An electroencephalogram (EEG) is a test used to find problems related to electrical activity of the brain.
An EEG tracks and records brain wave patterns. Small metal discs with thin wires (electrodes) are placed on the scalp, and then send signals to a computer to record the results. Normal electrical activity in the brain makes a recognizable pattern. Through an EEG, doctors can look for abnormal patterns that indicate seizures and other problems.
Most EEGs are done to diagnose and monitor seizure disorders. EEGs also can identify causes of other problems, such as sleep disorders and changes in behavior. They’re sometimes used to evaluate brain activity after a severe head injury.
If a regular EEG is ordered the recording will last approximately 20 minutes after being hooked up.
If an EXTENDED EEG is ordered the recording will last approximately 1 hour after being hooked up.
If a 24 Hour EEG is ordered you will wear a recorder home and come back 24 hours later .
Vestibular Nystagmogram (VNG) is a test that measures a type of involuntary eye movement called nystagmus. These movements can be slow or fast, steady or jerky. Nystagmus causes your eyes to move from side to side or up and down, or both. It happens when the brain gets conflicting messages from your eyes and the balance system in the inner ear. These conflicting messages can cause dizziness.
You can briefly get nystagmus when you move your head a certain way or look at some types of patterns. But if you get it when you don’t move your head or if it lasts a long time, it may mean you have a disorder of the vestibular system.
Your vestibular system includes organs, nerves, and structures that are in your inner ear. It is your body’s main center of balance. The vestibular system works together with your eyes, sense of touch, and brain. Your brain communicates with the different systems in your body to control your balance.
