Strokes: A Global Public Health Priority

The World Health Assembly has passed a Resolution on Strokes, recognising it as a public health priority. Read here to learn more.

The World Health Assembly (WHA) passed the first-ever resolution on strokes, urging member states to recognise the medical condition as a public health priority and to strengthen national policies across the full care pathway.

This involves prevention and risk‑factor control, timely acute treatment, expanded rehabilitation, and long‑term support.

What is a stroke?

A stroke is a medical emergency that occurs when the blood supply to a part of the brain is interrupted, preventing brain tissue from receiving oxygen and nutrients. Brain cells begin to die within minutes, making immediate treatment critical.

Stroke can result in:

• Paralysis
• Speech and memory problems
• Permanent disability
• Death

Types of Strokes

1. Ischemic Stroke (Most common)

• Occurs when a blood vessel supplying the brain becomes blocked by a clot.
• Accounts for approximately 85% of stroke cases.

Causes:

• Atherosclerosis (fat deposition in arteries)
• Blood clots
• Heart rhythm disorders such as atrial fibrillation

Example: A clot formed in the heart travels to the brain and blocks blood flow.

2. Hemorrhagic Stroke

• Occurs when a blood vessel in the brain bursts, causing bleeding into surrounding tissues.

Causes:

• High blood pressure
• Brain aneurysm
• Head injury

Effects:

• Increased pressure inside the skull
• Damage to the surrounding brain tissue

3. Transient Ischemic Attack (TIA)- “Mini Stroke”

• Temporary interruption of the blood supply
• Symptoms disappear within minutes or hours
• Acts as an important warning sign for a future major stroke

Global Burden of Strokes

Key global statistics:

• Around 12 million people suffer strokes annually.
• More than half die.
• Nearly two-thirds of survivors experience long-term disability.
• About 87% of stroke deaths occur in low- and middle-income countries (LMICs).

Major reasons:

• Delayed diagnosis
• Poor emergency response
• Limited access to CT scans and stroke units
• Lack of rehabilitation services

Strokes in India

India faces a major stroke challenge because of:

• Large population
• Rising lifestyle diseases
• Limited specialist availability

Statistics:

• Incidence: 108-172 cases per 100,000 people annually
• One-month mortality: 18-42%

Major healthcare gaps:

• Shortage of neurologists
• Shortage of neurosurgeons
• Unequal healthcare access in rural areas

Risk Factors for Stroke

Stroke risk factors can be divided into:

Modifiable factors

These can be prevented or controlled:

• Hypertension (high blood pressure)
• Diabetes
• Smoking and tobacco use
• Obesity
• Physical inactivity
• Unhealthy diet
• Alcohol misuse
• Air pollution
• High cholesterol

Non-modifiable factors

Cannot be changed:

• Increasing age
• Family history
• Genetic factors
• Gender

Warning Signs: FAST Rule

The FAST method helps recognise stroke quickly:

F- Face drooping

• One side of the face becomes weak

A -Arm weakness

• Difficulty lifting one arm

S- Speech difficulty

• Slurred speech or confusion

T- Time to seek help

• Immediate medical attention is necessary

Why Early Treatment Matters

Brain damage increases rapidly with time.

Common medical phrase:

“Time is Brain”

Treatment windows:

• Clot-dissolving drugs are most effective within 4.5 hours
• Mechanical clot removal works best within 6-24 hours in selected patients

WHO World Health Assembly Resolution on Stroke

Recently, the World Health Organisation World Health Assembly adopted its first-ever resolution on stroke.

Main objectives:

1. Recognise stroke as a public health priority

Countries should treat stroke similarly to:

• Heart disease
• Cancer
• Diabetes

2. Strengthen prevention

Measures include:

• Blood pressure control
• Tobacco reduction
• Health education
• Screening for risk factors

3. Improve acute care systems

Countries are encouraged to establish:

• Stroke units
• CT scan facilities
• Emergency referral systems
• Trained personnel

4. Expand rehabilitation support

Focus on:

• Physiotherapy
• Speech therapy
• Occupational therapy
• Psychological support

5. Strengthen long-term care

Support for:

• Survivors with disabilities
• Caregivers
• Community-based rehabilitation

World Health Assembly (WHA)

The World Health Assembly is the decision-making body of WHO.

Functions:

• Determines WHO policies
• Appoints the Director-General
• Approves budgets
• Reviews health priorities

Features:

• Meets annually
• Held in Geneva
• Includes all WHO member countries

Way Forward for India

• Expand stroke centres beyond metropolitan cities
• Improve rural emergency transport systems
• Increase public awareness of FAST symptoms
• Train more neurologists and rehabilitation specialists
• Strengthen preventive healthcare under national health programs

Conclusion

Stroke is increasingly becoming a major public health challenge worldwide and in India. Since most risk factors are preventable, combining early detection, lifestyle modification, rapid treatment, and rehabilitation can significantly reduce deaths and disabilities. The recent WHO resolution marks an important shift toward making stroke prevention and care a global health priority.
