Question 1
1. Critically, in a narrative and paragraph format discuss the effect of brain damage on
language abilities, providing examples, with specific reference to Broca’s and Wernicke’s
Aphasia.
Brain damage can have a profound impact on an individual’s ability to communicate, with
consequences that can range from subtle to debilitating. One of the most well-known consequences
of brain injury is aphasia, a disorder that affects language. Aphasia can result from damage to
specific areas of the brain and typically manifests in impairments in speaking, understanding, reading,
or writing. Two of the most prominent forms of aphasia are Broca’s aphasia and Wernicke’s aphasia,
both of which highlight different aspects of language dysfunction due to damage in distinct regions
of the brain. This discussion will critically discuss the effects of brain damage on language abilities,
with a focus on Broca’s and Wernicke’s aphasia, and explore their distinguishing characteristics,
underlying mechanisms, and broader implications.
Broca’s Aphasia
Broca’s aphasia, also known as expressive or non-fluent aphasia, is a disorder primarily affecting
speech production. This condition results from damage to Broca’s area, a region in the left frontal
lobe of the brain, which is crucial for speech production and grammatical processing (Kalat, 2023).
The symptoms of Broca’s aphasia vary in severity, but the hallmark of this disorder is difficulty in
articulating speech. Individuals with this condition typically exhibit halting, slow, and effortful
speech, often with a reduced word output. They may speak in short, fragmented sentences, referred
to as "telegraphic speech," where they omit small but essential words, such as articles, auxiliary
verbs, prepositions, and conjunctions. For example, a person might say “weather overcast” instead of
“the weather is overcast.” This lack of closed-class words results in a phenomenon known as
agrammatism, where grammatical structures like tenses and plurals are omitted (Lone Star
Neurology, 2023).
Despite the impairment in speech production, individuals with Broca’s aphasia usually have
relatively preserved comprehension. They are typically able to understand simple sentences and can
follow straightforward conversations. However, when the sentences become more complex,
particularly those with multiple clauses or ambiguous structures, comprehension becomes more
difficult (Brennan, 2021). For example, a person with Broca’s aphasia might struggle to understand
the sentence “The girl that the boy is chasing is tall,” because the syntactic structure is more complex
and requires understanding embedded clauses.
In addition to the difficulty in expressing themselves, people with Broca’s aphasia often experience a
high level of frustration due to their inability to communicate effectively. This is in part because they
are generally aware of their language deficits, unlike individuals with other types of aphasia
(Association, 2025). Nevertheless, their cognitive abilities, such as memory and intelligence, are
typically intact. This means that while their speech may be severely impaired, their ability to think,
reason, and remember is not generally affected.
