EEG or Electroencephalogram scan

Neuro treatment in Mysore

An EEG or Electroencephalography scan is a type of medical test used to measure and record electrical activity in the brain. It works by using a device that records the brain's electrical activity through small electrodes attached to the scalp. These electrodes are connected to a computer, which then processes the data and produces a graph, known as an EEG. The EEG graph can diagnose various neurological conditions, such as epilepsy and sleep disorders. EEG scans are noninvasive and are generally considered safe. Patients are asked to relax, stay still, and often close their eyes during the procedure. The electrodes record the brain's electrical activity, which is then displayed on the computer. The EEG can diagnose various neurological conditions, such as epilepsy and sleep disorders.


A pre-procedure for an EEG scan involves a series of steps to ensure the scan is successful and minimise potential risks. Before the scan, a patient will typically be asked to complete a medical history form to identify any underlying medical conditions that may affect the scan results. The patient will also be asked to remove any metal objects that could interfere with the readings, such as jewellery or hair accessories. The patient may be asked to wear a hospital gown, and their hair may need to be washed with a special shampoo to reduce natural oils.


  • The procedure typically begins with the patient lying down and having their head shaved if necessary. This allows the sensors to be glued to the scalp and connected to an EEG machine. The patient is then asked to remain still and follow instructions given by the technician.

  • The EEG machine will then measure the electrical activity in the patient’s brain and display the results on a monitor. During the procedure, the patient may be asked to perform different tasks such as counting, breathing, and focusing on a single object to measure brain activity further.

  • The procedure typically takes about an hour, and the patient will then be asked to remove the sensors and leave the room.

  • The results of the EEG scan are then reviewed by a doctor and interpreted to diagnose any neurological conditions or disorders. Depending on the results, the doctor may suggest further tests or treatments.


  • The post-procedure for an EEG scan at neuro hospital in Mysore is a set of steps medical professionals take to ensure the patient’s safety and comfort after the procedure. This includes monitoring the patient’s vital signs, ensuring they are stable, and providing instructions on caring for the patient’s scalp and electrodes. 

  • Immediately after the procedure, the patient should remain still and quiet to allow the EEG electrodes to stay in place and prevent any damage. The patient should also be kept warm and comfortable and provided with blankets or a pillow if needed. 

  • The medical professional will then remove the EEG electrodes and the paste used to attach them. This paste can be wiped away using a cloth and warm water. It is essential to avoid using oil-based products, as this can damage the EEG electrodes. The patient’s scalp should be gently washed with a mild soap and water solution. 

  • The medical professional will assess the patient’s scalp for any irritation or redness and provide treatment if necessary. The patient should also be informed about any side effects of the procedure, such as headaches and nausea. 

  • Finally, the patient should be given follow-up instructions, such as scheduling a follow-up appointment or contacting the doctor if any symptoms worsen. The patient should also be reminded to take any medications as prescribed by the doctor.
