What is EEG ( Electroencephalogram) ?

An EEG is a test that checks the electrical activity in your brain. Brain cells communicate with each other through electrical impulses. This test detects any problems associated with this activity. It records and tracks the patterns of brain waves. Small and flat metal discs known as electrodes are attached to your scalp with some wires. The electrodes analyse the electrical impulses in your brain and send signals to the computer that records your results. These impulses enable doctors to assess whether there are any abnormal patterns. Any irregularities detected can be a sign of brain disorder or seizures.

Why is EEG done?

An EEG can detect changes in your brain’s activity that might be a sign of a brain disorder like seizure disorder or epilepsy. It can also be useful for treating or diagnosing the following conditions.

1. Brain damage from a head injury

2. Brain tumours

3. Brain dysfunction due to condition such as encephalopathy

4. Brain inflammation (herpes encephalitis)

5. Sleep disorders

6. Brain tumours

7. Stroke

Which are the tests performed during an EEG?

The following types of tests might be performed during an EEG.

1. Sleep-deprived EEG or Sleep EEG

2. Video telemetry

3. Ambulatory EEG

4. Routine EEG

5. Invasive EEG-telemetry

What is EMG ( Electromyogram) ?

An EMG or electromyogram records the electrical activity of your muscles. When there are active muscles, they produce electrical currents. The current is proportional to the level of your muscle activity. It can detect inflammation of your muscles and abnormal dystrophy that occurs in many conditions and diseases, including nerve damage in your legs and arms. It is performed when the patient experiences muscle weakness. EMG helps to distinguish between the muscle conditions in which the problem starts in the muscle and nerve disorders that lead to muscle weakness.

Why is EMG done?

Your doctor might ask you to get an EMG test done if you experience symptoms that indicate a muscle or nerve disorder. Some of these symptoms include:

1. Numbness

2. Muscle weakness

3. Limb pain

4. Tingling

5. Muscle cramping or pain

Which are the tests performed during an EMG?

An EMG test is done in two parts

1. NCS or Nerve Conduction Study

2. NEE or Needle Electrode Examination

What is NCV ( Nerve Conduction Study ) ?

NCV is a diagnostic test used to check the ability and function of electrical conduction of the sensory and motor nerves of the human body. It determines nerve dysfunction and damage. The peripheral nerves are located outside the brain and along the spinal cord. They help you to experience your senses and control the muscles. Healthy nerves send electrical signals more rapidly and with greater strength in comparison to damaged nerves.

NCV test helps the doctor to differentiate between an injury to your nerve fibre and an injury to a protective covering surrounding your nerve. It also allows your doctor to distinguish between a condition where a nerve injury affects the muscles. From this test, the doctor can provide a proper course of treatment.

Why is an NCV done?

You can take an NCV test for the following reasons.

1. To check if you have a muscle or nerve disorder

2. To ensure optimum nerve and muscle health

3. To identify the cause behind symptoms like weakness, pain, tingling, or cramping

4. To find out the causes behind muscle disorder or weakness apart from the pain

Which are the tests performed during an NCV ?

The different types of NCV tests are:

1. Sensory

2. Motor

3. Mixed
