Types of Aphasia
a language disorder that is usually caused by damage to the left side of the
brain, can make it difficult for a person to understand spoken or written
information. It can also affect a person’s ability to speak or write. There are
several different types of aphasia:
with Wernicke’s aphasia often have serious comprehension difficulties. A person
may say meaningless words that don’t make sense and may not realize these words
are wrong. For example, a patient may call an apple a "dortog."
Broca’s aphasia, which often occurs as the result of a stroke, makes it
difficult for a person to form complete sentences, understand sentences and
express him or herself. A person may leave basic words out of sentences, making
it hard to communicate with others
aphasia often results from a stroke and makes it difficult for a person to
understand and form words and sentences. Global is different from broca's aphasia
because persons with global have more difficulty with comprehension. Also, broca's
is secondary to injury to the frontal part of the left side of the brain, while
global results from damage to frontal and back portions of the left side of the
Conduction aphasia (also called associative
aphasia) is a rare form of aphasia that is usually
called by damage to the left side of the brain, most usually a stroke. A person may have good
comprehension and speech but cannot repeat correctly what is said. A person may
also transpose words so that they do not make sense.
Transcortical Motor Aphasia
aphasia often results
from a cerebrovascular accident or stroke. A person usually has good
comprehension but can only say a sentence one or two words long and has
difficulty writing. However, a person can often repeat words or sentences.
Transcortical Sensory Aphasia
Sensory aphasia is also due to damage to the left side of the brain, most
usually a stroke. Deficits include poor comprehension, difficulty understanding
others and naming. However, patients usually speak at a normal or rapid
rate and will be able to repeat what others say.
Mixed Transcortical Aphasia
Mixed transcortical aphasia, the least common
of the three transcortical aphasias, is rare. A person may have severe speaking
and comprehension impairment, but can repeat long sentences or songs.
People with anomic aphasia have difficulty
finding the right words for speaking and writing. For example, a person may
know exactly what he or she wants to say, but cannot find the words to use.
This can be very frustrating for both patients and caregivers.
