Question 0

Wernicke’s aphasia

Answer 0

person has considerable difficulty comprehending speech and speaking in a meaningful way. Unlike someone with Broca’s aphasia, a person with Wernicke’s aphasia will often have fluent and grammatically correct speech, but what is said is nonsense.

or ‘string together’, a clearly spoken sequence of words or even proper phrases (fluent speech), but what they say is generally nonsense and not considered to be understandable language

Question 1

Broca’s aphasia

Answer 1

a person has difficulty speaking, although they continue to understand speech. Speech consists of very short sentences, typically three or four words, and these words are mainly verbs and nouns.
The small parts of speech, such as to and the, are omitted, as are proper grammatical endings of words, such as -ing and -ed. For example, if you were to ask someone with Broca’s aphasia what they did today, they might answer Went house
visit cousin.

Question 3
