EEG during sleep
Sleep helps to induce abnormal electrical activity in the brain. In cases where the EEG does not provide enough information for 20 minutes of awakening for the diagnosis of epilepsy, the EEG is taken in the sleep. Sleep EEG is one of the most commonly used activation methods.
It is useful for the patient to be asleep the night before the EEG recording, to make it easier to sleep during the day, or to increase the likelihood of abnormal brain waves.
The electrical activity produced by nerve cells in the brain, both during wakefulness and sleep, is printed on the paper in the form of brain waves.
WHEN SHOULD EEG DO?
The normal electrical activity of the brain is disturbed in many cases, especially epilepsy. Assessment of brain waves that make up the EEG provides information about the location and form of this disorder. In many neurologic diseases except epilepsy, EEG examination is used to investigate the causes of headaches and to evaluate brain functions. In particular, the method of examination that will determine the causes of fainting, the diagnosis of epilepsy and the determination of its type is EEG.
HOW IS IT EEG RECORDING DONE?
The electrical activity of the brain is transmitted to the EEG device by small metal electrodes placed on the scalp hair of the patient and the data is recorded on the computer for about 20 minutes. There is no electricity to the patient during the shooting and the patient does not feel any pain. EEG can be withdrawn in all age groups and during pregnancies. It does not contain radiation.
PREPARATIONS BEFORE RECORDING?
Before EEG is useful to wash your hair in the morning of the shooting of the day in order to avoid interference in the examination of the EEG. If there are drugs that are used continuously, medication will continue to be used on the day of shooting, and the physician who will evaluate the EEG should be informed about this issue.
Electromyography is the electrical monitoring of the nerves and muscles in our body. EMG examination examines whether the peripheral nerves in the head, arms, legs and body are functioning normally.
IN WICH CASE IS EMG REQUIRED?
- Nerve injuries
- Nerve jams (Carpal tunnel syndrome, etc.)
- Waist and neck hernias
- Symmetrical and burning patterns on arms and legs
- Facial paralysis
- Diagnosis of diseases that impair the functions of nerves (metabolic diseases like diabetes)
- Diagnosis of muscle diseases
- During the diagnosis of diseases of the spinal cord passing through the muscles
