[Diagnostic value of brainstem auditory evoked potentials (author's transl)]

Area of Science:

• Neuroscience
• Clinical Neurology
• Diagnostic Tools

Context:

• Brainstem Auditory Evoked Potentials (BAEP) are utilized for neurological diagnosis.
• Normative data were established from 50 healthy subjects (mean age 35).
• Interpretation criteria were defined for clinical application.

Purpose:

• To evaluate the efficacy of BAEP in diagnosing neurological disorders.
• To assess BAEP's utility in identifying multiple sclerosis and posterior fossa tumors.
• To determine BAEP's contribution to diagnosing conditions like optic neuritis and vascular diseases.

Summary:

• BAEP demonstrated significant abnormality rates in definite (67%), probable (41%), and possible (19%) multiple sclerosis cases.
• The study highlights BAEP's diagnostic value in progressive paraplegia, optic neuritis, and suspected posterior fossa tumors.
• BAEP provided crucial information regarding tumor location, rostral extension, and infiltration, especially when CT scans were equivocal.

Impact:

• BAEP serves as a reliable diagnostic aid, complementing clinical examination and imaging techniques.
• This evaluation underscores the importance of BAEP in complex neurological assessments.
• Findings support the integration of BAEP into the diagnostic workup for various central nervous system disorders.
