An ischemic cerebral artery stroke happens when the blood flow to a part of your brain is suddenly blocked. This blockage can be due to a clot or a piece of fatty material that clogs up a blood vessel. When blood can’t get to your brain, the brain cells can’t get the oxygen and nutrients they need, and they can die.
Types of Ischemic Cerebral Artery Strokes
There are two main types of ischemic cerebral artery strokes:
- Thrombotic Stroke: This type occurs when a clot forms in one of your brain’s blood vessels.
- Embolic Stroke: Here, a clot from another part of your body travels to your brain and gets stuck, blocking a blood vessel there.
Common Causes of Ischemic Cerebral Artery Stroke
Several factors can increase your risk of having an ischemic cerebral artery stroke:
- High Blood Pressure: When your blood pressure is too high, it can damage your blood vessels and make them more likely to have clots.
- Smoking: Smoking can harm your blood vessels and make it easier for clots to form.
- Diabetes: People with diabetes are more likely to have fatty deposits in their blood vessels, which can lead to clots.
- Heart Conditions: Conditions like atrial fibrillation can cause blood clots that might travel to the brain.
- High Cholesterol: Too much cholesterol in your blood can build up on your blood vessel walls and lead to clots.
- Obesity: Being overweight can increase your risk of developing conditions like diabetes and high blood pressure.
- Family History: If someone in your family has had a stroke, you may be at a higher risk.
- Age: As you get older, your risk of stroke increases.
- Gender: Men are more likely to have strokes than women.
- Race: Some racial groups, like African Americans, have a higher risk of stroke.
- Previous Stroke or TIA: If you’ve had a stroke or a transient ischemic attack (TIA) before, you’re at a higher risk of having another one.
- Certain Medications: Some medications can increase your risk of clot formation.
- Sedentary Lifestyle: Not getting enough physical activity can make you more susceptible to stroke.
- Excessive Alcohol Consumption: Drinking too much alcohol can raise your blood pressure and increase your stroke risk.
- Illegal Drug Use: Some drugs can lead to blood vessel problems and stroke.
- Stress: Chronic stress can have a negative impact on your overall health, including your risk of stroke.
- Poor Diet: A diet high in unhealthy fats, salt, and low in fruits and vegetables can contribute to stroke risk.
- Sleep Apnea: This condition, where you stop breathing briefly during sleep, can increase your stroke risk.
- Migraines with Aura: People who experience migraines with visual disturbances (aura) may have a higher risk of stroke.
- Pregnancy and Hormone Therapy: Some women are more at risk during pregnancy or when taking hormone therapy.
Symptoms of Ischemic Cerebral Artery Stroke
Recognizing the signs of a stroke is crucial for seeking help quickly. Here are common symptoms:
- Sudden Weakness or Numbness: You might feel weak or numb in your face, arm, or leg, often on just one side of your body.
- Trouble Speaking: You may have difficulty speaking clearly or understanding others.
- Confusion: Sudden confusion or trouble understanding simple things can occur.
- Vision Problems: You might experience blurred vision, double vision, or loss of vision in one or both eyes.
- Dizziness or Loss of Balance: A sudden loss of balance, coordination, or trouble walking can happen.
- Severe Headache: A severe, abrupt headache with no known cause can be a sign.
- Trouble Swallowing: Difficulty in swallowing or controlling saliva can occur.
- Facial Drooping: One side of your face may droop, making your smile uneven.

If you or someone around you experiences these symptoms, it’s important to call 911 or seek medical help immediately.
Diagnostic Tests for Ischemic Cerebral Artery Stroke
To determine if you’ve had a stroke and which type it is, doctors may use various diagnostic tests:
- CT Scan: This quick and painless test creates detailed images of your brain, helping doctors see if there’s bleeding or a clot.
- MRI Scan: Magnetic Resonance Imaging provides more detailed pictures of your brain and can help detect stroke-related damage.
- Angiography: A special dye is injected into your blood vessels, making them visible on X-rays to pinpoint blockages.
- Ultrasound: This test uses sound waves to create images of your brain’s blood vessels and check for blockages.
- Blood Tests: Doctors may perform blood tests to assess your overall health and rule out other conditions.
- Electrocardiogram (ECG or EKG): This test monitors your heart’s electrical activity to check for irregularities that might cause a stroke.
- Echocardiogram: It’s an ultrasound of your heart to identify any heart-related causes of stroke.
- Lumbar Puncture: In some cases, a sample of cerebrospinal fluid is taken to rule out other conditions.
- Carotid Ultrasound: Specifically checks the carotid arteries in your neck for blockages.
- Transcranial Doppler (TCD): Measures blood flow in the brain’s blood vessels.
- Holter Monitor: A portable ECG device to monitor your heart for an extended period.
- Telemetry Monitoring: Continuous monitoring of heart rate and rhythm.
- Neurological Exam: Your doctor will assess your physical and mental condition, including reflexes and coordination.
- Mini-Mental State Examination (MMSE): A brief test to assess cognitive function.
- National Institutes of Health Stroke Scale (NIHSS): Used to evaluate the severity of stroke symptoms.
- Blood Pressure Monitoring: To check for hypertension, a leading cause of stroke.
- Blood Sugar Testing: To assess glucose levels, especially in diabetic patients.
- Cholesterol Levels: Checking lipid profiles to assess stroke risk factors.
- Coagulation Tests: Evaluating blood clotting factors.
- Electroencephalogram (EEG): Records brain electrical activity to identify seizure-related strokes.
These tests help doctors understand the cause and severity of the stroke, which guides treatment decisions.
Treatments for Ischemic Cerebral Artery Stroke
Immediate treatment is crucial to minimize damage from a stroke. Here are some common treatments:
- Clot-Busting Medication (Thrombolytics): If you arrive at the hospital soon after a stroke starts, doctors may give you medication like tPA (tissue plasminogen activator) to dissolve the clot causing the stroke.
- Antiplatelet Medications: Drugs like aspirin can help prevent new clots from forming.
- Anticoagulants: These medications, such as warfarin or newer oral anticoagulants, can prevent blood clots from forming or growing.
- Blood Pressure Management: Controlling high blood pressure helps prevent further strokes.
- Surgery to Remove Clots: In some cases, doctors may perform a mechanical thrombectomy to physically remove the clot.
- Carotid Endarterectomy: If the blockage is in your carotid artery, surgery to remove the plaque may be necessary.
- Stent Placement: A stent can help keep the blood vessel open after a clot is removed.
- Hemorrhagic Stroke Surgery: If bleeding is causing the stroke, surgery may be needed to repair the blood vessel or remove the blood.
- Rehabilitation: Physical, speech, and occupational therapy can help you regain lost skills and function.
