In very severe forms of expressive aphasia, a person may only speak using single word utterances. [4] [5] Typically, comprehension is mildly to moderately impaired in expressive aphasia due to difficulty understanding complex grammar. [4] [5] It is caused by acquired damage to the frontal regions of the brain, such as Broca's area. [6]
Aphasia, also known as dysphasia, [a] is an impairment in a person’s ability to comprehend or formulate language because of damage to specific brain regions. [2] The major causes are stroke and head trauma; prevalence is hard to determine, but aphasia due to stroke is estimated to be 0.1–0.4% in developed countries. [3]
Strokes may occur when blood flow to the brain is completely interrupted or severely reduced. This has a direct effect on the amount of oxygen and nutrients being able to supply the brain, which causes brain cells to die within minutes.
They had lost the ability to speak after injury to the posterior inferior frontal gyrus (pars triangularis) (BA45) of the brain. [7] Since then, the approximate region he identified has become known as Broca's area, and the deficit in language production as Broca's aphasia , also called expressive aphasia .
Also known as a cerebrovascular accident (CVA); caused by a lack of blood to the brain, resulting in the sudden loss of speech, language, or the ability to move a body part, and, if severe enough, death. Stuttering Frequent repetition of words or parts of words that disrupts the smooth flow of speech. Sudden deafness
SLPs may also help these individuals to speak more slowly and to manage the physical tension involved in the communication process. Fluency may be developed by selecting a slow rate of speech, and making use of short phrases and sentences. With success, the speed may be increased until a natural rate of smooth speech is achieved.

A child’s brain uses the most energy around age 5, when it uses up to two-thirds of a child’s resting energy expenditure. This is also an age where kids typically lose weight.
Neuroscience of multilingualism is the study of multilingualism within the field of neurology.These studies include the representation of different language systems in the brain, the effects of multilingualism on the brain's structural plasticity, aphasia in multilingual individuals, and bimodal bilinguals (people who can speak at least one sign language and at least one oral language).
