Diagnosis & Tests
How is the disease diagnosed?
The diagnosis is based on special tests. One test that is used is electromyography or EMG for short. Another is a nerve conduction study, or NCV. A neurological exam and a clinical history are also used. Other diseases that mimic ALS, such as conditions known as cervical spinal or lumbar stenosis, must be ruled out.
