Dyslexia
Dyslexia is a learning impairment characterized by difficulties understanding speech sounds and learning how they relate to letters and phrases. Dyslexia, also known as reading disorder, affects the parts of the brain that interpret language. The causes of dyslexia differ depending on the type. Most of the study into primary dyslexia focuses on genetic grounds. According to scientists, specific genes have recently been described as potentially leading to the signs and symptoms of dyslexia.
Types of Dyslexia
- Phonological Dyslexia.
• Surface Dyslexia.
• Visual Dyslexia.
• Primary Dyslexia.
• Secondary/Developmental Dyslexia.
• Trauma Dyslexia also referred to as Acquired Dyslexia.
Signs and symptoms
Delayed speech onset and a lack of phonological awareness are early childhood symptoms that correlate with a later diagnosis of dyslexia. Dyslexia is often associated with mirror writing and reading letters or words backward, according to popular belief. Many children exhibit these behaviors as they learn to read and write, and they are not considered dyslexic characteristics.
Dyslexic school-aged children may struggle to identify or generate rhyming words and count the number of syllables in words, both of which require phonological awareness. They may also have trouble segregating words into individual sounds or blending sounds when telling stories, both of which indicate a lack of phonemic awareness. Dyslexia is linked to difficulties with words and naming objects. People with dyslexia are frequently poor spellers, a symptom known as dysgraphia and which is based on orthographic coding.
Problems with summarizing stories, memorization, reading aloud, and learning foreign languages can continue into later life. Individuals with dyslexia often can read with good comprehension, though they read more slowly than those who do not have any learning disability and perform worse in spelling tests.
Emotional and social impacts of Dyslexia
Dyslexia influences a child's social life as well. In addition to reading and writing difficulties, a dyslexic person with word-finding problems can have trouble with their expressive language, which has a social impact and makes you feel less valuable about yourself. Dyslexic children, especially those who have not yet been diagnosed, often have low self-esteem because they believe something is wrong with them. People with dyslexia may never enjoy reading and may want to stop it at all costs. However, every child is uniquely affected by dyslexia.
Dyslexia is a lifelong condition. On the other hand, involvement and adequate training will go a long way toward assisting children with reading difficulties. Assistive technology, such as text-to-speech, plays a role as well. Child support from you is equally critical. Knowing that dyslexia poses ongoing problems helps you concentrate on getting him the support he needs now and in the future.
Conclusion
Dyslexia can be linked to variations in a network of regions involved in normal reading formation. Even in infancy, neural signatures that could suggest potential reading difficulties exist, implying that detecting reading problems before a child fails to learn to read and falls behind may be feasible. In light of current educational methods and policies, there is a lot of discussion about how a better understanding of the brain basis of dyslexia could or might not be helpful. Despite the fact that neuroimaging experiments have shown that dyslexia is caused by functional and systemic brain changes that begin in childhood and diverge from average brain growth, reading training does not target specific neural systems. Instead, teaching focuses on interpersonal skills like phonological comprehension, which is a part of single-word decoding. The prediction of reaction to instruction, which would encourage customized or individualized instruction, is one field where neuroimaging studies can add educational value.
Children with dyslexia are now offered a form of remediation that tends to be beneficial for about half of the children who undergo it under ideal circumstances. However, the efficacy of a system of instruction is currently only understood after a time of sustained failure in children who do not respond. According to neuroimaging tests, such a variable response to reading instruction may be expected before it starts. In that case, children should be led to alternate means of remediation from the onset, which are more likely to be helpful to each child personally. Despite the fact that existing instructional interventions are ineffective at recognizing instruction-relevant variance, neuroimaging studies suggest that it is feasible. With advancements in neuroimaging, some form of adaptation of neuroimaging results to meaningful educational measures will almost definitely be needed. On the other hand, neuroimaging offers a platform for educational advancements that can enable each child to receive the type of reading instruction that best suits his or her mind and brain.
