Wernicke’s (receptive) aphasia is characterised by a lack of language understanding, but no deficit in language production. Patients demonstrate fluent speech, however, this speech lacks content or meaning. Wernicke’s aphasia can also be caused by a left MCA stroke.

Broca’s (expressive) aphasia is characterised by the loss of ability to produce fluent language while maintaining intact comprehension. This is most commonly caused by stroke or trauma to Broca’s area, which is in the lower premotor cortex of the language dominant hemisphere (most commonly the left side). Broca’s area is supplied by the middle cerebral artery (MCA), so strokes involving the left MCA commonly cause this language deficit.

Apraxia is a motor disorders characterised by the inability to create and sequence effective motor plans. This often involves pauses, elongation, repetition, silent voicing, abnormal rhythm and intonation. Speech apraxia can be caused by stroke, however, Broca’s (expressive) aphasia is far more commonly seen.

Dysarthria is the inability to properly move the mouth and tongue muscles to produce speech. This can be caused by stroke, however, the patient's deficit in this scenario is with fluency, not word formation.

Amnesia is a symptom of memory deficit, not language production deficit as described here. There are multiple different types of amnesia, which are mostly associated with damage to the medial temporal lobe, which more commonly occurs due to head trauma, neurodegenerative disease, drugs or vitamin B12 deficiency than ischaemic stroke.

A 69-year-old patient is recovering from an ischaemic stroke involving his left middle cerebral artery. His comprehension remains intact, but he struggles to produce fluent language. The words he produces are formed and phonated normally.

Which of the following is the most likely barrier to communication that this patient is experiencing?
