What is an EEG?
Dr. Ata utilizes an EEG to record electrical activity in your brain. Brain cells communicate with each other through brain waves or electrical signals. This diagnostic test is performed by placing small metal discs on your scalp (electrodes), these electrodes have wires attached to them and run to a computer. Your brain activity or electrical impulses are recorded in lines that have peak and valleys. Dr. Ata will then analyze these recording to determine if you have any abnormal patterns.
Why would I need an EEG? What types of disorders does an EEG help diagnose?
More then likely your physician has evaluated you and developed a few potential diagnoses that may be the cause of your symptoms. An EEG may be one of the diagnostic tests that will be ordered to help rule out or confirm various conditions such as:
- Epilepsy
- Brain damage from head trauma
- Brain tumor
- Stroke
- Sleep disorders
- Encephalitis
- Abnormal brain function
Are there different types of EEGs studies?
Yes, there are different types of EEG tests that are performed depending your symptoms or diagnosis. These different tests typically vary by the duration or specific length the test is performed. Also, the use of video may or may not be utilized during an EEG. A video EEG is recommended to capture what is happening the body and brain during an event. The different types of EEGs are:
- Routine EEG
- Ambulatory EEG
- Video EEG
What do the EEG results mean?
A physician trained in EEG (typically a Neurologist) like Dr. Ata will review your brain activity patterns and utilize this information in his diagnosis. If another physician ordered your EEG Dr. Ata will review your findings, provide his opinion, and send this information to your physician.
How long does an EEG test take?
A routine EEG typically lasts between 30-60 minutes. Ambulatory and video EEGs are typically done in your home and can last 1-3 days.
Is an EEG test painful? Are their any long term affects of an EEG?
No, EEG tests are pain free and carry no risks.
What happens if my EEG test is abnormal?
Unusual or uncommon patterns on an EEG do not necessarily indicate an abnormal finding unless this is paired with a clinical history and associated with a disease state or specific pathology. There are five categories that abnormal EEG findings fall into: abnormal expressions of normally occurring rhythms, inherently abnormal rhythms, certain repetitive or abnormal patterns, epileptiform abnormalities, and abnormal super architecture. Your results should be reviewed and explained in detail at a subsequent appointment. At this time your physician may ask additional questions regarding your history and symptoms, recommend lifestyle modifications, additional testing, medications, or a consultation with another specialist. At this time you can ask your physician any questions or concerns you may have regarding your abnormal EEG results.
