Understanding neurologic disorders requires comprehensive knowledge of their pathophysiology, presentation, differential diagnoses, diagnostic approaches, and treatment options. This paper focuses on stroke, a prevalent and potentially devastating neurological condition, emphasizing a thorough analysis of its mechanisms and clinical management.

Stroke, also known as cerebrovascular accident (CVA), occurs when there is an interruption of blood flow to parts of the brain, resulting in neuronal injury and functional deficits. The pathophysiology involves either ischemia, due to occlusion of cerebral arteries by thrombi or emboli, or hemorrhage when a weakened vessel ruptures, leading to bleeding within the brain tissue (Langhorne et al., 2017). Ischemic stroke accounts for approximately 87% of all strokes, often resulting from atherosclerosis, atrial fibrillation, or other cardioembolic sources, while hemorrhagic strokes are commonly associated with hypertension and vascular malformations (Benjamin et al., 2017).

Risk factors for stroke include modifiable elements such as hypertension, atrial fibrillation, diabetes mellitus, hyperlipidemia, smoking, obesity, sedentary lifestyle, and excessive alcohol consumption. Non-modifiable risks encompass age (particularly over 55 years), family history of stroke or cardiovascular disease, gender (higher incidence in men), and ethnicity, with African Americans exhibiting a higher prevalence partly due to increased hypertension rates (Mozaffarian et al., 2016).

Clinically, stroke presents with sudden neurological deficits. Common signs and symptoms include hemiparesis or hemiplegia, facial droop, aphasia, dysarthria, visual disturbances (e.g., sudden loss of vision in one eye or visual field deficits), dizziness, coordination difficulties, and alterations in consciousness. The presentation varies depending on the affected brain region; for example, infarcts in the middle cerebral artery territory often cause contralateral weakness and language deficits (Feigin et al., 2018). The impact extends beyond the central nervous system, potentially affecting cardiovascular function, causing respiratory compromise, and leading to complications such as aspiration pneumonia, deep vein thrombosis, and depression (Mukherjee et al., 2019).

Differential diagnoses for stroke include transient ischemic attacks (TIA), seizures, brain tumors, multiple sclerosis, hypoglycemia, and migraines with aura. TIAs, for instance, mimic stroke symptoms but resolve without permanent deficits, emphasizing the importance of rapid assessment (Warlow et al., 2014). Distinguishing among these conditions involves thorough clinical evaluation and diagnostic testing.

Diagnostic evaluation hinges on neuroimaging and laboratory studies. Computed tomography (CT) scan is the initial modality to differentiate ischemic from hemorrhagic stroke and to exclude other intracranial pathology. Magnetic resonance imaging (MRI) offers more sensitivity in detecting early ischemic changes. Additional assessments include carotid Doppler ultrasound to evaluate extracranial artery stenosis, echocardiography to identify embolic sources, blood tests for glucose levels, lipid profile, coagulation parameters, and cardiac rhythm monitoring (Kattah et al., 2020). These tests are crucial for confirming stroke type, identifying risk factors, and guiding targeted therapy.

The management of stroke involves acute interventions to restore cerebral perfusion and prevent secondary injury. In ischemic stroke, thrombolytic therapy with tissue plasminogen activator (tPA) within 3 to 4.5 hours of symptom onset remains the standard if no contraindications exist (Emberson et al., 2018). Mechanical thrombectomy is also indicated for large vessel occlusions. Supportive care includes airway management, blood pressure control, and glucose regulation. For hemorrhagic stroke, neurocritical care involves blood pressure lowering, surgical intervention if warranted, and management of intracranial pressure (Zhou et al., 2020).

Long-term treatment focuses on secondary prevention through antiplatelet agents (e.g., aspirin), anticoagulation for atrial fibrillation (e.g., warfarin, direct oral anticoagulants), statin therapy, blood pressure control, lifestyle modifications, and rehabilitation programs to regain neurological function. Referral to physical, occupational, and speech therapy enhances recovery and reduces disability (American Stroke Association, 2018). Multidisciplinary approaches and patient education are vital in decreasing recurrent stroke risk.

Understanding stroke’s pathophysiology, clinical presentation, and management strategies is crucial for timely intervention and improved patient outcomes. Advances in diagnostic imaging and pharmacologic treatments continue to evolve, emphasizing the importance of ongoing research and comprehensive clinical care.
