Generally, aphasia is a term used to describe a communications disorder wherein the patient is unable to speak clearly, or speaks only haltingly. There are several types, in large part because the condition can arise from disorders in various parts of the brain.
Broca's aphasia was so named because Broca demonstrated that this common type of aphasia arose from a disorder in the left posterior frontal lobe of the brain.

Damage to Broca's area and Wernicke's area of the brain can cause?
Damage to Broca's area causes an expressive aphasia, whereas damage to Wernicke's area causes a receptive (although illogcally sounding fluent) aphasia.
What has the author Paul Broca written?
Paul Broca was a famous French physician and anatomist who is known for his research on the brain and his discovery of "Broca's area," a region in the brain linked to speech production. He is also known for his work on aphasia, a language disorder caused by brain damage.
What are the kinds of aphasia?
Aphasia is an impairment in the comprehension and/or production of language. The two main headings are fluent and non-fluent aphasia.WERNICKE'S APHASIAANOMIC APHASIACONDUCTION APHASIAUNUSUAL APHASIA SYNDROMESMIXED AND GLOBAL APHASIAThis is an addition to the above-mentioned answer.motor aphasia = caused by any damages to Broca's areasensory aphasia:auditory aphasia = caused by any damages to Wernicke's areavisual aphasia = caused by any damages to angular gyrusGlobla aphasia = caused by any damages or obstruction to "middle cerebral artery" which supplies the Broca's area, Wernicke's area and angular gyrus.
What is the difficulty producing the sounds for speech due to damage in the frontal lobe is called what?
Broca's aphasia
What part of the brain would a lesion most likely result in aphasia?
Broca's or Wernicke's area. --Allison
What is expressive aphasia?
Expressive aphasia is a neurogenic communicative disorder characterized by the inability to speak or verbally communicate. This disorder is typically associated with damage in Broca's area in the frontal lobe of the brain.
What kind of a lobe is it when a person can understand words but have problems with the expression of meaningful speech?
This is known as Broca's Area which is located in the Frontal Lobe of the Brain. Difficulty producing speech is known as Broca's Aphasia.

This is known as Broca's Area which is located in the Frontal Lobe of the Brain. Difficulty producing speech is known as Broca's Aphasia.
Damage to the broca's area and wernicke's area of the brain can cause?
Broca's and Wernicke's aphasia, respectively. Follow the link below for more details. -----The person might have difficulty finding the words to describe an event.
What happens when someone suffers broca's aphasia?
Broca's aphasia occurs when a patient suffers a brain injury that results in damage to the frontal brain lobe that controls language capabilities. As a result, patients encounter extreme difficulty with written and spoken language and are frequently unable to complete a sentence without extreme exertion of effort.
What function affects Broca's area?
Broca's area is the area of the brain responsible for speech production, language processing, and language comprehension, as well as controlling facial neurons. First discovered in 1861, Broca's area was named after Pierre Paul Broca. Broca discovered the area after studying the brain of a patient with a speech impairment after his death. Broca's area is connected to the Wernick's area of the brain by the arcuate fasciculus, which is a pathway made of neurons. It is found in the frontal lobe of the cortex, within the inferior frontal gyrus. It is comprised of two primary parts: the Pars triangularis and the Pars opercularis. The Pars triangularis is located in the anterior portion of Broca's area. Researchers believe that this area of the brain is responsible for helping the human brain interpret different stimulus modes. It is also where verbal conducts are programmed in the brain. The Pars opercularis is located in the posterior region of Broca's area. It is believed that this area supports only one stimulus mode, rather than multiple modes like the Pars triangularis. This portion of Broca's area is also thought to coordinate the organs used for speech in order to produce language. This conclusion has been drawn because the Pars opercularis of Broca's area is located near areas that are related to motor skills. If the Broca's area is damaged, the person is said to suffer from Broca's area aphasia. This condition is also called expressive aphasia, nonfluent aphasia, or motor aphasia. A person suffering from this condition is unable to put together sentences that are grammatically complex. In addition, the sentences typically contain very few words related to content. Despite the person's difficulty in putting together sentences, a person with a damaged Broca's area is generally capable of comprehending language without a problem. In some cases, however, the person may have difficulty with understanding a few words used in a sentence with complex syntax. These individuals typically have damage only in the posterior portion of Broca's area, a condition referred to as Wernicke's aphasia. Those suffering from Wernicke's aphasia may have somewhat normal speech, though it tends to be vague or even meaningless. Individuals who stutter have also been found to have a smaller Pars triangularis and a decreased overall amount of activity in the Broca's area. On the other hand, these individuals tend to have more activity in the right hemisphere of the Broca's area. It is believed that this increased activity is to compensate for the overall decrease.
What part of the brain is damaged during a stroke that impairs speech?
Speech impairment (aphasia) caused by stroke is mostly associated with damage to the Broca's area in the brain. This type of aphasia is called Broca's aphasia. However, many other types of aphasia may arise from neurological damage. Check the Wikipedia page for 'Aphasia' for more details.
