Dyslexia

Dyslexia is a brain-based type of learni                                                                                                                                                                                                                                     ng disability that specifically impairs a person's ability to read. These individuals typically read at levels significantly lower than expected despite having normal intelligence. Although the disorder varies from person to person, common                                                                                                                              processing (the manipulation of sounds), and/or rapid visual-verbal responding. This is a very difficult illness because, people that are suffering, it have a lot problem in their life. For example student from different institutions are having serious problems in the different subjects such as math, Spanish and English, it really comes different troubles, for example students use to made a lot of mistakes, they are not able to understand some reading or writing, they use to confuse words and numbers, it is causing serious problems  in the grades. Let see some Signs and symptoms of dyslexia;
  • delays in speech
  • slow learning of new words
  • not crawling
  • difficulty in rhyming words, as in nursery rhymes
  • low letter knowledge
  • letter reversal or mirror writin (for example, "Я" instead of "R")
They were the most typical signs and symptoms of dyslexia and let’s know   a little bit about causes:
The Cerebellar Theory asserts that a mildly dysfunctional cerebellum can cause dyslexia. The cerebellum contributes to motor control during the articulation of speech, and the Cerebellar Theory proposes that articulation problems can contribute to the phonological processing deficits that can cause dyslexia. The Cerebellum also contributes to the automatisation of learnt behaviors, which includes learning the grapheme–phoneme relationships when reading text.
