On December 1, 2012, a patient by the name of John Dough walks into the medical assistant’s office. The patient is five foot 11 inches tall, currently he is 70 years old and weighs approximately 211 pounds. The patient has no known allergies does not smoke and has a relatively clean health record.

A nerve conduction study measures the bodies electrical energy by assessing the nerves ability to send a signal. And as a final precaution, the physician wants the patient to receive a ‘MRI’ . A ‘MRI’ or magnetic resonance imaging is a non-invasive imaging technique which uses a magnetic field and radio waves to create an image of the brain and spinal cord.

Once the patient received all of his tests he met with his doctor to discuss the results. On the patients ‘EMG’, results showed Abnormal, spontaneous activity,as well as fibrillations and fasciculations in the patient's tongue. An ‘EMG’ is used to investigate possible motor neurone disease and detect widespread denervation and fasciculations. Fasciculations are not under voluntary control, so they can be easily distinguished from voluntary movement. The patient’s ‘MRI’ results showed that the patients corticospinal tracts were suffering from volume loss,as well as iron deposits in the cortex which contributes to signal loss and neurodegenerative diseases. However Both of these features are present in varying degrees in normal patients, so by itself these results wouldn't stand out. But as results from other tests are put together with these results, a diagnosis can become much easier.
