A neurological examination comprises several tests to measure the function of the patient's nervous system, and physical and mental alertness. The tests may focus on memory, hearing and vision. Your doctor will also test your muscle functions -- such as reflexes, strength and coordination.
If responses to the exam are not normal, your neurologist or neurosurgeon will then order diagnostic procedures, most likely an MRI or CT scan.
Doctors use the diagnostic information to classify the tumor from the least aggressive (benign) to the most aggressive (malignant).
