This paper primarily focuses on EEG signals and. These signals are generally categorized as delta, theta, alpha, beta and gamma based on signal frequencies ranges from 0.1 Hz to more than 100 Hz. Results of the EEG may be available several hours after the test. Electroencephalography (EEG) is an efficient modality which helps to acquire brain signals corresponds to various states from the scalp surface area. The results of EEG neurofeedback often referred to as biofeedback show how the brain. The process involves the utilization of data gleaned from real-time results given by an electroencephalography machine. Proper procedures call for the patient to remain still and relaxed, with eyes closed even though he or she may be awake. EEG neurofeedback is a measurement of brain activity used as a diagnostic tool, usually with the aim of controlling brain function. At the doctor’s office or hospital room, the patient may lie in a bed or recline in a chair with up to 25 electrodes placed on the head. For instance, a patient may be instructed to reduce sleep the night before if she is required to sleep during the EEG. Instructions may be given regarding sleep schedule that are specific to each patient. Fasting is prohibited before the test because low blood sugar can skew the results. The doctor may request that the patient stops taking medications or avoids any caffeinated foods and beverages for several hours. The patient should avoid using conditioners or other hair products because they may interfere with test results. Hair should be washed with just shampoo the night before the exam, as electrodes would be placed on the scalp.

This may be an option for some people with uncontrolled epilepsy. That is why some long-term EEG tests may be done at home. 6 Seizure monitoring at homeĪs with any hospital stay, an epilepsy monitoring unit can be expensive in both money and time. Audio allows them to listen as you describe what you feel before or during a seizure.Īfter leaving the unit, you may need to stay in the hospital another day or 2 to make sure you are safe to go home. Video allows doctors to see any physical changes you may not be able to explain yourself. This is done so the EEG can record what is happening in your brain. Or, they may expose to you another trigger such as fast breathing, flashing lights, or lack of sleep. 6ĭuring your stay in the unit, your doctors may try to trigger seizures by changing your anti-seizure medicines.
Most people also bring a laptop, smartphone, games, puzzles, or craft supplies to pass the time. 6Ī nurse, an EEG technician, and doctors will monitor your brain activity 24 hours a day from a nearby room. An average stay is 3 to 7 days, but it may be less or more. These electrodes will connect to the EEG monitor to measure your brain activity 24 hours a day. The cap is placed on your head, like any other hat, and is connected to the computer with wires. 6Īfter you check in, the team will attach dozens of electrodes to your head. An EEG (Electroencephalography) is a simple fabric cap that is embedded with sensor electrodes. You may need to pack certain clothes or slowly reduce or stop some of your anti-seizure drugs before your stay. Your healthcare team will help you plan for your stay in the unit.
