Is your child having trouble completing a task? Does he struggle to stay in one place for a while? Or is he just not paying attention in class? As a parent, it's normal to feel a little scared and worried when you see things like this. You may have heard of a condition called ADHD . So today we're going to talk about what ADHD is and whether, as some people say, it can really be diagnosed with an EEG test.
First of all, what exactly is ADHD?
Simply put, ADHD, or Attention Deficit Hyperactivity Disorder , is a condition that affects the development and functioning of a child's brain. It's not a bad thing for the child or a mistake in parenting. It's a medical condition.
A child with ADHD can have two main categories of symptoms:
- Inattention : They have difficulty paying attention to one thing for long periods of time. They are easily distracted. This is especially noticeable when listening to a lesson in class, doing homework, or assembling a toy.
- Hyperactivity and Impulsivity : This includes things like being unable to sit still, constantly fidgeting, not waiting for one's turn, and suddenly interrupting others when they are talking.
The important thing is that a child cannot be diagnosed with ADHD just because they have one or two of these symptoms. A doctor diagnoses the condition after studying the child's behavior in depth for at least 6 months , at home and in several settings , such as school, and after obtaining information from parents and teachers.
So, what is this EEG test?
EEG is short for Electroencephalogram . It measures the tiny electrical waves in our brain and records them on a computer screen. Think of it like taking an ECG to check the heart's activity, this measures the activity of the brain .
This is a painless and very safe test. It involves placing small metal plates (electrodes) on the scalp. Sometimes a special cap is worn for this. The signals from these plates are recorded by a computer.
Doctors use EEG tests to diagnose a number of other conditions in addition to ADHD.
| Other cases where EEG testing is used |

| To diagnose seizure disorders such as epilepsy . |
| If there is a suspicion of a brain tumor . |
| To check for sleep disorders . |
| To assess brain damage after conditions such as stroke . |
How is an EEG used to diagnose ADHD?
Research has found that the brainwave patterns of people with ADHD are slightly different from those without the condition. This difference is the basis for attempts to use an EEG to diagnose ADHD.
There is a system specifically designed for this purpose, called the Neuropsychiatric EEG-Based Assessment Aid (NEBA) System . The FDA in the United States approved this system in 2013. But it is only for children between the ages of 6 and 17 .
The NEBA system measures theta waves, a type of slow brain waves, and beta waves , a type of fast brain waves, and calculates the ratio between the two. The idea behind this is that children with ADHD have a higher ratio.
Is this method really effective? What do scientists say?
This is where it gets most important and a bit complicated. There are different opinions about this method.
One study showed that when the NEBA system was combined with the usual methods used by doctors to diagnose ADHD, the accuracy of the diagnosis increased from 61% to 88% . This means that it is of some help. In particular, the study said that it could be useful in differentiating ADHD from other conditions with similar symptoms.
However, many scientists and doctors are still skeptical about this method. They say that there is not enough research to determine whether ADHD is present or not based solely on these EEG results.
Why do they say that?
The main reason is that many other things can affect brain wave patterns. For example, if the child is a little sleepy at the time of the test, it can change the brain wave patterns. It is difficult to completely trust the results obtained at such a time. Therefore, some say that these results are not very reliable.
What should you do as a parent?
With all of this said, if your doctor suggests an EEG to see if your child has ADHD, there are a few things you should be aware of.
1. Be open: Talk openly with your doctor about the pros and cons of this test. Don't be afraid to ask questions like, "Doctor, how sure are the results of this test?"
2. This is not the only factor: Keep in mind that an EEG test is only one small part of the ADHD diagnosis process. It can never be determined that a child has ADHD based on the results of this test alone.
3. A complete medical examination is essential: A diagnosis of ADHD requires a complete and comprehensive medical evaluation . The doctor will definitely need to obtain information from you , the parent, the child's teachers , and other caregivers. It is essential to take a deep look at the child's behavior, learning problems, and social interactions.
Simply put, comparing the results of an EEG with all the other information a doctor collects is like putting together pieces of a puzzle. You can't see the whole picture with one piece.
Take-Home Message
- ADHD is not the child's fault, but a medical condition related to brain function. It should be diagnosed by a qualified doctor.
- EEG is a painless, safe test that measures electrical waves in the brain.
- Although a special EEG method called NEBA is used to help diagnose ADHD, there is scientific controversy about its success and reliability.
- A child should never be diagnosed with ADHD based solely on the results of an EEG test. It is only one aid in the diagnostic process.
- If you have any doubts about your child's condition, it is very important to discuss it with your doctor and reach an accurate conclusion through a complete medical evaluation.
