EEG (Electroencephalogram)
EEG is a non-invasive test that records electrical activity of the brain using electrodes placed on the scalp. It helps in evaluating and diagnosing a variety of brain disorders, especially seizure disorders.
What Does EEG Detect?
- Brain waves - Electrical impulses in the brain
- Helps detect abnormalities in brain activity patterns
How EEG Works
Recording brain's electrical activity
Electrode Placement
Electrodes are placed on the scalp using a special adhesive paste
Brain Wave Recording
Electrodes detect brain waves (electrical impulses in the brain)
Signal Amplification
Signals are amplified and sent to recording equipment
Pattern Analysis
Brain activity patterns are displayed and analyzed for abnormalities
What Does EEG Detect?
Comprehensive brain activity assessment
Brain Waves
Records electrical impulses in the brain
Abnormal Patterns
Detects abnormalities in brain activity patterns
Seizure Activity
Identifies epileptic discharge patterns
Brain Dysfunction
Reveals areas of impaired brain function
Common Uses of EEG
Wide range of neurological applications
Epilepsy & Seizures
Most common use - detecting and monitoring seizure disorders
- Seizure diagnosis
- Epilepsy evaluation
- Seizure type classification
- Treatment monitoring
Unconsciousness or Coma
Evaluating brain function in unconscious patients
- Coma assessment
- Brain death evaluation
- Consciousness level monitoring
- Prognosis determination
Sleep Disorders
Diagnosing sleep-related brain activity issues
- Narcolepsy diagnosis
- Sleep apnea evaluation
- REM sleep disorders
- Abnormal sleep patterns
Encephalopathy
Detecting brain dysfunction and metabolic issues
- Metabolic encephalopathy
- Toxic encephalopathy
- Brain inflammation
- Cognitive dysfunction
Brain Tumors or Stroke
Identifying structural brain abnormalities
- Tumor location
- Stroke assessment
- Brain lesion evaluation
- Focal abnormalities
Surgery & ICU Monitoring
Monitoring brain activity during critical care
- Intraoperative monitoring
- ICU brain function
- Anesthesia depth
- Critical care assessment
Most Common Use
Epilepsy & Seizures is the most common use of EEG testing. It's the primary diagnostic tool for detecting and classifying seizure disorders, monitoring treatment effectiveness, and distinguishing epileptic from non-epileptic events.
