Neuroelectrophysiology is a specialty of neurology that studies the functioning of the brain, nerves, and muscles using electrical recording techniques. These tests help in the identification of neurological disorders, disease progression monitoring, and planning the right treatment.
Electroencephalography (EEG) is a diagnostic test that records the electrical activity of the brain using small electrodes placed on the scalp. The test is non-invasive, painless, and provides valuable information about how the brain is functioning in real time.
What it detects
The electrical activity that occurs in the brain
Abnormal brain waves associated with epilepsy, seizures, sleep disorders, and neurological illnesses.
Changes in brain function caused by infections, strokes, or trauma
When it is recommended
To examine patients with unexplained fainting or seizures
To assess sleep issues or reduced sensory function
To test patients suspected of having a brain infection, tumor, or metabolic encephalopathy
To monitor brain activity in intensive care unit patients
Procedure
Electrodes are placed on the patient’s scalp using a conductive gel.
The patient is instructed to relax and may be asked to do things like take deep breaths or look at flashing lights.
The standard duration for this procedure is thirty to sixty minutes.
It is non-invasive and does not cause pain.
The Nerve Conduction Study (NCS) is a diagnostic test that measures how quickly and effectively electrical signals travel along your nerves. It helps doctors evaluate the health and function of peripheral nerves, which connect the brain and spinal cord to the rest of the body.
Purpose
To determine how quickly and efficiently electrical signals flow via nerves
To determine whether conditions like neuropathy, carpal tunnel syndrome, or nerve trauma have damaged the nerves
Procedure
Small electrodes are placed on the skin’s surface to cover the nerves.
The nerve is stimulated with moderate electrical impulses.
The reaction is recorded to assess nerve function.
The inspection is completely risk-free, with only a faint tingling sensation.
Electromyography (EMG) is a diagnostic test that evaluates the electrical activity of muscles and the nerves controlling them. It helps doctors understand whether muscle weakness or abnormal movements are due to muscle disorders, nerve damage, or problems at the junction between nerves and muscles.
Purpose
To measure the electrical activity of muscles both during rest and during contraction
To diagnose muscle disorders, nerve root compression, and neuromuscular junction issues
Procedure
A needle catheter is inserted into the muscle.
The person receiving treatment is instructed to contract and then relax the muscle.
The procedure entails recording and analyzing electrical impulses.
The needle may cause temporary discomfort; yet, the test is widely accepted.
Polysomnography, commonly known as a sleep study, is a comprehensive test that records various body functions during sleep. It helps doctors diagnose sleep-related disorders by monitoring brain activity, breathing, oxygen levels, heart rhythm, and muscle movements throughout the night.
What it detects
It monitors brain activity during sleep, as well as breathing, oxygen levels, heart rate, and muscular movement.
It helps detect various sleep disorders, including narcolepsy, sleep apnea, insomnia, and restless leg syndrome.
Procedure
The procedure is carried out in a sleep unit for the entire night.
Sensors are attached to the limbs, chest, or scalp.
Continuous monitoring is performed on both breathing patterns and oxygen levels.
The procedure is painless and allows for natural sleep to occur in a supervised environment.
Before receiving an EEG, ensure your hair is dry and free of oils and gels.
Caffeine and other stimulants should be avoided before doing EEG or sleep tests.
For EMG and NCS, dress comfortably and loosely.
It is critical to inform your doctor about any medications you are taking, as some medications may affect the test results.
To ensure accurate recordings, acquire enough sleep before the polysomnography.
The reports are produced by neuroelectrophysiology experts.
We correlate the data with clinical findings to arrive at an accurate diagnosis.
A thorough interpretation guides treatment plans, rehabilitation, and surgical decisions.
Reports are often available within 24 to 48 hours, depending on the exam.
HCG Hospitals houses cutting-edge technology that enables specialists to provide the best quality care for patients in need of comprehensive neurophysiological support. Highly skilled experts staff our neuro ICU, dedicated to providing compassionate care and support to critically ill patients.
Our specialists at HCG employ a patient-centered approach, wherein we place a high value on open communication of outcomes, allowing patients and their families to participate actively in the process of receiving timely medical care.
An electroencephalogram (EEG) is required in cases of seizures, epilepsy, sleep disturbances, or unexplained loss of consciousness since it records brain activity.
The NCS evaluates the ability of nerves to transport electrical signals. Electromyography (EMG) examines muscle activity to detect problems with the nerve roots or muscles.
Together, they provide a full picture of nerve and muscle function.
EEG and NCS are both painless, with the NCS producing only a little tingling sensation.
Electromyography tracing (EMG) is performed with a tiny needle, which may cause discomfort but is usually well tolerated.
It is a study that monitors how the brain and body work while the subject sleeps. This procedure is used to diagnose sleep disorders such as sleep apnea, insomnia, narcolepsy, and others.
Reports are often available within 24 to 48 hours, depending on the extent of the examination and evaluation completed by the specialist.
