70 71 Central dyslexias Central dyslexias include surface dyslexia, semantic dyslexia, phonological dyslexia, and deep dyslexia. 18 72 icd -10 reclassified the previous distinction between dyslexia (315.02 in icd-9) and alexia (315.01 in icd-9) into a single classification as R48.0. The terms are applied to developmental dyslexia and inherited dyslexia along with developmental aphasia and inherited alexia, which are considered synonymous. 73 Surface dyslexia main article: Surface dyslexia in surface dyslexia, words with regular pronunciations (highly consistent with their spelling,. Mint ) are read more accurately than words with irregular pronunciation, such as colonel. 74 Difficulty distinguishing homophones is a diagnostic used for some forms of surface dyslexia.

63 The other mechanism is the nonlexical or sublexical route, which is the process whereby the reader can "sound out" a written word. 63 64 This is done by identifying the word's constituent parts proposal (letters, phonemes, graphemes ) and applying knowledge of how these parts are associated with each other, for example, how a string of neighboring letters sound together. 61 The dual-route system could explain the different rates of dyslexia occurrence between different languages (e.g. The Spanish language dependence on phonological rules accounts for the fact that Spanish-speaking children show a higher level of performance in non-word reading, when compared to English-speakers). 29 65 Dyslexia disorder is not caused by mutation in one gene; in fact, it appears to involve the combined effects of several genes. Studying the cognitive problems associated with other disorders helps to better understand the genotype-phenotype link of dyslexia. 66 neurophysiological and imaging procedures are being used to ascertain phenotypic characteristics in dyslexics, thus identifying the effects of certain genes. 67 diagnosis There are tests that can indicate with high probability whether a person is a dyslexic. 68 If diagnostic testing indicates that a person may be dyslexic, such tests are often followed up with a full diagnostic assessment to determine the extent and nature of the disorder. 69 Tests can be administered by a teacher or computer. 70 Some test results indicate how to carry out teaching strategies.

Bright Solutions What is Dyslexia?

54 several genes have been associated with dyslexia, including dcdc2 and kiaa0319 on chromosome 6, 55 and dyx1C1 on chromosome. 56 Geneenvironment interaction main article: Geneenvironment interaction The contribution of geneenvironment interaction to reading disability has been intensely studied using twin studies, which estimate the proportion of variance associated with a person's environment and the proportion associated with their genes. Studies examining the influence of environmental factors such as parental education 57 and teacher quality 58 have determined that genetics have greater influence in supportive, rather than less optimal, environments. 59 However, more optimal conditions may just allow those genetic risk factors to account for more of the variance in outcome because the environmental risk factors have been minimized. 59 As environment plays a large role in learning and memory, it is likely that epigenetic modifications play an important role in reading ability. Animal experiments and measures of gene expression and methylation in the human periphery are used to study epigenetic processes; however, both types of study have many limitations in the extrapolation of results for application to the human brain. 60 Mechanisms main article: dual-route resume hypothesis to reading aloud The dual-route theory of reading aloud was first described in the early 1970s. 61 This theory suggests that two separate mental mechanisms, or cognitive routes, are involved in reading aloud. 62 One mechanism is the lexical route, which is the process whereby skilled readers can recognize known words by sight alone, through a "dictionary" lookup procedure.

The cerebellum is also involved in the automatization of beauty some tasks, such as reading. 50 The fact that some dyslexic children have motor task and balance impairments has been used as evidence for a cerebellar role in their reading difficulties. However, the cerebellar theory is not supported by controlled research studies. 51 Genetics main article: Genetic research into dyslexia research into potential genetic causes of dyslexia has its roots in post- autopsy examination of the brains of people with dyslexia. 45 Observed anatomical differences in the language centers of such brains include microscopic cortical malformations known as ectopias, more rarely, vascular micro-malformations, and microgyrus. 52 The previously cited studies and others 53 suggest that abnormal cortical development presumed to occur before or during the sixth month of fetal brain development was the cause of the abnormalities. Abnormal cell formations in dyslexics have also been reported in non-language cerebral and subcortical brain structures.

45 neuroanatomy main article: neurological research into dyslexia modern neuroimaging techniques such as functional magnetic resonance imaging ( fmri ) and positron emission tomography (PET) have shown a correlation between both functional and structural differences in the brains of children with reading difficulties. 46 Some dyslexics show less electrical activation in parts of the left hemisphere of the brain involved with reading, such as the inferior frontal gyrus, inferior parietal lobule, and the middle and ventral temporal cortex. 40 over the past decade, brain activation studies using pet to study language have produced a breakthrough in the understanding of the neural basis of language. Neural bases for the visual lexicon and for auditory verbal short-term memory components have been proposed, 47 with some implication that the observed neural manifestation of developmental dyslexia is task-specific (i.e. Functional rather than structural). FMRIs in dyslexics have provided important data which point to the interactive role of the cerebellum and cerebral cortex as well as other brain structures. 48 49 The cerebellar theory of dyslexia proposes that impairment of cerebellum-controlled muscle movement affects the formation of words by the tongue and facial muscles, resulting in the fluency problems that are characteristic of some dyslexics.

37 35 of people with adhd have dyslexia. 10 Auditory processing disorder a listening disability that affects the buy ability to process auditory information. 38 39 This can lead to problems with auditory memory and auditory sequencing. Many people with dyslexia have auditory processing problems, and may develop their own logographic cues to compensate for this type of deficit. Some research indicates that auditory processing skills could be the primary shortfall in dyslexia.

40 41 developmental coordination disorder a neurological condition characterized by marked difficulty in carrying out routine tasks involving balance, fine- motor control, kinesthetic coordination, difficulty in the use of speech sounds, problems with short-term memory, and organization. 42 causes Inferior parietal lobule (superior view). Some dyslexics demonstrate less electrical activation in this area. Main article: Theories of dyslexia researchers have been trying to find the neurobiological basis of dyslexia since the condition was first identified in 1881. 43 44 For example, some have tried to associate the common problem among dyslexics of not being able to see letters clearly to abnormal development of their visual nerve cells.

27 :647 people with dyslexia are commonly poor spellers, a feature sometimes called dysorthographia or dysgraphia, which depends on orthographic coding. 10 Problems persist into adolescence and adulthood and may accompany difficulties with summarizing stories, memorization, reading aloud, or learning foreign languages. Adults with dyslexia can often read with good comprehension, though they tend to read more slowly than others without a learning difficulty and perform worse in spelling tests or when reading nonsense words a measure of phonological awareness. 28 Language main article: Orthographies and dyslexia the orthographic complexity of a language directly impacts how difficult learning to read the language. 29 :266 English and French have comparatively "deep" phonemic orthographies within the latin alphabet writing system, with complex structures employing spelling patterns on several levels: letter-sound correspondence, syllables, and morphemes. 30 :421 Languages such as Spanish, Italian and Finnish have mostly alphabetic orthographies, which primarily employ letter-sound correspondence so-called shallow orthographies which for dyslexics makes them easier to learn.

29 :266 Logographic writing systems, such as Chinese characters, have extensive symbol use, and pose problems for dyslexic learners. 31 Associated conditions Dyslexia is often accompanied by several learning disabilities, but it is unclear whether they share underlying neurological causes. 32 These associated disabilities include: Dysgraphia a disorder which primarily expresses itself through difficulties with writing or typing, but in some cases through difficulties associated with eyehand coordination and direction or sequence-oriented processes such as tying knots or carrying out repetitive tasks. 33 In dyslexia, dysgraphia is often multifactorial, due to impaired letter-writing automaticity, organizational and elaborative difficulties, and impaired visual word forming which makes it more difficult to retrieve the visual picture of words required for spelling. 33 Attention deficit hyperactivity disorder (adhd) a disorder characterized by problems paying attention, excessive activity, or taking action without forethought. 34 Dyslexia and adhd commonly occur together. 6 35 36 Either 15 10 or 1224 of people with dyslexia have adhd.

22 dsm 5, the manual of psychiatric diagnosis used in the United States, does not specifically define dyslexia, justifying this decision by stating dissertation that "the many definitions of dyslexia and dyscalculia meant those terms would not be useful as disorder names or in the diagnostic. Instead it includes dyslexia in a category called specific learning disorders. 23 Signs and symptoms see also: Characteristics of dyslexia in early childhood, symptoms that correlate with a later diagnosis of dyslexia include delayed onset of speech and a lack of phonological awareness, as well as being easily distracted by background noise. 10 A common myth closely associates dyslexia with mirror writing and reading letters or words backwards. 24 These behaviors are seen in many children as they learn to read and write, and are not considered to be defining characteristics of dyslexia. 10 School-age children with dyslexia may exhibit signs of difficulty in identifying or generating rhyming words, or counting the number of syllables in words both of which depend on phonological awareness. 25 They may also show difficulty in segmenting words into individual sounds or may blend sounds when producing gpa words, indicating reduced phonemic awareness. 26 Difficulties with word retrieval or naming things is also associated with dyslexia.

2 The British Dyslexia association definition describes dyslexia as "a learning difficulty that primarily affects the skills involved in accurate and fluent word reading and spelling" and is characterized by "difficulties in phonological awareness, verbal memory and verbal processing speed". 17 Acquired dyslexia or alexia may be caused milk by brain damage due to stroke or atrophy. 18 19 Forms of alexia include pure alexia, surface dyslexia, semantic dyslexia, phonological dyslexia, and deep dyslexia. 20 Definition There is some variability in the definition of dyslexia. Some sources, such as the. National Institutes of health, define it specifically as a learning disorder. 2 Other sources, however, define it simply as an inability to read in the context of normal intelligence, and distinguish between developmental dyslexia (a learning disorder) and acquired dyslexia (loss of the ability to read caused by brain damage). Icd 10, the manual of medical diagnosis used in much of the world, includes separate diagnoses for "developmental dyslexia" (81.0) 21 and for "dyslexia and alexia" (48.0).

more often diagnosed in men, 3 it has been suggested that it affects men and women equally. 11 Some believe that dyslexia should be best considered as a different way of learning, with both benefits and downsides. 13 14 Contents Classification Dyslexia is thought to have two types of cause, one related to language processing and another to visual processing. 15 It is considered a cognitive disorder, not a problem with intelligence. However, emotional problems often arise because. 15 Some published definitions are purely descriptive, whereas others propose causes. The latter usually cover a variety of reading skills and deficits, and difficulties with distinct causes rather than a single condition. 16 The national Institute of neurological Disorders and Stroke definition describes dyslexia as "difficulty with phonological processing (the manipulation of sounds spelling, and/or rapid visual-verbal responding".

3, it may begin in adulthood as the homework result of a traumatic brain injury, stroke, or dementia. 2 The underlying mechanisms of dyslexia are problems within the brain 's language processing. 4 Dyslexia is diagnosed through a series of tests of memory, spelling, vision, and reading skills. 5 Dyslexia is separate from reading difficulties caused by hearing or vision problems or by insufficient teaching. 3 Treatment involves adjusting teaching methods to meet the person's needs. 2 While not curing the underlying problem, it may decrease the degree of symptoms. 9 Treatments targeting vision are not effective.

Dyslexia, also known as reading disorder, is characterized by trouble with reading despite normal intelligence. 2 7, different people are affected to varying degrees. 4, problems may include difficulties in spelling words, reading quickly, writing words, "sounding out" words in the head, pronouncing words when reading aloud and understanding what one plan reads. 4 8, often these difficulties are first noticed at school. 3, when someone who previously could read loses their ability, it is known as alexia. 4, the difficulties are involuntary and people with this disorder have a normal desire to learn. 4, dyslexia is believed to be caused by both genetic and environmental factors. Some cases run in families. 4, it often occurs in people with attention deficit hyperactivity disorder (adhd) and is associated with similar difficulties with numbers.
