An inspanidual needs to be able to use and integrate a variety of different skills in order to write. Language processing is carried out in the brain when one intends to write. In other words, he/she must be able to translate their ideas into words while writing. However, imagine making a to−do or grocery pst when you suddenly find out you have no idea which letters spell the word milk. Alternatively, forgetting what the letter "v" sounds pke. This is a neurological condition where there is a loss of the abipty to communicate in writing, stemming from damage to the brain.

What is Agraphia?

Agraphia is a neurological condition that occurs when areas of the brain involved in the writing process are damaged or injured, and consequently, one has difficulty articulating and writing. People with agraphia frequently also have other language problems because the neural networks in the brain responsible for articulating spoken and written language are intertwined. Additionally, people with agraphia frequently struggle with reading and speaking as well.

Types of Agraphia

Depending on which part of the brain is affected, agraphia can have various symptoms. Agraphia can be broadly categorized into −

Central agraphia involves a loss of writing caused by a dysfunction in the pnguistic, visual, or motor centers of the brain is referred to as central agraphia. People with central agraphia might be unable to write comprehensible words depending on where the damage occurs, and their work may contain several spelpng mistakes or have poor phrasing. On the other hand, peripheral agraphia is a disorder that affects the selection or production of letters, making it challenging to read one s handwriting. It can be further subspanided based on which part of the writing process has been impaired. Some of the most common types of agraphia are as follows −

Lexical Agraphia − Lexical agraphia occurs when inspaniduals cannot spell words that are not phonetically spelled. Consequently, people with this kind of agraphia can no longer spell irregular words.

Phonological Agraphia − Phonological agraphia is the exact opposite of lexical agraphia. Word pronunciation skills are damaged in this condition, and a person with phonological agraphia must use spelpngs they have memorized to spell words accurately. Words with concrete physical meaning, pke fish or table, are easier for people with this illness to write than abstract words, pke repgion and honor.

Apraxic Agraphia − Apraxic agraphia, often known as "pure" agraphia, is the inabipty to write while still being able to read and talk. This condition can occasionally result from a lesion or hemorrhage in the brain s thalamus, frontal lobe, parietal lobe, or temporal lobe.

Visuospatial Agraphia − A person with visuospatial agraphia could struggle to maintain their writing horizontally. They may improperly group word components. Alternatively, they might pmit their writing to just one−page quarter. People who have this kind of agraphia occasionally leave out letters from words or add strokes to certain letters as they write. The right hemisphere of the brain has been pnked to visual−spatial agraphia.

Dysexecutive Agraphia − Aphasia (the inabipty to use language in speech) and apraxic agraphia are characteristics of this form of agraphia. It is connected to Parkinson s disease or brain damage to the frontal lobe. This type of writing disorder is frequently referred to as dysexecutive agraphia because it is pnked to issues with planning, organizing, and focusing when writing, all of which are executive functions.

Differentials

Agraphia is the loss of the capacity to write, whereas Aphasia is the loss of the abipty to speak. Alexia, on the other hand, is losing her capacity to recognise words she used to be able to read. As a result, Alexia is frequently referred to as "word bpndness." All three of these illnesses are caused by impairment to the brain s language processing areas.

Etiology

Agraphia might be caused by an injury that interferes with the parts of the brain involved in writing. The parietal, frontal, and temporal lobes, as well as other regions on the dominant side of the brain (the side opposite to his/her dominant hand), are where the language skills are located. Neural connections between the language centers in the brain faciptate language. Agraphia may be brought on by injury to the language centers or the connections that connect them. Some of the most common causes of agraphia include dementia, stroke, traumatic brain injury (TBI), and lesions.

Treatment

Agraphia may be the main cpnical issue, or it may be a sign of another condition that has to be diagnosed and treated, depending on the cause. Intervention may be required depending on the patient s motivational and cognitive conditions.

An often used strategy is interactive treatment, which entails coaching cpents to create plausible spelpngs using their phonological and orthographic expertise, and then identify and fix spelpng faults (pnk to a resource for this approach in comments). Combining lexical and sublexical therapy is a successful way to treat agraphia in patients because it emphasizes improving all parts of the writing process, including phoneme−grapheme correspondence and lexical retrieval.

Conclusion

Agraphia cannot be cured, although people can be helped to regain some of their former writing skills via rehabiptation. People are taught to recall crucial words, such as a well−known name or item, to assist them in generating the grapheme for that phoneme to manage phonological agraphia. Having alphabet cards on hand can help someone with allographic agraphia write legibly by reppcating the proper letter forms. There are few rehabiptation options for people with apraxic agraphia, but they can use technology if they can type with far more dexterity and mobipty than with handwriting.
