Encephalography or EEG is a type of test that is used to evaluate the electrical activity of the brain and can help identify possible problems with brain cells. In this method, the doctor attaches small metal discs called electrodes to the scalp and uses them to track and record brain wave patterns.

Electrodes analyze the electrical impulses in the brain and record their results.. The results of the EEG are recorded as waveforms and allow doctors to check if there are abnormal patterns in the brain. Is it?..

What is the brain strip for diagnosis?

Electroencephalogram has been used since 1929 to identify problems in the electrical activity of the brain that are related to brain disorders. The applications of this diagnostic method include:

1... Brain scan to diagnose MS

Although brain scans are not used for the initial diagnosis of MS, research shows that the disease can be more accurately diagnosed using EEG signals.

2.... diagnosis of head injury

Research shows that some people function normally for up to 15 minutes after a head injury....Using an electroencephalogram, doctors can diagnose head injuries and take necessary measures faster than a neurological examination.

3... diagnosis of seizure disorders (epilepsy)

Electroencephalography is one of the main methods for evaluating a patient with epilepsy... Doctors also use this method to classify the type of epilepsy syndrome.

4.... Diagnosis of depression by brain scan

Experts use electroencephalogram as a non-invasive method to investigate mental disorders such as depression, anxiety, psychosis, and sleep disorders. Mental disorders are associated with irregular brain activity and significant emotional fluctuations. Therefore, this method can be used to monitor the brain and identify patterns of mental disorders.

5.... Diagnosis of brain tumor

Doctors do not use electroencephalography as a primary tool for brain tumor diagnosis... Brain tumors are usually diagnosed through imaging methods such as MRI or CT-Scan and biopsy (removal of tissue and testing).

However, an EEG can provide doctors with valuable information about brain tumors. For example, if a tumor impairs a certain brain function, such as movement or speech, the EEG can map patterns of impairment in that function.

6... diagnosis of sleep disorders

Electroencephalogram is a common method to monitor brain activity and diagnose sleep disorders.... Recording each EEG takes about 8 hours on average.... Therefore, this method is a time-consuming task for a sleep specialist, and doctors may use other methods to diagnose these disorders.

7... EEG for migraine

Electroencephalogram is usually the first test that is prescribed to diagnose migraine. In the later stages, the doctor uses other imaging methods such as MRI for a more accurate diagnosis.

8... Dementia diagnosis with electroencephalogram

Electroencephalography is a useful tool in the diagnosis of dementia and can measure the electrical activity of the brain and detect abnormalities that indicate dementia.

Is it dangerous to have a brain scan?

Electroencephalogram is usually painless.. However, when a person has epilepsy or another seizure disorder, there is a risk that the stimuli presented during the test will trigger a seizure..

1... Brain scan in pregnancy

Electroencephalogram does not contain radiation and its electric currents are applied only locally on the scalp. Therefore, performing this diagnostic procedure during pregnancy and under the supervision of a doctor does not pose any particular risk to the mother and the fetus.

2... Brain tape for children

Brain scan of children is also safe.. because in this method there is no x-ray, drug injection and electric shock... Some children may fear that the device can read their thoughts or dreams, in this case it is important to reassure your child that nothing will happen to them.

Points to follow before EEG

Before doing this test, pay attention to the following points:

• If you are taking medication, inform your doctor.
• Wash your hair the night before the test and do not use any hair styling products on the day of the test.
• Avoid eating or drinking foods containing caffeine for at least 8 hours before the test.
• Be sure to have as many people with you as possible before the test. Do it.

Interpretation of brain tape

The interpretation of this test must be done by a neurologist.... If the EEG is normal, it means that different levels of consciousness, such as sleep and wakefulness, are in a certain range of wave frequencies. LLC

Summary

In this article, we examined the use of EEG and its interpretation.... Remember that factors such as pulse and heart rate, breathing, perspiration, mouth movements, muscle movements, low blood sugar, greasy hair and caffeine consumption can affect the EEG results... Inform the neurologist.
