2.1. Acute Neurological Emergencies: Precision in Diagnosis and Care

Managing acute neurological events demands immediate and precise interventions, where minutes can determine outcomes.

• Transient Ischemic Attack vs Stroke: Differentiating between transient ischemic attack (TIA) vs stroke remains a cornerstone of acute neurology. While both share identical sudden-onset symptoms (e.g., unilateral weakness, speech difficulty, visual disturbances), a TIA is characterized by transient symptoms resolving within 24 hours (most often within minutes) without evidence of acute infarction on diffusion-weighted MRI (DWI-MRI). Conversely, a stroke involves irreversible brain tissue damage. Recent guidelines emphasize that TIA is a warning sign of impending stroke, with approximately 1 in 5 TIA patients experiencing a full stroke within 90 days. Rapid evaluation, typically within 24 hours of symptom onset, is crucial. This involves immediate neurological assessment, comprehensive neuroimaging (MRI with DWI is preferred over CT to detect subtle infarcts), and vascular imaging (CT or MR angiography) to identify the etiology (e.g., carotid stenosis, cardiac emboli). Management focuses on aggressive secondary prevention, including antiplatelet therapy, anticoagulation for embolic sources (e.g., atrial fibrillation), statins, and risk factor modification (hypertension, diabetes). For high-risk TIA (e.g., those with carotid stenosis), urgent revascularization procedures may be indicated, directly influencing future stroke risk.

• Neuro ICU Protocols for Physicians: The neurocritical care unit (NICU) has become indispensable for managing life-threatening neurological conditions. Advanced neuro ICU protocols for physicians are constantly refined to optimize patient outcomes. These protocols encompass stringent guidelines for intracranial pressure (ICP) management in traumatic brain injury (TBI) and hemorrhagic stroke, continuous electroencephalography (EEG) monitoring for non-convulsive seizures in critically ill patients, and targeted temperature management for post-cardiac arrest cerebral injury. Key elements include standardized pathways for acute stroke management (including thrombectomy and thrombolysis decisions), status epilepticus escalation protocols, and meticulous fluid and electrolyte management to prevent cerebral edema. The emphasis is on early recognition, rapid intervention, and continuous multimodal monitoring, often leveraging artificial intelligence (AI) to predict deterioration and guide timely interventions, ensuring that neuro ICU protocols for physicians align with the latest evidence.

2.2. Chronic Neurological Diseases: Evolving Treatments and Diagnostics

The increasing lifespan globally has amplified the prevalence of chronic neurological conditions, particularly neurodegenerative diseases in elderly populations, necessitating groundbreaking therapeutic and diagnostic advancements.
