A normal EEG (electroencephalogram) reading typically shows a rhythmic pattern of brain waves, which can be categorized into different frequency bands:
Frequency Bands
1. *Delta waves* (0.5-4 Hz): Present during deep sleep, unconsciousness, and in infants.
2. *Theta waves* (4-8 Hz): Seen during drowsiness, sleep, and meditation.
3. *Alpha waves* (8-12 Hz): Typical of relaxed, closed-eyes state.
4. *Beta waves* (13-30 Hz): Present during active thinking, problem-solving, and motor activity.
5. *Gamma waves* (30-100 Hz): Associated with higher-level cognitive processing, attention, and working memory.
Normal EEG Patterns
1. *Alpha rhythm*: A prominent alpha wave pattern (8-12 Hz) is typically seen in the posterior regions of the scalp.
2. *Beta activity*: Beta waves (13-30 Hz) are usually seen in the frontal and central regions.
3. *Sleep spindles*: Brief, synchronized bursts of activity (12-16 Hz) during stage 2 non-REM sleep.
4. *Vertex waves*: A sharp, negative wave (100-200 ms) seen during stage 1 non-REM sleep.
Abnormal EEG Patterns
Abnormal EEG patterns can indicate various neurological conditions, such as:
1. *Seizures*: Sudden, high-amplitude discharges.
2. *Epilepsy*: Recurring seizures or abnormal electrical activity.
3. *Encephalopathy*: Slowed or disorganized brain activity.
4. *Stroke*: Focal or generalized slowing of brain activity.
Keep in mind that EEG interpretation requires expertise and should only be performed by a qualified healthcare professional. #EEG #EEGTest #EEG2024 #eeggattummaa Ïzãz Khäñ Muhammad Usama @highlight
