EEG test cost in India ranges from Rs.1000/- to Rs.3500/-. An EEG evaluates the electrical activity of the brain. It is a non-invasive monitoring method that records the patterns of electric impulses through which brain cells communicate. EEG uses small sensors, known as electrodes that are placed on the scalp. These electrodes are connected to an EEG recording machine with wires. The brain waves are tracked by the electrodes and sent to a computer where the results are recorded.
The EEG recordings of the brain waves look like a wavy line with peaks and valleys. With the analysis of these recordings, doctors can detect the abnormalities in the brain wave patterns which helps in the diagnosis of brain and sleep disorders, especially epilepsy. EEG is prescribed to detect the problems in brain activity that may be associated with certain brain disorders. It is used to either diagnose or treat various conditions such as brain tumors, stroke, damage from head injuries, sleep disorders, etc. In the case of persistent coma, EEG might be used in confirming brain death.
