Delta waves indicate the deepest levels of relaxation and restorative sleep. This is why doctors also call Stage 3 of sleep as Delta Wave Sleep. In fact, the stages of sleep were first discovered via the use of EEG. Different brain activities correspond to different stages of sleep. The EEG readings can give a doctor a clearer picture of a patient’s sleep patterns. This is a non-invasive test and is safe even for children. While connected to an EEG, the sleep specialist monitors the stages of sleep of a patient. During the said test, a patient stays overnight in a medical facility. Doctors use EEG as part of a sleep study or polysomnography. On the other hand, a person with lesions on the brain may show unusually slow EEG waves.Īn EEG is also useful in diagnosing narcolepsy and insomnia. For example, rapid spiking waves on an EEG may indicate the presence of epilepsy. They are also printable so a patient can bring it to a healthcare provider for interpretation.Īn EEG is useful in evaluating several types of brain disorders. These charges appear as a graph viewed on a computer screen. The electrodes then detect tiny electrical charges produced from the activity of the brain cells. These electrodes have wires connected to a computer. This test uses electrodes made of small metal discs that get pasted on the scalp of the patient. ![]() Read our full medical disclaimer.Īn Electroencephalography (EEG) is a test that can detect abnormalities in the brain waves or the electrical activity of the brain.
