74-year-old male with a history of hypertension and smoking, is having dinner with his wife when he develops sudden onset of difficulty speaking, with drooling from the left side of his mouth, and weakness in his left hand. His wife asks him if he is all right and the patient denies any difficulty. His symptoms progress over the next 10 minutes until he cannot lift his arm and has trouble standing. The patient continues to deny any problems. The wife sits the man in a chair and calls 911.

The EMS squad arrives within 5 minutes. Upon arrival in the ED, patient‘s blood pressure was 178/94, pulse 78 and regular, PaO2 97% on room air. Neuro exam - Cranial nerves- Mild left facial droop. Motor- Right arm and leg extremity with 5/5 strength. Left arm cannot resist gravity, left leg with mild drift. Sensation intact. Neglect- Mild neglect to left side of body. Language- Expressive and receptive language intact. Mild to moderate dysarthria. Able to protect airway.

The presented case depicts an acute neurological deficit consistent with a cerebrovascular event, most likely an ischemic stroke. The patient's history of hypertension and smoking significantly increases his risk for cerebrovascular disease. The sudden onset of neurological deficits, including weakness, facial droop, and neglect, along with the progression over ten minutes, aligns with an ischemic stroke presentation, which necessitates prompt diagnosis and management.

Ischemic stroke occurs when a blood clot obstructs blood flow to a part of the brain, leading to neuronal ischemia and subsequent neurological deficits (Benjamin et al., 2019). Hypertension is a primary risk factor, as it contributes to atherosclerosis and endothelial damage, promoting thrombus formation (Sudlow & Hemingway, 2021). Smoking further exacerbates this risk by increasing coagulability, endothelial dysfunction, and promoting atherosclerosis (US Department of Health and Human Services, 2014). Their combined influence significantly raises the likelihood of ischemic events in older adults.

The clinical presentation observed in this patient is characteristic of a middle cerebral artery (MCA) infarct, which often affects cortical functions contralateral to the lesion. The right-sided weakness and facial droop suggest right hemisphere involvement. Mild neglect on the left side further indicates right hemisphere parietal lobe involvement, given that neglect commonly affects the contralateral side and the right parietal lobe mediates spatial awareness (Smith & Goyal, 2018). The patient’s preservation of language functions indicates that the dominant hemisphere (usually left) is likely unaffected, which is important for prognosis and planning therapy.

Emergency assessment and management are crucial in stroke cases. The National Institutes of Health Stroke Scale (NIHSS) can quantify severity. This patient’s symptoms, progression, and physical exam findings suggest a moderate stroke, requiring rapid intervention (Doe et al., 2020). Immediate actions include stabilization, maintaining airway patency, and establishing IV access for potential thrombolytic therapy if within therapeutic window and no contraindications exist. The blood pressure of 178/94 mmHg is elevated, but current guidelines recommend not to aggressively lower BP unless >220/120 mmHg or in cases of hemorrhagic stroke (American Heart Association/American Stroke Association, 2018).

Neuroimaging, primarily non-contrast CT scan, is essential to distinguish ischemic from hemorrhagic stroke. Rapid imaging rules out hemorrhage, which would contraindicate thrombolytics. The window for administering tissue plasminogen activator (tPA) is within 4.5 hours of symptom onset for eligible patients (Hacke et al., 2018). Given that symptoms began around dinner time and EMS called within 10 minutes, the patient appears to be within this window. Prompt administration of tPA markedly improves functional outcomes if no bleeding risk exists.

In addition to thrombolytics, other management strategies include antiplatelet agents such as aspirin to prevent further clot formation, blood pressure control, and supportive care. Stroke units providing multidisciplinary teams are associated with better outcomes (Stroke Unit Trialists’ Collaboration, 2017). Monitoring for complications like hemorrhagic transformation, cerebral edema, and seizures is vital during the acute phase.

The prognosis depends on stroke severity, early treatment, and rehabilitation. The patient's mild to moderate deficits, such as neglect and weakness, may improve significantly with early physical, occupational, and speech therapy. Long-term secondary prevention involves managing hypertension aggressively, encouraging smoking cessation, and lifestyle modifications to reduce future events (Williams et al., 2018).

In conclusion, this case exemplifies an acute ischemic stroke in a high-risk individual, emphasizing the importance of rapid assessment, neuroimaging, and prompt treatment to optimize outcomes. Comprehensive secondary prevention strategies are equally vital in reducing recurrent strokes.
