The Role Of An EEG Test

What is an EEG Test?

If we go about with the definition of an Electroencephalogram Test or an EEG Test is basically used to evaluate the complete electrical activity in the brain. It is our brain cells that always communicate with each other through some electrical impulses. Hence, an EEG Test, can be used to help and detect the potential problems associated with this particular activity.

The test is initiated to both track and record the brain wave patterns. Small, with some flat metal discs called electrodes are indeed attached to the scalp with wires. All these electrodes actually analyse the electrical impulses in the brain and hence, send the signals to a computer, where the immediate results are actually recorded.

All the electrical impulses in the so-called EEG recording is said to look like some wavy lines with various peaks and valleys. These are the lines that actually allow doctors to indeed quickly assess whether there are some abnormal patterns. Any kind irregularities may always be a sign of some kind of seizures or any other brain disorders.

Why an EEG is basically performed?

The Purpose

An EEG is used to detect problems in the electrical activity of the brain that may be associated with certain brain disorders. The measurements given by an EEG are used to confirm or rule out various conditions, including:

  1. Some seizure disorders
  2. A complete head injury
  3. The Encephalitis
  4. Brain Tumour
  5. The Encephalopathy
  6. The Memory Problems
  7. Acute Sleep Disorders
  8. Stroke
  9. The Dementia

This is in fact, the kind of test that is also used to monitor the brain activity during surgery.

The risk factors associated with an EEG Test ?

There are in fact, no risks associated with an EEG Test. This is definitely one of the painless test and safest.

When someone is suffering from epilepsy or any other form of seizure disorder, then the stimuli presented during the test may indeed cause for a seizure. However, it is the original technician who is performing the EEG test and is at the same time trained to safely manage the situation, should this actually occur.

What do the test results mean?

Neurologist is someone is on a A WHO COMPLETE indeed the specializes in nervous system disorders, and at the SAME time Interprets the recordings taken from the EEG Test . This is sent to your doctor, and the report is disclosed to the patient.

The Normal Results:

The complete electrical activity in the brain is definitely seen in an EEG Test and also as a pattern of waves. The various levels of consciousness, such as sleeping and even waking, have some specific range of frequencies of waves per second that are actually considered normal.

The Abnormal Results:

The Abnormal EEG results may be owing to the following reasons:

  1. The occurrence of epilepsy or another seizure disorder
  2. Some abnormal bleeding or even at times haemorrhage
  3. The acute sleep disorder
  4. The encephalitis (swelling of the brain)
  5. A tumour
  6. The dead tissue due to some blockage of blood flow
  7. An acute migraines
  8. Some kind of alcohol or drug abuse
  9. Some severe head injury
