A 75-year-old right-handed woman is brought to the emergency department for evaluation of right-sided weakness. Past medical history is significant for hypertension and diabetes, for which the patient takes amlodipine, chlorthalidone, and insulin. Temperature is 37.0°C (98.6°F), pulse is 95/min, respirations are 15/min, and blood pressure is 180/99 mmHg. On examination, right upper and lower extremity motor strength is 1/5. The patient has difficulty answering questions and appears to be frustrated by this inability to communicate. The patient is able to speak a few words, but the speech is non-fluent. She is able to comprehend 2-step instructions but is unable to repeat phrases. Which of the following best describes the type of aphasia observed in this patient?

Summary

Broca aphasia, also known as expressive aphasia, is a type of aphasia characterized by problems with spoken language (spoken or written). People with Broca aphasia may have difficulty producing speech, and their speech may be halting and effortful. They may also have trouble understanding spoken language. Broca aphasia may be able to speak single words or short phrases, but they have difficulty producing complex or grammatically correct speech. Broca aphasia is usually caused by damage to the Broca's area, which is located anterior to the primary motor cortex.
