Diagnostic tests and procedures are vital tools that help physicians confirm or rule out the presence of a neurological disorder or other medical condition. A century ago, the only way to make a positive diagnosis for many neurological disorders was by performing an autopsy after a patient had died. But decades of basic research into the characteristics of disease, and the development of techniques that allow scientists to see inside the living brain and monitor nervous system activity as it occurs, have given doctors powerful and accurate tools to diagnose disease and to test how well a particular therapy may be working.
There are two general types of neurodiagnostic tools:
1. Electrical impulse detection : which examine the electrical impulses of the body's nervous system to determine if the system's functioning.
2. Imaging or Scans : which show pictures of the anatomy and /or biochemistry of the body.
