long-term disability worldwide
Largely preventable
A large share of strokes are preventable through lifestyle and risk-factor management
Rising among younger adults
Incidence is increasing in younger populations, linked to lifestyle changes
Brain Stroke: Causes, Symptoms & Prevention 7
Diagnosis
CT / MRI Scan Blood Tests & ECG Carotid Ultrasound Angiography
Identifies stroke type and exact Checks clotting factors, sugar Examines blood flow through neck Detailed imaging of blood vessels 
location in the brain levels, and heart rhythm arteries for precise diagnosis
Brain Stroke: Causes, Symptoms & Prevention 8
Treatment Approaches
Ischemic Stroke Hemorrhagic Stroke Post-Stroke Care
Clot-dissolving medication (tPA) and Surgery to relieve pressure or repair Physical, speech, and occupational 
mechanical thrombectomy to restore vessels, plus blood pressure control therapy to support recovery
blood flow
Brain Stroke: Causes, Symptoms & Prevention 9
Prevention
Manage Vitals Quit Smoking & Limit Alcohol
Control blood pressure, blood sugar, and cholesterol Both significantly raise stroke risk
Stay Active & Eat Well Routine Checkups
Regular exercise and a balanced, low-salt diet Especially important for those with heart conditions

Recovery & Rehabilitation
● Recovery varies widely — some regain full function, others face lasting 
effects
● Rehabilitation focuses on relearning skills, mobility, and speech
● Emotional and family support plays a major role in recovery
Mobility Speech Support

Key Takeaways
It's an Emergency Mostly Preventable Know F.A.S.T.
Every minute counts — act Manageable through lifestyle and Recognizing the signs can save a life
immediately medical care
