EEG Meaning and
Definition
-
EEG, short for electroencephalogram, refers to a diagnostic test used to measure and record electrical activity in the brain. It is a non-invasive procedure that involves the placement of small, flat metal electrodes on the scalp, which detect and record the electrical impulses generated by brain cells, also known as neurons.
The electrical signals recorded by an EEG machine are represented as a series of waves or patterns, and these can provide valuable information about brain function and activity. The examination is primarily used to detect and diagnose various brain conditions and disorders such as epilepsy, brain tumors, sleep disorders, and brain injuries.
During an EEG, the patient is required to lie down in a relaxed state with their eyes closed or open, and sometimes specific instructions, such as deep breathing or rapid eye movement, might be given. The test typically lasts for about 60 minutes and is painless, although slight discomfort may arise due to the adhesive applied to attach the electrodes.
Interpretation of an EEG is performed by a trained physician or neurologist who examines the recorded brainwave patterns. Abnormalities in the EEG can indicate the presence of seizures, abnormal brain activity, or other neurological disorders. The results of an EEG are critically important for the diagnosis, treatment, and ongoing monitoring of various brain disorders in both adults and children, helping healthcare professionals develop appropriate treatment plans tailored to each individual's needs.
Common Misspellings for EEG
Etymology of EEG
The word "EEG" stands for electroencephalogram, which is a medical term used to describe a test that measures electrical brain activity. The etymology of the word "electroencephalogram" can be broken down as follows:
1. Electro-: Derived from the Greek word "ēlektron", meaning "amber" or "electron". This component indicates the use of electricity in measuring brain activity.
2. Encephalo-: Taken from the Greek word "enkephalos", which means "brain". It refers to the central part of the nervous system in vertebrates.
3. -gram: Derived from the Greek suffix "-gramma", meaning "something written" or "record". In the context of EEG, it refers to the graphical representation or record of electrical brain activity.
