What is Digital Electroencephalography?
- It’s a test for brain activity
- It can detect abnormalities in the brain
- It’s safe and painless
- It can have varying results
The brain weighs around 3 pounds. Even with this weight, it stands to be one of the most complicated organs in the human body. The brain is also the center for many bodily functions and electrical activity. An electroencephalogram is used to monitor the electrical activity in your brain. Have you experienced head injuries, memory problems, and other related disorders? A digital EEG in Las Piñas can detect the root of the problem and help your doctor find the best solution. Here’s how it works and why you need it.
It’s A Test For Brain Activity
A digital EEG test is done to monitor and evaluate electrical pulses in the brain. The brain cells function by communicating with each other through electrical activity. Having an EEG will detect any problems associated with your brain activity.
This procedure records brain wave patterns with the use of electrodes. These electrodes are strapped to the scalp with wires. The electrodes then analyze the electrical impulses and simultaneously send signals to the computer. The computer will then record and analyze the results.
These records are similar to waves. It has significant peaks depending on your brain activity. The study of these lines is left to your doctor. Any signs of abnormalities can be detected through these records. If there are any, it can be a sign of further brain trauma.
It Can Detect Abnormalities In The Brain
Digital EEGs can help detect abnormalities in the brain. These abnormalities can be associated with brain disorders, which is why it is important to be aware of them early on. Here are some abnormalities the digital EEG procedure can detect:
Epilepsy is a disorder that can cause recurrent seizures. Seizures are said to be a rush of electrical activity in the brain. These seizures can either affect the brain as a whole or only certain parts of it. Mild seizures can be a challenge to detect, unlike stronger ones. Stronger seizures tend to cause spasms in the muscles. These seizures can last up to several minutes depending on the severity.
Brain tumors are a host of abnormal cells within the brain. The growth of these tumors in your skull can cause a lot of problems, especially if the tumors are cancerous. Brain tumors can cause pressure inside the skull to increase, which can lead to permanent brain damage if left untreated.
Head injuries can come in the form of mild bruises or grave trauma. The most common types of head injuries are concussions, scalp wounds, and fractures. Different treatments can be recommended depending on its severity. It is important to have your doctor assess the injury as soon as possible to determine the severity and to speed up treatment.
When a part of the brain is damaged, a person may go into a coma. The damage can be temporary or permanent. This then leads to a prolonged state of unconsciousness and unresponsiveness. Comas can be caused by injuries, strokes, tumors, alcohol abuse, and drug abuse. Digital EEGs can detect brain activity when the patient is in a coma.
It’s Safe And Painless
Digital EEGs pose no risk and are proven to be safe. Some EEGs don’t include stimuli like lights but can be added to induce and monitor abnormalities. For example, a patient with a seizure disorder needs stimuli such as flashing lights to induce the seizure. The doctor or technician performing the EEG is trained for this and can safely manage the situation once it happens.
Prior to your EEG, you must wash your hair and avoid using styling products on the day of your test. Your doctor will also instruct you to stop any medications prior to testing. Caffeinated drinks should also be avoided within an 8-hour time frame before the test.
After the procedure is over, you can return to your routine as soon as possible. However, some EEG procedures require sedatives and this can stay in your system for a while. Make sure to have a companion to take you home after the test. Avoid driving and rest properly until the medication is out of your system.
It Can Have Varying Results
Depending on the results, a neurologist will take apart and interpret your EEG results. After this, they will send it over to your doctor. You may need to schedule a follow-up appointment if abnormalities are detected.
The electrical activity appears as waves. Different frequencies of consciousness have a specific pattern that is considered normal. Patterns that move fast when you’re awake are normal. If the patterns detected by your neurologist are abnormal, you may have the following brain disorders:
- Brain Hemorrhage
- Sleep Disorder
- Decreased Brain Blood Flow
- Head Injuries
