Diagnosis
ENG (Electroneurography)
Electroneurography is used to examine the functional state of peripheral nerves (nerves outside the brain and spinal cord). The principle is based on electrical stimulation of the nerve being examined. The measurements are taken with a few very short electrical impulses, are somewhat uncomfortable, but are generally well tolerated and usually do not take long.
Lumbago puncture
After explanation, a lumbar puncture involves inserting a special needle into the lumbar spine to extract a small amount of cerebrospinal fluid (CSF) from the spinal canal. The procedure takes approximately 10 minutes. After a half-hour rest period, the patient can leave the doctor's office. A blood coagulation test is required before every lumbar puncture. The use of anticoagulant medications may need to be discontinued a few days prior to the procedure.
EMG (Electromyography)
Electromyography (EMG) measures electrical activity in selected muscles. This electrical activity allows for the assessment of muscle and nerve function. Based on this information, various muscle and nerve disorders can be diagnosed. The pain experienced when the electromyography needle is inserted is quite similar to that of a simple blood draw. The needle movements during the examination are generally painless, as the interior of the muscles is largely insensitive to pain.
Doppler/Duplex Sonography
Doppler/duplex sonography of the brain-supplying vessels, both inside and outside the head, is performed like any other ultrasound examination. This allows for the diagnosis of narrowing (stenosis) and arteriosclerotic changes in the arteries. The examination is very important in determining the causes of strokes and cerebrovascular disorders, and as a preventative screening, especially in the presence of risk factors such as high blood pressure. The examination is painless.
Evoked potentials
Evoked potentials are used to test the conductivity of nerve pathways. We offer the following examinations: VEP – Visually evoked potentials for assessing the visual pathway. (F)AEP – (Early) auditory evoked potentials for assessing the central and peripheral auditory pathways. SSEP – Somatosensory evoked potentials for assessing the somatosensory pathways.
Nerve/muscle sonography
High-resolution ultrasound probes are used to examine peripheral nerves and muscles. This painless method allows for the diagnosis of localized nerve damage, such as in carpal tunnel syndrome or after accidents, as well as certain polyneuropathies. Muscle sonography is also useful in diagnosing motor neuron diseases.
