How are neurological disorders diagnosed?

MRI. This test uses a combination of large magnets, radio waves, and a computer to make detailed images of organs and structures within the body. Electrodiagnostic tests, such as electromyography (EMG) and nerve conduction velocity (NCV). These tests evaluate and diagnose disorders of the muscles and motor neurons.

Are neurological problems hard to diagnose?

Neurological conditions can be difficult to diagnose because symptoms of one condition can be similar to another. Non-neurological conditions can sometimes mimic the symptoms of neurological conditions.

Why does a neurologist look in your eyes?

Not only are we looking to see if your pupils constrict, but as functional neurologists we are looking to see how much they constrict, how fast they constrict, does the eye stay constricted for more than 2 seconds, does the eye exhibit any difficulty with dilating, etc.

What will a neurologist do on first visit?

During your first appointment, a Neurologist will likely ask you to participate in a physical exam and neurological exam. Neurological exams are tests that measure muscle strength, sensation, reflexes, and coordination. Because of the complexity of the nervous system, you may be asked to undergo further testing.
