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.

Can a neurologist detect nerve damage?

Damaged nerves can lead to various symptoms. To find out, conclusively, if your nerves are damaged, you need to see a neurologist. He or she will perform tests to determine the health of your muscles and nerves. If there is a problem, the doctor will explain the reason for the damage and its extent.
