Electroencephalogram (EEG)

Electroencephalogram (EEG) is a diagnostic test used to evaluate the electrical activity of the brain. The test is conducted by placing small electrodes on the scalp that measure the electrical signals produced by the brain. These signals are then recorded and analysed by a machine to provide

information about the brain’s functioning.

Test Preparation:
There is typically no special preparation required for an EEG. However, patients may be asked to avoid caffeine or certain medications prior to the test. They may also be asked to wash their hair beforehand and avoid using hair products, as these can interfere with the electrode placement.

Common Symptoms for ordering the test:

An EEG may be ordered for a variety of reasons, such as:

• Seizures or seizure
• disorders
• Head injuries
• Sleep disorders
• Memory problems or confusion
• Dizziness or vertigo
• Brain tumors or infections
• Monitoring brain activity during surgery

Time taken for the test:
The test itself typically takes between 30 minutes to an hour to complete. However, in some cases, the test may be prolonged for several hours or even days if a patient is being monitored for seizures or other conditions.

Results Interpretations:
The results of an EEG are interpreted by a trained healthcare professional, such as a neurologist. The results may show abnormalities in brain activity, such as spikes, slow waves, or patterns consistent with seizures or other conditions. In some cases, the results may be inconclusive or require further testing. The healthcare professional will use the results of the EEG, along with other medical information and test results, to make a diagnosis and develop a treatment plan for the patient.
