What is Aphasia?

New to this journey? Let us help!

a•pha•sia | noun | [uh-fey-zhuh]:

is a communication disorder that affects a person’s ability to process and use language.

It is a neurological condition caused by damage to the portions of the brain responsible for language, and it does not affect intelligence. Because language plays such a central role in our daily lives, aphasia can be very challenging. Individuals with aphasia may find it difficult to speak, understand speech, and read and write.

The type and severity of aphasia depends on the precise location and extent of the damaged brain tissue. Aphasia can range from mild—where a task like retrieving the names of objects is difficult—to severe—where any type of communication is almost impossible.

Researchers, physicians, and speech therapists have categorized aphasia into several main types.

Click the buttons below for more information about the most common types and exactly what is aphasia.

Anomic aphasia is the least severe form. Individuals with anomic aphasia are often unable to supply the correct words for the things they want to talk about—objects, people, places, or events. It’s sometimes described as having a word on the tip of one’s tongue. He or she usually understands speech well and is able to read adequately, but writing ability may be poor.

Broca’s aphasia is also referred to as nonfluent or expressive aphasia. This type of aphasia can be very frustrating, as a person with Broca’s aphasia knows what he or she wants to say, but is unable to accurately produce the correct word or sentence. Expressing language in the form of speech and writing will be severely reduced. The person may be limited to short “telegraphic” statements, with words like “is” or “the” left out.

Persons diagnosed with Wernicke’s aphasia are unaware that the words they are producing are incorrect and nonsensical. He or she may have severe comprehension difficulties and be unable to grasp the meaning of spoken words, yet may be able to produce fluent and connected speech. Reading and writing are often severely impaired as well.

Global aphasia, as the name suggests, refers to widespread impairment. This is the most severe form of aphasia and usually occurs immediately after a stroke in patients who have experienced extensive damage to the brain’s language area. A person with global aphasia loses almost all language function and has great difficulty understanding as well as forming words and sentences. People who are suffering from global aphasia may only be able to produce a few recognizable words, understand little or no spoken speech, and be unable to read or write.

Primary progressive aphasia, a sub-type of frontotemporal dementia, is a rare degenerative brain and nervous system disorder that causes speaking and language skills to decline over time. A person becoming symptomatic with primary progressive aphasia may have trouble naming objects or may misuse word endings, verb tenses, conjunctions, and pronouns. Unlike actual aphasia, which is the result of brain damage, primary progressive aphasia is a progressive type of dementia.

Mixed types of aphasia resemble a severe form of Broca’s aphasia because the person’s speech is sparse and laborious. However, unlike Broca’s aphasia, a person with mixed types of aphasia may also have limited understanding of speech and not be able to read or write beyond an elementary level.

New to the world of aphasia?

Don’t worry…you are not alone. At least 2,000,000 people in the United States have aphasia, and yet, so few people have ever heard of the condition. Many stroke survivors leave the hospital without ever knowing that they have something called “aphasia.” With these facts in mind, we’ve created an aphasia infographic that gives those who are new to aphasia some quick facts and figures as they begin their journey to reclaiming their communication, as well as some resources to provide hope and help.
