   • MRI: An MRI provides detailed images of the brain and can help identify areas affected by stroke.
   • Angiography: This test uses contrast dye and imaging techniques to visualize blood vessels in the brain, helping to identify blockages or abnormalities.
   • Doppler Ultrasound: This test uses sound waves to create images of blood flow in the arteries, helping to identify blockages or narrowing.
5. Electroencephalogram (EEG): An EEG measures electrical activity in the brain and can help identify seizures or other abnormalities.
6. Echocardiogram: This test uses sound waves to create images of the heart and can help identify conditions like atrial fibrillation that may increase stroke risk.

Treatments for Lateral Occipital Sulcus Strokes:

1. Rehabilitation Therapy: Physical therapy, occupational therapy, and speech therapy can help regain lost abilities and improve quality of life.
2. Medications:
   • Clot-Busting Drugs: Thrombolytics like tissue plasminogen activator (tPA) can help dissolve blood clots causing a stroke if given promptly after symptoms start.
   • Anticoagulants: Drugs like warfarin or direct oral anticoagulants (DOACs) can help prevent blood clots from forming or growing larger.
   • Antiplatelet Drugs: Drugs like aspirin or clopidogrel can help prevent blood clots by inhibiting platelet function.
   • Blood Pressure Medications: Drugs to lower blood pressure may be prescribed to reduce stroke risk.
3. Surgery:
   • Carotid Endarterectomy: This surgery removes plaque buildup from the carotid arteries, reducing the risk of stroke.
   • Angioplasty and Stenting: This procedure uses a balloon to widen narrowed arteries and a stent to keep them open.
   • Surgery to Repair Aneurysms: If a stroke is caused by a ruptured aneurysm, surgery may be needed to repair the blood vessel.
4. Lifestyle Changes:
   • Healthy Diet: Eating a diet low in saturated fats, cholesterol, and sodium and high in fruits, vegetables, and whole grains can help reduce stroke risk.
   • Regular Exercise: Engaging in regular physical activity can help lower blood pressure, cholesterol, and weight, reducing stroke risk.
