Electroencephalogram

An electroencephalogram (EEG) is a painless and noninvasive test that measures the electrical activity in your brain. It is commonly used by neurologists to diagnose various neurological conditions like epilepsy, head injuries, sleep disorders, and brain tumors. During the test, electrodes are placed on your scalp to detect the brain's electrical signals.

The EEG provides continuous recordings of brain activity over time, helping identify any abnormal patterns that may indicate underlying issues. A skilled neurologist interprets the results, looking for specific patterns associated with different disorders. Additionally, it can be used to monitor brain activity during surgeries or assess the effects of medications.

While the EEG is a valuable tool in diagnosing and managing neurological conditions, it is important to remember that it alone may not provide a definitive diagnosis. Additional tests and evaluations might be necessary for a comprehensive assessment.
