Stroke

A stroke, also known as a cerebrovascular accident (CVA), is a medical emergency that occurs when blood flow to the brain is disrupted, leading to rapid cell death and potential long-term disability. This condition represents one of the leading causes of death and disability worldwide.

Types of Stroke

Ischemic Stroke

The most common type (approximately 87% of cases), caused by:

• Blood clots (thrombosis)
• Blocked arteries (atherosclerosis)
• Embolisms from other parts of the body (embolism)

Hemorrhagic Stroke

Less common but often more severe, resulting from:

• Burst blood vessels
• Aneurysm
• Uncontrolled hypertension

Risk Factors

Several conditions increase stroke risk:

• Advanced age
• High Blood Pressure
• Diabetes
• Smoking
• Obesity
• Physical inactivity
• Atrial Fibrillation

Warning Signs (FAST)

The FAST acronym helps identify stroke symptoms:

• Face drooping
• Arm weakness
• Speech difficulty
• Time to call emergency services

Treatment

Immediate intervention is crucial for stroke survival and recovery:

Acute Treatment

• Clot-busting medications (Thrombolysis)
• Surgical intervention
• Emergency Medicine

Rehabilitation

• Physical Therapy
• Speech Therapy
• Occupational Therapy
• Neuroplasticity

Prevention

Key preventive measures include:

• Regular Blood Pressure monitoring
• Healthy diet
• Regular exercise
• Anticoagulation therapy when indicated
• Smoking cessation
• Stress Management

Long-term Impact

Strokes can have lasting effects on:

• Motor function
• Speech and language (Aphasia)
• Cognitive abilities
• Mental Health
• Quality of life

Understanding stroke risk factors and recognition of symptoms is crucial for public health, as immediate treatment can significantly improve outcomes and reduce the likelihood of permanent disability.

Research and Innovation

Ongoing research focuses on:

• New treatment modalities
• Prevention strategies
• Neural Recovery
• Biomarkers for early detection
• Artificial Intelligence in stroke diagnosis
