The dysgraphia is a learning difficulty consisting of deficiencies that will cause the writing skills of a child is substantially fall below expected. Difficulties in understanding written text, grammatical errors, punctuation errors in the preparation of sentences, poor organization of paragraphs, spelling errors and poor penmanship are common.
Disorders of written expression are part of specific learning disorders and refer to the presence of writing skills below what is expected for the child's age, intellectual level and school year (Matute, Roselli & Ardila, 2010).
Written expression involves a set of motor skills and information processing skills that can be altered and, therefore, manifest as difficulties in spelling, handwriting, spacing, composition or organization of the text (Learning Disabilities Association of Ameria, 2016).
All alterations in written expression will significantly infer school performance and in all those activities that require writing as a fundamental tool (Matute, Roselli & Ardila, 2010).
Symptoms
The Learning Disability Association of America defines dysgraphia as the presence in children of writing difficulties when they do school work or activities that require the use of writing. It affects both writing ability and final motor skills (Learning Disabilities Association of Ameria, 2016).
A child with dysgraphia may have specific problems such as: hard to read handwriting, inconsistencies in the distribution of space, poor space planning, poor spelling and / or difficulty composing a text (Learning Disabilities Association of Ameria, 2016).
In this way, these are some of the signs and symptoms that we can identify in writing (Learning Disabilities Association of Ameria, 2016):
- Illegible or italic writing.
- Mix of different strokes, lowercase-capital letters, irregular sizes or shapes and / or inclination of the letters.
- Unfinished or omitted words or letters.
- Uneven space between words and / or letters.
- Abnormal position of the wrist, body or paper.
- Difficulty in copying letters, pre-visualization.
- Slow and difficult writing.
- Distribution of space on paper.
- Unusual pencil grip.
- Difficulty taking notes when dictating or creative writing.
Causes of dysgraphia
In general, as in other learning disorders, we can consider that there are genetic, neurobiological, perinatal and environmental etiological factors.
Neurological level
At the neurological level, different investigations have shown that there is not a single region responsible for writing, but that the development of this activity is achieved through a wide network of cortical regions.
In this way, depending on the different stages that make up the act of writing, we can highlight the participation of different verbal areas in the brain (Matute, Roselli & Ardila, 2010):
- Message perception and compression: bilateral primary auditory cortex, left associative temporal cortex and occipital areas.
- Transcoding of the message: angular gyrus and supramarginal gyrus.
- Motor act: sensory areas, associative motor cortex, hippocampus, prefrontal zones.
Various authors suggest that the origin of written expression disorders can be found in a dysfunction of the right cerebral hemisphere. However, others assume that it underlies language alterations mediated by the verbal left hemisphere (Matute, Roselli & Ardila, 2010).
Does dysgraphia disappear in adults?
The American Psychiatric Association (2003) has indicated that currently there is little information about the long-term evolution of these disorders.
Generally, it tends to persist throughout the primary and secondary school stage, and sporadically it can also be observed in older children or adults (Matute, Roselli & Ardila, 2010).
From an early age, alterations in written expression can be observed, generally in calligraphy, while in older children the deficiencies will be mainly related to text composition skills and the expression of ideas (Matute, Roselli & Ardila, 2010).
Types of dysgraphia
We can make classifications of written expression disorders based on the type of writing subsystem that is affected or presents difficulties: motor digraphs, dysorthography, other disorders of written expression.
Motor dysgraphia
Difficulties in the motor mechanisms involved in the graphic line: pencil pressure, position, posture of the body, lines, coordination, spatial organization, rhythmic movements.
Dysorthography (developmental dysgraphia)
Difficulties in acquiring spelling - substitution, omission, exchange of letters, substitution of phonemes, etc.-
Other disorders of written expression
Spacing between words, punctuation, grammar, coherence of the texts.
Despite this classification, it is very common to find written expression disorders grouped under the generic heading of dysgraphia.
Treatments for dysgraphia
With early and appropriate intervention, it is possible for most children with dysgraphia to achieve efficient and functional execution of their writing.
In the intervention with this type of alterations we can use different strategies:
- Accommodation: provide alternatives to written expression -oral evaluations-
- Modification: making changes to expectations and tasks to avoid a loss of confidence and self-esteem.
- "Treatment": is the fundamental intervention, providing strategies to improve writing and error correction skills.
Although there are different approaches to the intervention of this disorder, it is usually intervened through educational programs. These usually attend to the specific alterations in the writing that the student presents, together with the cognitive areas that may present a lower performance than expected (Matute, Roselli & Ardila, 2010).
It is frequent that in the case of the youngest children it is fundamentally intervened in the motor and calligraphic aspects, while in the older children textual aspects that facilitate their academic performance are usually worked on (Matute, Roselli & Ardila, 2010).
Relationship between written expression and dysgraphia
Although most children do not usually present significant difficulties in writing, more and more problems in written expression are being detected, many of which may be due to both the educational system, family environment, socioeconomic status and even neurobiological factors and genetic (Ventura et al., 2011).
Writing is a fundamental tool in daily life; allows us to express ideas and knowledge. In addition, it is not an easy process to acquire, until it reaches an optimal level of automation, it requires continuous practice and the provision of various cognitive resources (Ventura et al., 2011).
To achieve legible handwriting, spelling without errors, or to construct a text with a coherent structure, it is essential that we master several writing subsystems (Matute, Roselli & Ardila, 2010):
- The graphic stroke.
- The graphic composition of the word and the spelling aspects.
- The separation between words.
- The orthographic accent.
- The score.
- The grammar.
- The coherence between the texts.
Cognitive reading prerequisites
On the other hand, there will also be a series of cognitive prerequisites when it comes to learning to write (Matute, Roselli & Ardila, 2010):
- Language and metalanguage: a minimum linguistic level will be necessary to build compositions - phonological skills, semantic aspects, unit processing.
- Memory and attention: efficient control of attention resources will facilitate the task of selecting important elements, and on the other hand, working memory will allow us to keep the topic of the text. In addition, long-term memory will allow us to recover all semantic knowledge regarding the construction of language.
- Reading: writing and reading will share processes, however a good reader child will not necessarily also be a good writer.
- Executive functions: they will be essential for the planning and organization of the text, for the selection of the appropriate construction strategy and also, the simultaneous handling of all linguistic subsystems.
- Affective variables: different clinical reports have related variables such as anxiety, concern and motivation with writing.
Associated pathologies
It is not strange to observe the alterations in written expression associated with other specific learning disorders (Matute, Roselli & Ardila, 2010):
- Reading learning disorder.
- Stone disorder or dyscalculia.
- Language deficit.
- Perceptual deficit.
- Deficit in motor skills.
In addition, it is also possible to observe alterations in written expression in many children affected by attention deficit hyperactivity disorder (ADHD) or delayed mathematical performance.
