Dyslexia or learning difficulties are of several varieties. It affects a child’s academic performance: Primarily their ability to read, write and spell. Dyslexia types are defined on the basis of the characteristics of the problem occurring within the brain or in the central nervous system. Trauma Dyslexia is one such type of Dyslexia and is associated with certain form of brain damage or an injury to that portion of the brain that controls the child’s ability to read and write. This Dyslexia condition results from severe head injuries and is a permanent brain injury that is rarely found in school going children.
Primarily, Dyslexia is a dysfunction of the left side of the brain and is believed to be genetic in nature as it is passed through the genes. This hereditary affliction is more apparent in boys. Such Dyslexia types are normally associated with individuals who rarely have the ability to read above fourth-grade and have a tough time with reading, spelling and writing. One of such Dyslexia types is termed as secondary or developmental type which is believed to be the result of poor hormonal development or malnutrition during the early signs of fetal development. This often is the result of poor parenting, abuse and neglect. But such Dyslexia types are known to be curable and diminish in intensity with growing maturity of the child. This, too, is more common in boys.
Secondary or developmental Dyslexia responds best in class rooms and children affected by this type of Dyslexia find themselves adaptable to the special educational sessions. It helps the child to learn while the central nervous system keeps developing. Among the Dyslexia types based on diverse functions are visual Dyslexia which is also termed as “visual processing disorder”. This affliction is a result of poor development of the eyes as well as the entire process that facilitates information gathering from the eyes to the brain. At times, children affected by such Dyslexia types face difficulties in writing accurately and the process may result in a number of letter reversals. The child has trouble writing symbols sequentially.
Another known Dyslexia type is related disability in auditory processing and is defined as “phonological Dyslexia”. A more severe type is termed as “auditory processing disorder”. Children / adults suffering from such Dyslexia types face problems in discerning sound of letters or group of letters. A child suffering from this affliction hears only “jumbled” sounds and cannot interpret them accurately. Other Dyslexia types – “Dyspraxia” refers to learning disorder that is wide spread and is a motor condition characterized by immaturity of sensor motor integration. It results in impairment of movement and associated problems of speech, thought and perception. Children suffering from this form of Dyslexia face dilemma when querying doubts as their questions appear poorly coordinated or clumsily structured.
“Dysgraphia” and “Dyscalculia” are other Dyslexia types that are wide spread amongst Dyslexic persons. The former Dyslexia type is noticed among children who are unable to hold or control a pencil resulting in poor pencil marking. The symptoms are apparent in poor formation of letters and below average cursive handwriting skills. The latter type “Dyscalculia” is apparent amongst those who are unable to solve mathematical calculations and this impairment results from brain dysfunction. Sufferers from such Dyslexia types also have poor time management skills, lacks in special reasoning and face difficulties with mathematical operations.
