Detailed explanation-1: -Broca aphasia is a non-fluent aphasia in which the output of spontaneous speech is markedly diminished and there is a loss of normal grammatical structure. Specifically, small linking words, conjunctions, such as and, or, and but, and the use of prepositions are lost.

Detailed explanation-2: -The most common type of nonfluent aphasia is Broca’s aphasia (see figure). People with Broca’s aphasia have damage that primarily affects the frontal lobe of the brain. They often have right-sided weakness or paralysis of the arm and leg because the frontal lobe is also important for motor movements.

Detailed explanation-3: -The most common cause of aphasia is brain damage resulting from a stroke-the blockage or rupture of a blood vessel in the brain. Loss of blood to the brain leads to brain cell death or damage in areas that control language.

Detailed explanation-4: -Fluent aphasia refers to deficits related to comprehension and is usually associated with Wernicke’s brain area pathologies. In contrast, nonfluent aphasias produce a failure in language expression, written or verbal, and are often associated with pathologies in Broca’s brain area.
