What is an Electroencephalogram (EEG)?
An Electroencephalogram (EEG) is a non-invasive diagnostic test that records electrical activity in the brain. It is widely used to evaluate and diagnose neurological conditions by detecting abnormalities in the brain’s electrical patterns. An EEG provides crucial insights into brain function, making it an essential tool in modern neurology.
How Does an EEG Work?
The EEG measures brain activity through small electrodes placed on the scalp. These electrodes detect the brain’s electrical signals and transmit them to a computer, where they are recorded and analysed.
Recording Brain Waves: The EEG captures different types of brain waves, including alpha, beta, delta, and theta waves, each associated with specific mental states or activities.
Pattern Analysis: Abnormalities in the recorded wave patterns can help identify neurological conditions, such as epilepsy or sleep disorders.
A Video EEG combines standard EEG monitoring with video recording to correlate brain activity with physical behaviour, offering a more comprehensive diagnostic approach.
Conditions Diagnosed with EEG
EEG and Video EEG are invaluable in diagnosing and managing various neurological conditions, including:
Epilepsy: Identifies seizure activity and determines seizure types.
Sleep Disorders: Evaluates issues like sleep apnoea, narcolepsy, and insomnia.
Brain Tumours: Assesses the impact of tumours on brain activity.
Stroke: Detects abnormal brain function following a stroke.
Head Injuries: Evaluates the effects of trauma on brain function.
Encephalitis: Monitors inflammation-related brain activity changes.
Benefits of EEG and Video EEG
These diagnostic tests offer several key advantages:
Non-Invasive: The procedure is painless and does not involve surgery.
Accurate Diagnoses: Provides precise data on brain activity to guide treatment decisions.
Real-Time Monitoring: Video EEG captures simultaneous video and brain activity to identify seizure triggers and patterns.
Safe for All Ages: Suitable for children and adults, including pregnant individuals.
How is an EEG or Video EEG Administered?
The procedure typically involves the following steps:
Preparation: The patient’s scalp is cleaned, and electrodes are placed using a conductive gel. For Video EEG, a camera is positioned to record physical movements.
Recording: The patient is asked to relax while brain activity is recorded, often lasting 20-40 minutes for a standard EEG. Video EEG monitoring may last several hours or days to capture rare events.
Analysis: A neurologist analyses the recorded data and video footage to identify abnormalities.
Potential Side Effects
EEG is a safe and well-tolerated procedure. Some patients may experience minor skin irritation from the electrode gel, but no long-term side effects are associated with this test.
