What is the EEG Test?
Electroencephalography (EEG) or sleep study test is a test that uses metal disks called electrodes placed on the scalp to record electrical activity in the brain. It is primarily used to test for epilepsy and diseases affecting the brain.
The electrodes detect electrical impulses used by brain cells to communicate with each other. These impulses are captured by the electrodes on a computer system, where they appear as a series of curved lines (known as a trace), allowing scientists to read a picture of brain activity.
For almost a century, EEG has been used and refined, bringing many discoveries to neurology and psychiatry, and helping physicians diagnose and treat their patients.
Advantages of Sleep study test at home
In the broadest sense, EEG studies or monitors brain activity. It has various medical applications, such as assisting in studying sleep disorders, seizure disorders, psychiatric conditions, and other conditions.
It is usually used to diagnose brain diseases and monitor how they affect brain activity. It is often used as a tool to diagnose epilepsy and other seizure activity factors and can help monitor it over time to assess the effectiveness of certain treatments. There is a reason why many neurologists and other physicians rely on EEG tests. They are accurate, safe, relatively inexpensive, and non-invasive.
History of the EEG Test
Electroencephalography is almost a century old. In 1929, the German psychiatrist Hans Berger published his essay On the Electroencephalogram of Man. The essay shows a method of recording electrical activity from the brain. He did this with a roughly built-in EEG machine, which creates some of the characteristic wave patterns in the lines that modern machines do today.
Why are EEG Tests Performed?
If a person exhibits behaviors that can be caused due to their brain activity – such as a seizure – it is important to ensure that the exact cause is known. EEG tests are used to check the brain’s electrical activity with the help of neurologists, which allows them to detect abnormal characteristics of electrical impulses.
The brain activity monitor is used to identify any irregularities by analyzing patterns and waveforms.
Why Do Doctors Recommend EEG?
If people have seizures or other events caused by a brain abnormality, EEG tests are usually one of the first recommendations. It is the primary diagnostic tool used when a doctor suspects epilepsy.
EEG can also be used to confirm that events are not caused by a brain abnormality but by the heart. Test results can help physicians decide what steps to take in a treatment plan or whether additional tests are needed.
How Does the EEG Work?
So what do the small waves on the screen have to do with precisely what is going on in the brain? It all starts with the billions of cells that are in the human brain. About half of these cells are neurons, while the other half help speeds up the activity of the neurons.
This is done through a series of gateways between neurons called synapses, which are responsible for inhibiting or stimulating nerve activity.
When Should You Undergo a Sleep Study Test?
If you experience an event related to abnormal brain activity, such as a seizure, your doctor may recommend an EEG to determine the cause. This is often the case when there is reason to believe that you may have a condition such as epilepsy, trauma, or other brain diseases.
If you have recently had a seizure, panic attack, severe migraine, or have recently disappeared, you should consult a doctor and get his / her expert opinion.
Eventually, your doctor may or may not send you for an EEG test, depending on what information you need about your condition.
How is Star Home Care Diagnostic Center’s EEG Test at Home Facilities are Different from Others?
At Star Home Care Diagnostic center, we supply our own EEG-ECG video. The test is:
· At home – the test is performed at home without a hospital visit
· Long-term – the length of the test can vary between 3 and 10 days, depending on what your doctor recommends
· Outpatient – you carry a portable EEG-ECG device, and you can move freely around your house
Extending the tracking time or the monitoring by 3-10 days gives you a better chance of catching the event than will happen. Being at home with the possibility of free movement exposes you to your natural environment and possible causes of the phenomenon.
Our EEG test at home is performed in combination with an electrocardiogram (ECG) to let your doctor know if the events you are experiencing come from your brain or heart or both. Heart problems are sometimes confused with brain conditions because the symptoms may look the same. That’s why the ECG is so important that we understand what’s really going on. In many people, the diagnosis changes after ECG results show that they do not have epilepsy.
