EEGs Are Safe
One of the biggest advantages of EEGs is that they are completely safe for most people.
The most common exception to this is in the case of those with a seizure disorder, but even then, the risk is only slight. Although rare, it is possible for the deep breathing and flashing lights associated with the EEG to trigger a seizure.
Even if someone has a seizure disorder, this risk is rare enough to conduct an EEG. The only caveat is that your doctor will likely have extra medical staff on hand in case you do experience a seizure.
Preparation Is Simple
Another benefit of an EEG test is that the preparation is very simple. The most challenging instruction is to not have anything with caffeine in it for about eight hours before the test.
You will also have to wash your hair at night before the test and not use any styling products or leave-in conditioner. If you have extensions with glue on them, you will also have to remove them.
Other than those two things, the preparation is straightforward. You can normally eat, as low blood sugar can lead to abnormal results. In the case of sleeping EEGs, you may also have additional sleep-related instructions. Of course, you will also have to tell your doctor about any medications and supplements you are taking.
They Are Relatively Fast Outpatient Tests
A traumatic brain injury EEG is a relatively short outpatient procedure, making it easier to schedule. The test typically takes approximately 45 minutes and two hours.
You Can Drive Home After the Test
In nearly every case, you will be able to drive home following a daytime EEG test. The only exceptions will be if you are experiencing active seizures or if the doctor recommends against it. If your EEG was overnight, you should have someone drive you.
It Can Provide Early Detection of TBIs
Because of all of the above benefits, EEGs can offer an incredibly useful early diagnostic tool to help assess TBIs. This can be especially helpful to tell if more invasive tests are necessary. Some research even praises the ability of EEGs to offer a more portable testing method for athletes and those in the military. Of course, this early detection is not just limited to those groups. It can apply to anyone who experiences a TBI.
