Aphasia is a problem with speech, writing, or understanding language. This happens when it damages parts of the brain that contribute to speech development. Areas of brain language include frontal lobe temporal lobe and parietal lobe.
The frontal lobe controls your cognitive (thinking) skills, the temporal lobe processes memories, and the parietal lobe is responsible for information about taste, touch, movement, and temperature.
Language function is found in a hemisphere (half) of the brain, called the dominant hemisphere. As a rule, dominant cerebral hemisphere it’s on the opposite side, like your dominant hand (the hand you write).
Aphasia can occur as a result of any brain injury, such as cerebral haemorrhage. traumatic brain injury, brain tumor, or brain infection. Because of the way blood vessels are located in the brain, the most common cause is afasias it’s a stroke.
This article will address three types of aphasia that can occur with a stroke.
What Is Aphasia?
Aphasia can affect language in many ways because there are several regions of the brain that control language. When one area of language is damaged but other areas of language remain healthy, some language functions may be affected, while others remain the same.
For example, people with aphasia may have difficulty pronouncing words. They may have trouble understanding the language or may have difficulty reading or writing.
There are a number of well-known aphasia syndromes that have their own specific characteristics of speech and language. These patterns refer to areas of the brain damaged by a stroke. The three most common types of aphasia are:
- Bit Aphasia
- Wernicke’s Aphasia
- Global aphasia
Fifteen percent of people under age 65 who have had a stroke develop some type of aphasia. Almost 45% of people over 85 experience it.
Bit Aphasia / Motor aphasia
This form of aphasia is named after the person who discovered the area of the brain responsible for the creation of speech. Brock’s aphasia is sometimes called ” motor aphasia.” The term is used to show that the ability to speak is impaired, but other language skills remain basically the same.
Damage to the broca area occurs when a stroke disrupts blood flow the dominant frontal lobe of the brain. In general, Brock aphasia prevents a person from forming clear words or sentences. But it practically does not affect the ability to understand others when they speak.
If you have broca aphasia, you may feel frustrated because you can’t turn your thoughts into words. Some people who have had a stroke with aphasia may say just a couple of words to express their thoughts. Experts call this type of language telegraphic speech.
Some blood vessels affected by broca aphasia also supply blood to areas of the brain that control movement on one side of the body. This usually happens on the right side.
For this reason, broca aphasia is often accompanied by other problems after a stroke. These problems include hemiparesis (weakness) or hemiplegia (paralysis) on the right side of the body, Alexia (inability to read), and agraphia (inability to write).
Brock’s aphasia makes it difficult for a person to express himself, but he is usually able to understand language. Because strokes that cause broca aphasia often damage other areas of the brain, people may also have difficulty moving, reading, and writing.
Wernicke’s aphasia is named after the person who discovered the areas of the brain responsible for our ability to understand language. These areas are located in the temporal lobe. People with Wernicke aphasia cannot understand others, or even themselves, when they speak.
Wernicke’s aphasia discourse, however, is impossible to understand. Stroke survivors suffering from Wernicke aphasia create sentences with randomly arranged words. This type of language pattern is sometimes called logorrhea.
When someone experiences Wernicke aphasia, they may say something like, ” my door sat through a lamp in the sky.” This makes it impossible for listeners to understand what the person is trying to communicate.
When people with Wernicke aphasia talk, they usually feel that other people should understand them. This is caused by his inability to realize the fact that his language is now weakened.
Patients with Wernicke aphasia may learn that others cannot understand them when they speak. As a result, they may become angry, paranoid, and depressed. Wernicke’s aphasia is one of the most emotionally challenging events after a stroke.
This is a type of aphasia that occurs when brain damage is so common that it affects both broca’s and Wernicke’s language areas. Survivors with global aphasia cannot understand spoken language or speak at all. In some cases, people with global aphasia can still communicate through written language.
Aphasia is a language disorder caused by damage to certain parts of the brain that control language. Trauma may occur as a result of cerebral haemorrhage. traumatic brain injury or brain infection (encephalitis).
The three types of aphasia are broca’s aphasia, Wernicke’s aphasia and global aphasia. All three interfere with your ability to speak and/or understand language.
A Few Words From Get Meds Info
It’s not easy living with aphasia. It is important to participate in therapy, including speech therapy, as you recover from a stroke.
Stroke survivors and their loved ones benefit from understanding the subtle characteristics of aphasia. This can help improve your communication and facilitate recovery.
Frequently asked questions
Treatment of aphasia usually involves speech therapy. Helps improve a person’s ability to communicate in three ways:
- Help in the use of remaining language skills
- Regain language skills as much as possible
- Learn other ways to communicate (gestures, images, use of electronic devices).
Treatment can be done by individual therapy or group therapy, usually in a small group setting.
Expressive aphasia is a term sometimes used to describe Brock’s aphasia. This is because a person with broca’s aphasia is often able to speak short, meaningful sentences, but may not use the words ” and “and” the ” in their language. People with expressive aphasia can usually understand other people’s speech.
In susceptible aphasia, a person is able to speak freely, but may not understand what he or she is saying. Their speech may not make sense and they may not be able to read and write. Other names for this condition include Wernicke aphasia and fugitive aphasia.
The Brock area can be considered the speech center of the brain. The drill area, located in the frontal cortex, plays a vital role in communication.
