Continuous quantitative electroencephalography for early detection of acute low-pressure obstructive hydrocephalus in aneurysmal subarachnoid hemorrhage: illustrative case

ALPH presents with paradoxical ICP dynamics, complicating its diagnosis. Careful monitoring, including EEG, can provide an early indication of neurological deterioration and guide timely intervention. This case underscores the importance of considering ALPH in patients with aSAH who show clinical worsening without corresponding increases in ICP. Tailoring management to address the atypical pressure dynamics is crucial for improving outcomes. https://thejns.org/doi/10.3171/CASE24612.
