Aphasia (Broca - Expressive)

Broca aphasia, also known as expressive aphasia, is a condition that affects the brain's ability to produce speech. It involves damage to a specific area in the left frontal lobe called Broca's area, which controls language expression. People with this condition understand language relatively well but struggle to form complete sentences and speak fluently. Their speech is often slow, effortful, and limited to short phrases. This condition primarily impacts the nervous system and communication skills, making it difficult for affected individuals to express their thoughts verbally. Despite speech difficulties, comprehension of spoken language is usually preserved. Writing ability may also be impaired similarly to speech.

Broca aphasia is a type of expressive aphasia characterized by impaired speech production due to damage in Broca's area located in the posterior inferior frontal gyrus of the dominant (usually left) hemisphere. The core pathology involves disruption of neural circuits responsible for motor planning of speech, often caused by ischemic stroke in the territory of the middle cerebral artery. Patients exhibit nonfluent, effortful speech with relatively preserved comprehension and awareness of their deficits. Repetition is typically impaired, and writing deficits parallel speech difficulties. This condition is clinically significant as it affects communication and quality of life but often spares language comprehension, distinguishing it from other aphasia types. Diagnosis and localization are supported by neuroimaging and clinical language assessment.
