I Can’t Get a Handle on My Migraines — Can You Help?
Yes! We can help with the pain, nausea, sensitivity to light and sound, and other symptoms that are common with migraines. Our treatments also focus on preventing these painfully common headaches.
Who Should Get an EEG?
Used by the medical world since 1929, with many improvements since its inception, an electroencephalography (EEG) traces and records electrical pulses produced by the brain.
Once recorded and interpreted by a computer, these signals are represented as wavy lines with peaks and valleys. An irregularity in brainwave patterns can signal a brain disorder.
Board-certified neurologist Dr. Andrew Lerman and his team at Gables Neurology in Miami, Florida, offer some of the most advanced neurological care available for issues such as chronic migraines, seizure disorder, and dementia.
Dr. Lerman also offers a full range of electrodiagnostic testing and medicine, including EEG. Here’s why Dr. Lerman may recommend an EEG and what you can expect during the test.
Why would I need an EEG?
EEG tests are helpful for both clinical and research purposes. They can aid in the diagnosis and management of various neurological conditions, such as:
Epilepsy
An EEG is commonly used to detect and evaluate epilepsy, a neurological disorder characterized by recurrent seizures. The test helps Dr. Lerman identify abnormal brainwave patterns associated with seizures and provides essential information for determining the appropriate treatment approach.
Sleep disorders
An EEG is instrumental in studying sleep patterns and diagnosing sleep disorders like sleep apnea, insomnia, narcolepsy, and parasomnias. It allows specialists to monitor brainwave activity during different stages of sleep and assess any irregularities.
Brain injury
An EEG helps assess brain function following a traumatic brain injury. It can detect abnormalities in brainwave activity caused by these conditions, aiding diagnosis and monitoring treatment effectiveness.
Brain tumors and strokes
EEG tests can be utilized in the evaluation of brain tumors or strokes. They can help locate the affected areas of your brain, determine the severity of the condition, and guide treatment decisions.
Cognitive disorders
An EEG is sometimes used to assess cognitive disorders such as dementia and Alzheimer's. It can provide insights into brain activity and help distinguish between different types of cognitive impairment.
What to expect during an EEG
Dr. Lerman provides specific instructions about preparing for an EEG and what you can expect during the test.
However, here's what usually happens during an EEG:
Preparation
On your test day, you may be asked to wash your hair to remove any oils or hair products that might interfere with electrode placement. In some cases, electrodes may be placed directly on your scalp, while in others, a snug-fitting cap with built-in electrodes is used.
Electrode placement
An EEG technician measures your head and uses gel to place electrodes. The electrodes are connected to an amplifier and nearby recording system, which capture and record your brain's electrical activity.
Recording
During the recording phase, you’re comfortably seated or lying down in a quiet room. EEG recording typically lasts between 20 minutes to an hour, depending on the purpose of the test.
Dr. Lerman may ask you to close your eyes and relax or perform specific tasks, such as deep breathing, to elicit specific brain responses. He might also consider other actions during your test, such as exposure to bright or flashing lights to monitor for seizure triggers.
What happens after the EEG?
Sometimes, Dr. Lerman asks you to wait as he interprets your EEG results. Otherwise, you may be able to resume your regular activities immediately after your procedure.
In either case, Dr. Lerman carefully analyzes the recorded data and studies your brainwave patterns to identify abnormalities. He then develops a treatment strategy that may include further evaluation, medication, or ongoing treatment for the diagnosed brain disorder.
