Dyslexia mostly appears in the early years of life, affecting kids and teens. The main symptom of all cases of dyslexia is a significantly lower reading ability than normal children of the same age and intelligence. Other symptoms common among dyslexics include: difficulty in learning and memorizing written words, excluding and/or including words during reading, reversing the order of letters in words or wrong reading of numbers, incorrectly spelling words, substituting vowels or consonants for the vowels or consonants that are actually part of the written text.
Some dyslexics have difficulty in learning writing and/or acquiring adequate speech. Some experience difficulty in picking the appropriate word for expressing their thought meaningfully. A general, though not precise, indicator of dyslexia is clumsiness. This does not mean that dyslexic children develop poor reading due to a lower socio-cultural background. Most of these children and teens come from average or good familial backgrounds. However, studies reveal that dyslexia runs in families, i.e. children of dyslexic parents are more likely to suffer from dyslexia.
The diagnosis of dyslexia in children involves both physical and psychological testing. The physician usually takes a medical history of the dyslexic and checks other variables so to make sure there are no other causes than problems with the Central Nervous System (CNS) that are causing the difficulty in reading. The psychologist identifies the specific types of reading mistakes which the dyslexic individual makes more frequently. Treatment is directed at remedying those mistakes.
Treatment of Dyslexia addresses the specific reading problems (spelling difficulty, reversing word order etc.) and attempts to correct them by necessary modification in particular methods of teaching as well as in the general educational environment. A single method of treatment does not work for all dyslexics and a variety of listening, writing, and speaking techniques is employed to treat dyslexia in any individual case.
To date there has been no known method of preventing dyslexia. However, nutritionists emphasize the importance of certain nutrients whose adequate intake can minimize the risk of developing dyslexia. Research reveals that majority of dyslexic children are deficient in essential fats, i.e. omega 6 and omega 3 fatty acids. Omega 6 fatty acids are found in vegetable oils, sunflower and corn oil. Omega 3 fatty acids can be obtained through flax seed, soybean, walnut, and chestnut oils. Cold-water fish and dark green leafy vegetables also provide some of the essential fatty acids. An increased amount of these foods might help prevent dyslexia.
