An electroencephalogram, otherwise known as an EEG, is a non-invasive test used to measure the brain’s electrical activity. Neurologists use small, flat, metal electrodes on the scalp to detect the electrical impulses that your brain produces during certain stimuli. At Hattiesburg Clinic, we can perform EEGs at the clinic to give a real-time comprehensive understanding of your brain activity and functionality.
An EEG measures brainwave patterns and electrical activity across different areas of your brain. We categorize these brain wave types into alpha, beta, theta and delta waves. Any changes or irregularities in these patterns may signal neurological issues or disorders. EEGs are useful in diagnosing and categorizing seizure types, sleep disorders, brain disorders such as encephalitis, dementia or Alzheimer’s disease, or brain activity after a traumatic event such as a stroke, injury or infection.
During an EEG you will be seated or lying in a comfortable position. A technician will place the electrodes on your scalp using a conductive gel. Once the test is started you may be asked to perform certain tasks, like opening and closing your eyes, looking at a flashing light or changing your breathing patterns. For some specific conditions, you may be asked to sleep as we record brain activity. Most EEGs usually last 20 to 40 minutes, unless we are monitoring during sleep.
Preparing for your EEG is relatively simple. We advise the following steps to help you get ready:
An EEG offers valuable insights into the slowing and synchronization issues associated with dementia and Alzheimer’s disease. Key markers we often see in these patients are reduced alpha activity and increased theta activity while observing disrupted connectivity within the brain. While an EEG alone cannot diagnose Alzheimer’s disease or dementia, it is a useful tool in early detection and ongoing disease progression.
