Introduction Intracranial hemorrhage (ICH) is a potentially life-threatening medical event that may occur spontaneously; or in the setting of head trauma or surgical intervention. The etiology of non-traumatic ICH, which has an incidence of >25 per 100,000 person years (1), is diverse and includes hypertension, stroke, ruptured aneurysm, vasculopathy, dural venous sinus thrombosis, arteriovenous fistula, malignancy, anticoagulant use and, rarely, inflammatory disease.

1. Introduction Delirium occurs frequently in critically ill patients and has consistently been associated with higher mortality and worse overall outcomes (1). However, the diagnosis and detection of delirium remains challenging in many patient populations, as existing screening tools are unreliable in patients with stroke (2), neurocritical illness (3), and dementia (4).
