Brief Summary:
In current practice patients with a suspected increase of intracranial pressure (ICP) will undergo a lumbar puncture with measurement of cerebral spinal fluid (CSF) pressure (as a marker for ICP). A lumbar puncture is an invasive and sometimes painful procedure. Using a new type of ICP monitor (HeadSense) it is possible to measure ICP non-invasively through an acoustic signal

Condition or disease Intervention/treatment Phase
Intracranial Hypertension Device: HS-1000 Not Applicable

Detailed Description:

In this study we will prospectively collect relevant clinical data on 60 neurological patients, who are being referred for an elective lumbar puncture (eg. suspected multiple sclerosis, raised intracranial hypertension, etc). Each enrolled patient will be monitored in parallel to the lumbar puncture with the HeadSense ICP monitor. Subjects who meet the study inclusion and exclusion criteria will be enrolled in the study.

Step 1: 10 minute measurement of HeadSense monitor. Once the patient is inclined with his upper body 30 degrees to the bed the pressure values, the clinical procedure can begin. The device must be preset in a continuous monitoring mode. The continuous monitoring allows a loop of measurements for an unlimited time in a rate of four measurements per minute.

Step 2: 10 minute measurement of HeadSense monitor in supine position.

Step 3: Patient will be placed in a left lateral position. The lumbar puncture will be done and CSF pressure will be measured following standard procedures.

Step 4: 10 minute measurement of HeadSense monitor in supine position.

Lumbar puncture and HeadSense measurement will be done by two different doctors and they will not share measurement values during the procedure.

After the study the patient's ears will be examined for internal ear infection or irritation that might be caused by the ear buds. Patient adverse events will be documented on the case report forms in case they occurred and the family or advocate of the patient will be informed. In case of clinical relevant adverse events appropriate clinical action will be taken.

As the procedure does not affect the patient management, there is no need to provide any specific medical care related to the trial. Patients will receive the relevant clinical care related to their clinical management, without any consideration to their participation in the trial.

Arm Intervention/treatment
Experimental: HS-1000 recording
ICP monitoring will be done with the HS-1000 to compare to CSF measurement from lumbar puncture (per clinical protocol without any change in the patient's management). HS-1000 ICP monitoring intervals last 10 minutes.
Device: HS-1000

Primary Outcome Measures :
  1. Number of ICP values obtained by the HeadSense device that correlate to ICP using current standards [ Time Frame: 10 minutes ]

Secondary Outcome Measures :
  1. Incidence of Adverse events (AEs) [ Time Frame: 48 hours from the end of monitoring with the HS-1000 ]
