Summary
A new protocol using gait, balance, and cognition tests helps identify normal pressure hydrocephalus patients who benefit from ventriculoperitoneal shunt (VPS) placement. However, symptom recurrence is common one year post-surgery.
Area of Science:
- Neurology
- Neurosurgery
- Physical Medicine and Rehabilitation
Background:
- Normal pressure hydrocephalus (NPH) treatment lacks standardized indications for ventriculoperitoneal shunt (VPS) placement.
- Current NPH management often relies on subjective assessments, leading to variable treatment outcomes.
Purpose of the Study:
- To establish a reliable protocol for identifying NPH patients who will benefit from VPS.
- To evaluate the efficacy and safety of a standardized assessment protocol for VPS candidacy.
Main Methods:
- Developed a protocol involving physical and occupational therapists administering validated tests of gait, balance, and cognition.
- Assessed patients before and after lumbar drain placement using tests like Timed "Up & Go" and Mini Mental Status Exam.
- Conducted a retrospective review of patients treated under this protocol, analyzing VPS candidacy and symptomatic improvement.
Main Results:
- 64% of patients received VPS, with 89.6% reporting initial symptom improvement.
- Significant improvement in Tinetti scores was observed in patients who benefited from VPS compared to the control group.
- 18% experienced subdural fluid collections, and 6% had other complications post-surgery.
Conclusions:
- Standardized pre- and post-cerebrospinal fluid diversion assessments effectively identify NPH patients likely to benefit from VPS.
- The protocol demonstrates a low complication rate, but symptom recurrence affects approximately half of patients within one year.

Increased Intracranial Pressure l: Introduction
Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...
Increased Intracranial Pressure ll: Pathophysiology
Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
