“What is QEEG?” is a great question to ask but before giving an answer to that question, let us give a brief information why we need such a thing? The human brain is an incredibly complex organ that has the power to control every single aspect of our lives, from how we think and feel to what we do. However, with this complexity comes some not-so-good traits, such as mental illness which affects one in five people worldwide (NIMH).
To help improve diagnoses of various conditions like major depressive disorder or attention deficit hyperactivity disorder (ADHD), many psychologists are turning towards a relatively new method called quantitative electroencephalography (QEEG) topographic brain mapping. This article will describe what QEEG is and give you an idea of why it may be useful for the medicine world!
What is QEEG?
It is a technique that shows the distribution of waves of different frequencies on the brain by analyzing the brain electrical activity record taken from the scalp, and thus provides indirect information about the functioning of the brain. When QEEG is repeated after treatment, it can show the positive change achieved with treatment. As can be understood from the profiles obtained before and after the treatment in the samples, it can be observed with the bioelectrical activity recording that the treatment eliminates the irregularities in brain chemistry. This article tries to give answers to the questions like “What is QEEG?”, “What are its usage areas?”, etc.
Since many mental illnesses are brain diseases, understanding and monitoring brain function is important for an effective treatment. In the treatment of depression, monitoring the psychological or social dimension as well as the biological dimension is especially valuable and a priority in treatment-resistant cases.
Treatment by measuring brain functions in adults, adolescents and children is a missed and targeted goal in psychiatry. It is possible to measure bioelectric activity, which is the end product of biological processes in the brain, with QEEG.
Where Is QEEG Used?
The biological dimension of many psychiatric diseases, especially depression and panic disorder, has been confirmed by scientific research. The relationship between biochemical disorders and these diseases in some areas of the brain has been shown in laboratory studies. However, the extraordinarily complex structure and “immunity” of the human brain pose a strong obstacle to the detailed analysis of this relationship. Since the human brain cannot be seen directly, and a part of it cannot be taken and examined like in other organs, researchers use techniques that can give information about the functioning of the brain “indirectly”.
