Aphasia Definition: Causes, 7 Symptoms, and Diagnosis

Aphasia Definition

Aphasia is a condition when a person has a breakdown in communication. This generally affects language, speech, reading, or writing skills.

This disorder generally occurs due to damage to the brain. Damage can occur suddenly, such as a stroke or head injury. However, this condition can also appear gradually due to the slow or progressive growth and development of diseases in the brain.

The severity of this condition can vary. A person can experience very mild aphasia, which affects only one aspect of communication, such as difficulty mentioning the name of an object, combining words into sentences, or the ability to read. However, this condition can also be so severe that it is almost impossible to communicate with the sufferer.

This communication disorder can happen to anyone, regardless of age. However, aphasia is more common in people over the age of 65, as the risk of stroke and progressive nervous system disease tends to affect older persons.

Aphasia causes

This disorder can occur when the part of the brain that regulates language skills, is damaged by injury or disease. These include strokes, brain tumors, and traumatic brain injuries. Aphasia can develop gradually in people suffering from progressive nervous disorders.

Early treatment for aphasia focuses on treating the underlying disease. For example, stroke patients are treated with the aim of smoothing blood flow to the brain. While brain cancer patients may need to undergo surgery to remove tumors in the brain. Speech and language therapy can be started right after the procedure.

There are two types of aphasia, namely smooth and not smooth. People with fluent aphasia can compose sentences that are quite long, but often with the wrong word. On the other hand, people suffering from aphasia┬ástruggle to express words and pronounce them in very short sentences. For example, it might just say, “want cheese” or “go restaurant.”

Aphasia Symptoms

There are several types of aphasia with different symptoms, namely:

Global aphasia

Global aphasia is the most severe type of aphasia. A person with global aphasia is only able to produce a few words that can be understood and cannot or only slightly understand when spoken to. These aphasia sufferers are neither able to read nor write.

Broca aphasia (non-fluent aphasia)

In this form of aphasia, speech is very limited and usually during the delivery of the language of the sufferer using short words (usually less than four words).

Vocabulary in Broca aphasia sufferers is very limited. Sufferers can generally understand the words presented to him quite well and are able to read, but are limited in writing.

Mixed non-fluent aphasia

In this aphasia, sufferers have difficulty saying words and a few words are spoken, similar to the severe state of Broca aphasia.

The difference is, the sufferer has difficulty understanding the words presented to him. Reading and writing skills are also very limited, similar to elementary school children.

Wernicke’s aphasia

In this aphasia, the production of words does not experience problems while the ability to understand the spoken word is impaired. As a result, sufferers generally speak using many words, creating long sentences, and often have no meaning.

Anomic aphasia

A person with this aphasia will have difficulty finding the words necessary to convey his or her meaning, often this word is a noun or adjective.

If spoken, the sufferer will use too many words, even if correct in grammar. Understanding words are generally not problematic.

Progressive primary aphasia

Progressive primary aphasia is a neurological syndrome in which language ability is slowly and progressively impaired. This condition is caused by neurodegenerative problems, for example, due to Alzheimer’s disease.

In this case, there is damage to brain tissue that serves for language ability. Although language problems begin, at an advanced stage there can be other problems, such as memory loss.

Other types

Other types include different types of aphasia that do not fully fall into the categories described above. There can be a combination of several types of aphasia.

Aphasia Diagnosis

To determine the diagnosis of aphasia a thorough evaluation is required by the doctor. The examination can be done to assess the ability to understand words, questions, stories; mention words and sentences; writing and reading; convey ideas in other ways if there is difficulty speaking (e.g. With gestures, and so on).

The presence of damage to the brain can be further examined by supporting examinations, for example through CT-scans or MRI.
