The EEG machine is a device that monitors brain activity by measuring the changes in electrical currents in the brain, and then converts these measurements into a visual form.
An EEG can be a great medical tool for making a diagnosis if you have a disorder or ailment that has a neurological basis. An electroencephalogram, or EEG, can give a neurologist a better understanding of what is happening in your brain. This can help a medical professional identify particular health conditions, such as epilepsy, brain tumours, head injuries, sleep disorders, or abnormal or subnormal behaviour.
One question must be addressed in order to evaluate whether an EEG test is useful: “How can an EEG system help you?”
There are many billions of nerve cells in the brain. Small electrical pulses generated by these cells form patterns known as brain waves. A skilled specialist attaches a number of cords and electrodes to your head and scalp during an EEG. This is carried out in order for the EEG to capture brain wave activity. The electrical signals are amplified and recorded by the electrodes.
An EEG is frequently carried out to verify the existence of the following:
- Difficulties with the nervous system
- Spinal column or brain issues
- Behavioural health issues
In order to make a proper diagnosis, patients exhibiting symptoms of brain disorders should have an EEG. However, there are additional uses for an EEG that are not diagnostic in nature. An EEG is used to monitor a person’s brain activity while they are under anaesthesia as well as to assess their odds of waking up from a vegetative state, in addition to being helpful in the diagnosis of the aforementioned illnesses.
The electrical impulses in the brain are measured by an EEG examination. As a result, contrary to what some believe, it is not intended to transfer electricity to the brain. It is simply used to track aberrant brain activity. For instance, if you experience seizures, an EEG reveals the source of any aberrant activity, making it useful for detecting diseases like epilepsy.
You might be required to participate in video EEG ambulatory tracking if the regular test does not successfully identify the correct brain wave patterns.
EEG testing is mainly used by neurologists to identify and treat epilepsy, as well as sleep disorders like narcolepsy and insomnia, a variety of brain tumours, brain damage, infections of the brain, dementia, attention deficit disorder, behavioural delays in children, and behavioural disorders that interfere with daily activities. They can figure out how and why a patient is in pain, uncomfortable, or having problems physically or mentally by looking at brain wave patterns.
