Electroencephalogram (EEG)
An Electroencephalogram (EEG) is a non-invasive diagnostic test that records electrical activity in the brain using small electrodes placed on the scalp. It helps detect abnormalities in brain function, making it essential for diagnosing neurological conditions like epilepsy, seizures, and sleep disorders.
Make an appointmentPreparation for EEG:
-
Sleep for only 3-4 hours -
Eat breakfast on day of appointment but avoid tea/coffee
-
Wash your hair either on the day of EEG or the day before but do not apply any oil to hair or scalp
-
Wear loose, comfortable clothing
Causes for an EEG Test:
An EEG is typically recommended for:
-
Diagnosing epilepsy and seizures.
-
Evaluating unexplained episodes of fainting or confusion.
-
Assessing brain activity in sleep disorders.
-
Monitoring brain function during or after surgery or head injuries.
-
Detecting conditions like encephalitis, brain tumors, or dementia.
Symptoms Indicating the Need for an EEG:
Patients may require an EEG if they experience:
-
Recurrent seizures or unusual body movements.
-
Unexplained loss of consciousness.
-
Persistent headaches or migraines.
-
Difficulty in concentrating or memory problems.
-
Sudden behavioral changes or confusion.
Treatment:
An EEG is a diagnostic tool and does not provide treatment directly. However, it guides the following:
-
Identifying the type and cause of seizures for proper medication or therapy.
-
Planning surgical interventions, such as epilepsy surgery or tumor removal.
-
Managing neurological conditions by monitoring treatment effectiveness.
Prevention:
While an EEG itself cannot prevent neurological conditions, early diagnosis helps in:
-
Preventing complications by managing epilepsy or other disorders effectively.
-
Reducing seizure triggers through lifestyle adjustments and medications.
-
Monitoring high-risk individuals for early detection of brain activity abnormalities.
