Digital subtraction angiography (DSA) revealed distal occlusion of both posterior cerebral arteries (PCAs) . Which diagnosis best explains this patient’s clinical presentation? A. Hemi-neglect B. Paratonic rigidity C. Urinary incontinence D. Binocular visual loss E. Verbal agnosia Answer: D. Binocular visual loss.  Explanation:  Bilateral distal PCA occlus...

Rapid differentiation between vascular, inflammatory, epileptic, metabolic, and functional etiologies is essential to prevent irreversible neuronal injury. A structured, algorithmic diagnostic approach significantly improves: Diagnostic accuracy Therapeutic timing Visual prognosis Overall neurological outcome 17.1 Emergency Diagnostic Objectives The primary objectives during emer...
