Neurofeedback technology is an innovative way to treat attention deficit disorder and insomnia by modulating brain waves. But does it really work?
Attention deficit disorder and insomnia are serious mental illnesses in the modern world. The brain waves of people with these conditions are different from those of normal people, and it”s believed that modulating their brain waves can cure them. This technique is called neurofeedback. Let’s take a look at the process of diagnosing and treating diseases with neurofeedback.
First, electrodes are placed on the patient”s scalp to collect brain waves, a type of bioelectrical signal. Brain waves are very weak, so we need to amplify them by applying a strong voltage to the input brain waves through an amplification circuit. However, the brainwaves are also subject to changes during small movements such as blinking, so a filter circuit is used to filter out the main brainwaves and find the dominant frequency band. Finally, the analog brain waves must be converted to digital waves using an A/D converter so that they can be easily viewed on a computer screen.
In this process, we can see that people with attention deficit disorder have stronger delta and theta waves than normal people, and that people with depression have faster oscillations in the right brain than in the left.
Brain waves are an important indicator of our physical and mental state, and must be regulated to maintain normal activities and states. In particular, neurofeedback has been recognized as a highly effective way to control and modulate these brain waves. In the modern world, attention deficit disorder and insomnia are common problems, and they are becoming more frequent due to stress and excessive information exposure. Therefore, there is an ongoing interest and research in brainwave modulation techniques.
So, how do we treat these patients? The principle is simple. For example, for patients with attention deficit disorder, it’s hard for them to know when they’re focused, so by showing them their brain waves in real time on a screen, they can practice getting into that state of focus, which is to say, by having them think about different things and noticing when the beta waves associated with focus come on, and then giving them feedback to help them stay in that state. It’s like the conditioned reflex that Dr. Pavlov discovered: if you tell a patient that a certain brain wave is produced, they’ll try to stay in that state. The brain then develops a circuit to generate the brainwave, and with continued training, the circuit is strengthened and the specific brainwave increases.
In fact, in 1971, Dr. Luba successfully treated attention deficit disorder with neurofeedback using beta waves, and in 1995, Dr. Rosenfeld successfully treated depression with neurofeedback training that balanced the speed of brain waves in the left and right hemispheres. The benefits of neurofeedback don’t stop there. Recent studies have shown its usefulness for autism, anxiety disorders, and even chronic pain management. It’s also increasingly being used by athletes and artists to improve their performance. This is done in an effort to manipulate brainwaves to stay in the best mental state and maximize concentration.
Currently, neurofeedback is being used to treat a variety of conditions, including autism and insomnia. The advances in this technology are giving many people new hope and are moving us closer to maximizing the brain’s potential. With continued research and clinical applications, neurofeedback is expected to become more widely used and help solve a variety of mental and physical problems.
