Evaluating and diagnosing nervous system problems can be complex. Many of the same symptoms occur in different ways among the different disorders. And, many disorders don't have clear causes, markers, or tests. Neurological tests to evaluate children may include:
What happens during a neurological exam?
During a neurological exam, the healthcare provider will test the functioning of the nervous system. The nervous system is very complex and controls many parts of the body. The nervous system consists of the brain, spinal cord, 12 nerves that come from the brain, and the nerves that come from the spinal cord.
What tests are used to diagnose nerve disorders?
Electrodiagnostic tests. These include electromyography and nerve conduction velocity. These studies evaluate and diagnose disorders of the nerves, muscles and motor neurons. Electrodes are inserted into the muscle, or placed on the skin overlying a nerve, muscle, or muscle group, and electrical activity and muscle response are recorded.
What is included in a nervous system exam?
The nervous system consists of the brain, the spinal cord, and the nerves from these areas. There are many aspects of this exam, including an assessment of motor and sensory skills, balance and coordination, mental status (the patient's level of awareness and interaction with the environment), reflexes, and functioning of the nerves.
How do I get my nervous system checked?
A neurological exam, also called a neuro exam, is an evaluation of a person's nervous system that can be done in the healthcare provider's office. It may be done with instruments, such as lights and reflex hammers. It usually does not cause any pain to the patient.
How does a doctor check your nerves?
Electromyography (EMG) and nerve conduction studies are tests that measure the electrical activity of muscles and nerves. Nerves send out electrical signals to make your muscles react in certain ways. As your muscles react, they give off these signals, which can then be measured.

How are nervous system diseases diagnosed?
Along with blood and urine tests, tests done to diagnose nervous system diseases may include: Computed tomography (CT scan) Lumbar puncture (spinal tap) to check for infection of the spinal cord and brain, or to measure the pressure of the cerebro-spinal fluid (CSF)
Is nerve conduction test painful?
As the nerve is stimulated, you will experience a brief electrical shock. This may feel uncomfortable, but it usually isn't painful. The entire procedure usually takes about 20-30 minutes to complete. In some cases, nerves may be tested in multiple locations, which can make the procedure take slightly longer.
What test shows nerve damage?
A nerve conduction velocity (NCV) test — also called a nerve conduction study (NCS) — measures how fast an electrical impulse moves through your nerve. NCV can identify nerve damage. During the test, your nerve is stimulated, usually with electrode patches attached to your skin.
What are the first signs of nerve damage?

What happens if your nervous system is damaged?
The nervous system is fragile. It can be damaged, and it heals with great difficulty, if at all. This affects the brain's ability to communicate with your muscles and sensory organs. Nervous system injuries can be painful, and cause weakness, tingling, numbness and even changes in blood circulation.
What does nerve damage feel like?
Nerve pain often feels like a shooting, stabbing or burning sensation. Sometimes it can be as sharp and sudden as an electric shock. People with neuropathic pain are often very sensitive to touch or cold and can experience pain as a result of stimuli that would not normally be painful, such as brushing the skin.

A variety of blood tests may be performed to determine the cause of nerve damage. These tests may look for high blood glucose levels, diabetes onset, vitamin deficiencies, etc.
Is an EMG test painful?
Is an EMG test painful? EMG testing may result in some discomfort, but it is usually well tolerated without any need for pain medication.
How does a neurologist check for nerve damage?
By measuring the electrical activity they are able to determine if there is nerve damage, the extent of the damage and potentially the cause of the damage. Frequently the neurologist will recommend common, noninvasive neurological evaluations such as electromyography (EMG) and nerve conduction velocity (NCV) testing.
What is done during a neurological exam?
During a neurological exam, the healthcare provider will test the functioning of the nervous system. The nervous system is very complex and controls many parts of the body. The nervous system consists of the brain, spinal cord, 12 nerves that come from the brain, and the nerves that come from the spinal cord. The circulation to the brain, arising from the arteries in the neck, is also frequently examined. In infants and younger children, a neurological exam includes the measurement of the head circumference. The following is an overview of some of the areas that may be tested and evaluated during a neurological exam:
Why is a neurological exam done?
A complete and thorough evaluation of a person's nervous system is important if there is any reason to think there may be an underlying problem, or during a complete physical. Damage to the nervous system can cause problems in daily functioning. Early identification may help to find the cause and decrease long-term complications. A complete neurological exam may be done:
What is neurology exam?
A neurological exam, also called a neuro exam, is an evaluation of a person's nervous system that can be done in the healthcare provider's office.

How to assess mental status?
Mental status (the patient's level of awareness and interaction with the environment) may be assessed by conversing with the patient and establishing his or her awareness of person, place, and time. The person will also be observed for clear speech and making sense while talking. This is usually done by the patient's healthcare provider just by observing the patient during normal interactions.

What is the name of the test that measures the activity of the brain?
This computer-based imaging test provides a picture of the brain's activity rather than its structure by measuring levels of an injected substance with a tracer molecule, most often glucose. Arteriogram (also called angiogram). This test provides an image of arteries and veins going to and through the brain.

How to tell a child to go to the hospital?
School-aged children have good imaginations. If you don't tell them the truth, they may imagine something much worse than the actual test. The day of the test, tell your child that they will be going to the hospital to have some pictures taken. Tell them that the pictures will help the doctor decide how to make them better. Use simple words. Be honest. Try to tell your child exactly what will happen. If your child's test is going to be uncomfortable, be sure to tell them it's OK to cry. When you come to the hospital, bring along a favorite book, toy, or game. Depending on the age and emotional maturity of the child, sedation, or anesthesia may be used.

Why is EMG important?
This is important because your muscles are what allow you to maintain posture. Too much or too little energy can result in challenges.
Why is thermal scan important?
Thermal Scanning: A thermal scan is completed to check for temperature variation along the spine. This is important because the same system that controls your ability to regulate temperature- the autonomic nervous system- also controls the automatic function of your organs, glands, and vessels. This scan is able to assess where stress is building up and how it affects these internal structures.
