No as such recovery time is needed and the patient can head back home as soon as the test is open. The patient will have to remove the sticky material on their head which was used to paste the electrodes. What to expect after an EEG TestĪfter the EEG test is completed, the technician present there will remove the 16-20 electrodes that were placed on the scalp of the patient. The electrodes placed are just for the purpose of recording the ongoing activity inside the brain and don’t really cause any kind of sensation.Īlso, over the years the test has become non-invasive and really safe to conduct. Over the years, with the onset of technology, it has become a really easy procedure to conduct. Make sure to have clean and washed hair the night before the test.Īlso, it has to be made sure that no cosmetic products such as gels or conditioners are used a night before the test as it may make your hair non-sticky and the electrodes may have a hard time sticking to your scalp.ĮEG tests mostly have no as such risks involved.

Continue your prescribed medication unless and until the doctor suggests you to stop.Sleeping on the night before the test should be avoided as a doctor may ask you to sleep during your test.Caffeine consumption should be avoided on the day of the test as it may hamper the test results.If performed under 24-48 hours from the last seizure, EEG proves to show abnormalities in most of the cases. The patient would have their eyes closed most of the time during the procedure. Once electrodes are placed on the scalp and the whole setup is connected to a computer and ready to go, the process usually takes around an hour. But these all procedures are really health friendly and don’t cause any harm. These waves are further studied by a doctor who studies these waves to distinguish and diagnose whether the patient has any disorders or not.ĭuring the process of EEG test, the technician or the doctor may tell the patient to close or open eyes repeatedly or even put flickering lights in front of the patient to stimulate the senses.The recordings are then projected on a computer in the form of waves.The electrodes monitor the electric frequency from neurons and cells inside the brain.The electrodes are connected to wires which are further connected to a computer.These electrodes are then placed all over the head so that identical information is collected from all over the scalp.These electrodes themselves are placed inside tiny elastic caps.The process starts with the placement of tiny electrodes on the scalp of the head.In fact, it is a simple test and doesn’t involve any risks The process of electro-encephalo-graphy (encephalon-brain) isn’t as complex as the term itself. It is basically the control center of the human body. Our brain controls our thinking, our thoughts, our everyday actions, and processes. Our brain is constantly active and sending electrical signals 24/7 even when we are asleep and dreaming. Our brain basically serves 5 main functions – The human brain along with the spinal cord makes up the whole nervous system. The human brain is indeed one of the most complex organs of the human system. Encephalitis (Inflammation of the brain)ĮEG is a diagnosis method and does not cure the problem.Some disorder for which can be detected are: These are helpful to diagnose health problems related to our brain. Any result with a frequency of 8 Hz and higher comes under normal outcomes any EEG Test.Īn EEG test measures electrical movement and pulses. These signals are later measured through an EEG test. Synapses are the junction through which electrical signals pass from one nerve cell to another. These neurons interact with each other and are connected to each other via synapses. Just like our body is made up of millions of cells, similarly, our brain is made up of millions of neurons. We’ll get in detail with each one of these queries but first, let’s understand the term EEG in certain detail. Is this test good for health or can it cause any kind of problems to health?.How are the electrical signals measured inside our brain and what is the process?.

Now all of us may have few similar queries? The more the irregularities in the waves, the greater the chance a person has some kind of brain disorder. Through the process of EEG Test, doctor measure these Electrical Pulses. The synchronized activities of these neurons create an electric field inside the brain. Our brain consists of billions of neurons. In the simplest language, an EEG test or electroencephalography is the test or a method used to measure Electrical Signals inside our brain.
