Lacking normal planum temporale leads to paucity of speech, including telegraphic speech. Which aphasia category is described?

Nonfluent (expressive) aphasia is characterized by limited, halting speech with telegraphic quality and agrammatism, where the person speaks mainly content words and omits function words. Comprehension is typically relatively preserved for simple sentences, though more complex syntax can be difficult, and repetition is often impaired. This pattern points to a disruption in language production networks, classically involving the left frontal regions around Broca’s area, rather than the language comprehension areas. Lacking the planum temporale would more directly affect language processing in regions near Wernicke’s area, where fluent, meaningful speech is produced despite comprehension issues. Since the description emphasizes paucity of speech and telegraphic speech (production problems) rather than fluent, meaningless speech with poor comprehension, the best fit is nonfluent aphasia.
