What is an EEG?
An EEG (electroencephalogram) is a test that measures and records electrical activity in the brain.
What are the symptoms that might lead to an EEG?
An EEG might be done if someone is experiencing seizures, dizziness, headaches, confusion, or other neurological symptoms.
What can an EEG help diagnose?
An EEG can help diagnose conditions such as epilepsy, sleep disorders, brain tumors, and brain damage.
What does an EEG show in someone with epilepsy?
An EEG can reveal abnormal electrical activity in the brain that is associated with seizures or epilepsy.
What is the price of an EEG test?
The cost of an EEG can vary depending on where it is done, but it can range from several hundred to several thousand dollars.
What is the process of getting an EEG?
During an EEG, electrodes are placed on the scalp and connected to a machine that records the electrical activity in the brain while the person is at rest or in response to certain stimuli.
What is deep learning for EEG classification tasks?
Deep learning is a type of artificial intelligence that uses neural networks to identify patterns in EEG data and classify them into different categories.
What are some common findings on EEGs?
Normal EEG findings include alpha, beta, theta, and delta waves. Abnormal findings can include spikes, sharp waves, or slowing of certain waves.
What are some factors that can affect EEG results?
Factors that can affect EEG results include medications, sleep deprivation, dehydration, and alcohol or drug use.
Can an EEG diagnose Alzheimer's disease?
An EEG cannot diagnose Alzheimer's disease specifically, but it can help identify abnormalities in brain wave patterns that may be associated with the disease or other neurological conditions.
What is the difference between an EEG and an MRI?
An EEG records the electrical activity in the brain, while an MRI uses magnetic fields to create detailed images of the brain's structure.
Can an EEG be done on a sleeping person?
Yes, an EEG can be done on a sleeping person to evaluate sleep disorders or identify abnormal brain activity during sleep.
What is a sleep-deprived EEG?
A sleep-deprived EEG is an EEG that is done after the person has been intentionally deprived of sleep, which can make abnormal electrical patterns more visible.
What kind of information can be obtained from an EEG?
An EEG can provide information about brain activity and can help diagnose certain neurological conditions, monitor brain function during surgery, and evaluate changes in brain function over time.
Can an EEG tell how intelligent someone is?
No, an EEG cannot measure intelligence or cognitive abilities.
What is an ambulatory EEG?
An ambulatory EEG is an EEG that is done while the person goes about their daily activities, typically over a period of 24 to 48 hours.
Can an EEG predict the onset of a seizure?
Some newer EEG technologies may be able to detect changes in brain activity that signal the onset of a seizure and provide warning to the person or their caregivers.
What is the difference between a routine EEG and a video EEG?
A routine EEG records brain activity while the person is at rest, while a video EEG adds video recording to capture any behavioral or physical changes during the EEG recording that may be associated with neurological conditions like seizures.
What kinds of treatment might be recommended based on an EEG?
Treatment for neurological conditions revealed by an EEG might include medications, surgery, lifestyle modifications, or other interventions to manage symptoms or prevent seizures.
What is a prolonged EEG?
A prolonged EEG is an EEG that is recorded continuously over a period of days or weeks to monitor changes in brain activity over time.
Can an EEG be used to diagnose a concussion?
An EEG is not typically used to diagnose a concussion, but it may be used to evaluate any associated neurological symptoms or complications.
What does an electroencephalogram measure quizlet?
An electroencephalogram (EEG) measures the electrical activity of the brain.
What are some possible side effects or risks of an EEG?
An EEG is generally considered safe and does not usually have side effects or risks, but some people may experience discomfort or itching from the electrodes or have an allergic reaction to the gel used to attach them.
Can a person with a pacemaker or other medical device have an EEG?
In general, medical devices like pacemakers do not interfere with or make it unsafe to have an EEG.
What are some limitations of an EEG?
EEGs can only detect electrical activity on the surface of the brain, so they may not be able to reveal activity deeper in the brain or provide a complete picture of brain function.
How is an EEG used in sleep medicine?
An EEG may be used to evaluate sleep disorders such as sleep apnea or to measure brain activity during different stages of sleep.
What is the youngest age at which an EEG can be done?
EEGs can be done on infants, but the technique may need to be modified to accommodate their smaller heads and movements.
Can an EEG detect the presence of a tumor in the brain?
An EEG cannot detect the presence of a tumor specifically, but it may be used to identify abnormal electrical activity that is associated with certain types of tumors or other neurological conditions.
What is the potential for future research using EEG technology?
EEG technology is constantly being improved and refined, and researchers are exploring new applications in areas like brain-computer interfaces, neurofeedback, and brain training.
