Non-Aneurysmal Internal Carotid Artery Stroke, often referred to as NAICAS, is a condition where a stroke occurs in the internal carotid artery without an associated aneurysm. In this article, we will explain NAICAS in simple terms, covering its types, causes, symptoms, diagnostic tests, treatments, drugs, and surgical options.
Types of Non-Aneurysmal Internal Carotid Artery Stroke:
- Embolic Stroke: Occurs when a blood clot or debris from another part of the body travels to the internal carotid artery, blocking blood flow.
- Thrombotic Stroke: Caused by the formation of a blood clot within the internal carotid artery itself, restricting blood flow.
Common Causes of NAICAS:
- High Blood Pressure: Uncontrolled hypertension is a major risk factor.
- Atherosclerosis: Build-up of plaque in the artery walls.
- Smoking: Increases the risk of blood clots and plaque formation.
- Diabetes: Elevated blood sugar levels can damage blood vessels.
- High Cholesterol: Elevated cholesterol levels contribute to plaque formation.
- Obesity: Excess body weight can lead to hypertension and diabetes.
- Family History: A genetic predisposition to stroke.
- Aging: Risk increases with age, particularly after 55.
- Heart Conditions: Irregular heart rhythms and valve problems.
- Previous Stroke: A prior history of stroke raises the risk.
- Sedentary Lifestyle: Lack of physical activity.
- Drug Abuse: Illicit drug use can lead to stroke.
- Excessive Alcohol Consumption: Increases blood pressure.
- Migraines: Especially with aura, can increase stroke risk.
- Birth Control Pills: Especially in combination with smoking.
- Hormone Replacement Therapy: Can raise stroke risk in postmenopausal women.
- Sleep Apnea: Interruption of breathing during sleep.
- Blood Disorders: Conditions like sickle cell anemia.
- Infections: Certain infections can trigger stroke.
- Neck Trauma: Injury to the neck area can cause stroke.
Common Symptoms of NAICAS:
- Sudden Weakness: Typically on one side of the body.
- Numbness: Often affecting the face, arm, or leg.
- Difficulty Speaking: Slurred speech or confusion.
- Vision Problems: Blurred or double vision.
- Severe Headache: Usually a sudden, intense headache.
- Dizziness: Loss of balance and coordination.
- Trouble Swallowing: Difficulty in swallowing.
- Loss of Consciousness: Fainting or blacking out.
- Fatigue: Sudden and extreme tiredness.
- Memory Problems: Difficulty remembering things.
- Trouble Walking: Lack of coordination.
- Facial Drooping: One side of the face may droop.
- Difficulty Understanding: Confusion and trouble processing information.
- Nausea and Vomiting: May accompany other symptoms.
- Sensory Changes: Altered sensation in limbs.
- Chest Pain: Especially in women, it can be a symptom.
- Rapid Breathing: Shortness of breath.
- Loss of Bowel or Bladder Control: Rare but possible.
- Emotional Changes: Mood swings or personality changes.
- Seizures: Uncontrolled muscle movements.
Diagnostic Tests for NAICAS:
- CT Scan: Provides detailed images of the brain.
- MRI: Offers more detailed brain images than CT.
- Angiography: Visualizes blood vessels, including the carotid arteries.
- Doppler Ultrasound: Measures blood flow in the carotid arteries.
- Electrocardiogram (ECG or EKG): Checks heart rhythm.
- Echocardiogram: Examines heart function.
- Blood Tests: Can reveal underlying conditions.
- Carotid Artery Imaging: Identifies blockages or narrowing.
- Lumbar Puncture: Checks for bleeding or infection in the brain.
- Holter Monitor: Records heart activity over 24 hours.
- Transcranial Doppler: Measures blood flow in the brain.
- Carotid Duplex: Combines ultrasound and Doppler to assess carotid arteries.
- Cerebral Angiography: Examines blood vessels in the brain.
- Electroencephalogram (EEG): Measures brain activity.
- Chest X-ray: May reveal heart or lung issues.
- Blood Pressure Monitoring: To detect hypertension.
- Blood Sugar Test: Checks for diabetes.
- Lipid Profile: Measures cholesterol levels.
- Coagulation Tests: Evaluate blood clotting ability.
- Genetic Testing: Identifies genetic risk factors.
Treatments for NAICAS:
- Medications: To lower blood pressure, control diabetes, and prevent blood clots.
- Antiplatelet Drugs: Prevent clot formation.
- Anticoagulants: Prevent and treat blood clots.
- Thrombolytic Therapy: Dissolves blood clots.
- Carotid Endarterectomy: Surgical removal of plaque from the carotid artery.

- Aneurysm Repair: If an aneurysm is discovered.
- Anti-seizure Medications: If seizures occur.
- Depression Treatment: Counseling or medication.
- Infection Control: If an infection triggered the stroke.
- Breathing Support: Ventilator if needed.
- Pain Management: For post-stroke headaches and discomfort.
- Speech and Swallowing Exercises: Improve communication and eating.
- Assistive Devices: Wheelchairs, walkers, or canes.
- Emotional Support: Counseling for emotional well-being.
- Social Support: Encouragement from family and friends.
- Adaptive Equipment: Devices to aid in daily living.
- Blood Pressure Monitoring: Regular checks at home.
- Dietary Changes: Reducing salt and saturated fats.
- Exercise Programs: Tailored to individual abilities.
- Smoking Cessation Programs: Support to quit smoking.
- Medication Management: Ensuring proper dosage and adherence.
Common Drugs Used in NAICAS Treatment:
- Aspirin: An antiplatelet medication.
