Stroke
A stroke can be life-threatening and debilitating. It can occur with little warning. If you or a loved one experience stroke symptoms, act quickly by calling 911. So why does it happen? A stroke occurs when the blood supply to part of your brain is interrupted or reduced, depriving brain tissue of oxygen and nutrients. Within minutes, brain cells begin to die, and is considered a medical emergency. Timely treatment is crucial to minimize brain damage and potential complications. Recognizing stroke symptoms, understanding its causes, and being aware of available treatments can make a significant difference in improving patient outcomes. First Choice Neurology has a team of stroke specialists and operates more than 60 Care Centers across multiple Florida counties, offering services at 45+ major hospitals for stroke patients.
Strokes are the third leading cause of death in the United States. Nearly three-quarters of all strokes occur in people over the age of 65. The risk of having a stroke more than doubles each decade after the age of 55. About 600,000 of these are first attacks, and 185,000 are recurrent attacks. More than 140,000 people die each year from strokes in the United States.
5 Key Facts About Stroke
FACT 1: Stroke kills brain cells
A stroke happens when a clot or rupture interrupts blood flow to the brain. Without oxygen-rich blood, brain cells die.
FACT 2: Types of stroke (Ischemic, Hemorrhagic, TIA)
Ischemic caused by a clot, Hemorrhagic caused by a rupture, and Transient Ischemic Attack (TIA) or “warning stroke” is caused by a temporary blockage.
FACT 3: About one in four stroke survivors is at risk for another stroke
Fortunately, up to 80 percent of second clot-related strokes may be preventable.
FACT 4: Prevention is key
Had a stroke? Work with your doctor to identify the cause and create a plan to prevent another. This may include managing high blood pressure, making healthy lifestyle choices, and taking medications as recommended by your doctor.
FACT 5: Time lost is brain lost
Now that you know prevention, here’s how you spot one.
Learn the FAST warning signs.
Stokes can happen at any age. High blood pressure is a high-risk factor. Up to 80 percent of strokes are preventable. Having a family history of strokes increases your chances. About every 40 seconds someone in the United States has a stroke.
Warnings Signs of Strokes
Warnings Signs of StrokesEarly detection of a stroke is crucial to reducing its impact. The American Stroke Association recommends the FAST acronym as an easy way to identify stroke symptoms:
• Face drooping: One side of the face may droop or feel numb. Ask the person to smile—if the smile is uneven, it could indicate a stroke.
• Arm weakness: Sudden weakness or numbness in one arm, making it difficult to lift both arms evenly.
• Speech difficulty: Slurred or incoherent speech is a warning sign. Ask the person to repeat a simple phrase.
• Time to call 911: If any of these signs are present, seek immediate medical help.
Other symptoms of stroke may include:
• Sudden confusion or trouble understanding speech
• Blurred or loss of vision in one or both eyes
• Severe headache with no known cause
• Dizziness, loss of balance, or difficulty walking
Recognizing these symptoms early and acting fast can help prevent long-term damage or even death.
Common Causes of Stroke
Several risk factors contribute to stroke, and they are generally classified into two categories: modifiable and non-modifiable risk factors.
Modifiable Risk Factors:
These are factors that can be controlled or managed with lifestyle changes and medical treatment:
• High blood pressure (Hypertension): The leading cause of strokes, high blood pressure can weaken arteries over time.
• Smoking: Tobacco use doubles the risk of ischemic stroke.
• Diabetes: Uncontrolled blood sugar levels increase stroke risk.
• High cholesterol: Excess cholesterol can lead to plaque buildup, blocking arteries.
• Obesity and lack of exercise: Sedentary lifestyles contribute to multiple stroke risk factors.
• Heart disease: Conditions like atrial fibrillation increase the risk of blood clots leading to strokes.
• Excessive alcohol consumption: Heavy drinking raises blood pressure and increases stroke risk.
Non-Modifiable Risk Factors:
These are factors beyond an individual’s control:
• Age: Stroke risk increases with age, especially after 55.
• Gender: Men are more likely to have strokes, but women have a higher mortality rate.
• Family history: A genetic predisposition can increase stroke risk.
• Previous stroke or transient ischemic attack (TIA): Individuals who have had a prior stroke or TIA are at a higher risk of future strokes.
Preventing a Stroke
The good news is that up to 80% of strokes are preventable through lifestyle changes and medical intervention. Here are key prevention strategies:
• Manage blood pressure – Use medication, diet, and exercise to keep it within a healthy range.
• Control cholesterol and blood sugar – Regular screenings and management help reduce risk.
• Eat a heart-healthy diet – Focus on fruits, vegetables, whole grains, lean proteins, and low sodium.
• Stay active – Aim for at least 30 minutes of moderate exercise most days.
• Quit smoking – Smoking doubles your risk of ischemic stroke.
• Limit alcohol – Excessive drinking raises blood pressure and stroke risk.
• Maintain a healthy weight – Obesity increases the risk of stroke and other chronic diseases.
Types of Stroke
There are three main types of strokes, each with different causes and treatment approaches:
1. Ischemic Stroke: The most common type, accounting for about 87% of all strokes. It occurs when a blood clot or plaque blocks an artery supplying blood to the brain. Ischemic strokes are often caused by atherosclerosis or embolisms.
2. Hemorrhagic Stroke: This occurs when a weakened blood vessel bursts, leading to bleeding in the brain. High blood pressure and aneurysms are the most common causes.
3. Transient Ischemic Attack (TIA): Also known as a "mini-stroke," a TIA is a temporary blockage of blood flow that resolves within minutes or hours without causing permanent damage. However, it is a serious warning sign of an increased risk of a full stroke.
When to See a Doctor and What Kind of Doctor for a Stroke
If you have risk factors for stroke or a history of heart or vascular issues, it’s important to see a neurologist or stroke specialist. These doctors are trained to evaluate stroke risk, diagnose underlying conditions, and develop personalized prevention plans.
A neurologist may:
• Conduct a thorough medical history and physical exam.
• Recommend diagnostic tests like brain imaging (MRI or CT scan), carotid ultrasounds, or blood tests.
• Monitor and treat underlying conditions like hypertension, diabetes, or atrial fibrillation.
• Prescribe medications to reduce stroke risk (e.g., blood thinners, statins, or antiplatelet drugs).
• Recommend lifestyle modifications and possibly refer you to a dietitian or physical therapist.
Stroke Treatment Options
Prompt medical treatment is critical for minimizing stroke damage. The treatment depends on the type of stroke and how quickly medical care is administered.
• For Ischemic Stroke – Medications such as tissue plasminogen activator (tPA) can dissolve clots if given within 3 to 4.5 hours of symptom onset. In some cases, doctors may perform a procedure called a thrombectomy to remove the clot.
• For Hemorrhagic Stroke – Treatment focuses on controlling bleeding and reducing pressure in the brain. Surgery may be needed to repair damaged blood vessels.
• Rehabilitation – Most stroke survivors need rehab to regain lost functions. This can include physical therapy, occupational therapy, speech therapy, and neuropsychological support.
Stroke Rehabilitation and Recovery
Recovery from a stroke depends on the severity of brain damage and how quickly treatment is received. Stroke rehabilitation may include:
• Physical therapy: Helps regain mobility, strength, and coordination.
• Speech therapy: Assists in overcoming communication difficulties.
• Occupational therapy: Helps patients relearn essential daily tasks.
• Medication management: Prevents recurrent strokes by controlling risk factors such as high blood pressure and cholesterol.
