Positive-outcome predictors of lumbar drain trial in normal-pressure hydrocephalus patients


  • Normal-pressure hydrocephalus (NPH) patients with no history of stroke and who have disproportionate subarachnoid spaces are more likely to have positive outcomes following short-term lumbar drain (LD).

Why this matters

    A LD trial is performed to confirm diagnosis of NPH and predict response to ventriculoperitoneal shunt surgery; however, it is unknown which patients respond best to it.
