Dyslexia, with over a hundred different symptoms, has a variety of different and unique treatments that seek to drastically improve or eliminate these symptoms. The only medical treatment utilizes antimotion-sickness medication in order to improve the dysfunctioning of inner-ear-related mechanisms, the primary cause of symptoms for 75-85% of dyslexics. Many doctors have also found success in treating dyslexic patients through eating ordinary foods; ginger root, lecithin, and ginkgo are all shown to improve symptoms. Repetition of motion-related and eye-training exercises not only improve sensory and motor mechanisms of a dyslexic, but also allow them to read, write, and concentrate better. Interestingly, because many sports exercise sensory and motor mechanisms, dyslexics who are athletes improve the condition of their dyslexic symptoms; yoga is an extremely effective way to improve symptoms because it is a combination of movement, timing, concentration, and enhancement all at once. Although there are educational therapies that try to pinpoint and improve symptoms in dyslexics, incredible results are hard to come by; instead, doctors use visual and auditory therapy in order to imprint words and improve balance and coordination circuits in the body. In addition, psychotherapy is capable of alleviating stress and feelings of frustration and helplessness, and by lowering the impact of factors that destabilize the system, an individual is capable of attaining maximum overall improvement. Lastly, a quick method of improving symptoms of dyslexia is the use of tinted and magnification lenses in order to minimize or compensate for various reading symptoms of dyslexia, allowing individuals to better concentrate on words.
