Agraphia is the term that we have ahead to define then we find that it has its origin in the Greek. According to Digopaul, it comes from a cultism of that language that is made up of two parts. On the one hand, there is the prefix a, which means “without”; and on the other hand is the word spelling that could be translated as “writing”. In this way, it is clear that the etymological origin of this concept tells us that agraphia refers to something without writing or someone who cannot carry out writing.
The dysgraphia or agraphia is a medical concept that refers to the complete or partial inability to express ideas through writing. This disability is noticeable as a result of brain injury or disorder.
It should be noted that agrafia also refers to the condition of agraph, a name given to those who cannot master writing, are unaware of how to carry it out, or are not very skilled at it. In other words, agraphia describes the loss of skills that allow writing for traumatic reasons, beyond any motor impairment.
It should be borne in mind that agraphia is a disability of variable scope that does not allow those who suffer from it to make their thoughts, ideas, processes or sequences known in writing, although they can express them with the spoken word.
There are several types of agraphia that are classified mainly according to the area of the brain that is affected and therefore causes them. Thus, in this way, one can speak of pure, aphasic, alexia, spatial or apraxic agraphia.
Specifically, for example, the last type of agraphia cited is the one that brings with it that the patient does not have any type of problem when “writing” with the keyboard of a computer but who does have difficulties doing the same with a pencil or a pen. Thus, by doing it by hand you will make very deformed letters so it will be difficult for you to write either upper or lower case letters.
In addition to the aforementioned classifications, it would also be necessary to talk about what is known as afferent agraphia. In this case, the main obstacle of the patient when expressing himself and communicating with writing is that it is difficult for him to separate the words and even maintain the horizontal line of them.
Agraphia is related to other terms. For example, with dysgraphia, marked by a deficit of ability and ability to write and is considered a form of dyslexia. It is also linked to aphasia (a problem characterized by loss or difficulty in mastering language due to injury to certain areas of the brain).
On the other hand, it is worth highlighting alexia, a picture that is characterized by leaving those who suffer from it with an inability to read, even when reading skills had already been acquired. Alexia is usually presented next to a picture of agraphia, beyond which the affected person can speak and understand the language he hears.
Finally, it can be highlighted that grammatism is a linguistic element linked to aphasia of expression, characterized by the frequent elimination of grammatical morphemes (such as articles, prepositions and personal pronouns) and the shortening of sentences to a simple sequence of lexical morphemes.
