In progressive nonfluent aphasia, which feature is most affected?

Progressive nonfluent aphasia is defined by a breakdown in language production, with effortful, halting speech and grammatical impairment. The pattern arises from degeneration in left frontal language regions, leading to apraxia of speech (difficulty planning articulatory movements) and agrammatism (simplified, telegraphic syntax). Because these speech production and grammar problems are the hallmark of this condition, they are the most affected feature. Naming and comprehension can be variably affected but are not the defining issue early on, and memory for spatial details or social understanding are typically preserved in the initial stages. So the standout difficulty is in producing fluent speech with proper grammar.
