The brain is wired contralaterally, which means the limbs on right side of the body are controlled by the left hemisphere and vice versa. [16] Therefore, when Broca's area or surrounding areas in the left hemisphere are damaged, hemiplegia or hemiparesis often occurs on the right side of the body in individuals with Broca's aphasia.
Damage to Broca's area is commonly associated with telegraphic speech made up of content vocabulary. For example, a person with Broca's aphasia may say something like, "Drive, store. Mom." meaning to say, "My mom drove me to the store today." Therefore, the content of the information is correct, but the grammar and fluidity of the sentence is ...
Broca's aphasia is a specific type of expressive aphasia and is so named due to the aphasia that results from damage or lesions to the Broca's area of the brain, that exists most commonly in the left inferior frontal hemisphere. Thus, the aphasia that develops from the lack of functioning of the Broca's area is an expressive and non-fluent aphasia.
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. The different types of aphasia all have different impacts on the comprehension and production of ...
Broca's fissure is a medical and scientific term for a sulcus occurring in the area of the brain known as Broca's area. [1] Broca's area contains the motor speech area and controls movements of tongue, lips and vocal cords. Broca's fissure produces the typical effects of a lesion in Broca's area (i.e., expressive aphasia).
Disconnection syndrome can also lead to aphasia, left-sided apraxia, and tactile aphasia, among other symptoms. Other types of disconnection syndrome include conduction aphasia (lesion of the association tract connecting Broca’s area and Wernicke’s), agnosia, apraxia, pure alexia , etc. [ 4 ]
paralysis of a limb (monoparesis) or a larger area on one side of the body (hemiparesis) paralysis head and eye movements; inability to express oneself linguistically, described as an expressive aphasia (Broca's aphasia) focal seizures that may spread to adjacent areas (Jacksonian seizure) grand mal or tonic-clonic seizures
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 ...
