Stroke: The Comprehensive Guide

What is a Stroke?

A stroke (medically: cerebrovascular accident or brain attack) is an acute disruption of blood flow to the brain. Brain cells are no longer adequately supplied with oxygen and nutrients, which can lead to their death. About 1.9 million brain cells die per minute – that's why quick action is vital.

Stroke is the second leading cause of death worldwide and a leading cause of disability. Globally, approximately 15 million people suffer a stroke annually, with about 5 million dying and another 5 million being permanently disabled.

Types of Stroke

Doctors distinguish between two main types of stroke:

Ischemic Stroke (80-87% of all cases)

In ischemic stroke, a blood vessel in the brain is blocked by a blood clot (thrombus). This can occur through:

• Thrombosis: Blood clot forms directly in the brain vessel
• Embolism: Blood clot travels from another part of the body to the brain
• Hemodynamic infarction: Reduced blood flow due to low blood pressure

Hemorrhagic Stroke (13-20% of all cases)

Here, a blood vessel in the brain ruptures and causes bleeding. Types include:

• Intracerebral hemorrhage: Bleeding within the brain tissue itself
• Subarachnoid hemorrhage: Bleeding between the brain and brain membranes

Recognizing Stroke Symptoms

Stroke symptoms can be varied and depend on which area of the brain is affected. Important: Even if symptoms are brief and disappear, emergency medical services should be called immediately!

Common Stroke Symptoms:

• Sudden paralysis or weakness on one side of the body (hemiparesis)
• Speech and language comprehension disorders (aphasia)
• Vision problems in one or both eyes
• Sudden severe headache of unknown cause
• Dizziness and balance disorders
• Nausea and vomiting
• Consciousness disorders up to unconsciousness
• Swallowing difficulties (dysphagia)

Causes and Risk Factors

A stroke doesn't occur suddenly but is usually the result of various risk factors that develop over years. These can be divided into modifiable and non-modifiable factors.

Non-modifiable Risk Factors:

• Age: Risk doubles every 10 years after age 55
• Gender: Men have slightly higher risk than women
• Genetic predisposition: Family history of stroke
• Ethnicity: Certain populations have higher risks

Modifiable Risk Factors:

• High blood pressure (hypertension): Most important risk factor
• Diabetes mellitus: Increases risk 2-3 fold
• Smoking: Doubles stroke risk
• Atrial fibrillation: Heart rhythm disorder increases embolism risk
• High cholesterol levels: Promote atherosclerosis
• Obesity: Especially abdominal fat is problematic
• Physical inactivity: Promotes many other risk factors
• Alcohol abuse: Increases bleeding risk
• Stress: Chronic stress strains the cardiovascular system

Treatment in the Acute Phase

Stroke treatment is a race against time. In medicine, the principle is: "Time is Brain" – every minute counts to save brain tissue.

First Aid for Stroke:

• Immediately call emergency services – even if only suspected!
• Calm the patient and don't leave them alone
• Position upper body slightly elevated (30°)
• Don't give anything to drink or eat
• If unconscious: Recovery position
• Note symptom onset time for doctors

Clinical Treatment:

In the hospital, quick diagnosis is performed using CT or MRI to distinguish between ischemic and hemorrhagic stroke.

For Ischemic Stroke:

• Thrombolytic therapy: Dissolving blood clot with medications (up to 4.5 hours after symptom onset)
• Thrombectomy: Mechanical removal of clot (possible up to 24 hours)
• Stroke unit: Monitoring in specialized stroke unit

For Hemorrhagic Stroke:

• Blood pressure management: Controlled lowering of blood pressure
• Neurosurgery: Surgical relief for large hemorrhages
• Intensive care: Monitoring of vital functions

Rehabilitation After Stroke

Rehabilitation begins in the acute hospital and is crucial for recovery. Modern rehabilitation concepts utilize neuroplasticity of the brain – the ability to form new connections and take over functions.

Phases of Rehabilitation:

Phase A - Acute Treatment (0-3 days)

• Stabilization of vital functions
• Early mobilization in bed
• First physiotherapy measures

Phase B - Early Rehabilitation (1-6 weeks)

• Intensive physiotherapy
• Speech therapy for language disorders
• Occupational therapy for daily activities
• Neuropsychological treatment

Phase C - Continuing Rehabilitation (6 weeks - 6 months)

• Outpatient or inpatient rehabilitation clinic
• Training of daily activities
• Vocational reintegration
• Family counseling

Phase D - Long-term Rehabilitation (from 6 months)

• Outpatient therapies
• Support groups
• Long-term care for severe consequences

Life After Stroke

A stroke changes life – not only for those affected but also for their family members. With the right support and attitude, however, a fulfilling life is possible.

Possible Consequences and Their Management:

Physical Consequences:

• Hemiparesis: Paralysis of one side of body – training and assistive devices help
• Spasticity: Muscle stiffness – treatment with medications and therapy
• Coordination disorders: Improvement through targeted training

Cognitive Consequences:

• Memory problems: Learn compensation strategies
• Concentration disorders: Gradual increase in workload
• Attention deficits: Special training programs

Psychological Consequences:

• Depression: Common after stroke – seek professional help
• Anxiety: About recurrent stroke – education and relaxation techniques
• Personality changes: Patience and understanding are important

Stroke Prevention

The good news: 90% of all strokes are preventable! Through a healthy lifestyle and control of risk factors, stroke risk can be significantly reduced.

Effective Prevention Measures:

Control Blood Pressure:

• Regular monitoring (optimal: under 140/90 mmHg)
• Low-salt diet (under 6g daily)
• Weight reduction if overweight
• Medication treatment if necessary

Heart-Healthy Living:

• Don't smoke: Risk halves after one year of quitting
• Moderate alcohol consumption: Maximum 1-2 drinks per day
• Treat atrial fibrillation: Blood thinning if needed
• Lower cholesterol: Target LDL under 100 mg/dl

Stay Active:

• Regular exercise: At least 150 minutes moderate activity per week
• Cardio exercise: Swimming, cycling, walking
• Strength training: 2x per week for muscle building
• Daily activity: Take stairs, walk

Eat Healthy:

• Mediterranean diet: Lots of vegetables, fruits, fish, olive oil
• Whole grains: Instead of refined flour
• Less red meat: Maximum 2-3 times per week
• Adequate hydration: 1.5-2 liters water daily

Guide for Family Caregivers

Family members of stroke patients face special challenges. They are often overwhelmed and need support themselves.

Help in the Acute Phase:

• Stay calm: Even though it's difficult
• Gather information: Ask doctors about prognosis and treatment
• Show presence: Regular visits, even if patient doesn't respond
• Self-care: Don't forget your own needs

Frequently Asked Questions (FAQ)

Can stroke be completely prevented?

No, 100% protection is not possible. However, through healthy lifestyle and control of risk factors, the risk can be reduced by up to 90%.

How long does rehabilitation take?

This varies greatly individually. First successes often show after weeks, but rehabilitation can take months to years. Important: The brain can learn throughout life!

Can you return to work after a stroke?

Many affected people return to work. Depending on the consequences, workplace adaptations or professional reorientation may be necessary. Vocational training centers provide support.

Is a second stroke likely?

The risk of recurrent stroke is increased but can be significantly reduced through consistent secondary prevention (medications, lifestyle).

How do I explain stroke to children?

Honestly but age-appropriately. Explain that the brain was sick and now needs to learn again. Children often understand better than expected and can be important supporters.

Conclusion: Hope and Perspective

A stroke fundamentally changes life – but it doesn't mean the end. With modern medicine, intensive rehabilitation, and the will of those affected, remarkable successes are possible.

Important: Every stroke is different, every course individual. What applies to one patient doesn't have to apply to others. That's why individual, expert care is so important.

Research continues to make progress. New therapies, better medications, and innovative treatment methods constantly open new possibilities. The message is: It's worth fighting!
