Outcome Measures

Primary Outcomes (1)

  • Cochlear damage

    Assess the frequency and timely evolution of sensorineural hearing loss by using OAE/WBT and audiometry.

    Day1-90

Secondary Outcomes (3)

  • Vestibular function loss

    Day 1-90

  • Identifying biochemical markers in CSF during a CNS infection

    Day 1-90

  • Cognitive impairment

    Day 90

Study Arms (5)

Cohort with CNS infections

Otoacoustic emissions (OAE), Wide Band Tympanometry (WBT), Vestibular function tests. Audiometry. MOCA, eGOS are cognitive tests. Biomarker is a protein found in the inner ear examined in the cerebral fluid.

Diagnostic Test: Vestibular functionDiagnostic Test: OAE/WBTDiagnostic Test: BiomarkerDiagnostic Test: MOCA, eGOSDiagnostic Test: Audiometry

OAE/WBT control: Healthy individuals

Otoacoustic emissions in normal position with head. Otoacoustic emission in different head positions.

Diagnostic Test: OAE/WBT

OAE/WBT control: Systemic infection

Otoacoustic emission during admission

Diagnostic Test: OAE/WBT

OAE/WBT control: ICP changes

Otoacoustic emission on patients without an CNS infection before and after elective lumbare puncture with measurement of intracranial pressure (ICP).

Diagnostic Test: OAE/WBT

Biomarker control

Inner ear biomarkers in patients without CNS infection. Inner ear fluid examination from patients that underwent elective cochlea implantation.

Diagnostic Test: Biomarker
