The term before us to define we find that it has its origin in the Greek. It comes from a cultism of that language that is composed 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 agrafia refers to something without writing or to someone who cannot carry out the writing.

The agrafia or agraphy It is a medical concept that refers to the complete or partial impossibility for manifest ideas through writing . This inability becomes apparent following a injury or of a brain type disorder .

It should be noted that agrafia also refers to the condition of ágrafo , name given to those who fail to master the writing, do not know how to carry it out or are not very skilled at it. In other words, the agraph describes the loss of skills that allow writing for traumatic reasons, beyond any motor alteration.

Keep in mind that agrafia is a disability of variable scope that does not allow the sufferer 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 agrafia that are fundamentally classified according to the area of ​​the brain that is affected and therefore originates them. Thus, in this way, one can speak of pure, aphasic, with alexia, spatial or apraxic agraphia.

Specifically, for example, the last type of aforementioned photography is that which brings the patient not to have any problem when "typing" with the keyboard of a computer but does have difficulties in doing the same with a pencil or a pencil. pen. Thus, when doing it by hand, you will make very deformed letters, so it will cost you a lot to write either uppercase or lowercase letters.

In addition to the aforementioned classifications, we should also talk about what is known as afferent agraph. In this case the main obstacle of the patient when expressing and communicating with writing is that it is difficult to separate the words and even maintain the horizontal line of them.

The photograph is related to other terms. For example, with the dysgraphia , marked by a deficit of ability and ability when writing and is considered as a form of dyslexia . It is also linked to the aphasia (problem characterized by loss or difficulty mastering language due to an injury in certain areas of the brain).

On the other hand, the alexia , a painting that is characterized by leaving who suffers with an inability to read, even when the ability to read was already acquired. Alexia usually appears next to an agraph box, beyond which the affected person can speak and understand the language he hears.

Finally, it can be noted that the agramatism It is a linguistic element linked to aphasia of expression, which is 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.
