Amyotrophic Lateral Sclerosis: Diagnostic Tests

Obligatory medical device diagnostics.

  • Electromyography (EMG; measurement of electrical muscle activity) and electroneurography (ENG; measurement of nerve conduction velocity (NLG) of motor and sensory pathways of peripheral nerves) – to detect pathologic (pathological) muscle activity, which is often combined with a decrease in motor units
  • Magnetic resonance imaging (MRI; computer-assisted cross-sectional imaging procedure (using magnetic fields, i.e., without X-rays)) and computed tomography (CT; cross-sectional imaging procedure (X-rays taken from different directions with computer-based evaluation)) – for diagnosing atrophies of the brain and spinal cord and for differential diagnosis versus cervical myelopathy (damage to the spinal cord of the cervical spine)
  • Spirometry (basic examination in the context of pulmonary function diagnostics) – to determine the vital capacity (parameter for the function of the lungs).

Optional medical device diagnostics – depending on the results of the medical history, physical examination and obligatory laboratory parameters – for differential diagnostic clarification.

  • Examination of swallowing functions (video endoscopy if necessary).
