EEG & Neurophysiology Investigation
Clinical neurophysiology departments provide a range of investigations including electroencephalography (EEG), nerve conduction studies (NCS) with electromyography (EMG), and evoked potentials (EP). These investigations constitute the largest part of a clinical neurophysiologist’s workload.
EEG is most often used to diagnose children and adults with epilepsy (the most common serious neurological condition), while NCS and EMG are required for the management of peripheral nerve disorders, such as entrapment neuropathy (carpal tunnel syndrome, ulnar neuropathy, etc), generalized peripheral neuropathies (eg inherited or diabetic neuropathy) and other diseases of nerve and muscle, such as motor neuron disease and myasthenia gravis. EPs are complementary tests used in the diagnosis of multiple sclerosis, the assessment of coma in critically ill people, and in monitoring surgery of the brain and spine to ameliorate unintended damage and consequent disability.
