Which of the following is a symptom of Broca's aphasia?

Broca's aphasia is characterized primarily by difficulty in producing speech. Individuals with this condition often have intact comprehension, meaning they can understand spoken language relatively well, but they struggle to articulate their thoughts or find the right words. This results in slow, laborious speech that may lack grammatical structure, often referred to as "telegraphic speech."

In contrast, the other options describe symptoms that are not typical of Broca's aphasia. For instance, an inability to understand spoken words is more indicative of Wernicke's aphasia, where comprehension is impaired yet fluent speech is maintained. Problems with visual memory and the inability to read could be associated with different neurological conditions or lesions affecting other areas of the brain, such as the occipital or temporal lobes, rather than the left frontal area associated with Broca's aphasia. Therefore, the hallmark symptom of Broca's aphasia remains the difficulty in producing speech.
