Dyslexia affects about 10% of the world's population

There are many diseases in the world that are associated with disorders of the brain and spinal cord, as well as various groups of nerves. These diseases are called neurological disorders and one of the most common of them is considered dyslexia. The exact cause of this disease is still unknown, but in what it manifests is already well known. People with dyslexia are hard to learn the skills associated with writing and reading. Due to reading and writing difficulties, dyslexics often lag behind in learning, which negatively affects the quality of their adult life. Since the exact cause of dyslexia is unknown, there is no effective treatment for the disease either. But recently, researchers in Switzerland have come a step closer to creating this technology - they made it easier for patients to read by affecting their brains with small electrical discharges.

What is dyslexia?

According to the researchers, today about 10% of the world's population suffers from dyslexia. This disease is quite difficult to diagnose, especially in school-age children. Most often, suspicions arise when the child is given much more difficult reading and writing than classmates. Because of problems with these skills, children with dyslexia have big problems with other school subjects. In the end, this sometimes results in serious difficulties in adulthood. It is important to understand that dyslexia manifests itself in different ways. Patients usually have one or more of these problems:

• Reading difficulties
• Complexity with the letter
• Literacy problems
• Math problems
• Impaired coordination of movements;
• inability to concentrate.

The brains of healthy people and dyslexics work differently

Treatment of dyslexia

The treatment of dyslecia is handled by a speech therapist. Due to the high prevalence of the disease, in some schools in major cities the speech therapist is a full-time employee. The treatment of dyslexia is mainly reduced to exercise from Ronald Davis's book The Gift of Dyslexia. They aim to teach dyslexics to get rid of distortions that occur when reading and writing, with the help of imagination. It sounds like something complicated and impossible, but from this method of treatment really is the result, because it was developed by a person who himself suffered from dyslexia. It is known that Ronald Davis was born with autism and remained illiterate until the age of 38. The methods developed helped him to eliminate all problems.

As mentioned above, the exact cause of dyslexia has not yet been identified. But there are several assumptions that I can believe in. One version says that a neurological disorder occurs due to a phonological deficiency. By this term it is customary to understand the phenomenon in which the human brain hardly correlates the sound of letters with their writing. But it is important to understand that this mechanism can be explained only one of the manifestations of dyslexia, but there are many of them. So, in each particular case, the reason should be different.

Brain function in dyslexia

But there is a more general explanation for the development of dyslexia. In the course of several scientific papers, scientists have found that dyslexics have problems with the so-called left auditory cortex. It is responsible for sound processing and works at 30 Hz, but dyslexic frequencies vary. Based on the fact that brain activity can be influenced by the influence of the magnetic field, researchers from Switzerland hypothesized that when normalizing brain frequencies dyslexia in patients should pass. To test their theory, the scientists conducted an experiment.

This is what the brain stimulation process looks like

On the heads of 30 people were found "caps" with electrodes, generating a magnetic field. One half of the volunteers suffered from dyslexia, while the other half had no problems with writing and reading. To the surprise of the authors of the scientific paper, when the magnetic field stimulated the left auditory cortex to work with a frequency of 30 Hz, dyslexics really began to read well. But people who have already read well, stimulation on the contrary interfered.

At the moment it is a very superficial experiment and scientists should conduct an experiment involving more people of different sex and age. It is necessary to find out how long the effect persists and whether such therapy has negative consequences. The results of the scientific work were published in .

In general, electrical stimulation of different organs is quite capable of endowing people with superhuman abilities. In 2019, I told how by influencing a person's muscles with electricity, it is possible to increase its reaction and accuracy several times. You can read more about this technology.
