Aphasia is
a disorder of language, inability (or impaired ability) to use words (produce
speech) to express ideas and to understand the speech of other people, resulting
from damage to the parts of the brain that manage language.
Aphasia may
be caused by a stroke, brain tumor, brain infection, or dementia such
as Alzheimer's disease. In some cases, aphasia is a symptom of
epilepsy or other neurological disorder. According to the National Aphasia Association,
about 25% to 40% of people who survive a stroke get aphasia.
Some
of the common varieties of aphasia are:
Global
aphasia. This is the most severe form of aphasia, and is applied to patients
who can produce few recognizable words and understand little or no spoken
language.
- Broca's
aphasia.
- Mixed
non-fluent aphasia.
- Wernicke's
aphasia.
- Anomic
aphasia.
- Primary
Progressive Aphasia.
Affected
people often omit small words such as “is,” “and,” and “the.” For example,
a person with Broca's aphasia may say, “Walk dog” meaning, “I will
take the dog for a walk.” In contrast to Broca's aphasia, damage to the
temporal lobe may result in a fluent aphasia that is called
Wernicke's aphasia.
Receptive
language disorders
Receptive
language is a child's ability to understand and process spoken or written
language. Children may experience some or all of the following problems:
- Following
directions or completing instructions.
- Understanding
long or complex sentences.
- Understanding
the meaning and context of words and sentences.
- Recognizing
the difference between sounds.
- They
may appear to be not listening or ignoring you most of the time.
- They
may not keep up with classmates, either with school work or socially.
- They
may have behavioral problems or be acting up in class.
- They
may be easily distracted or drift off when listening to speech or stories.
- They
may appear to be forgetful. For example, they only complete part of an
instruction or remember part of a shopping list.
Expressive
language disorders
Expressive language
is a child's ability to express themselves and get their meaning across through
speaking or writing. Children may experience some or all of the following
problems:
- Poor
sentence or grammatical structure.
- Limited
content in their speech.
- Confused
meaning and grammar.
- They
generally use short, simple sentences.
- Difficulty
coming to the point.
- Problems
starting or participating in conversations.
- Difficulty
recalling or retelling information.
- Difficulty
completing oral and written narratives and/or assignments.
- Have
trouble finding the right words.
Family
members and friends can use the following tips when communicating with a person
with aphasia:
- Simplify
your sentences and slow your pace.
- Keep
conversations one-on-one initially.
- Allow
the person time to talk.
- Don't
finish sentences or correct errors.
- Reduce
distracting noise in the environment.
How Long Does it Take to Recover from Aphasia? If the symptoms of aphasia last longer than two or three months after a stroke, a complete recovery is unlikely. However, it is important to note that some people continue to improve over a period of years and even decades.
