Aphasia. This is a disorder that impacts the way a person comprehends, speaks, and writes language. Aphasia usually is a result of traumatic head injury or stroke, but can have other causes such as tumors or progressive diseases. [18] There are several types of aphasia, with the two most popular being Broca’s Aphasia and Wernicke’s Aphasia.
Expressive aphasia (also known as Broca's aphasia) is a type of aphasia characterized by partial loss of the ability to produce language (spoken, manual, [1] or written), although comprehension generally remains intact. [2] A person with expressive aphasia will exhibit effortful speech.
Broca's area is located in the left hemisphere prefrontal cortex above the cingulate gyrus in the third frontal convolution. [16] Broca's area was discovered by Paul Broca in 1865. This area handles speech production. Damage to this area would result in Broca aphasia which causes the patient to become unable to formulate coherent appropriate ...
This evidence suggests that grammatical competence may be a specific function of Broca's area. [citation needed] Lesions exclusive to Broca's area (the foot of the inferior frontal gyrus) do not produce Broca's aphasia but instead mild dysprosody and agraphia, sometimes accompanied by word-finding pauses and mild dysarthria.
Broca's patients could no longer speak but could understand language (non-fluent aphasia) while Wernicke's patients could no longer understand language but could produce jumbled speech (fluent aphasia). Post-mortems revealed lesions in separate areas of the brain in each case (now referred to as Broca's area and Wernicke's area respectively ...
The discovery that aphasia takes different forms depending on the location of brain damage provided a powerful framework for understanding brain function. [3] In 1861, Paul Broca reported a post mortem study of an aphasic patient who was speechless apart from a single nonsense word: "Tan". Broca showed that an area of the left frontal lobe was
