Clinical Causes: Atherosclerosis: buildup of fatty deposits within the blood vessel walls, leading to narrowing or blockage. Embolism: a clot or debris traveling through the bloodstream and lodging in the artery. Arterial stenosis: natural narrowing or constriction of the artery that reduces blood flow. Vasospasm: sudden constriction of blood vessels, decreasing blood flow. Other factors such as high blood pressure, smoking, high cholesterol, and blood clotting disorders can also contribute to the narrowing or blockage of cerebral arteries.

Key Symptoms: Sudden weakness or numbness, especially on the right side of the body. Difficulty speaking or understanding speech. Sudden confusion or trouble with cognitive functions. Visual disturbances in one or both eyes. Sudden headache that is severe or different from usual headaches. Loss of coordination or balance, making walking or standing difficult. Partial or complete paralysis on the affected side.

Diagnosis Path: Computed tomography (CT) scan to detect bleeding or infarction in the brain. Magnetic resonance imaging (MRI) to provide detailed images of brain tissue and blood vessels. Magnetic resonance angiography (MRA) or CT angiography to visualize blood flow and identify occlusions or stenosis in the cerebral arteries. Doppler ultrasound to assess blood flow in cerebral vessels. Blood tests to evaluate clotting factors and related risk factors.

Treatment Protocols: Emergency treatment with clot-dissolving medications (thrombolytics) within the appropriate time window. Antiplatelet agents such as aspirin to prevent further clot formation. Anticoagulants if blood clotting issues are identified. Surgical procedures like carotid endarterectomy or angioplasty with stenting in cases of significant artery narrowing. Management of underlying health conditions like high blood pressure, diabetes, and high cholesterol. Rehabilitation therapies including physical, occupational, and speech therapy to regain lost functions.
